It's an enamel paint, very durable and should hold up(for the first roll or two).

Anodizing would be too expensive for just a single part. I may consider allodizing a cage or two, as that process or much cheaper.

Definately not true! I consistently jump my truck 40+ feet and after 3 years have only broken a handful of parts.(few a-arms and a shock tower)

The a-arms are the most fragile part of the truck(as they should be), but still won't break easily, unless you run W0T into a curb or land a jump completely or repeatedly wrong.

I guess it depends on what you compare their toughness to. It took a fall off my roof to finally break something on my friend's electric MT, and this was after jumping dozens of time over my pickup truck and landing all sorts of ways.

Until this past Wednesday, my NMT broke only one front A-arm and a rear shock tower (total cost $10 for both repairs - and that $10 got me a bunch of spare parts on the part tree! I love spare parts). Wednesday I landed square on the nose after flying about 25' horizontally and 6' vertically off a BMX track jump. I lost one body pin and broke the AA receiver battery holder. Not the swing-out housing, just the little thing the batteries make contact with. Cost to fix would be about $2, but bought a rechargeable receiver pack which I was already planning to do, so it really cost me nothing other than loss of drive time.

That same day my friend jumped about 5' horizontally and 1'-2' vertically with his T-Maxx, landed funny, cartwheeled, and broke his front bulkhead. He was done for the day. Repair cost? $40+.

That same day we broke an RC10T (rear A-arm mount - $2), an RC10 (old buggy - front wheel - $5), an electric MT (stripped spur gear - $4 - owner's fault, pinion gear wasn't loctited), and a Losi XXX-NT (bent fron axle stub - $3).

So yes, HPIs break, and so does everything else. WHAT breaks and how often and how hard repairs are is the real question in my opinion. MT a-arms break. I like that. They're easy to replace and they're cheap. Some people upgrade to aluminum, which is stronger, but then something else has to take the shock load, and it's something else that's harder to replace and possibly more expensive.

Remember the KISS principle.

That's my nickel's worth.

Does anyone have a list of sites where i can find bodies , rims . Or any other cool sites with parts. Towerhobbies only has some of the things i am looking for.

Also has anyone run the 2 speed tranny off road? how well built is it?

will any other truck rims fit the mt?

as i said before, www.hobbyetc.com go to the vehicle section on the left menu, go to HPI nitro (selecting from the pull-down menu, cause the thingies dont work if you just click on them) then select Nitro MT (once again, from the pull-down menu) and viola!! you have about 150 upgrade parts for the NMT...Wheels...i really dont use websites to buy wheels, I just buy them at "your local friendly hobby shop"
I have heard contradictory reports on the 2-speed tranny off-road. All the people on the HPI site forum said that the 2-speed breaks easily of-road, and a slipper clutch is a much better investment. Several people at the local hobby shop have NMT's too, and theirs have 2-speeds installed. They have never complained about it breaking, and they do run of road...how much more off road can you get than an abandoned construction site in the middle of the woods (dont ask)?

BrassMonkey I have had no problems with my Ti Buckles popping, I am using RPM Ballcups with HG Ti Ballends, although I try and avoid cartwheeling (but still do!) I have had no "Pop outs" yet. Finally the Graphite UD really stiffened up my NMT, I am real pleased with it (aside from more stuff to keep tight). Just my two cents!:D

I've got two pair of Pro-Line Mashers for my NMT. One set was new, one was used. Neither set came with foam inserts. New Masher 2000s come with foam.

I've got 2.2" tire foams, but they don't really fill the Mashers, and I can't find Masher-specific foam on the Web.

Do Mashers need foam inserts? If so, should I just run the regular 2.2" foams?

I am looking for a decent $150 engine that will pull out some decent horses and adequete torque for my nmt. Any ideas? I prefer rotary carb and need pullstart too.

I'm VERY impressed by the Orion Wasp engine, at least the .12 version. They also make .15s and .18s. Not sure on the prices, though.

Everyone gushes over the O.S. CV-RX engine, although I think they're a bit over $150. Fantoms can be had for $110. And so on.... :)

So far I'd have to agree with that, although I haven't had time to tune my low-speed needle and I still have the stock clutch. It really does rev though, it sounds like it revs higher than the Wasp .12, but who really knows?

Comparing the Fantom FR15 in my NMT to the Wasp .12 in my Losi XXX-NT isn't a very good comparison.

