Hi Folks,
Long time no visit. What's new in the world of the NMT? I'm dusting off the old MT this weekend for a blast, it's been about 12 months now.
A baby and a new car have taken a toll on my hobbies, fortunately they are all exactly where i left them, NMT, RC10FGT, Micro RS4.

Hi Brassmonkey

Yah I received the PM. I'm going to hang out here for a while. But I have been trained well at how to lurk around without being noticed. Maybe not, but I will keep an eye on the other sight.

NMT4me

I tried the fuel tubing around the stinger opening. It would not stick to the fuel line. The guy who cut the ant mast in half and used fuel tubing had a great idea. Easy and done.

Hicountry,

When I shoo gooed the fuel line to the stinger opening, I also put a bead of CA on the inside of the body and let it run into the goo. Also, the goo needs to set up for a while and get tacky before putting it on the body. The tubing held on for a couple weeks but I've had to replace it once or twice.

I think I will just rely on the heat shield tape then. I'm going to a shop today that has a 1/24 indoor track. I'm looking at (driving on) several to make plans for my own. This RC stuff is just too adictive!!!

Hey guys, I've decided to try out a .12 Sirio slide and pop into my racer. I was wondering which type I needed to get, threaded or SG? Thanks!

KOLOR KRAFT
01-10-2003, 03:36 PM
threaded i don't think the sg shaft will work.

SpoonEK
01-10-2003, 04:48 PM
thanks Kolorkraft..... What is the advantage of threaded over SG? Does anyone know of someone with a Sirio in a NMT? I wanna get an idea of what kind of performance I'd get with this engine in the NMT.

Hey everyone, just checking out what's happening. I just got a whole lot of new stuff for my NMT including Ti shock towers (from F4i Modelsport Racing (http://f4iracing.extremevelocity.net/) ), Kyosho Twin Caps, Robinson Racing Vented Flywheel, and Powerline Heatsink Engine Mounts (all from Tower Hobbies (http://towerhobbies.com) ). Does anyone have any videos of an NMT like jumping a car or house? I'm in the mood to see some car breaking landings.

is it OK to pack the diffs with white automotive grease?

KOLOR KRAFT
01-11-2003, 04:09 PM
i would perfer ofna diff fluid 50,000 in front and 30,000 in rear but i have used vaseline it is rather thick and definetly tighten up diff action so it does not slip that much ran three race weeks like that and worked good.

Exille
01-11-2003, 06:50 PM
this grease i have is vasoline times 4 heh, its called Sta-Lube super white multipurpose grease doesnt even move when jiggled, works real well though i packed everything with it, went bashing with my friends at the high school today, this thing flys when adjusted right, and mine is still completely stock, pretty durable too, i hit a curb about 3 times on accident and about 3/4 throttle and nothing broke, was raining at the time lucky i didnt fry anything, would balloons work to seal the receiver and the servo batts?, does it matter if the fl wheel has scratches? about all the wheel bearings are shot after that run, are there any stronger ones out there? (just got this MT if you havnt noticed already)

brassmonkey
01-11-2003, 07:52 PM
Yeah, but the question is, will the vasiline still be as thick at high rpms. BTW, I think I got my front and rear diffs mixed up when I rebuilt them, I think I have 50,000 in the rear and 30,000 in the front, what can I expect performance wise?


EDIT: aw, crap, I mean 50,000 in the back 30,000 in the front

I need to pick your collective brain. I have new batteries in my transmitter, new batteries in the reciever, all the connections are properly plugged in, the crystals are seated and there are no bare or broken wires.

Anybody have any idea why I'm getting ZERO response out of my receiver? There is absolutely nothing happening. No glitch when I turn on the receiver or anything. All I can think of is a bad on/off switch. Am I missing anything?

Exille
01-11-2003, 10:29 PM
check the crystal in your radio, check the antenna, open the receiver and check your components, make sure theres no dust or anything in it, ummm check to be sure both crystals are the same frequencies..ill say more when i can think of other problems

Crystals seem to be o.k. Checked the on/off switch wit a volt meter and the switch is working. I've got power going to the receiver, but nothing appears to be coming out. I know that moisture or debris is out because the receiver is ballooned and the end was shrink wrapped.

I haven't got a clue how to check to see if the crystals are working.

It seems like you and I treat our trucks about the same, beat but well taken care of.

I have not had any trouble with my receiver yet, but 16 years working on electronics has taught me that you can not beat them up a lot and expect them to last.

If you read voltage to the board below the battery connector on the receiver then a componet in your receiver is toast. May as well buy a better receiver, or the same one as it is perfect for the job. If you do not read the voltage than you have a bad connector, bad batteries, or a broken wire.

I doubt the ant. wire is the problem. I assume your transmitter ant. is inches away from the receiver when you do this.

I forgot the switch. Plug the battery pack directly into the receiver. If that works then the switch is probably bad.

Don't forget what Exille suggested.

NMT4me
01-12-2003, 12:28 PM
Hicountry,

You got it, it was the switch. When I plugged the battery pack into the switch, and turned it on, I got a reading on the back side of the switch however, when I plugged it into the receiver, I got nothing.

I plugged the pack directly into the receiver and got a reading. I swapped the on/off switch from an old Futaba and just like that, problem solved. Thanks to you and all who offered up suggestions!

ive heard of people using straight 30wt automotive oil in their diffs, thats all i have access to, would it be ok to use it?

KOLOR KRAFT
01-13-2003, 02:29 PM
MAYBE 90 WT.???????

Exille
01-13-2003, 02:53 PM
would 90 wt work?

gometro333
01-13-2003, 03:14 PM
Putting 90 wt would be do nothing. Your better off just filling it with grease.

