Tamiya TXT-1 v1.0

[bluesy]

Mason.... I really wish I had a digital video camera..... then I could show you how well this sweetheart climbs. Yep, no "staged" pix here..... I only took them after I made it up there. the first one is pretty tricky..... low speed and steady throttle.

ROCKS ROCK........:cool: :cool:

[RCtinkerman]

Usagi, What's up guy? Well I had duty all day yesterday, and being that it was Sunday, I was compelled to relax. So I bought my TXT-1 to work and put it together. You guys are right, that truck is BADDDDDD!!!!!! Only thing, how do you keep those dang rods from coming off. Jeep, Hairball, I know you guys have a fix. But heck it is so much fun everybody was running it. Now for the hop-ups:p Usagi, I'll be up your way probably next weekend to hunt for hop-ups.

[RCtinkerman]

Hey, you guys have got to see this, it came the Monster truck Forum. Move over T-Maxx, there's a Crusher coming through :eek:

http://www.clickonpc.com/rcdoc/videos/tug.mpg

[Usagi]

Hi tinker, let me know when you be up this way. Well get together (I hope). See you then.:)

[Mason Copeland]

bluesy:What motors were you running when you shot those?

[bluesy]

Mason..... Stock motors.... everything in the truck is stock except for the mickeymouse sway bars retainers..... It took a bunch of attempts but I made it. I realize that others can find ways to improve this big fella but I like it the way it is. It does everything I want it to do..... :cool: :cool:

[Mason Copeland]

Aaahhhhhh, so the stockers are good for something.

What batts?

[bluesy]

I'm using 2400 stick packs with the occasional 3000 pack... I get about 20 to 25 minutes of run out of the 3000 and about 15 to 20 minutes from the 2400's. I have 4 2400's and 3 3000's so I can have a good long bash when it quits raining long enough to go and play. ****at least there is no snow here**** :cool: :cool:

[RCtinkerman]

Thanks Jeep that's exactly what I was referring to. Question, I took the spacers off when I replaced the lower arm connector, it allows more thread for the connector. It seems to run ok, I hope this doesn't cause another problem until I can work that fix you suggested. Thanks:)

Duty? What service are you in man?

As for fixing the rods from comming apart, LOCTITE! What I did was take everyone of them apart (all eight), and thread the screw into the plastic ball cup first as far as it would go (with loctite), and once those dry, loctite and thread into the aluminum parts. I use the blue loctite, and havent had one come apart yet. :)

[RCtinkerman]

Hairball thanks, I'll give that a try first. I'm in the Navy, I have duty every 6 days. Means I have to be at work on call for 24 hours. Little happens on Sunday, so I put my TXT-1 together. It took me about 12 hours on and off.

[Usagi]

Tinker is a mean little dude, watch what you say he might attack you:)
He is a nice guy.:p

[Fetztang]

ttt! gotta get you guys posting again this truck rules

[Hairball]

Just got back from my first *real* outing with the TXT-1 / E-Maxx transmission / E-Maxx drivelines / EVX Speed Control / Titan 550 motors combo. Took it down to the beach.

All I can say is "why didn't I just do this in the first place"?

Motors don't get hot. TONS of power. 2 Speed tranny gets the thing MOVIN! And with low gear, I can climb all over the place without problems.

I was running two 2000 packs.

[Hairball]

Now that you mention it, I think I already did once.

Ok, from now on, I will refer to my rig as the "TXT/Maxx-1" :D

[RCtinkerman]

I love this truck:p

I can't wait for my motors to get here so I can lay a beating on this thing! :D

Jay

[RCtinkerman]

Blurredvision, that looks great. I got my skid plate from ballistic Studity. Their pretty good. I'm planning to order more stuff as they produce it. I,m a satisfied customer:D

[murf]

Yeah, got the thing all together...took about 5 days, 3 hours a night...the suspension is awesome!!! Set up a stack of logs by the fireplace and the thing just crawled right over them, then a pillow climb onto the sofa, launch off the end...sweet landing, then slam into the dining room table...hooked the back wheel and broke the upright (part D2) where it connects to the tie rod end!!! I have it glued up for now, I was bummed out to see that this is a part from the Clod, how old is that design??? I put my Clod thru hell and never had this part break, I guess cause the servo savers are on both ends...anyone else have the same prob?
Thanks,
Murf

LOL, toldja you'd love it! ;)

I'm sticking an E tranny in another vehicle...my current gear ratio in first is 180:1 :D

That's gonna be a cool lil' crawler ;)

Jason

[Hairball]

How in the world did you get that low of a gear ratio?

[RCtinkerman]

Oh boy tink your in deep know bro nice truck. did you get the speed control you wanted?

Usagi, No, I wanted to put the EVX in but I still have to order it. I had a new Futaba MC330cr in the tool box and was so excited to get the thing running, I put it in for now. I wired the those 21's I bought in parallel like Jeep said, and the thing runs great. Now all I need is some time off to play with it.:p

[RCtinkerman]

By the way Usagi showed me a place in Tokyo where they have the new Tamiya Aluminum cantlevers (blue, 1 pair) hop-up. They cost 3300 yen, which is about $25.00 US ;)

[Usagi]

How are the motors tinker?The 330cr is fine for now no problems.I using the 220cr in my micro.let get toether some time in a couple weeks.

[RCtinkerman]

The motors are great! I got decent speed and no heating problems. Actually Usagi I was thinking about tomorrow. I'll e-mail you.:)

[RCtinkerman]

Ok, I'm here

[Usagi]

tink you there?

[RCtinkerman]

You seen those vidoes on the Tera Crusher?

[RCtinkerman]

Where are you?

[Usagi]

on the tamiya site yes!!!!!!!!! they are way cool!

[RCtinkerman]

Have you seen them in the hobby shop yet. I wonder how much they cost/

[Usagi]

i was there yesterday, but i did not see them yet

[RCtinkerman]

I gotta get one next. What's your next project?

[RCtinkerman]

Actually, next week is better anyway, I get my allowance and then I can buy something.

[Usagi]

holy crap you joking!

[RCtinkerman]

Usagi, you type slow man:o

[RCtinkerman]

About what? Getting an allowance or buying something?

[Usagi]

can`t believe your buying another truck.... I am try to find a real time chatroom

[RCtinkerman]

Wifey has us on a strick budget. The allowance I get is pretty good. Remember I bought that truck on it.

[Usagi]

do you yahoo messager?

[RCtinkerman]

Yo, I didn't say anything about buying another truck next week. I'll have to save a couple of weeks for it. Next week I'll be looking for hop-ups.

[RCtinkerman]

Yes I have a yahoo acct.

[RCtinkerman]

Usagi, I'm on a Gov't computer at work. That doesn't work on it.

[Usagi]

WOW i thought you were going to buy next week!!!!!!!!!! do you have yahoo messager? i have it

[RCtinkerman]

Let me try the chat room again.

[Usagi]

oh......... let me check about the cost of the terra crusher now

[RCtinkerman]

It's not working, I gotta go. Talk to you later Usagi

[Usagi]

sure see you later

[Hairball]

Guys, please reframe from using this thread as a chat room in the future. :)

[Usagi]

sorry, but tinker could not get in the chatroom

[RCtinkerman]

Does anybody know if there are aftermarket dampers for the TXT?

[Hairball]

You mean shocks right? I'm using GPM oversized 4" shocks on mine. They are anodized blue, threaded, and just plain kick ass.

But they do run about $60 a pair ($120 for the whole truck).

Jeep uses Losi truck shocks on his.

My other opinion is that tamiya isn't a very good R/C company. I mean just look at their stuff. What do they have that is cool?


What do they have that isnt cool?????? They have alot of original stuff and they are like the grandfather MAC DADDY of RC!!

[atm92484_3]

Remember the TXT 1 needs no chassis upgrades like its predecessors the Clod and Juggs did. So what if it includes cheap electronics? Its enough to get you started. For $350 (yes Tower does have them for $350 now), its one of the best deals in electric monster trucks. Heck, next $350 I have I might buy one.

-also consider people were paying $250 for a Clod with the same electronics, then paying another $200+ for chassis upgrades and such

jmo

[Hairball]

Besides, it not about how much its going to cost you, its about how much fun your going to have with it! :)

Its a Hobby, not an investment. There is no way I could get the money I've spent on my TXT-1 back if I sold it. But I have so much fun with it, I really don't care. :)

Heck, the Wife doesn't even care, she says it keeps me out of trouble, so I can spend whatever I want on it.