Hey guys,
Just one question:)
The age old question of tires. I want the softest, gripy-est, sticky-est, best-est tires there are. 2.2inch truck tires of course. life span is not an issue. please help. seeing as proline is about the only company that makes good tires, i was looking on their site and am thinking that the 'SPEED HAWGS 2.2 TRUCK PRO1080' are my best bet. anyone else have an opinion of onroad tires?

right now i am currently using bald M2 bowties on the road, and they are sick, LOL. after about 20secs they are red hot and hardly ever break traction, so if you guys cant recomend any good on-road tires, then i will prolly get some M3 bowties, wear them out in the dirt, then use them for on-road action. but i would prefer some proper on-road tires.

thanks,
Mad Man

Hey-

I am new to nitro R/C cars, and have been researching them for the past week or so. I am really interested in the RS4 MT and was wondering how intensive the matainance is. I've looked at the HPI website and their tutorials about matainance and it seems extremely thorough, is this how it is in real life?

Also, how often do you need to replace parts? If it is frequent, then maybe I should just buy a lot of parts when i purchase the car so that I will have them available.

Although I haven't totally decided on the RS4 MT, this is what I'm looking for.

- Recreational car (not for racing)
- Doesnt need to be really fast
- About $300 or less
- Able to run off and on road
- Fairly durable/reliable
- Easy to maintain

Thanks!

StealthPenguin, based on what you are looking for I would say that the NMT is just right for you! The 15 FE is very easy to tune and is quite a relieable engine (although it can run a little hot!) The NMT handles great both on and off road with little modifications. I would recommend to you that you get some spare A-Arms, they are on a "tree" that comes with some other handy spare parts, you may want to get some spare shock towers as well, the "trees" are relatively cheap and will keep you running instead of waiting for parts to come in. Remember to boil your A-Arms before running your truck, it allows the molecules in the plastic to "relax" a little bit allowing them to flex in a crash. Go for it the NMT rocks, you wont be dissapointed!

Check out my site, it might help sway your decision! :D

BRASSMONKEY, yes I am still selling bumpers for the NMT. They are very durable. They are 15 dollars a SET, shipping included! (in North America) The rear bumper prevents damage from rear impacts/landings and also acts as a carry handle. (I could actually send you two front bumpers instead of the front/rear set if you are interested) Me and my T-Maxx owning buddys did some experimenting with head on collisions at WOT about a dozen times at various angles of impact and there was no damage to my NMT or the bumper! After over a gallon of fuel they are only scratched up a little.
Flip me an email at mossdognmt@yahoo.com if you want some more information/specifications on the bumpers.

I finnally got the time to run my nmt today with the diffs packed with oil. It seems to me like the car is very very unstable at 25+ mph. The car drifts to the side too (left and right). I haven't had the time to run it off-road, but on-road, the car drift to the side and spins out a lot on slippery sufaces (sidewalk). Is this supposed to happen?

Mossdog
11-17-2002, 04:44 PM
Are your servos twitching? You may be getting interference or glitching, check all your electrical connections, I once had a similar problem and upon inspection found that I had a small cut in my antenna wire. Also make sure that your steering assembly is not loose and your wheelnuts are tight enough. The NMT normally handles excellent, if your trim and electrics/mechanics are good it should run a straight line from stand still to WOT. If you are running Mashers I would suggest a stronger steering servo as well, when I put on my Mashers the stock HPI servo had a hard time turning the mashers consistantly. After my first rebuild on my diffs (packed with grease) my NMT was a little sluggish until the grease worked itself in, but I had no handling problems. Hope you find the problem!

so, how many spare parts should i buy when i get this truck?

and which ones?

Mossdog
11-18-2002, 12:22 AM
I would recommend some spare glow plugs, a fuel filter, an aftermarket air filter. The stock plastic turnbuckles pop off very easily, aftermarket turnbuckles and ball cups are a good idea as well. As for spare plastic you should get the A-Arms for sure as well as a couple spare dogbones.

HPI part # A-arms A456 $5
Tower set A346 $7
Dogbones A554 comes in pairs $6

Buying stock replacement parts is really cheap and having spare parts is better than not driving when you do bust something!

Check HPI's website and hit the instructions link, you will find the entire manual for the NMT online there to get an idea where and what the formentioned parts are.

is it possible to just get metal parts instead?
wouldnt that make it much less prone to breaking?

also, i read that by replacing the bushings that come stock with ball bearings can help reliability and performance. is this true?