Exille
01-13-2003, 03:44 PM
well i did pack it with white grease before, that wasnt good though, after the race there was white grease everywhere heh, it oozed out of the diff/bulkhead, so no automotive oils would work? 30 wt, 40 wt, 90 wt? none of them?

gometro333
01-13-2003, 04:05 PM
Ok I just said it really wouldn't do anything. A bottle of 30,000wt oil from OFNA is only $9.49 at towerhobbies.com. If you can't spend 10 bux right now then wait. Filling your diffs with oil is not a necessity. Your NMT will not break because you didn't put oil in the diffs. I've had my NMT for more than two years now and I still haven't filled them. I plan on doing it, but it isn't essential. But if you are going to fill the diffs, then go for something like 30,000 or 50,000wt. Some people put 100,000wt in. While others use JB Weld to completely lock the diffs all together (I wouldn't do it, but some do). The oil you use is entirely dependent on what kind of unloading your getting. If you think your is losinga lot of power than you wanna go thicker. If you're not losing much then go thinner (not 90 wt thin). If your not losing any power then skip the whole process and spend 10 bux on something else.

boy, a lot of issue talking about grease in the diff.. I personally don't like putting grease in the diff. but a little helps keep them working correctly. Now for grease to help lock the diff. is something not new to the NMT. A heavy oil/grease is a good way to go for a low budget upgrade, but I would go with ball diff.. At least they can be adjusted by tightening or loosening a screw. HPI sells them for $38.00 US dollars (part #- A958). Towerhobbies.com got them for $33.99 US dollars. With the new powerplant that got installed into my NMT, traction has become an issue with the 2 of the 4 wheels spinning. I'll be upgrade to ball diff. when the bevel diff. give out. :cool:

Hicountry
01-13-2003, 07:57 PM
As long as you use O-rings to seal the diff you can put anything you want to into it. What do you want? If you just want to lube them then pack it with wheel bearing grease. If you want to limit the slip then go buy the correct silicone fluid.

I learned this the hard way. I decided I wanted mine locked so I packed it with JB weld. Worked great until a rock jammed one tire and kept it from turning. The other tire could not turn because it was locked to the first one. The result was a stripped ring and pinion.

I have learned alot know about shimming the gears to limit slop. Something I should have noticed on my own. Unless you do not play around gravel and sticks then I would not recomend the JB Weld. Not for pavement either. Way to much oversteer.

Can a nitro mt racer take a bashing? I was planning on buying this kit and dropping in my fr15 engine from my rs4 3 (which i hate) but im not so sure anymore after reading this thread. It seems as though the car breaks easily.. Is this true?

When my NMT Racer was completely stock I jumped it off my two story house on to pavement and all that happened was a shock popped off. Now I have Ti shock towers and better shocks and I plan on doing it again. The NMTR is also good for racing.

like i said earlier maybe 90 wt. i do no 90 is thicker than 30 if this is all you have 90 will slow the diff action down better than 30 that all i said. as for grease it usually just flings auround inside the diff so if you use grease you will not be slowing the diff action down and dosn't do much good exept make a mess if you use grease just use a little to cut down on friction and wear on the gears that is all it is for. i said earlier i have used vaseline and i race this truck it dos slow the action down and sticks to the gears well for friction and lube try it take it apart and you will see it dosn't fling around like grease, or brake down like some people think, this is a tried and true method for a cheap quick fix to slow the action down.ON that note the best possible sticky stuff to use would be ofna or mugens diff fluids lighter in the back because way to much traction in front compared to the rear i personally use ofna 50,000 in the front and 30,000 in the rear i could tell the diference and the feel of the truck with this combo. LIKE I SAID IN A PINCH TRY ANYTHING AND CHECK IT TO SEE IF IT DOES GOOD OR BAD KEPT TRYING COMBINATIONS THATS ALL. i was even going to try honey because that was handy at the time i also didn't want to buy any fluids to see what it would do that why i would try anything to see if you are going in the right direction just don't make the cheap way permanent if you notice the difference with the stuff you have lying around then make a choice and buy regular diff fliud...:)

My new rims wont go onto my mt. It didnt come with any adaptor for it either. If they are HPI wheels why aret they a direct fit?

Hicountry
01-14-2003, 04:24 PM
HPI makes wheels for AE and others also. If they are front wheels for a 2wd they will not fit. I do not belive there are adaptors for that.

nmtr13
01-14-2003, 04:30 PM
yea ur rite they are front. damn! wat am i suppose to do with them?/

Hicountry
01-14-2003, 04:33 PM
Can a NMT take bashing well?

Yes and No.

Because of the amount of front kick up the front suspension does not absorb abuse like a RC10 or XXXNT. A-arms break more often. Thats why some of us have gone to AL.

There are many building "SECRETS" that make the truck and body more durable. Find every one you can and use them.

The front uprights and hubs would be the next to break. Again only 7 to 10 degrees of kick up instead of 30 is what causes these parts to break.

I guess now that I try to put it on paper that is really the trucks only failing and I understand that it has to be that way to make a 4wd handle correctly.

Stay away from curbs and you will be fine. If you do not want to spend any money fixing things then take a lot of time, build it slowly and use every trick you can find to make it more durable.

Take the wheels back to where you bought them. They will fix the problem.

If it was mail order or whatever then take them to some races. DON'T mess them up. Leave them packaged and you will probably get what you payed for them. At least it would not be a total loss.

nmtr13

Hicountry

Well then you can talk to Tower Hobbies. The wheels probably cost about ten bucks. If they made the mistake then they should handle it at their cost. If you made the mistake then you will have to pay a couple of dollars to send them back. It may not be worth it.