And who says $1400 is a lot to spend on a toy anyway?

[bluesy]

Hairball..... I agree with you. It's not the cost of the toys.... it's the toys themselves. I haven't had as much fun with any type of RC vehicle since I got the TXT-1. I bought an E-Maxx (used) shortly after I got the TXT and now wish I had saved my money for new motor and better ESC(s) for the TXT. Frankly, the E-Maxx is boring. I seems like its just a buggy on steroids. (wow watch the flame wars start now) {but I only want to hear from those who own (or have driven) both vehicles**.

I want to upgrade the shocks from stock to ?????... suggestions?

:cool: :cool:

Flame wars is right bud, that is the most heated topic on the planet! :)

Aftermarket shocks huh? Well, Tamiya has some nice blue ones for the TXT-1, but of course, only available in Japan. Actually, they have a ton of hopups for the TXT-1, THAT YOU CAN ONLY GET IN JAPAN! *** IS UP WITH THAT?!?! (whew, had to get that off my chest)

You can use Losi truck shocks like Jeepinator does, even get them threaded if you so choose. You can use Associated ones as well.

What do I use? I bought a two sets of (four total) GPM Racing overbored 4 inch blue aluminum threared shocks for mine. You have to do the slightest bit of modding on the TXT-1 to get them to fit, but they are SOOOOO smooth. Totaly worth it. :) Downside you ask? $60 a pair. ($120 for the whole truck)

You could probably get a full set of Losi threaded shocks with titanium shafts for around $50 - $70, depending on where you shop.

If you want to see my shocks install on my TXT-1, email me, I'll hook you up with some pics. ( hairball@onemain.com )

Well..........

Here is what you do. http://www.plauder-smilies.de/thinkerg.gif
Canabilize the E-Maxx. Take the Motors, tranny, EVX speed control, drive shafts, and any nuts and bolts you'll be needing. Sell the extra stuff on eBay for scrap. Somebody will buy it.

Then scroll back to the beginning of this thread and check out all my posts (or just email me), and copy my setup for installing all those parts onto your TXT-1.

Then you can be cool like me and have a TXT/Maxx-1 like mine. It doesnt handle quite as well as the E-Maxx does, but its SOOO much more fun. :D :cool:

(feel free to smack me if you think its needed)

[bluesy]

**SMACK** **SMACK**

[bluesy]

***SMACK***

:D :cool: :D :cool:

[Hairball]

OUCH! OUCH! Watch it mofo! :)

So you gona kill your E-Maxx or what? :D

[RCtinkerman]

Hairball if you weren't a male and a Marine I'd kiss you. I am going to look for those shocks this weekend. Usagi probably knows a shop that has them. Thanks:D

OH DUH! You're in Japan aren't you? Geesz, I feel dumb.

You want some pictures of the cool hopups they have out? You can't read anything (its written in Japanese), but you can look at the pretty parts. Email me and I'll send them too you.

doesnt anyone read bios?:confused:
Sure hairballer

[bluesy]

Hairball... hmmmmm. not sure if I have the balls to hack up a running vehicle to mod another running vehicle... with my luck (and limited skill set) I'd probably end up with two non running hacked up trucks... Maybe I'll just stick with the two and stick in some simpler mods... motors, shocks.... etc... I know ... ***chicken***

:cool: :cool:

[RCtinkerman]

Bluesy, just look at both trucks. You've got the manuals. As long as there's no hacking, you should be able to do it. If not, put them back together. Bluesy, you can do it:D

[Hairball]

The only serious hacking will be on raw material, and thats for the tranny mounts (unless you want to wait for Balistic Stupidity to come out with theres).

You'll have to slightly shorten the E-Maxx drive line to fit the TXT-1 with the Maxx tranny, but thats cheap to replace if you want to go back.

And do you want the Maxx tranny shiftable with your transmitter, or just fixed in low gear? (or high gear for that matter) Thats where things get a little complicated.

Let me know what you want to do, and I'll help as much as I can. :)

[Usagi]

Tinker, are we on for sunday?:confused:

[RCtinkerman]

Usagi, most definitely. I want to get the shocks first, then the front skid supports in aluminum and maybe aluminum skids themselves if they have them. I'm looking for a different body as well.;) Plus I want to see how much that Terra Crusher is going to cost me.

[Usagi]

can you get into the chatroom now?

what shock brand i mean?

[RCtinkerman]

If Tamiya has a hop-up shock with aluminum body, I'd probably get that. But, I'd settle for any good Aluminum shock in the right size. I believe Hairball said 4 inches.

[RCtinkerman]

I really love this truck:D

[Usagi]

I think they are out tink, we have to check it out.

[Hairball]

If you decide to use 4" shocks like I did, you'll have to modify your center shock mounts to make them look like this -

http://pweb.jps.net/~hairball/smount.jpg

All you have to do is *hack* off the two outside holes, and use the center ones to mount the shocks.

[Hairball]

Why is it so clean, and new, and well, just plain pretty lookin? :D j/k man, I'm just used to seeing my rig. Its just abused... http://www.clicksmilies.com/sammlung/waffen/waffen090.gif

what are those shocks? gpm? eagle?

GPM, why?

[RCtinkerman]

Thanks Hairball, I got the pics. That looks like an easy fix, I can do that. Thanks again. That pic was taken before it's first real run. Although I cleaned it up afterwards. ;)

[Hairball]

Its a VERY easy fix. You could probably make the modifications with a common nail file if need be. :)

[Usagi]

I thought so HB, they look like their products, we can`t find those gpm shocks out here tinker. You might have to special order. But i think we can find different ones out here.

[Hairball]

The only place I know of that sells GPM shocks is www.hobbyetc.com and they are NOT cheap by any means.

I got mine off of eBay for a much better price.

[Usagi]

I see HB, those parts are cheaply made, but cost alot some of the times.:(

[Hairball]

Isn't CNC Machining wonderful? The Machine cost a butt load of cash, but once everything is setup, you can crank out complex pieces all day like its going out of style. Then you turn around and sell those pieces that cost you $0.02 to make for a small fortune.

2000% Markup sounds about right.

[Usagi]

its nuts a? someday in 30 years I going to buy one and make parts:p And sell them. I be turning chinese :p

[Hairball]

Haha, I've already got an End Mill and a small Lathe back home in Sacramento, but I'm stuck down here in San Diego... ugh.

I really wish I could have those here with me somtimes... Oh the mods I could do to my TXT-1...

[bluesy]

HB... I went to the HObbyetc site and found some shocks (GPM's)..... holy crap... $50-$80US a pair... That's like $150 - $240 CDN a set... guess I won't be getting those... dang and they look sooooooo good too......:mad: :mad: :cool: :cool:

:D

I paid $90 for all four of mine on eBay. It took me three days to talk myself into spending that much on the shocks too. I mean, the stock ones work just fine really.

But they are SOOO worth every penny. :)

If you can afford it, I say buy them... Who cares what it costs, its all about what it means to you. I mean, who pays almost $400 US for a Monster Truck kit anyway? :cool:

[RCtinkerman]

Evidently we do:D It's the love of the hobby. I've got $800+ sunk into a TA04 I don't even drive anymore. And the sad part is I can't bring myself to cannibalize it. :( And that unlimited LRP would sure work wonders in my TXT-1.:p

[Hairball]

Kill it! Steal that LRP for your TXT-1! You know you want to!! :)

I've got two Xpress 4wd sedan cars that I neglect as well. Wish I drove then more, but I just don't really care. I guess I got tired of always tweaking them to be faster.

Now I play with my TXT-1 and my Villain IV (boat) and thats about it for now... :)

I want to get a tank though.

[RCtinkerman]

You know Hairball, I probably should. What the hell, I'll do it tonight when I get home:D I wish there was some way I could beef up the gearbox. I don't have an E-maxx to cannibize:(

[RCtinkerman]

Has anybody done up their 2nd body yet?
:rolleyes:

[Usagi]

$800 only tinker. gee i got about 2000.00 in my pro3:p

heheheh i see a liitle usagi part helping in this picture.. those blue parts:)

[Hairball]

I take it you guys found the Tamiya hop up parts then? :cool: :cool:

[Usagi]

HB, I found those parts the last time for tinker. We are going to met some time this weekend........But its going to rain so i don`t think tinker is going to want to get this chrome dome wet:p :p

[RCtinkerman]

LOL, OH! That's funny Usagi, real funny Hahahahaha:D I'll wear a hat:p HB, those were the only parts Usagi found. By now maybe they have more out. Those were about $25.00 a set you need (2). We'll see what they have this Sunday and let you guys know.