I am planning on running this both on and off road. Therefore, would it be advised to get another set of tires designed for the road?

First, the plastic parts aren't "prone" to breaking. They break easier than aluminum, but they're ultra cheap, aluminum is expensive. Also, aluminum doesn't flex. If it bends, it stays bent.

I prefer to leave the a-arms plastic. If you get aluminum a-arms (they are available), then they're so tough and rigid that the shock loads under impact are transferred to something else. First it'd be the arm pivot pins, so you upgrade to stainless steel or titanium. Okay, those are good, so the pin mount is next in line. Sure enough, available in aluminum. But what's after that? I'm not ever sure, actually. The chassis? Buy a 4mm chassis and then you start shearing off screw heads because there's absolutely no give or flex in the system. That's great in a real car because you don't hit stuff (hopefully), but in a 1:10 R/C car, you hit stuff. And land wrong.

So I prefer to control the weak point in the system. What's the best thing to be the weak point? Something that's cheap and easy to fix. Of those items I listed, the cheapest and easiest is the a-arms. Maybe $5 for an a-arm "parts tree" and you get two arms and some other minor parts.

I've broken two a-arms and one shock tower so far. Total repair cost was about $10. Cheap enough to carry spares with you so there's only about a half-hour of downtime at the most.


Yes, ball bearings are a worth investment, but the nitro MT RTR comes with full bearings, as does the NMT Racer.

Regarding tires, I'm no expert, but I've found the Dirt Hawgs to be the best tires for on- AND off-road use! If my on-road use was restricted to carpet or super-smooth raceways I might feel differently, but on my driveway and street and all the other places I drive, the Dirt Hawgs are top Dawg. I've got them on my other two R/C cars as well, as do my truck-driving friends. They're simply great all-around tires. One guy bought Dirt Hawgs to supplement the on-road tires that came with his electric MT and he never even uses the on-roads anymore, the Hawgs are better in all conditions.

I'm with Mossdog mostly, get the A-arm tree and the shock tower tree. That way you'll have enough parts to replace two a-arms, both shock towers, the a-arm mount things, and the body posts as well. Not that all that stuff is going to break, but those parts trees come with a lot of stuff.

I've never popped a stock plastic non-turnbuckle, and actually one was strong enough to pull a ball stud out of the rear shock tower in a bad accident. Keep titanium turnbuckles and RPM ball caps in mind, but I wouldn't get them yet.

I've also never lost a dogbone, but that kind of goes hand-in-hand with popping the turnbuckles (if you pop those links, the dogbones will probably fall out - sometimes they're tough to find).

I've been driving my recently-aquired Losi XXX-NT (nitro stadium truck) quite a bit for the past week, including some yesterday. After I broke it yesterday (when jumping over a split-rail fence, don't miss the ramp and hit the fence - bent axle stub), I got out the NMT.

WOW! What a difference! The Losi with a Wasp .12 engine is very quick off the line and in top speed and is a blast to drive, but it can't turn to save its life if I'm on the throttle at all. So I'm out warming up the NMT and I can't believe how nice it turns! It's glued to the road compared to the Losi. And after a couple blasts up and down the road I hit the brakes, right? It stops VERY quickly and straight! Weird, eh? ;) The Losi, with only rear brakes, spins around every time and doesn't stop too quickly. Sure, I could lighten up on the brakes a little and it'd stop straighter, but then it wouldn't stop very quickly. The NMT stops great! I can't wait to get my fiber disc in there and really put the clamps on!

And when jumping, it's MUCH easier to correct the pitch of the truck with 4WD rather than 2WD. I know that's obvious, but I had forgotten.

I'm a little disappointed with the soft bottom end performance of the Fantom engine, but I'll have to play with the clutch, flywheel, and maybe gear it down a little to get up and going faster. The midrange and top end performance is great!

Ahhhh, the NMT just feels good! And to think I was debating between a T-Maxx, RC10GT, Rustler, and NMT when I bought this thing. I definitely made the right choice!

T-Maxx - big power, very capable, cheaply made, expensive to fix, and VERY expensive to make reliable
RC10GT/XXX-NT - decent price, tough, can have good power, fun, very limited traction, very limited steering
Rustler - cheap, very fast, cheaply made, limited traction and steering
NMT - mid-price, relatively well-made, fast (with aftermarket engine), great traction, great steering, and a BLAST to drive!