Save them, if you grow in the hobby then you will use them. Maybe someone on the board will buy them.

so what are the secrets to make this truck more durable. Can i buy a chassis with more kickup?

Hicountry
01-14-2003, 11:30 PM
JFawwaz

As far as the kick up, well I guess anything can be made. Nothing is comercially available right now. As I understand it, it is all a part of steering geometry and drivetrain binding. In otherwords you may not like the effect of increasing the kick up.

As for durability......start at page one and read until you are cross eyed. Then read again. Everyone here is teaching from expierience. The two books that I used were Power Tuning and Painting &Detailing available at your lhs or www.rcstore.com

Remember that just because it is on the net does not make it true. That is what is nice about this forum. If someone is full of crap twenty people will tell you so. Someone will eventually come up with proof and then you will know how to go.

AllenJO
01-16-2003, 12:13 AM
Proline makes a bunch but my experience is that they are short on decals. I don't think that any body will survive running it at speed into/under a fence. Suggestion: buy yourself a tube of Shoe-go, and use it to re-inforce or repair bodies. Incredible stuff.

I recieved a Mt roller on a trade. I planed on doing a .21 conversion. Does some one make a steel spur gear. what are some other NMT hop-up companys out there. Could I also so get some URLs for some NMT pages. SS R/C Racing (http://www.ssrcracing.com) offered to make me an exended chassis and extended upper deck for the NMT. I need a engine mount, flywheel, clutchbell, and clucth shoes so I planned on getting the New Era .21 kit.

Everyone should go to the above sight and buy stuff because the guy who runs it will make anything people request (if enough people request) but he needs to have people buy.

Hey M16,

I installed the gear today and ran it. Had to fit the prongs to the clutch. The only thing that went wrong was that I did not listen to you. I did not buy a hardend pinion. After nine tanks of fuel it stripped. NINE tanks of fuel!! That is the most I have ever been able to go without a breakage of some sort. Thanks again for the part.

M16-A2
01-19-2003, 04:27 PM
You mean the clutchbell stripped? I do recommend you go with a hardened clutchbell like the Duratrax ones listed on my site:
http://www.personal.psu.edu/users/s/l/slw265/Web_Page/MetalSpur_Page.htm

I've run countless gallons on the Duratrax bells and a metal spur without much sign of wear and no stripping:)

Hicountry
01-20-2003, 03:18 AM
Yes I stripped the clutch bell. It was fun though. I am looking for a hardened bell now, but it has to be 12t. I really like using the non adjustable motor mounts. I guess if I was not so busy I could mill up a cradle for the motor.

Thanks again for the gear. It works great.

I just installed an Onfa 12t clutch bell with the MIP/HPI clutch. I had to lap .050 off the back of the bell. It is a little bigger( a few thou) and the gear dia. is a little smaller( again a few thou) but it worked perfectly. I prefer to use the non-adj mounts on the .15FE. With the difference in gear size I might be able to go to a 13t. Time to take some measurements.

I did not realize how crappy my clutch had become. It took a while to readj. the carb. It really was amazing to watch my .15FE spin the tires.

I sealed my diffs with o-rings (Onfa Blue). Then I filled it with Onfa 50K silicone fluid. Maybe a little much in the rear, but it works pretty well.

Those springs that HPI sells to put tension on the spider gears to limit slip? They seem to work. At least a little. Not enough to justify the cost, but I had a rear shock spring sitting around for a 1/24 car. Same size and really stiff. For free it was worth trying.

Have fun

Hello,

I have a few questions about my Nitro MT. What is a good shock set up for the MT to reduce bounce if you are running with the stock shocks? Is it worth upgrading to the f/r super shock set? or are there better shocks that will work on it? Also will the Proline Chevy Silverado Body made for the Traxxas Stampede work on my MT? Thankz!!:confused:

What ever happened to the HPI Forums. It seems a little stream-lined.

Where else can I find MT forms other than here and ****.

I'm working with SS R/C Racing (http://www.ssrcracing.com) on making a .21 conversion for the MT. It will include a new chassis, aluminum upper tray, motor mounts. look for it this spring.

default_uzer, I use the Kyosho Twin Caps Pro with blue springs all around. They have been doing a great job compared to the stock ones which would ooze oil out everytime I took it off the stand. The slipper clutch will simply reduce the number of stripped spur gears. I don't know how it all works but thats what is does.

MERCENARIO we are making a hpi chasis stock length to accept the .21 out of titanium should have fist prototype here friday and it looks awsome. over 4mm thick going to be able to except both stock motor with pull start or without also .21 to really make it quick. we also have shock towers and upper decks removable and non removable, front steering braces,and wait to you see the dogbones are really strong all my parts are made here in AMERICA. if anybody has a sugestion for other parts my ears are open. and remember all parts are TITANIUM only.

But I am a major Monster Pirate fan, I own one also. Do you think you guys could design a fuel tank brace for it or some type of a mount? The tank just kind of hangs there, and is not too stable! I hear fellow MP owners talk of this also! Again thanks for your wisdom!