[Usagi]

The main chassy ladder racks might be out........ But nut sure........ More chances then not they might be. But the TC chromy is not very likely :)

[RCtinkerman]

New Era has a lot of hop-ups. Everything I need and then some. So if I can't find em' in Tokyo, I'll order some.

[Usagi]

Tink, can`t you get a metal smith guy to build you some parts?

[RCtinkerman]

If I were still on a ship I could probably get the MR (machine repairman) to do it. They have lathes and all kinds of neat stuff.

[Usagi]

landside don`t you have ability to have them do it for you?

[RCtinkerman]

HB sent me some pics of some really neat hop-ups. The shocks and bumper skids and they were packaged by Japanese.

[Usagi]

tamiya?

[RCtinkerman]

Yes, send me your e-mail, I'll forward it to you. Very interesting.

[Usagi]

in coming..............................

[Hairball]

You guys are doing it again. Using the forum as a chat room.

Why don't you just use email to exchange little notes?

[Usagi]

sorry mommy i told tinker to get a pass he is not do it................

[Hairball]

I give... whatever.

[Usagi]

Hey I seen those pics tinker you sent. I took pics of them!

[Hairball]

Huh? I didn't understand that last post Usagi...

[RCtinkerman]

Get some sleep we have some hunting to do Sunday. Do you think their out yet. I like the shocks.

[RCtinkerman]

HB, Usagi been up all night. It's 0530 here, I have duty, he has gas:D So he's probably delirious by now. You know civilians can't hang with being awake for 24 hours unless their making time-and-a-half :p We're going to try and find those TXT-1 hop-ups and the price of a tank:)

[RCMD]

Wow what a great thread! I've taken a while & read it all through. Now my head's spinning. I just rec'd my TXT! I have a Novak super rooster & will run 2400 packs (only 1 at a time) I was going to get Chameleon 19t motors, but speed gems were recommended. Now that I've read through, I don't want to kill my run times or my tranny. Would Trinity P2k2 be better than stock motors with good run times & safe for the tranny? I've been convinced to order the lower mounts, skid & servo saver from New Era. I have already gotten a hobbico servo with 80 oz-in? of torque.

:) :) :)

[RCtinkerman]

You're doing good. 19T will probably be ok, don't go lower unless you're going to do some tranny changes. I'm running 21T's, 3000 batteries and a Futaba ESC. No heat problems and I'm getting really good run times on the one battery. This truck is really a lot of fun:D

[RCtinkerman]

Wel Usagi and I went looking for the hop-ups for the TXT-1 and found only the cantilevers and blue aluminum shock bodies which I purchased. No sign of the Terra Crusher as yet.:rolleyes:

[RCMD]

Thanks RCtinkerman, I think I'll stick with the 19T Chameleons. Should I wire them in serial or parallel?

[RCtinkerman]

Wire them in parallel. solder + to + and - to -. This will leave you the positive and negative of one motor to connect to your ESC. Works great for long time fun. :D

[Hairball]

Just to clarify transmission busting issues.

To this day, I am the only person I know to blow gears with the stock TXT-1 transmission. I've seen people run 12T doubles WITHOUT tanny problems. Of course everyone I've talked too also ran there modifieed motors off of a Super Roster which supplies the motors with 7.2v. I was running two 19T doubles (Speed Gems) with a Novak/Traxxas EVX (E-Maxx ESC) which gives the motors 14.4v. Trust me, the truck flew! But I also blew up two sets of gears.

Running the motors at 7.2v will keep them tame and under control, and give you truck some much needed horsepower. Just get some good heatsinks on the motors if you want them to last long, and take good care of them (regular comm cutting, brush changes, proper gearing, etc..).

Run them at 14.4v like I did, and you'll have a force to be reckoned with, doing backflips at hit full throttle from a standstill. And able to keep up with buggies and stadium trucks without problems. But expect problems, and at worst, a motor meltdown like I had. :D

[RCtinkerman]

HB, you think metals gears would work any better? It'd be nice to have metal gearbox. I got those shocks you had a pic of :p We also found those new Futaba ESC's. Man they are tiny and expensive, about $110.00. :rolleyes:

[Usagi]

yes, we went yesterday but as i thought no CT. maybe next week or maybe the next.........but not word in sight about its release. I keep you posted.........

[bluesy]

Well guys... After $175(CDN) or so... and about 6 hours work -----> my TXT-1 is fully equipped with bearings. I gave the front and rear axles the spin test and WOWEEEE.... they must have spun for about 26 hours each... of course with the tires on the flywheel effect is considerable... Anyhow the deed is done and bluesy is a happy guy!!!!! Shox are next:cool: :cool:

Metals gears would rule. They'd be SUPER loud, you'd have to grease the crap out of them, probably use a oil filled gearbox (like in real cars), and increse the size of the tranny heatsinks on the outside of the gearbox.

I already talked to a machinest about getting a set or two made. He said 16+ hours a set (all four gears) and a bunch of money.

Its not hard making gears, just the math and the setup time takes FOREVER!

Its a whole load easier to just install an E-Maxx tranny. :) And you don't have to make a complicated shifter like I did, you can just lock the tranny in low and be just fine.

[ProjectTwin]

Hairball,

I blew a Juggy tranny, same thing, just different diameter output shafts. I was using a Modeltech Brushless on 10 cells.

Jason

[RCtinkerman]

Oh well, maybe in the future some company will do it on a limited model. Or better yet find a new material that'll hold up better under a lot more stress for a lot less money. :confused:

[Usagi]

hum thats sounds intersting...........:)

[RCtinkerman]

I thought we agreed to keep this post at the top;) Well I bought the blue aluminum shock bodies but put the piston rods back. Should have kept them, they had the longer rods that I need for the shorter body :( Oh well live and learn:o

[Usagi]

Oh crap they don`t fit!!!!!!!!! RATs!:mad:

[Hairball]

If anyone is curious, this is what it takes to have a working 2 speed transmission, and on-the-fly selectable 4WS.

http://home.jps.net/~hairball/txt1radiotray.jpg

Nice radio tray huh?

Thats almost all the electronics on my TXT-1. There is also a Ko Propo FailSafe unit mounted towards the rear of the truck that you can't see in this picture.

If you wanted to know what all that crap is, just ask.

[TC3 Benjammin]

what is all that crap?

[RCtinkerman]

That is not "crap"! It is electronic RC equipment, the very heart of that elegant truck:D Now Hairball, you may explain. What's all that additional equipment anyway:confused:

[speedydave]

Duuuuuuude...on the fly 4WS... sweet :cool:

[RCtinkerman]

Dang Jeep, where you been? I forgot Hairball can't answer now. He's on his way over here.:D

[Usagi]

going to get anymore optios for this truck? I hearing that those other options will not be out for a couple weeks.

[RCtinkerman]

I'll wait. Everything is going kinda slow, but I can wait. Like the wife says, Christmas already came:rolleyes:

Hey, am I the only one who did up their second body:confused: :eek: :confused:

[Hairball]

I'm baaaaack!!!

Whats up all, and greetings from Okinawa, Japan.

All that extra electronic crap you ask? Well from left to right, solid state electroic R/C switch, made by RAM (can't remember what it stands for right now, goto tower hobbies and serach for RAM 35). Then the other shrick wrapped thingy is a in line servo reverser. And there is also a Ko Propo Fail Safe unit in the rear of the truck as well. I'm going to do a complete "How To" writeup later with a parts list and everything, and I'll post it probably on Jeeps page. Its really simple, and only requires a little bit of soldering. :) (two wires actually).

Now for the bad news.

I'm in Japan, and my TXT-1 is still in California. :( :(

Anyone know of any good Hobby Shops near Camp Kinser or Camp Foster? :) I'm feeling the need to hang out at a hobby shop.... withdrawls........ *twitch* *twitch*

[ProjectTwin]

On the tranny gear issue...I saw in the RCMT TXT forum that delrin gears are being made for the Juggy tranny. Maybe these would work in the TXT tranny as well.