Jeez, I'm wordy today.

Very well put doesgo! And yes I agree the NMT is better than the T-Maxx. 3 of my Pals have maxx's and they are always breaking down/breaking in crashes. One of em has a Fantom 15 in his and has tons of starting problems, but it does have lots of top end, and little low end grunt in the Maxx when he does get it running. We have sealed it all up for airleaks, and checked everything out, but its still a fussy engine.

Well, the price was right on the Fantom, I needed an engine, the FE was toast, and I had heard good things. Why is it that I hear about the problems AFTER I buy? :rolleyes: Oh well. So far I do like it, and I haven't had any starting problems when I do everything right, but I've only run about 10 tanks through it. I've been using a starter box, too, which makes life easier.

I've heard the Fantom rotary carbs suck (no pun intended). I've got an OS CV-RX that I can't use (cut crank), maybe I'll see if that carb will work on the Fantom if I have problems.

Wheelies in a stadium truck are lots of fun, but it does get old after a while. Having the power available to pull them is cool most of the time as well, but with 2WD it can be tough to control sometimes. I'm not knocking power, believe me! But sometimes you just want to GO, and can't.

As for the T-Maxx, I guess everyone's experience is different and it depends on how you use it. My bro-in-law has put about $400 into his over and above the initial purchase price to make it reliable. Well, we think it's reliable, last time he was out it broke in about 10 minutes. He's broken spur gears, broke his front bulkhead, and blew most of the caps off his shocks, among other things. Sure, the caps can go back on the shocks, but it's only a matter of time before they go again. Now he's got the Big Bore shocks, titanium this, aluminum that, etc. I've got a stock Losi XXX-NT that's been through FAR worse for far longer in the past couple bashing sessions than his Maxx and the Losi bent two front axle stubs. $6.

Again, I'm not here to argue with the toughness of this or that, I'm just sharing my experiences. My NMT hasn't been bulletproof either, but merely landing on all four wheels after a decent jump hasn't cost me $100 for special shocks and springs. :D

R/C rocks, any way you look at it.

Well the NMT has more mantainence than the RC10, but then again the NMT is 4WD(more moving parts).

As for buying parts right from the start, I don't think you should. It's always best to buy a truck and then decide on what you want to upgrade first. Aluminum A-arms are not a wise upgrade, as they still bend in a head on crash and cost $25 to replace instead of the $5 stock arms.

Your best bet would be to get the truck first, run it for a gallon or so, and then decide on what you want! Whatever truck you end up getting it'll be a load of fun!

Wow, they really broke down the pros and cons for you, didn't they? Sheesh.

The GT is a good, reliable, tough truck from what I understand. I'll know firsthand in a couple days. :)

The GT is more simple and possibly easier to work on. Also cheaper to buy, initially. Probably comes with a better engine out of the box, too. If you want 2WD, get the GT. If you want 4WD, get the HPI NMT.

If you get the NMT, I'd get an a-arm tree and a shock tower tree while you're at the store. Only another $10 or so, then you'll have the parts on hand. Breaking something cheap and easy to replace but being out of luck because the hobby store isn't open stinks!

I've got a Fantom FR15 in my NMT and it's weak on the bottom end. The rest of the drivetrain is stock, although my friend gave me a lightweight flywheel and I just bought the HPI racing clutch.

The flywheel seems obvious for quick revving. The top end speed is fine as is, and I'd sacrifice a little for more acceleration off the line, so would an 11-tooth clutchbell help that, rather than the stock 12-tooth? This also seems obvious and it typically works in 1:1 cars, but I want to make sure I'm not missing something obvious.

The racing clutch has the two semi-circle shoes with a wraparound spring, rather than the two quarter-circle shoes with those clip springs like the stock design. Will the standard setup of the racing clutch help me out or should I go ahead and use the 2nd or 3rd hole right off the bat?

Thanks in advance.

What doesgo said just reminded me of something. What are the holes in the racing clutch for anyway? I have the Racer kit so I assumed it was just kinda there when I built it.