Check out OFNA's homepage at www.ofna.com for more details. I have one and it kicks ass. It is all time 4 wheel drive but could easily be converted to 2 wheel drive. This thing is very sturdy coming stock. The only part I have had to replace so far is the plastic spur gear. I ordered a metal one and it is on its way. You also have the option with locking the center diff for equal distribution of power to all four wheels. Make sure you have plenty of open space, 'cause.....this thing gets from one place to another in no time. :D

RE Slipper clutch,

The stock setting of 1/2 turn out is way too loose IMHO. I run mine between 1/6 and 1/8 turn out with no ill effects and that's with a Picco .15. If you're running a .21 engine maybe 1/2 turn would be necessary, but if you're running one of those anemic HPI .15 FEs then a slipper clutch is probably a waste of money (unless you hit things alot). It does provide one other advantage: to use spur gears other than the stock 52 tooth. The slipper clutch allows you to use any spur gear designed for use for the HPI 2-speed with one caviat -- if you go much below 49 tooth you'll likely have to rework the engine mounting holes in your chassis in order to get a proper gear mesh.

Default_uzer,

"Crappy" is a bit too strong. It's just that the FE has a single-needle carb and only puts out a little more than 1/2 hp. Most of the .12 and .15 engines that you see other posters talking about put out between 3/4 and 1 1/4 HP, and the .21 engines put out twice that. Thus my "anemic" comment.

Just about any .12 or .15 long shaft, side-exhaust engine will fit. You'll need HPI's engine mounts to use another engine, but that's what those other 6 screw holes (actually the last 4 of the 6) in your chassis are for. You may need a new flywheel and may have to change throttle linkages depending on what type of carb you get.

A rear-exhaust engine will work, too, but it can be a tight fit. Not for the engine itself (you'd mount it the very same as a side-exhaust), but the exhaust header; there's not alot of room between the engine and the rear shock tower, so you have to show care in what header you buy. All the more so if you want to keep using a pull-start. But if you want to continue using your current header and pipe, stick with a side exhaust.

As for which engine, there's lots of 1+HP engines on the market. I have a Picco, but O.S., Fantom, Megatech also have alot of fans. That new Traxxas 2.5 is also getting rave reviews. HPI's .12SS and .15SS are good, too. When your FE is shot, you can ship it back to HPI with $99 and get a .15SS. But if you shop around, you can find other engines for the same amount or not much more.

default_uzer
01-24-2003, 12:20 AM
AllenJO,

OK, I see what you mean now! It is a good stock engine for beginners. And once its shot I can buy pretty much any .15 or .12 wether it is O.S., phantom, traxxas, ect, but just keep in mind, if I want to stay with a rotary carb, and not have to change the linkage, get an engine with a rotary carb. I also need to make sure it has a long shaft? Is that a SG shaft or the standard shaft? I also need to get the HPI engine mounts as well right? No matter what engine? As far as the fly wheel I can figure that out. Willl the new fly wheel have an effect on the engine placement as far as the mesh setting?

Thankz!

My FE has decided to quit working. It has good power to the plug. The plug glows just like it is supposed to. I tried a new one anyway. The engine has 1.5 gals through it.

I have not tried a second glow charger, but I have used a second battery. The charger has a meter. Kinda hokie but it reads good. It also reads bad when you put in a dead battery.

I noticed something wierd. I assumed I was not priming it enough. Prime it some more and it would start. Now if I intentionally hydrolock it it will start. Its hard, but it will start.

It runs great once it starts. I also put in a new clutch so I may be fooling myself.

It seems to have good compression, but I may not have noticed it falling off. I just can not believe that after 1.5 gals it is worn out.

Any ideas?

AllenJO
01-26-2003, 12:31 AM
Hicountry,

It sounds like your carb settings may be too lean. If you pump fuel to it and it starts and then dies, especially when you hit the throttle, it's usually a sign that you're running too lean.

SpoonEK,

I love my Picco .15. Had it for almost a year. Powerful and reliable, and easy to tune. My observation is that perhaps it has more high-end speed than low-end torque. Best compliment that I can pay an engine: when it's shot I'll either rebuild it or buy another Picco.

Default_uzer:

You can use either rotary or slide carbs. With a slide carb you'll probably just have to get a different throttle linkage. But you may have to do that with another engine with a rotary carb. Your local hobby shop would have all the parts that you'd need to make the switch (whichever). You do need an engine with a long crankshaft, not a short crankshaft (and I believe you're right that the short shaft is referred to as SG, but check). Don't recall if I mentioned it, but there's a good chance that you'll also need to purchase another flywheel no matter what engine you purchase (except for another FE).

Hey AllenJo,

So if Ineed a new flywheel, Does it have to be a flywheel made by the manufacturer? or some other name brand? If so any that you recomend? Again thanks for your tips, you have been a wealth of info!

AllenJO
01-26-2003, 11:45 PM
HPI does make a lightweight flywheel -- actually 2, 1 for pull-start engines and 1 for bump-start engines -- but other companies make them, too. Powerline is one. Sizes can vary a little depending on whether it was designed for a pull-start or bump-start engine (latter is sometimes smaller in diameter), also number of mounting posts for clutch shoes can vary (usually 2 or three posts; HPI's stock clutch is a 2-shoe). Some even are milled/cast with little fan blades, presumably to aid in engine cooling, or are annodized (colored). I would imagine that you could use any designed for a .12/.15 engine; just make sure that you get one with the correct number of posts for your type of clutch.

Two biggest issues in installing a new flywheel is getting it seated tightly against it's collet so that it doesn't spin separatetly from the crankshaft, and making sure that it doesn't rub against the brake rotor (the flywheel and brake rotor overlap with only millimeters between the 2).

Another comment: to get the most out of your FE or a new engine, get HPI's racing clutch.