Just a thought...and a *bump* to the top. :)


Jason

[junk4calata]

Hairball, are you talking about a "how to" on how you hooked up your RWS? Interested to find out. If you do, could you please post a link on this thread.

Thanks.

[Hairball]

Already working on it!

The How To write up is about 80% complete, with wiring diagrams and all.

I'll get it up in a few days hopefully.

[Doctor Doug]

I dropped a pair of Trinity Caliber 14-Turn, Double motors into my TXT-1 a few weeks ago. Decent performance considering they only cost about $20 each and come with ball bearings.

[bluesy]

Doctor Doug.... What do you consider "decent performance"? Do you have more noticeable torque, better climbing ability, or were you just after higher speed?:cool: :cool:

[Usagi]

OMG its back!!!!:o :o :o :o :o :o

[Hairball]

Yup, i'm back. Where the heck are you in Japan anyway?

Ok, the writeup is done on how to do the 4WS thing. I just need to get MY computer online so I can upload it to my webpage. (I'm using public acces right now, ewwwww)

[Usagi]

tokyo.........8 years strong. how long you going to be here?

[Doctor Doug]

Bluesy, the 14T Calibers provide about the same performance as the 14T Trinity Speed Gems, but at a lower cost. For backyard bashing I think the Calibers offer decent "bang for the buck" :)

[Hairball]

Only till next February (hopefully). This is my LAST in, and I really don't plan on re-enlisting. (unless the offer me something like $1,000,000+ cash or something) :)

Tokyo is a bit of a jump from me. for I am stuck on this damned island. :) Maybe when I get some leave built up I catch a flight over that way. :D

[RCtinkerman]

Hairball, if find a hobby shop good luck hanging out unless you speak Japanese LOL. Or you might get lucky where the owner speaks English like mine does. Usagi and I are planning a trip to RC show Tamiya going to have, he can tell you more about it.

I picked up some hose clamps from our gas station the other day. I used them to replace the zip ties on the sway bars, makes all the difference in the world, looks better too!:D Got the idea from March RCCA magazine;)

Hairball about your TXT-1, the pay is good here, you'll just have to get a new one:D

[Hairball]

I've already got two! You want me to go out and buy another? Geesz man, you are crazy! :)

When is that hobby show, and where is it? If there is enough time for me to take leave, maybe I can come too. :D

[Hairball]

Ok everyone, here it is, what you've all been waiting for.

Hairball's TXT-1 Project Home Page (http://home.jps.net/~hairball)

Check it out, and lemme know what you all think. (currently only the "Mods" section is up)

[RCtinkerman]

Hairball, I can some up your web page in one word
"OUTSTANDING!" ;) :D :D :D :D

[Usagi]

geeeee........ its nice here i like it. atleast its hot down there! here Brrrrrrrrrrrrrrrrrrrrrrrr:p

[junk4calata]

Hairball, that is the first time i've seen such a thing - on demand 4WS. Nice work. BTW, how did you ever come up with that idea? Its just of of those things like "it's so simple, why didn't anyone think of it before".

[bluesy]

Usagi... who gives a whit about the weather in your area? NO-ONE!!!!! Please keep your comments to the topic. You have consistently used this thread as your own personal message center. I for one, am sick and tired of your useless comments.

Hairball has just finished an extremely important web page for those of us who actually own and drive a TXT-1.

Hairball.... superb work. Like I posted on "the other
'uncensored'" BB..... very informative. Thanks for all your effort and creativity.... :cool: :cool:

[Usagi]

OMG I am so sorry king! I did not know you owned this place? FOR you info i have post info about this truck. so please don`t be so rude.

[Fetztang]

for those of u in japan how much is the txt-1 there? my brother who is stationed in korea went to a hobbie shop and they said that they could get what ever he wants ordered from the states. so the price would be the same:(


for those of u arguing its not like we need any of that crap here. nobody is any bodies boss so take it some where else

[Usagi]

prices are are about 24,500 yen for the txt.

[bluesy]

Usagi.... I am not a king.... and I never suggested that I either own or control this thread. I merely stated that I didn't care what the weather was where you lived and that you consistantly post off topic. I went through the entire thread and counted......

here are the results...

posts about the TXT-1 ..... 7 .. including 4 regarding cost only!
posts about the Terra Crusher... 2 ..
posts not on topic or other time/space waste.... 20!!!!

gamesetmatch....

BTW ... do you even own a TXT-1????

First off, a big "thank you" to eveyone and your kind words about my little corner of the web. :)

How did I come up with the 4WS idea? Well, when i first got the idea I found somone talking about using a JR-R1 and its channel mixing on a Jugg 2 to accomplish the same thing. I didn't have a R-1 at the time (I do now) and I wasn't sure about it, because my third channel was already being used for my E-maxx Tranny.

The a guy emailed me about my rig and had questions about what radiot to use with his soon-to-be-bought TXT-1, and I went into my usual 4 page essay about why this radio is cool, and why this one isnt, blah blah blah... They he asked if there was a way to turn off the rear servo WITHOUT channel mixing. Hmmmm, that got the wheels turning in my head. I came up with a complex mechanical setup using a simple electronic switch hook up to a servo to literaly cut-off the rear servo. Simple enough i thought. Then he said "why not use a relay?" DUH! So I went to work on this idea. But then while watching the TV, and hold my TXT-1 with the power switch off, I learned an important fact. With no power, servos DO NOT hold there position. Hmmm.

Off to the internet I went to learn all I could about hows servos work and why they work, blah blah blah....

This is where I became one with the servo.

So I needed a way to keep the servo "powered up" and something to give the correct voltage pulse to tell it to hold its poistion. DUH!!!! FAIL SAFE BABY! Off to the hobby shop i went to buy all the parts (servo, fail safe, etc..) to test the idea. All I did want plug everything in (I didn't have the RAM 35 yet) and simply unhook the white wire while everything was on to see if it worked. IT WORKS!!

Then I went back to the relay idea, and I just knew that it wasnt going to work the way I wanted it too. Then I started diging around the net for a solid state (no moving parts) switch for R/C use. After about an hour of digging, I cam across the RAM 35, jumped onto towerhobbies.com and order me one.

About a week later i had it all wired up, tested it, and eveything work perfectly. Then, about two days later, I packed my bags and shipped off to Japan. Funny how these things work out, ins't it. Now my TXT-1 sits back home in California with my wife.

I want her to ship it out here, but its so much more than the truck. The batterys, the radios, the tool boxes, the spare parts.... etc...

I'm just trying to figure out where to store all this crap here in my small baracks room. :)

Anyway, I hope that sums things up a bit. Please feel free to attempt your own 4WS mod. But if you fry you truck, its on you. :)

[Usagi]

Again I am sorry Blue. I try to keep it to the subject from now on. If you want to kow any info here about options and or other makers parts I can see if i can help you out.

[bluesy]

Usagi... everything is cool.... :cool: :cool:

Right now I'm toying with the idea of a three way switch, so one way, the rear servo is off, next the servo is on providing rear wheel steering, and the NEXT would provide wheel rear steering with the rear servo NOT reversed, so you could get the crab walking effect. More for show than anything, but it could be cool. :)

[junk4calata]

And the wheels just keep on turning. That's why they say "Its NEVER done"

[RCtinkerman]

HB, your ideas although maybe not new, are certainly the first actually put into practice that I have heard of. Ever think of maybe a patent before you just put it out. IMO you should keep the diagrams off public access until you check into it more. Engineers get paid well for such innovations.:confused:

[Hairball]

RCTink -

I didn't really invent anything, I just used existing electronics in a new way.

I like the thought though, but I believe cool things should be free, and not kept secert from the rest of the world. :)

Oh, and I updated the crap out of my page, making the 4WS section easier to understand.

[RCtinkerman]

You're a good man HB. Up early I see:D

[Hairball]

I'm a Marine, I'm always up early. :)

[RCtinkerman]

Hairball as you have proven to us all, there is so much that can be done with the TXT-1. All we need now is for Tamiya and the after market companies to pour on the hop-ups! :D :D :D

[Hairball]

Who needs aftermarket stuff when you can just do what I did and make your own? :)

Ok, there is a few things that I bought, but only because I didn't feel like taking the time to machine the peices myself (New Era Aluminum Lower Supports)

Just use whats already out there, and adapt it to fit the TXT-1. Its more fun that way. Plus, you'll have a truelly unique peice of R/C equipment, unlike those damn E/T-Maxx guys who all buy the same aluminum stuff for theres, so they can be just like everyone else.