The clutch shoes have three mounting holes for three different
adjustments.
-First set-up is mounted in the first hole in the clutch bell,
this allows the clutch to engage at low RPM's for smooth
acceleration.
-Second set-up is mounted in the second hole in the clutch bell,
then the excess clutch bell is removed (the first mounting hole is
cut off), this allows the clutch to engage at higher RPM's for more
bottom end.
-Third set-up is mounted in the third hole in the clutch bell,
then the excess clutch bell is removed (the second mounting hole is
cut off), this allows the clutch to engage at higher RPM's for even
more bottom end, and is good for high bite tracks.


Wow, I'm glad you asked. I guess I just answered my own question! I need more bottom end, "bite" is rarely a problem with a 4WD NMT, so I'll definitely start at least at the middle hole and probably end up at the third hole.

now that I'm sure that the NMT is the truck that I'm looking for... all I have to do is convince my parents to get it for me... = P. I'm thinking combination birthday & x-mas present... but I'll try to get it as soon as possible! = D

I found the NMT RTR online for only $300, but I will still call around to some hobby shops in san francisco. If the hobby shop can get it within $20-30 of the internet price, i will definitely buy it from there because then i can skip out on shipping cost and while im there i can buy some spare parts and get some advice. Also, HPI recommends that after every 2 gallons (100 hours of running time) that you have the engine looked at by a professional, so I can just take it back there since I already know the guy.

Eventually, aside from some upgrades (mossdogg recommended air filter, fuel filter, replacement turnbuckles (whatever those are)), I might get some $bling$bling$ stuff like custom body and wheels.

Also, right now im trying to convince my friend to get one too so we can race them = P. He is looking at the HPI Savage.

Stealth,

Have you ever had an R/C car before because some of the stuff that we tell you and don't know what they we're talking about are sort of elementary stuff in terms of RC cars. I'm not trying to discourage you from getting the NMT (great truck, I'm lovin' it) but if you haven't had an RC car before you may want to go to your LHS and see if you can use someone's NMT (if anyone there has one) before you spend $300.

Just my 2 cents.

-Matt

stealthpenguin
11-18-2002, 09:16 PM
Yes, this will be my first R/C.

Would you discourage me from buying the NMT because of my inexperience w/ R/C?

I have researched/bought many a product through forums and word of mouth.

So, as I said. If I can, I will buy the car from a LHS so that if I am displeased with it, I can probably return it (btw. what is the warranty on the NMT RTR?)

Plus, if I did know anyone with a NMT, I would definitely try theirs first. But, R/C cars are not that big of a trend/fad in my town.

I've got an O.S. CV-RX .15 engine that's had its crank cut to work in a stadium truck (I believe). Is there any way to make that work in my NMT? Looking at that engine compared to my FE, it seems as though the distance from the edge of the engine block to the flywheel is rather significant in my NMT and it's not very far at all in a stadium truck.

Does anyone know if someone makes an adapter or fitting or something to bring the crank back to its "full glory"? :D

My brother bought an NMT RTR two years ago. He got used to the speed of the stock 15FE and soon wanted more. He reasoned that a OS 21RG could be made to fit. After reading on the Internet that people have done just that (install a .21 engine in a NMT) he decided to do it. He bought the engine, OFNA engine mounts and SG shaft flywheel/clutch kits (sorry, forgot all the part numbers). He also bought a CVEC .21 header and a cheap .21 pipe. When he was tuning the engine for power, after an extensive 10 tank break-in procedure, the breakages started. First the dogbones started to twist badly, then he upgraded to MIP CVD's. Then the diffs stripped, so he rebuilt both diffs with the expensive HD ones. Then the diff bevel gears (AKA spider gears) stripped, so he found a way to build them that would last longer. Then the diff outdrives would snap, so he replaced them with the "HD" ones. Then the CVD bones would snap, so he replaced them (only thing he could do). Then he decided to get the slipper clutch to soften the blow from the .21 engine. The slipper clutch would get so hot that the spur gear would melt right off! That was with the adjusting nut just about locked down! Then he converted back to the standard fixed 52T spur gear and the CVD's and the outdrives would start snapping like twigs.

On his twentieth tank after the breakages started, he finally got to run one full tank (at 75cc, it went pretty fast with a thirsty .21 sucking at the other end of the straw!) without breaking anything! That was an exception to the rule. He finally got fed up with it after we went out to drive our trucks (my NMT Racer running a 15CV-X Hyper at the time) and he broke a CVD not five minutes after we got started. He got to watch me drive my truck for another three tanks until I felt guilty and we packed up and headed home. He repaired his CVD while I cleaned my NMT and he drove it on my lawn for a shake-down and snapped an outdrive not two minutes into it. That NMT now has a 12CV-X Hyper in it with a heavy duty drivetrain.