Things that I had to replace/ repair / upgrade. (Just my 2 cents)
1. Front suspension arms/ upgrade/ RPM aluminum suspension arms.
2. Increased length on the fuel tubing to 2ft.
3. Added a fuel filter
4. O.S. .15 CV-RX engine
5. Stock rear axle/ replaced / with stock rear axle (still haven't got that part in. whats taking soo long.)
6. Add a 1.5 ft long raditor tubing over the exhuast. (to prevent oil from drip drying every where on itself, now it spits out in the rear of the car.)
7. Stock shock towers (may need to be replaced if they start cracking, I know I need some new ones.)

The NMT will give some problems, but that is what comes with a nitro truck. All problems I have occured were simple ones. The only thing that is increasing my downtime is for that d*** axle part to come in. I'd wish he would hurry it up some, its been a month now since I order.

By cutting off part of the clutch shoe you increase the RPM that the clutch will engage at. Most people go to the second hole and remove the portion back to the first hole.

Well, I'm finally happy for getting the part in. I already got it installed and ready to go in the morning. Reason why I increased fuel tubing lenght is that it gave a more realible idle to the .15 FE, when the truck flips, I'm able to get to it in time before it dies. I found out the reason why it took soo long for the part to come in. It came in about 5 days after I order it, but his wife, that works there too, missed placed it. He found it 2 days ago, but forgot to call me to tell me that it was in, but luckey enough that I'd called in to see if it was in (which it was now). So all it was a little oops in placing things around. I'm not too mad, now all I need now is snow to come down from the sky.

LearjetMinako
02-02-2003, 09:32 AM
The long tube has to go between the fuel tank and the carb.. From the way you said "return tubing" I thought of the one between the exhuast pipe and the tank.

And for those hex, I leave them be. Just be careful that the axle pin will/might fall out too. What you could do to prevent this from happening is to use thread lock on the hex. (Even I forgot what they call those things exactly)

02-02-2003, 09:24 PM
How about a just a second or even third tank of the same size? You can mount the tanks all over the place; like on the rear bumper (requires a little cage to be made so it isn't broken) or on the steering plate. You can really put them all over. Just takes some creativity.

Just putting a bigger tank would require you to cut away part of the upper deck and if the SNR is some what new, it will viod the parts warrentee.

I would go with teh multiple tank idea.

Multi-fuel tanks are a bad thing to do. I should know from exp.. The problem with this idea is pressure, but can probably be solved with a fuel pump. And I found out the hard way with my R/C trainer aircraft.

I'll submit a poor diagram later, maybe, of the idea.

My dual tank setup ran just fine with plenty of pressure.
It was a little more trouble to fill both tanks and run the extra lines, but it is worth it under certain circumstances.

I guess, maybe, I could be wrong about the pressure thing. But still, its not my area to say "I wouldn't do that if I were you". At least, if anything goes wrong and the engine dies, you are able to retrive it (I had to climb a tree to get my trainer down).

Hehe that must have been a chore :) I dunno, there may be some compression difference between a RC and airplane engine(never run a plane myself, so can't really say). I do know that the XTM 15 which was powering the dual tank setup has loads of compression, so it provides adequate pressure through the system.

It would really depend on how much pressure the engine was giving the whole fuel system.

I've run a dual 75cc setup. The problem is if you land tail-first from a jump you will destroy the rear tank. On my NMT that I sold I installed an OFNA buggy 125cc tank. Took about 20 minutes to install and required one part cut off of the plastic upper deck then a hole drilled and countersunk into the chassis to mount that part back on with the OFNA tank in between.

I fixed that problem as well by fabricating an aluminum safegaurd for the rear tank.

Thanks.

P.S. Maybe some of you guys/gals could make a top 10 or 15 list of items to replace.


# Things for a tough life + Things to do later section

1) Fit heavy duty plastic ball joint ends Robinson RRP 2013
or nylon ASSOC AS6273 Chassis ground away
for servo saver
2) MIP 1074 Stainless steel or Hammad Ghuman Titanium 8310 ball ends
a must for all suspension joints. Start fitting from the rear
suspension turnbuckles then front suspension lastly steering.

3) Fit Kimbrough Servo saver to replace the plastic straight arm type.
Grind the chassis lip to allow clearance between servo saver and chassis
lip.

4) Take off front and rear suspension arms and boil in hot water for
10 minutes. This adds flex to the arms which stands up to knocks better.

5) Replace the front and rear suspension turnbuckles with Lumford or
Schumacher titanium turn buckles.

6) Fit MIP Gold Shock Shafts front-1048,rear-1049 give much
longer and smoother movement as they are pre-coated
and have a polished finish.
Traxxas type ball end inboard S/Steel outboard
7) Rear suspension inboard ball joint anchorages
replaced by TRAXXAS ball end bolt through type joint.

8) Fit stronger shock towers front and more important rear. Make your owm out
heavy duty plastic or buy alloy sheet and cut out against current profile.

9) Standard brake and throttle servo horn linkages replaced by stronger
servo horn arms Throttle & Brake linkage changed
NOTE battery cover cut to allow 5 pack
10) Cut battery cover if 5 pack "AA" used slicking foam
padding under holder to insulate and cushion batteries

11) Fit HPI competition clutch shoes, trim to middle hole length for medium
speed clutch drive take up.

12) sts .12 1.3 hp with fantom pipe raw steel

13) When fitting fly wheel starting engine replace the standard tall engine
mountings for pull start engine with the lower drilled out mounts so wheel
starting can be carried out. Fit 1/8 ins washers between engine casing and
chassis engine mounts, gives more engine clutch bell to chassis clearance.

14) Replace needle bearings in clutch bell with 4 small roller bearings.
(used to give better support on long shaft)

15) Replace standard dog bone type drive shaft with titanium bones

16) Fit HPI optional heavy duty diff crown wheel A856 and pinion gear A857
for beefed up transmission. Start with rear diff first then if truck used
extensively fit front diff with these items.