If you haven't noticed, I beginning to build up a truely unique dislike for the Maxx line of vehicles... hehehe

[ProjectTwin]

unlike those damn E/T-Maxx guys who all buy the same aluminum stuff for theres, so they can be just like everyone else

I was lucky enough to get a TXT before most of you in the states. When I posted my TXT with Maxx tranny, many people started following suit. Soon there will be many more people doing the same things with their TXTs, not just tranny or Maxx driveshaft mods. The T and E-Maxx have been out a while and you can build an entire truck without buying a part from Traxxas. I wouldn't develop a dislike for a vehicle based on aftermarket support or the fact that many people seem to like the same modifications or upgrades on their truck.

Without straying too far from the topic, as time progresses, you'll see that soon many people will be performing the same basic mods to their TXTs. They won't be doing this to "be like everyone else", but because the mods have been proven by everyone else to be effective and work.

When everyone is performing the same tranny mod I did to my TXT within the first 24 hours of owning it, you won't see me develop a hate for the TXT , even if TXT owners are all doing basically the same thing. It's part of the hobby. What works, and is proven to work, will be used by many.

Jason

[Fetztang]

how much is 24,500 yen in us dollars?
hey jason how much was your txt-1 i know u got it in korea and every time i try to get an answer you seem to stop talking on the
thread for a while

[Hairball]

Well, today's YEN to US dollar rate is 1 US - 134 YEN, thank you www.xe.com

so thats about $182 US for 24,500 Yen

pretty cheap huh? :)

Oh, I only installed a E-maxx tranny in my TXT-1 because it seemed like my only option at the time. The kept blowing stock trannys, and the Maxx tranny seemed so much stronger. :)

Honestly I really didnt want to, but I'm happy with it never the less.

[ProjectTwin]

Fetztang, I honestly dont' remember, I believe it was 2-something. The LHS here usually gives me a pretty cool discount.

I remember it was 300,000 won or so.

You can get a TXT from RCParts Hong Kong for 260.

http://www.rcpartshkg.com/

Jason

[RCtinkerman]

Hopefully I will never blow my tranny, but if I do my only option is to adapt an E-Maxx one to my TXT. That's unsat, the after market parts should be out there for those of us who can't mill or make our own. Tamiya should first and formost support their own product. I with agree HB in the fact that I might want something different, but I also agree with Projectwin that the support for a product, that works, should be out there and availuable.

[Fetztang]

wow that is really sweet i hope my broter can get to japan or wherever yen are used and get me a txt-1 man that will be the best:D he checked out a korean hobby shop and they said they would order stuff from the us so he is going to have to find a diferent shop:p man i hope i can get one for that cheap then i could have a maxx tranny and have the two speed

Hi tink, hows your truck running.........

[RCtinkerman]

It's running great! As a matter of fact Mark and couple other of my friends will go out and run the cars and trucks tomorrow:D
I'll get to see how well those hose clamps work.

[Hairball]

RCTink-

What are you running in your TXT-1? Motors, ESC, Batterys, etc..

[Usagi]

Great newds! Those txt-1 shocks will be arriving in shops in Japan some time in the middle of march maybe 12th or 13th. From my source.:)

[Hairball]

I thought they were already out :confused: :confused: :confused: :confused:

[ProjectTwin]

Geez....501 posts in this thead...:)

what? from in japan? hum.......i have not seen them no! march 19th! those shocks will be released! where you getting your info from?

[Hairball]

Didn't RCtink already pick up a set?? :confused:

[Usagi]

they did not fit.....the were to short.

[RCtinkerman]

OK, I bought the shock bodies, they were packaged separately from the rods. I assumed the rods on the stock shocks would work but they were too short as the new blue aluminum shock bodies are somewhat shorter.

Now, what I'm running in the TXT-1

Tranmitter- Futaba 3PJFS
Radio- Futaba PCM 1024
ESC- Futaba MC330cr
Motors- RUSH 21's
Battery- Team ORION V-Max 3000's (I have 4)

I haven't put the LRP F1 PRO reverse ESC in yet, too lazy I guess.
I should pick up the rods this weekend or next.

[junk4calata]

RCTinkerman, how you wire up the Futaba ESC? Are you running both motors?

[RCtinkerman]

Yes, I'm running both motors. Wire the motors in parallel. Solder the plus and negative of one motor to the plus and negative of the other, now you have one set of connectors for the ESC.:D

[Hairball]

RCTink- You should have just got the GPM shocks! :D

Can you get the rods that are supposed to go with those?? Or do you have a worthless set of shock bodies now?

[Usagi]

Those GPM are only in the usa.he could import them

[Usagi]

Blue I am still waiting for a I am sorry.......:rolleyes:

[RCtinkerman]

Yes, I can get the rods. I had them in my hand:(

[Usagi]

Tink,going back to the shop so time in a few weeks?

[speedydave]

How durable are these things? Also, anyone with an E-Maxx tranny in their TXT-1, how do they run compared to the stock tranny? thanks.

[Mason Copeland]

Great pics guys!!

[RCtinkerman]

SpeedyDave, read through the whole thread. Hairball has done that and more to this truck, you won't believe it! :D Yes, the truck is durable too!

[Usagi]

Tink, went to the shops yesterday no sign of those options yet just as I said. another week or so.........

[RCtinkerman]

I'm aiming for next Sat or Sunday.

[Usagi]

There is noway that those options will be ready buy then tink.

[speedydave]

Tinkerman, what do you expect? I'm lazy, I don't want to read 13 pages, lol...Fine, I'll get started...

[JeffHo830]

Hi, just started getting interested in the hobbies again. But been crazy on model kits since I was a kid. But since didn't have a lot of time and money, so only been building those mini 4WD and static kits on and off for the past 15 years (27 now). The TXT-1 will be my 1st real R/C model kit (not counting the Tyco R/C truck I have ^_^) and probably the only kit I can afford for a long time.

I had been reading the whole thread. Pretty much kinda gathering information on getting the "RIGHT" parts to start instead of going back to change it. This thread gives a lot of informations. But also a little too much to decide for me. I plan on using my TXT-1 just for rock climbing but do want a little speed. Not insane speed like Hairball, but faster than the general consense of the "slow" speed of the stock TXT-1. Can anyone recommand me on a budget but a little faster motor that will works with the stock TXT-1 without killing the internal gears/parts of the truck? Also I plan to run 2 battery to maximize the play time on the truck. Does the recommanded motors works well with 2 batteries? I heard that you can parallel the batteries and it'll works with the stock TXT-1 setup, is this truth? If so, how can I do it?

Here is what I plan to get with the TXT-1 kit:
-Hitec 645MG Hi-Torq Servo
-Novak EVX ESC (some one said it's cheaper than SR ESC)
-Kimbrough Servo Saver
-Juggernaut Bearing Set from Tower Hobby
-Center Skid Plate

I have some more question also. Do I need the Traxxas half shafts and diff output? I want a good suspension movement and someone suggest this will helps. What is the rod end suspension links thing I read on some of the post? There is also a cantilever aluminum set in Tower Hobby, isn't the stock one aluminum? Is the cantilever push rod the same as I ask in the previous question? Also might be getting the lower support and the bumper support and bumper from New Era.

Last question is for Hairball. I'm planning to do the 4WS on the fly setup as you. (Going to read your website as soon as I'm done writing). Should I get a second Hitec 645MG for the 4WD? Or just any regular servo will do.

As you can probably guess, I'm trying to build a strong truck (aluminum parts) and some rock climbing and a little bit more than a walking speed. Please feel free to give any advice. Since as you can tell, I'm as "stock" as a newbie can be, pretty much clueless. :D Thanks for any helps in advance.

Jeff

[bluesy]

Let me be the first to congratulate you on your choice..... and welcome to the best BB on the web!!!! I have a TXT-1 that is pretty much stock (except for ball bearings) and I'm happy with the overall performance. It certainly doesn't 'fly away' from you but with the stock motor and 2400's I get 15 to 20 mins of 'play'. I mainly rock crawl with it as I live where there are huge narly rock gardens that I can get at. This is were this beast really shines. I have an E-Maxx that I wish I had never spent the money on and got another TXT-1.... so that I could do what the others have done and gone the 'insane speed' route.

Anyhow... I won't even try to tell you how to hop up your new beast as there are others who can do it better.... just welcome and enjoy the "BEST" TRUEST" Monster truck you can get.