Did I just inadvertently basically define the difference between a "standard" crank and an "SG" crank? If so, to rephrase my question, is there a way to make a standard crank work in an application that requires an SG crank?

I've got a Fantom in my NMT and I like it, but I'd also like to try the Wasp .12, OS CV-R .12, and OS CV-RX .15 that I have on hand in it as well to see what I like best.

I got the aluminum steering from Powerline and I put it in. When I went to put the front center dogbone in I foudn that it rubs on the new steering thing. I could have done it wrong but has anyone else come across this problem?

-Matt

doesgo
11-19-2002, 12:45 PM
What's the advantage of that Powerline aluminum steering deal? Smoother? It's got bearings, right? So it's more rigid and smoother for better and quicker steering response?

M16-A2
11-19-2002, 12:53 PM
The Powerline assembly does rub a little, but if you use it for a tank or two the doggie will notch grooves into the steering arm and move freely.(if you don't mind running with a little rubbing for a tank or two)

As for the advantages, the aluminum steering takes away almost all the play in the steering system. It really helps for straight line accuracy, and can hold a truer turn in the corners. One disadvantage is that you'll probably want a servo with more torque when you go to aluminum steering(if you haven't upgraded your servos already).

Well it's snowing here again, I have to go plow the driveway:(
Oh and when I get back I'll be putting a rollcage on ebay:)

You'll be fine as long as you read every instruction manual and make sure you know how everything works before you take it out. If you don't read the manuals you'll be coming on here asking all kinds of dumb questions(which I won't answer, because you should of read the manual).

In all honesty though, you'll be fine! Just take your time and ease into everything. It would help if you had a guy at your LHS to give you pointers, but if not come here for help.

11-19-2002, 02:25 PM
I would say then that you didn't install it correctly. It's a little tricky since they don't include directions, but I'd take it apart and reassemble it. If I have time I'll take mine apart and show you how it goes, but I doubt I have the time today.

Do you buy your parts online? or from a LHS?

I'll be sure to flip you an order when I get some money. I dunno, the nmt just flat out seems scetchy and unstable, at high speeds the car still drifts to one side. I don't run mashers, but I do have a high torque steering servo.
:mad: :mad: :mad: I seriously don't know what to do about this, there seems to be no electrical problems. My only guess is that the o-rings are putting out differnet amounts of friction on differnent sides of the car. Have you guys experenced this?

I was making my daily spur gears today, when all of a sudden my Dremel snapped (electrical snap!) and smoke came pouring out of the induction!

The snap has left my arm in a bit of a weakened state (it's a really wierd feeling). However it did give me an excuse to go buy the Multipro Variable Speed Dremel, as my old one was just a 2-speed.

Anyway...
I like to run ODonnell's 20% fuel, it offers excellent cooling and delivers power too! I used to run Blue Thunder but could never keep a good temp with that fuel, so I switched to OD and never looked back.

Thanks for relaying your experience with the HPI shocks, I'll be sure NOT to replace them or refill them when they go, I'll move right over to something better.

Way to go Stealthpenguin, you will really enjoy your NMT! I sure do! And ya there is more here than just pimping customized parts! I have the powerline shocks with the yellow springs. They are very stiff although not very reliable (the caps can only be turned down so far or the bladders pop in, and I keep blowing a E-Clip off the shock piston on one of my front shocks-guess 15 foot jumps will do that sometimes! :) , and I like em for extreme jumping/street running. I use my HPI blue springs for when I am off road running and vary my shock oil from 35 WT to 50WT depending on what I am doing with my NMT that day. I have not yet raced my NMT officially but 5 of my pals have Nitro trucks and my NMT kicks their butts when we do set up a homemade track!

And always remember.....

11-21-2002, 02:02 PM
I race my NMT at a local track(next season I will have the local track :)) and I have not lost as of yet. Given that the competition here is mostly 12-14 year olds, and most can't afford many hop-ups, so winning all the time is a pretty easy thing.

We group all Nitro Trucks into one category, so we get about 10-15 trucks each week. Whether its a Tmaxx, NMT, or 10GT it all races in the Nitro Truck category.(there aren't many RC'ers here)

Shock oil is included in the kit, as well as oil for your air filter.

You could buy diff oil, but it's not at all necessary.