17) Fit a rear suspension hinge pin brace make from alloy 3/32" thickness
or from heavy duty plactic 1/8-3/16" thick. Use longer threaded hinge pins.
Cut reat bumper off to allow brace fitting HPI 4wd

For a larger fuel tank that any one can build. Today, in my Horticulture class, I came up with a very simple, cheap, and easy fuel tank to build. All it should require is a bottle, cocking (hot glue, etc), metal tubes or fuel nipples. Its kinda stuipd, but I like the idea.

I'll will be using a Power Aid bottle that is 12 fl.oz. (355 cc). This should give me a runtime on a O.S. .15 CV-RX engine, 24 minutes, tops!!!! And becuase that the bottle's lid is a nice size to fill it up with. My plan is to strap the tank (bottle) to the back of the suspension tower in the rear with a tube clamp or rubber bands.

Hopefully I'll get it competelied before sundown, so I can try it out, (not on a full tank of gas, I'll save that for another day when I can drive for 20 minutes straight).

Remeber that is just an idea, and a kinda stupid one at that, but at least you can dream and design things in this hobby. :cool:

Haven't tried to do that yet, and I don't feel like cutting a 3" dia. hole in the back of the body. I'll find another way to this, hopefully it will be inside, low to the chasis, and carry at least 125 cc of fuel.

Take a small piece of paper, compress the front shock a little and stick the paper between the chassis and the suspension arm. Most of the time the paper will be held by the suspension arm hitting the chassis, especially with the shocks mounted to the inner mounting positions. The problem is that the aluminum chassis is digging into the soft plastic suspension arm, causing a weak spot.

Agree with M16-A2, stay away from ball diffs if you're running off-road. Better to invest in heavy duty diff gears for the rear diff (front diff is under less stress and stock diff gears work fine).

Great Lakes Hobbies used to, and may still do, sell HD diff gears at 30-40% below HPI and Tower Hobbies. Haven't checked in a year. That's where I purchased mine.

People,

I have a small problem. When my NMTR is on the stand and I spin the wheels by hand, everything seems okay except for the front left wheel. When I spin it, there is a little resistance and the whole assembly moves up and down so that the shocks are compressed a little bit, then when I continue to spin the wheel the assembly lowers and the shocks are uncompressed, this repeats as long as I spin the wheel. When the car is on the ground it seems to freewheel pretty well but the front left wheel does wobble up and down a little. It also seems that the steering is pretty tight. I built it and wonder if overtightend something but the wobble is baffling me. I checked the turnbuckle's length and it checks out. I don't have much time to wrench and am only $50 away from running this car for the first time. Any suggestions? Would it help to examine the inside of the front differential or what? Any advice is much appreciated.

gaus

AllenJO
02-09-2003, 01:18 AM
I was about to suggest some things re the wobble, but then realized that your truck was brand new. If it were old, I suggest that you inspect the large ball bearing on inside of your wheel hub. Still, check to make sure that you put both the inside and outside ball bearing in the hub. Also make sure that you put the metal sleeves that house wheel hub assembly's top and bottom screws. If you left either out, there would be wobble. Lastly, check to make sure that your ball-end screws are in tight. Don't think your front diff is the cause: the a-arm and turnbuckles support the wheel hubs and wheels; front diff has nothing to do with that.

As to the steering, make sure that you assembled the steering assembly correctly -- that the bushings aren't binding and that the shafts that the bellcranks ride on are in straight. Down the road do consider replacing the 4 plastic bushings in the steering assembly with ball bearings -- you'll need four (4) 5mm x 8mm ball bearings. By the way, re tight: you aren't trying to turn the steering assembly while the steering servo is powered are you?

But the clutch proved to be overwhelmed when I melted it to the spring. Got rid of the stock NMT clutch that came with the kit and replaced it with the HPI Racing Clutch (first hole). Drives ok now.

And also been busy trying to find a new job to support this hobby. Grass doesn't grow in the winter, bummer, I'd wish it did so I can get paid.

Hi guys, i just bought a pair of front universal dogbones(UD) to replace the standard dogbones that came with the kit. After assembling, the UDs keep coming out...the front wheels just slide out together with the UDs. I found out that the outer ball bearing of the front knuckles kept popping out and they pull the UDs out together with the wheels. What should i do to rectify this problem? Thanks in advance. :confused:

NMT4me
02-15-2003, 12:48 PM
Godspeed,

This may sound like a stupid question but did you put the inner bearing back in the front knuckle? It seems to me like the only way that the outer bearing can pop out is if the inner knuckle bearing isn't in place and the outdrive is pushing against the back of the outer knuckle bearing.

Did you get the MIP CVD's or the HPI set? From what I understand, the MIP's are a little short for the MT.

Godspeed
02-15-2003, 07:28 PM
NMT4ME,

I did put the larger inner bearing back into the front knuckle...seems to me that the UDs kept pushing the outer bearings out. After assembly, the UDs will come out of the diff shaft and they pushes the outer bearings out together with the wheels. :(

BTW, i am using the HPI set...not the MIP CVDs.

NMT4me
02-15-2003, 11:35 PM
Godspeed,

It sounds to me like you may be using the wrong cvd's. I'm guessing that your using the rear cvd's instead of the front CVD's. Compare the ones you have with the ones that come with the HPI NMT Racer:

http://www.hpiracing.com/graphics/instr/nmtracer/nmtracer11.jpg

and:

http://www.hpiracing.com/graphics/instr/nmtracer/nmtracer12.jpg

Your front cvd's need to have the big flange to rest in the inner knuckle bearing (part# B030).