:cool: :cool:

PS... I haven't tried the dual/parallel battery yet but that's about the only real mod I'm gonna make..... then maybe I can get around half an hour of run time.... wow

[Hairball]

Ok, I'll try and cover everything here. (ugh, too many questions all at once :) )

On the fly 4WD steering. Read my webpage, and use the same servos that I did if you can afford them ($100 a pop, but well worth it).

The reason for digital is the holding power of them. Jeepinator (you listening bud?) can explain this better than I, but just take my word for it. They rule.

If you don't want INSANE speed, stay away from the Traxxas / Novak EVX. This thing is great, but it will over power mod motors until the smoke. Fun, but gets expensive after time. :)

I think the TXT-1 and the Juggernuat 2 use one or two different bearings, so you may want to check this before you buy it. If worst comes to worse, you'll just have to purchase one or two seperatly along with the kit. Most will work.

As for motors. If you get a Novak Super Roster (I almost wish I had bought one) you can run some mild mod motors without any hassles. Like 19T would be fine.

The Traxxas half shafts rule, but are not needed. The best thing about them is the screw goes *through* the tranny outputs, so there is NO WAY that the half shaft can split off the output shaft.

Aluminum for durability? Check out New Era Models lower supports. A bit expensive, but you'll NEVER break them. (If you do, I want to see pictures!!!)

The stock catalevers are plastic, but they'll never break, and work just fine. The Aluminum ones are mostly for show.

Two packs with the stock speed control? Sure, it would work, but I highly recommend it. MSC (mechanical speed control) are just plain lame. They are good to use if you like to have your model run out of control. If you like your model under control, spend the money and get a good ESC.

Center skid? I bought the Balistic Stupidity one, and it fits PERFECT. And, if you go nutzo like me and install an E-Maxx tranny, your find that the skid plate still fits one just fine.

Did I miss anything?

[Hairball]

WHAT?!?! No on the fly 4WS?? You're kidding right?

Tell you what, if its that big of a deal, you buy the parts, send them to me, and I'll wire em up for you. :)

It'll be a true Hairball work of art, just like mine. :D

[JeffHo830]

Thanks for the welcome Bluesy and the infos Hairball. Since I can't get everything all at once. I'll have to get the parts bits by bits. I'm going to get the kit last so I won't build the kit without all the parts I need. So getting the right parts is important since I don't have the truck here with me to test it out. Here is the updated parts list:

-HiTec 925MG Hi-Torq Servo for front and back.
-parts for on-the-fly 4WS
-Super Rooster ESC
-Center Skid Plate
-Aluminum lower supports
-Aluminum bumper supports and bumpers
-Kimbrough servo saver
-Bearing set (probably get them seperately)
-parallel setup for battery
-Nissan Truck body if I can find one

Oh Hairball, can you recommand an upgrade motor that will work with the SR ESC that will not hurt the gearing/internal parts like the stock motors but a little bit faster? Also do I need 2 servo savers since I'll have 2 servos now? Thanks for the helps. Now I can start ordering parts. :D :D

Jeff

[draggerman11]

First off, welcome to the hobby Jeff!

The standard R/C voltage used in 1/10 scale is 7.2 volts. The EVX esc is made for another truck that requires higher voltages, 14.4 volts. If you were to buy this esc, you would need to also use the motors specifically made for it. But, they can reak havoc on the tranny gears.

I would really go with the Novak Super Rooster. You will be able to use regular motors, and will also be able to wire 2 battery packs in parrallel for double the run time, if you like(This cannot be done with the EVX).

A good pair of motors for what you will be doing is the Trinity Speed Gems Sapphire. They will give you more speed, and the same, if not more torque. Also, they will be fine on your tranny gears, and will not deplete run time too much.

Basically, any motor will work with the 2 battery packs in parellel. When the packs are in parallel, they give the same voltage as one pack, but double the miliamps. So, you will gain no more speed, or power, but will gain more run time.

Have fun!
Kyle:)

Correct, I use the white Kimbrough servo savers at both ends. I suspect the 1/8 scale BLACK servo savers would be better, my LHS didn't have any when I got mine.. hehe

Trinity Speed Gems 19T (can't remember the name)

Peak also makes so higher turn mod motors, 20T and up I think. goto Tower Hobbies and search them out.

Not ture.

You can run standard motors on 7.2 volts, you just have to maintain them often (cut the comm more often, and use HEAT SINKS!)

If you don't have a lathe, well, you're S.O.L. :D

They will get REALLY HOT, but they SCREAM, and the truck will be a rocket on wheels (I used two 19T double s with standard gearing). But, if you read my web page, you'll also see that I kill one of the motors as well. :rolleyes:

[draggerman11]

Hairball, I am aware that you can run them on 14.4 volts. But, as you stated, they wear FAST. Or, as in your case, just melt!:p

It is really better to use the regular motors on the 7.2 volts.

[Usagi]

I am going to get one of these for my sisters boy for his birthday this year.

[JeffHo830]

Hi guys, I was just at Tower Hobbies to check out the hi torque servo. There are 2 version of the 925MG. The price different is about $5. What are the different on those 2 servos? Also the 945MG and 925MG are the save price. Hey Hairball, what makes you choose the 925MG over teh 945MG? Or anyone can jump on this. Thanks.

Hey All,
I did a few runs on mine stock...there is something about this truck my girlfriend doesn't understand, which is why I want it to go faster and why I love it so much!!! She doesn't even know about the $$$ which is pretty crazy, but who cares theres worse things you can do with money right!!! anyway to get back on the topic here...I have a Super Rooster and 2 17turn single speed gems on order, should be here by the weekend...question is can I run 12 cells and these motors both in a parallel circuit and keep the rooster and the gears happy...I am also working on cutting a skid plate out of 1/16 stainless and when I get the motors will cut some custom heat sinks out of aluminum to fit in the chassis, I do it all on a cnc wire EDM, thats my job...gotta have a little fun with it!!!
Thanks,
Murf

Hi, more newbie question here. :) I was looking at the parts list I created for myself. It seems the the for the truck of my dream is getting longer by days, and it's also getting more expensive. I read here that someone got the alumnium lower support from New Era. But from the picture on the Tamiya website and some of the stock photo I saw. It seems the stock lower support is metal. Is it chrome plated or it's just weak metal for the stock lower support. Also, I found the alumnium cantilever too, but when I look at the truck, it seems the whole system is in some sort of metal. But I remember Hairball said it's plastic. Where is this part located on the truck? Last question so far, what is the different between the new era alumnium steering rod and the stock steering rod? The stock steering rod seems to be metal too. Are the stock one just weak metal? Thanks for answering all the question.

Jeff

P.S.: By the way, I can't get Hairball website to come up. Is it down? I'm making a parts list and need the components (and procedure later) on the on-the-fly 4WS (TM: Hairball). :D :D A little trademark for Hairball.

[bluesy]

Jeff.... Hairball's site is no more. He posted earlier on (which has been deleted) that someone had angered him while he was trying to explain some of his mods. So he took the site down. It is a great loss to all of us here who appreciated his work. I can't blame him though when his efforts were not appreciated and even derided.

To your questions

The stock lower support is grey plastic. If that is the one that holds the steering servo. For me and what I use the TXT-1 for it is plenty tough. The cantilever arm - the right angled arm between the upright rod and the shock is also grey plastic. Again tough enough. I think (my opinion only) the aluminium one is eye-candy. All of the steering rods are metal but only threaded on the ends. To adjust them you need to undo the ballcups. They aren't turnbuckles. For me, once set to the right length, that's it. So no real need for turnbuckles. the manual has the lengths for these rods and they worked out just fine for me.

I hope I have been able to be of some minor assistance.

BTW.... I would like to extend my apology to all TXT-1 lovers for my actions earlier which have resulted in some posts being deleted. It was immature and meaningless. It won't happen again...

[Hairball]

What did I miss after I said that I took down my website?