Then there is after-run oil which should be used in your engine if the engine will be sitting for more than a couple of days.

Well at least you have some. I have yet to find people in my area who RC. And to find a track to race. If anyone here lives in MD, tell me, maybe you know of a track.

On the steering thing...

The steering comes with little aluminum cylinders that go on the posts. Well the first time I assembled the steering I had it on the bottom, but now I have it on top. I don't know which way it's "supposed" to be but this way works for me.

I'm having a problem with my shocks. Every time I fill them up, then go out and run it, I come inside to find that the oil has oozed (ha ha, oozed) out. I always make sure everything is tight but it still happens. You think I need to get new shocks?

And I have a dilema...

After that dremel shorted and shocked me yesterday I didn't think too much of it, there wasn't much pain and I seemed to be able to move my arm and fingers just fine.

...Well today my arm is turning this nice shade of blue! My fingers have some limited motion to them, and if I do move them far it hurts all the way up my arm:(

Needless to say I'm typing with one arm tonight, and I think a trip to the doctor is in order for tomorrow...

OK that's my rant for the day, just had to get it off my chest!

Hey, I was wondering. I read that these cars will run about 5-10 min. on a full tank. Is it possible to upgrade the fuel tank so it could run like twice as long?

M16-A2
11-22-2002, 01:03 PM
10-15 minutes is a better estimate as to how long it'll run. If you only get 5 minutes you have problems in your fuel delivery, exhaust, or engine.

There is an pretty easy way to mount a second gas tank to your truck. You can easily fashion some L-mounts to put a tank on the rear shock tower!

The startup kit im getting comes with 1 quart of fuel, how long will that last me?

doesgo
11-22-2002, 07:27 PM
Well, with no waste, your tank is 75cc, a quart is 946cc, so that's 12-13 tanks. You'll go through about six during the break-in, so it won't last too long.

But "they" say to only buy enough to last a month or so (it absorbs water), so I'd probably buy two quarts and make sure you use up the first one before opening the second one.

gometro333
11-22-2002, 07:32 PM
For the first part of the break-in process my engine sucked up fuel. But now I can get pretty good run times with it. I used about a gallon in a week when I got my NMT. But thats just me.

-Matt

11-22-2002, 08:02 PM
WOW!!!! Did you ever sleep? I've finally gone through a gallon now and it took me two months! Then again, I was working a lot, and playing with a XXX-NT and RC10GT....

gometro333
11-22-2002, 08:15 PM
Well I got it during spring break two years ago so I had plenty of free time. I pretty much broke-in the engine in a day. But you shoulda seen me, I was hypnotized. But I was in awe when I saw how much power and speed it had compared to my other electic cars. After about a half gallon I was just having drag races with myself up and down the street. Then I took it off-road and into my woods. I launched off so many rocks and hit so many trees but I didn't once break anything. I was in shock at the strength of it. I could do anything to it and it wouldn't break. So I thought that all nitro cars would be like this. Then after running my friends T-Maxx and seeing him run it, I realized that it was just the NMT that could take any abuse that I through at it. In one day my friend did over a $100 in damage to his T-Maxx just doing the exact same thing as me. Infact we were playing follow the leader (a great game to practice making sudden direction changes, like in a pile up on the track) and he couldn't keep up to me. Sure I have a 15ss but he had his 2-speed going and still couldn't catch me. But the real test came when we went to the house next door that was getting renovated. The workers had a HUGE pile of dirt in the back, and they had no problem with us using it (plus I think they wanted something to do). Well in the climb I crushed the T-Maxx. Infact it was so steep that the Maxx actually flipped over backwards. But my NMT, with a little zig zagging, got on top. But to this day my friends insists that the T-Maxx in the best car ever. But I keep on telling him it's the NMT.

Just thought I would share the story of the early moments of my NMT.

what a great testimonial...

as for me, im planning on getting 2 quarts of duratraxx's red-alert 20% fuel. Unfortunately, they dont sell 1 gallon containers, only 4 gal. and 1 quart.

Lanc3r
11-23-2002, 09:43 AM
Getting a lot of fuel at once isn't really that great...the fuel will soak up water, and become less explosive i.e. less effective. If you are planning to get a lot of fuel at once, maybe on sale or something, get the fuel in the metal canisters. They don't allow a lot of water through, unlike the plastic soft cans. oh, and get a heavy-duty steering servo. They help a lot when it comes to tracking straight, and cornering, and it is indespensable in racing. You dont need to get it right away, but it should be a part of your hop-up plan.