Take a look at this page:

http://www.hpiracing.com/walkthroughs/rebuild-cvd.htm

The 2 cvd's on the left (first picture) are for the front. the 2 on the right are for the back. Notice how the ones on the left have a big flange where two pieces of the CVD are joined.

If you use are trying to use the ones meant for the back up front, the whole cvd will pass right through the larger inner bearing (part B030) beacuse it has no flange, and the wheels will fall off.

The rear of the truck uses the same smaller (part# B022) bearing for both the inner and outer sides.

I hope this helps.

Godspeed
02-16-2003, 12:46 AM
NMT4ME, thanks a lot for the information. :) You brought up a very good point there. I have checked, I am using the wrong set of universal dogbones, cos the whole UD just passes through the inner bearing. I shouldn't have trusted the guy at my LHS. :mad:

Glad to help! Once you get the CVD's sorted out, let me know if you have a problem with them coming out. The HPI CVD's are supposed to be slightly longer than the MIP CVD's and they should not come out. I'm curious to know how well they work.

Hello,

I am just now starting to run on the ground a NMT racer I built. Besides a couple of initial problems that have been overcome, I have one more. When I throttle the truck, it begins to move forward then as I increase the throttle it pretty much just crawls around even though the flywheel is spinning rapidly, and engaging the small gear (pinion) smoothly. The wheels spin and have some power behind them when the car is off the ground, otherwise the engine is still a little rich. I am leaning it slowly but could this also be a problem related to my clutch? Any suggestions appreciated.

Well after a whole day of tweaking the suspension, my conculsion for the setup is "This bites". I can't get the suspension to act in the way I need it to, but then it came to me as I was banging my haed on my computer. What about the springs! That is my solution, stiffer (harder) springs will solve this problem. Tomorrow I'll be at my LHS watching a 4wd stock/mod sedan race, I'll buy the spring then.

Gaus: Check to see if your brakes are dragging. I've got almost the same engine and it should push and shove that truck around like nothing. What is your gearing, type of clutch (stock, 2-3 shoes, racing). Try turning the spur gear with your hand to see if the driveline is freely moving, if not, somewhere in your driveline is your problem. :cool:

Four stroke eh? Well, I saw one guy with the thread .21 NMT update (in nitro forum) who looked like he had a 4 stroke in his nmt.

Well, I think Tower has lost my order w/ the ofna hyper.:( :mad: :eek: They said if it's not here by teh 26th, then they will resend using Fedex. Man I hate them now.

(in regards to a previous post)

My clutch is the stock clutch. How exactly does the clutch work, this I am a little confused on. I did not look at it carefully enough when I put it together. I don't think the brakes are dragging because it freewheels fine on the ground with the engine idling. It accelerates (the car) so slow compared to the increase in RPMS. Darn, this little car is so cool I just want to see it move fast.

SleepyGMan,
I don't really know if a 5-cell pack will fit in the stock radio tray, never tried it. Like M16-A2, I replaced my stock radio tray with an alum upper deck, and do exactly as he does. However, I'd think a 5-cell hump pack should fit (a flat pack, not).

I dumped the radio tray because (1) a wanted the stiffness that an alum upper deck would provide; and (2) I absolutely hated the radio tray -- I thought it ridiculous that I had to disconnect 2 servos just to change batteries. Glad to see that HPI fixed this design error in the Type SS.

I dumped akaline batteries because I had a near-disaster with a WOT due to a dislodged battery after a big jump, and decided that I wanted the security of soldered NIMH receiver packs. Packs have more juice, too. Since I also race electrics, moving to rechargeable packs wasn't a problem. Best move I ever made.

As I said in the last post the 5-cell pack will fit in both the Powerline deck and the stock tray.

My brother's NMT has a stock upper deck and tray, and he uses the exact same 5-cell pack that I do.

Gaus:
The clutches work off of centerfigerical force, but have a spring installed to pull the pads (shoes) back when the force is less. Its like taking a bucket and swinging it around. The faster you swing the more the bucket pulls.

Now you said your clutch is stock. Check to see if the pads are going in the right way. And don't have them on backwards. As you said the drivetrain moves freely, I'm a little stumped on how you can't get it really moving. Check to see if your throttle link opens the carb all the way. Try a 2hi/2lo fuel mixture on the needles and tune it from there.

I posted the clutch configeration. Note the way the clutch pads are in.

LearJet,

Actually, I think my clutch is the racing clutch because it came with the NMT Racer kit. Here is what I have to say now: should the clutch bell free-spin easily or should you have to spin it a with a little bit of force, no freewheeling? My clutch bell is tight and will not move on its own unless I move it around with my fingers..

The clutch bell should move freely. But if it moves too easily, add some kind of grease on the needle bearings. I have the racing clutch installed on my NMT and it works good. Had to replace it when I burnt the clutch pads down. My only guess left is that it has to be the engine. I can't really help much there, only if I was there I can help then. Sorry. I'll try to find a solution.

On the racing clutch, You still have to make sure that its on right.

gaus, do this little test. From the bottom of the chassis, hold the spur gear still (it's the plastic gear that the clutchbell engages), grab a front wheel with your knees, then turn the opposite front wheel. There should be a lot of resistance but the slipper clutch should slip after you put a lot of force into it. If it slips easily then your slipper clutch is too loose. Take a 2mm Allen wrench, loosen the grub screw on the adjuster nut, grab a front wheel with your knees and turn the other front wheel backwards, which should tighten the adjuster. You want to tighten it all the way tight then back off a half to a full turn and see if this makes a difference.