[JeffHo830]

Thanks bluesy, that helps a lot. At least I can hold off on those parts later when I save up some more money for the truck. Right now I think I'm going to just get:

-the center skid plate,
-the aluminum bumpers and the bumpers supports (for crash protection),
-the Novak SR ESC,
-HiTec 925GM servo
-Kimbrough servo saver,
-Trinity Speed Gem Sapphire 17T
-Tire Foam

How does this look? Any comments is welcome. Does this seems like a pretty good speedier setup than the stock and a little bit more tougher climber? I'm still deciding on radio gear. I have some more questions tho. I plan on putting a set of headlight and brake light on the truck and using the radio control to turn the light on and off. I'm also hoping to get the on-the-fly 4WS to work. Do I need a 4 channel radio control? Any recommandation. Also does the radio control usually comes with receiver? If not, what is a good one to get? Hey Hairball, is there any chance that you will put the 4WS information and setup again? If not, can I email you for the parts and setup procedure? Last question so far. How good does the TXT-1 do with water? Maybe like half a tire to 3/4 of the tire height water? Better question, how high can the water be before the TXT-1 is in trouble? Thanks for reading so far. Sorry for so many newbie questions.

Jeff

[bluesy]

Jeff.....

Your shopping list looks pretty good. the only thing on there that I haven't done is put foams in the tires. In the manual Tamiya says not to glue the tires to the rims (something about a bit of shock absorption on the drivetrain.) I glued mine and the difference is amazing. I drilled a few holes in the wheels before I glued the tires on and this seems to work great for rock crawling. The tires kinda distort when its crawling around and gives pretty decent traction. I've taken it more places that my E-Maxx runs away from....

As for lighting up your truck and 4 wheel on the fly steering...can't help you there but I'm sure there is someone who will pipe up .......... yooooohoooooo .... is Hairball there???????????

Just remember, Jeff, we all started out as newbies and the only dumb question is the one not asked.... fire away.... and have fun....


BTW.... Hairball ... I'll e-mail you with the shenanigans that went on after you posted the demise of the BEST TXT-1 website around...... *snicker*

:cool: :D :cool:

[RCtinkerman]

You missed them completely deleting my response. Anyway, I'll say part of it again. I am not alone when I say myself as well as many others on this board appreciates your sharing the true versatility of the TXT-1 with us. I hope you can again resume sharing your ideas and modifications with us. But, remember what I told you about your innovations, you have a talent, don't waste it!;)

[bluesy]

Beautiful day here... bright and sunny... about 55'F.......

Guess what I did...

[RCtinkerman]

:cool:

[Usagi]

As always i will be willing to give as much data about the txt-1 and other option part related info as before......... To all people that were not involved I as sorry that you had to see the ugyness that happened.. Lets have repect for each other. Tink I heard that the chassy parts should be ready some time in april late or may.

[Usagi]

sorry jeep but you been on my ignore button for over 3 months now. even before you were a mod........ It is all over now jeep don`t sart it up again. all is happy........

Well Jeep, I have to admit that your was the first, and some very good information came out of your page. Mine just had some groovy technical stuff.

If you want, maybe we can combine the two, and have the ultimate online TXT-1 resource.

What do you think?

Or maybe I should just keep my toys for myself... hmmm...

[Doctor Doug]

Dr. Doug's TXT-1 FAQ site has been up since the first day the TXT was released in the USA. There is plenty of information for new TXT owners to look at on this site. And, hey, I even have a link to Jeep's page on there :D

[Doctor Doug]

Bluesy, nice area you run your truck in. The next time I am visiting my brother in Vancouver I'll have to bring my truck and head over to the island.

[JeffHo830]

Hmmm.... Hairball, it would be cool if you and Dr Doug can combine the information on one site. Dr Doug has a lot of details on the TXT-1. And Hairball had a lot of technical procedures on the TXT-1. It would be beneficial to new TXT-1 newbie. Hairball, I was looking at the parts on the on-the-fly 4WS on Tower. The RAM35 you mentioned is the "RAM simple R/C switch" right? Also the only failsafe I can find on Tower is from Futaba. But it's has a casing as oppose the cheaper one that has the electronic expose. Is the Futaba one ok? I didn't remember which one you picked for you setup. Only read your procedure once and only remember the schematic, parts and a little wiring procedure. :p
My head was kinda spinning last night, is there a some kind of speed sensor for R/C in general? I was thinking maybe take Hairball design to the next step and make a speed sensative 4WS. Low speed=fully engage 4WS, high speed=no 4WS and medium speed=partial 4WS. You think it'll work? Man, I didn't even have the truck yet and I'm already thinking about these stuffs already. What gonna happen when I get the truck. ::shudder:: :D :D

Oh can someone answer the different version of 925MG I saw on Tower? It's $5 different, which one should I get?

Jeff

[TXTTHIS]

i'm planning on order a kit to nite. but here is the deal. for a guy on a budget what esc, battery, motors should i get?????? single bat. ( :confused:

[junk4calata]

Jeff, Sorry to bust your bubble, but you said at the beginning of your posts that you are on a tight budget. I have a recommendation for you that I am sure pretty much all others would pretty much agree on. Just buy the truck first ( as opposed to the parts like you stated ) and run it stock. While it might not have 4WS, be fast, or have an ESC, It will be there for you to play with and quite honestly, until the truck has been modded by others, all agreed that it was ( and still is ) one of the best trucks around.

The stock motors will give you about 15-20 minutes of run time per pack and if you run 2 packs in parallel, you should about double that time.

As for the speed of the truck, I think you will be better off getting used to how the truck handles first before you start adding things on - If you added speed and 4WS, if you have no previous practice with the truck you will pretty much be upside down when you make turns.

As for the stock MSC, its fine for the stock motors and as long as you have a decent FM radio, you don't really have to worry that much about run aways. Besides, if you add up the price of the Novak ESC and the motors you want you are looking at about $150 or more and thats about half the price of the truck.

And if your really tight on a bugjet, there is a guy on eBay by the name of HK_Cowboy that could sell you the truck for $250 plus $45 shipping via ground. That comes to $300 delivered as opposed to about $350-$380 from stores plus tax if you buy it locally or extra shipping if you go online. Just a thought if you want to save more money.

The main reason I am recommending that you buy the truck first instead of the parts ( like I did and just admired "parts" for months before getting the truck ) is because that way you can have fun with it. And who knows, depending on your creativity level, you might even come up with a better way to do a certain mod or even come up with a new type of mod. You will definitly see things differently when you have the truck in your hands.

The only thing I recommend that you don't go cheap on is steering servos, batteries ( I have Panasonics 3000niHM - not cheap but very good punch and run times compared to others) and a charger ( never saw that in your shopping list and you can't run your truck with out one - BTW, stay away from the 959 superbrain, that thing overheats like crazy and even blew up on me with dual cooling fans installed with the top cover case removed ).

Other than my long post have fun.

[draggerman11]

TXTTHIS, I merged your post into the TXT-1 thread, because that is where it belongs. Next time, post it in this thread, or the Monster Truck Forum.

Also, read the Vehicles Forum Rules at the top of the Forum.

Thanks,

[Hairball]

Speed sensor? Already thought of that, but I have no idea how to accomplish it. Maybe using some kind of currect sersor on the motors wires.. but we'd have to build it ourselves, and since my father passed away a few years back, my on call electrical engineer is permanantly off duty. :( Life just sucks sometimes.

Thats how I know all this crap I do, he taught me sooo much about electronics. And engineering, and metal work, etc.. hehe

Anyway. As for the fail safe, I used a KO PROPO unit, and I think its the best way to go. I havent looked at the other brands too hard, but I wasnt impressed with what I saw.

Oh, and as for buying the truck first, DO IT! Play with it first, and then see where you want to go with it.

I've got about $1600+ in mine, and thats NOT including batterys or charges. (does include the radio though)

Oh ya, RAM 35 - Yup. I think they make some other switches that could work even better, but I just found the frist one that would work, and bought it. I was on a pretty tight time table, and wanted to get it done before I shipped off to Japan. I ended up getting the RAM35 in the mail about 3 days before I flew out. SO I had a total of 2 days to play with it. :(

Now it sits in storage. Grrrrrrrrrrr.....

[JeffHo830]

Hi, thanks for the advices junk4calata. I'll probably going to upgrade the truck to aluminum parts later, after seeing how strong are the parts 1st. The parts (radios, servos, and whatever I have on the shopping list) I want comes out to be about the same price as the truck. So it's the trunk or the parts. But I think I'll get the parts 1st. Since I got the Kyosho 1/8 R/C motorcycle not too long ago and haven't start on it. I'm pretty much going to make the motorcycle static display(love the chain driven system), since I don't feel comfortable running a 2 wheel r/c. (might change my mind later tho.) I'm just deciding on what color to paint it and which parts to paint. So I have my hands full. Even if I get the kit now, it'll just have to wait until I'm done with the motorcycle.

Hairball, interesting idea on the current sensor. I guess I'll do some research when I have time. It's funny most of my thinking is done when I'm in the shower. :D :D :D

Jeff

[junk4calata]

Hi HB, it's Nick ( originally emailed you about the on demand 4WS )

Correction. You do not need a current sensor, you need a voltage sensor as the ESC supplies various voltage to the motors and that determines how fast the motor turns ( Yes I know current - amps - has something to do with it but it is the voltage that determines motor speed ).

Anyway, Since I know I love relays and after plenty of experimentation I have learned a lot about them. What you could do in this situation is install a relay ( to replace your ram 35 or wire it in parallel to yoru ram35 to have dual type controls ) that is actually higher in voltage than what you want. Not sure how to explain it right but I will give you an example. A 12VDC relay will latch at anywhere from 7.5 volts to past 12 volts but not below that voltage. Since most 7.2v packs actually put out over 7.2 volts, in this case this relay will only latch at full throttle. If you install the relay to avtivate your fail safe, then you know the rest of what would happen.

The other thing you could do is experiment with a rheaostat ( variable resistor ) and use a relgular 7-9 volt relay. You controll the rheostat and adjust it for what ever voltage you want the relay to see and what what throttle position ( again, what voltage goes to the motor ) If you need a quick diagram e-mail me and i'll send it to you ( but then again your in Japan w/no truck) :( :( :( :(

[Hairball]

I do my thinking when I'm reading this forum. Somone will say something, and my mind just starts going a hundred miles an hour. Kinda sucks actually, because I can't turn the damn thing off. :)

Some where out there I saw a device to slow a servo down. I'll try and find a link to it. it was adjustable, but I think only by a poteniometer, so you've have to probably wire in some logic circuits to only enable the "servo slow down" device while your at "X" point in the trottle throw.

X = fixed point you determine.

I guess you could wire in a "Y" harness to the throttle where one end goes to the ESC, and the other goes to a servo that is mechanically attached to the adjustment on the "servo slow down" device, so the the servo would slow infinetly with the trottle speeds. This would have to work in conjuction with my 4WS switcher (at least the way I'm figureing it out in my head right now... :) ).

Here is the real kicker. WHERE ARE YOU GOING TO MOUNT THIS STUFF!?? You've seen my radio trany, and that thing is FULL. Well, I could move the 2 speed shifter servo to the rear of the truck, I just didn't have time to make a bracket. When I get home, I'll tackle that. That could make room to mount another servo on the truck to adjust the "servo slow down" device.

Ugh. What the heck are you getting me into Jeff? :D

Now, if I've totally lost you, i'll try and break it down a little simpler. (if I can, I need to draw a schematic to make sure the logic is correct)

[Hairball]

Hello Nick, how ya been? Get your truck yet?

Ok, this is what I get out of this.

NEGATIVE GHOST RIDER! :D

The servo needs full voltage at all times to make the thing work properly.

The device I mentioned (still looking for it) will "digitally" slow down a servo over the signal wire, while the servo still gets full voltage, and full holding power. The digital servos were meant to work at a specific voltage, and running them at a lower voltage would be bad for the electronics in my opinion.

Now, as you said, I've got no truck to test this out right now, so I'm just playing with theroy in my head, so could have something all crossed up in there. :)

And correction to my last post, a servo speed adjuster is not needed, a servo endpoint (stand alone from the trasmitter) adjuster is needed. This way, the servo would only turn so far at high speeds, and have full movment at low speeds.

Now we just have to make it work.

[Hairball]

The on/off ratio determines power output of the motor. This is also what causes the motor to squeal (and creates the noise in digitial servos too). Just so you know :)

Thats probably why I came up with "Y" harness / second servo idea instead of going with the current sensor. I didn't realize it at the time, but now it all makes sense.

Thanks Jeep. You da man. :D

[junk4calata]

HB,

No truck yet hopefully in about 2 weeks after I sell my t/e-maxx ( T-maxx chassis with e-maxx tranny ) to a guy at work who wants it and is waiting for his tax refund check.

As for the other posts I was under the impression that you wanted a automatically controlled on/off RWS depending on your speed. What is it that you really want to accomplish then? Something similar to a dual rate steering while having all the time RWS? Please attemp to unconfuse me .... hehe.

Jeep,

Its funny you disagree with me cause from what i've seen ( tested on my own ) the more voltage a motor gets, the faster it will spin. Hook up a voltmeter to the engine and take voltage readings while slowly applying throttle and you should see the voltage increase - I did. Also, If you state that the ESC "switches" voltage on/off, then how do you explain MSCs and drag cars that have a micro switch to close a circuit powered directly from the battery to the motor. You might be right that it "switches", but I know from experience that voltage also increases.

[draggerman11]

Junk, an MSC works by burning off some of the electricity through its resistors, depending on how much throttle you give.

A Micro Switch is just that, a switch. You press the button, and all of the electricity goes to the motor.

An esc does work by turning the motor off and on very fast, depending on how much throttle input you give.

[junk4calata]

but would you agree that the voltage to the motor varies?

[junk4calata]

On AC? Why, aren't they powered by DC? an MSC pumps out voltage in DC not AC.

Besides, If I remember correctly, AC motors are slow to spool up while DC are almost unnoticable and those motors reach peak rpm pretty darn quick. Will try meter on DC and AC and see what happens.

[junk4calata]

Ok, here are my findings ( test on a Tamiya TL01 chassis, Towerhobbies Speed Secret motor, with Futaba MC330CR ESC, and Panasonic 3000 niHM battery 6 cell )

With meter on AC mode, motor started moving and meter displayed 1.32VAC stablized. At max RPM - throttle - meter displayed 0.161VAC.

Now with meter on DC mode, motor started moving and meter displayed 0.403VDC stablized. At max RPM - throttle - meter displayed 6.670VDC.

If anyone else would like to try it, be my guest. But based on my experiment with meter on both setting, I can conclude that the motor spins faster with the more DC voltage it gets ( which would also explain how guys that run 7-10 cells are even faster and faster on the same motors )

[Hairball]

Does it really matter that much?

And even before we decide on this, don't we have to BUILD the circuit first anyway?

geesz guys, you need to calm down a bit.

[Hairball]

Here comes my next mission, and I have no idea how I'm going to pull it off.

On-the-fly selectable sway bars! I know it sound nuts, but it would be WAY cool. Anyone have ANY idea how to accomplish this? I was toying with a few ideas, and they all went south.

I need some fresh material. :)

Oh, and mud rules! I love the stuff. You know what even more fun Jeep? Small streams! Just waterproof your electronics, and blast away. Traction becomes a bit of a problem though.

[junk4calata]

Now That would be THE PROJECT. :eek: :eek: Not sure if it will be even possible but I have 2 recommendations.

1) I believe Porsche racing cars have adjustable sway bars so you might want to see how they accomplish that.

2) What about some kind of latching mechanism. Thinking of a sway bar as a "C" for simplisity's sake, leave the top and bottom sides of the "C" connected and then just have the middle section latch in. Example ----> l_l ( latched) to l _ l ( Unlatched ). Or, a simpler way. Install "hooks" instead of zip ties onto the main rods ( not sure their correct name but you get the idea ) and the connect the whole sway bar to a servo. Depending on the servo's position, the bar will be either inside the hooks and fuction properly or off to the side a little and disconnected from the hooks and the suspension has more free play in it. To better understand what I am trying to say, take a look at your truck ( in your head anyway ) from the top and notice how the sway bars are actually installed. Now picture moving them to the right a little. Notice how they are still there but no longer in the way.
:rolleyes:

Just remember, All good ideas start simple.

Also, Its nice to see that this tread is back to normal, as compared to a month ago where it was used as an ICQ/IM.

[junk4calata]

BTW HB, I think you should be thinking of a new radio soon or disabling other channels if you want that. This is why I bought a 6 channel ahead of time because I learned a long time ago - Its NEVER done.

[bluesy]

jeepinator..... and Dr.Doug..... my humblest apologies....... I honestly forgot about you gentlemen's websites. Both of which contain invaluable information for those of us LUCKY enough to own and drive this fabulous truck. When I read your posts I even got my wife to give me a slap on the head to wake me up. Again, Sorry......