The only other thing it could be is the setscrews holding the drive cups are loose. The NMT Racer has two of these, one on either side of the slipper clutch.

PCC-

I tried your test. It was somewhat easy to spin the wheel, though there was resistance. In reference to above, you are speaking of the center diff set screw (grub) to loosen, crank the front wheel backwards while holding one still. Then do I retighten the 'grub' screw? If this is correct let me know. Thanks a lot for all the help. This is driving me nuts as I have been waiting to drive this car for a long time and only this weekend did I finally install the hi-torque steering servo and receiver to boot.

PCC,

Also, when I do the the thing with the grub nut, holding one front wheel stationary and rotating the other backwards, it just continues to spin and never tightens up to back off any.

Next chapter in my dilemma:

I think the racing clutch is doing its job, I can see that there is power going from the clutch bell pinion to the spur gear. It must be in the center diff that the power is being lost. I think PCC was telling me how to fix this but it still aint working for me. I am not very smart and need some further specific instruction. IEEE.

Just as I had suspected, the slipper clutch is loose. Yes, you have to tighten the grub screw after adjustments so the setting doesn't change on you.

There are many ways to adjust the slipper clutch on these cars. One other method I used was to loosen the grub screw, and, while leaving the allen wrench in the grub screw, roll the chassis on the ground backwards to make the adjustment.

gaus
02-23-2003, 11:03 PM
PCC - Thanks.

I was able to rotate the spur gear while holding that adjuster nut with my finger enough to tighten it. This little car jets around my ice covered streets like a maniac. What a blast. I'm used to 1/8 RTRS and I am so glad to have built this car myself and for the help I got from this website. The OS .15 CV-X w/ the stock pipe is so quiet compared to my Savage. I can run it late night and not bother me neighbros.

ps. Now I know what a slipper clutch is.

RE Slipper clutch,

Although the manual says 1/2 turn, that's way, way too loose IMHO. Especially if you have a FE; don't even need a slipper clutch for that engine. 1/2 and even 1/3 out will just sap whatever torque your engine generates for no useful purpose. I run at 1/6 turn out (1 side of the hex nut) and have never broken or stripped anything, and I have a Picco .15 and run offroad.

Moss,

How do you attach the side skirts?

BTW I will be eternally filled with envy over your access to that plastic material. ;)

I could sure use some of that stuff on my 1:1 scale 4x4. Do some custom work on the cargo space, door panels, dash, etc. Maybe even build a cusom air intake box or a snorkel.

Oh well. I suppose working as a web programmer has perks too. I should be grateful for what I got.

Hey. Maybe we could work out a swap. I build you a web site, you send me a crate of that plastic and teach me how to bend it. :D Yeah, maybe not. :rolleyes:

Well I was right I cooked my FE. HPI refused to sell me a stage three kit for it so I bought an OS .15CVRX. I really did not think the FE was underpowered, but this thing really hauls now. It is a lot faster than it needs to be.

I took it out in the snow the other day. I used my paddle tires and it had more traction than it needed. I did not want an RC10 because they do not run well on varring surfaces. 4WD really does help.

I also have an electric buggy now. It is nowhere near as quick as my NMT, but it also does not turn near as well. I bought it for my daughter so she could handle a slower car. She does better with my truck.....Point and shoot and it goes.

I have added rush out drives to the rear diff. They ARE better then the HD ones for the NMT. An AE 1/10th buggy wing, I think the 1/8th are just to big. I will try to add a picture later. MIP clutch......instant power.

Does anybody know about some better side gears and spinder gears for the diffs????

As for HPI's lack of customer service. This is the last thing I will buy from them!! I really like my NTC3, and I was going to buy an SS!!

Everybody have fun!!

Whatsnext, I actually sell the bumpers and have been considering selling the skirts/spur guard. I have more information on my webpage www.mossdog.freeservers.com Email if interested.

As for the plastic I use, I work in the plastics industry, and have many resources to tap. The plastics used in the bumpers is a blend of polypropylene, I used this so that the bumpers can flex a little bit on impacts absorbing the energy. The bumpers on the other hand will not bend or deform or crack in anyway (much better that aluminum). They are not bent into shape (which can cause wallstock issues and failure points) they are injection molded in rough form then hand finished depending upon customers requirements/preferences (ie fit to different vehicle)

The skirts are currently held on my NMT with 3M automotive adheasive (this is for quick removal during my testing and to allow easy mounting of other pieces I am currently working on) But there are many locations that they could be bolted to the chassis ( I will eventually bolt mine when I have completed my other projects)

If anyone has any other questions visit my webpage and feel free to email me! Thanks Moss.

Hello Maxx 2.5. I would recommend checking the diffs and shimming them if they are not and checking the spur gear output cup joints (HPI # 76872) check the set screws and apply locktite to them I would order some new A-Arm trees as well (HPI #A456) boil them for 10min which allows them to flex in a crash and not crack. As for engine choice the most popular of engine choices in the NMT is the OS 15 line, the CV-RX being the most popular. Coupled with a high-flow header and single chamber pipe that NMT will smoke a 2.5 Maxx if geared properly. The Fantom FR15 (2003) model is much improved for more torque than the previous version. I think it would also make a good choice for the NMT for bashing. Basically it comes down to personal preference.

If your NMT still has the stock plastic "camber links" (HPI #A473) they will constantly pop off on you. I would suggest changeing them to some turnbuckles and good ballcups. Aside from that the stock plastic brake tends to heat up and fade easily, the fiber brake disk (HPI # A884) will make a huge improvement in the braking dept. Have fun with it its an excellent handling truck.

Check my webpage out www.mossdog.freeservers.com for lots of NMT pics.