When you buy fuel just make sure to store it in a dry area, and keep the seal on tight. Yes nitro fuel is hydroscopic, but it won't automatically suck up all the water in the air.

I buy about 2 gallons of fuel a month for my RC, and just store it in the closet in my room. Of course I only open one quart at a time.

In the past I have stored nitro for a year with absolutely no problems, it all depends in how and where you store it.

Is there anything I could say to put my dad's mind at ease?

Also, where would be a good place to store it? I was thinking about putting it in a plastic container (like a Roughneck) underneath the awning on our back deck.

PCC, about getting one used. My mom is really uptight about buying used stuff (although I do it all the time), but I think I rather just get it from Towerhobbies to be safe and so I can return it if anything very serious is defective.

I have been running Red Alert 20 in my Ofna Hyper 21 engine and it works really well. I am purchasing a OS MG 2034 .15 (is that right?) for my NMT. Any comments? I am pretty excited because the engine will be here this week and I have a 4-day weekend. I want to make sure the installation goes good, break-in is no problem but I have never installed a nitro engine in a new car. Also, the NMT seems a little tight (the diffs and suspension) is this normal? I assembled it late into the night and I think maybe it is too tight...

The nitro used in RC fuel doesn't actually explode even when ignited. If you've ever had a glow plug off your engine and connected it to an ignitor, then put a little nitro on it you'll notice there is no explosion, it just burns up and sizzles.
I've stored nitro in my house for years now, and nothings been blown up or burnt... YET! (just kidding)

gometro333
11-24-2002, 02:36 PM
Well you could just tell him that if it ever did catch on fire he wouldn't see it because it burns with an invisible flame. I had a nasty experience with the whole invisible flame thing. It had to to with a low flying bird and spilling nitro, I don't want to get into it.

BUT TO BE SERIOUS...

It doesn't burn any hotter than wood does so if you had a fire in your house you would be screwed anyway so you shouldn't fret about it.

I'm throwing together some Christmas gift ideas and naturally parts for my NMT are at the top of the list. I'm a basher - driveway, street, yard, BMX track, whatever.

I already own HPI SS hinge pins, HPI fiber brake disk, lightweight flywheel, Fantom FR15 engine, and HPI racing clutch.

Is the Powerline 4mm chassis a worthwhile upgrade at $34 or is it overkill? The 2.5mm HPI chassis is about the same price. How about the HPI graphite upper deck at $35? I've got titanium turnbuckles on the list, as well as a new body, slipper clutch, gear diff spring set, and diff oil.

Any other suggestions?

We found this sweet jump at the farm, there was a natural ramp on a hillside. So we played this game where we picked a spot on the ground and then saw who could jump there truck closest to that mark.

Most of the spots we picked at first were around 8-15 feet from the jump, and he beat me in 14 out of 20 jumps! So after the first 19 jumps I picked a spot about 30 feet from the jump, fully knowing he'd never be able to get to that mark! (although he still beat me in accuracy, I wasn't too happy):mad:

Oh well at least I have the speed and distance thing, I'll give him accuracy for now!:p

I emailed them when the listing DID change, and got a response on it. So now im just buying the whole package from Towerhobbies.com . As for the fuel thing, do you think its alright if I store it outdoors, like in a roughneck container?

dcshoelover
11-25-2002, 01:18 AM
OK, glad that's cleared up. Best bet is to buy a brand of fuel that's in a tin container. When you buy it in a plastic jug, it gathers moisture inside the jug which dilutes the fuel and basically ruins it, and 2, you have to store it inside during winter so the cold can't ruin it, which is highly not recommended, and here's why. I sotred my fuel in my room, and last november my lamp shorted or somethin, still not sure what happened exactly, and started my room on fire. Well having a plastic jug of fuel nearby didn't help. The plastic melted and the fuel increased the fire by like 10 times the size. I lost 2 cats and a dog and justa bout every one of my possesions, except a nitro rustler somehow. So I highly recommend buying tin jug that you can store in your basement or in your garage if it doesn't get to cold.

stealthpenguin

Where can I buy nitro fuel in metal containers? Unfortunately Towerhobbies.com doesnt carry them = (. However, would it be fine if the nitro fuel was in a plastic container, but in a dry place? I know that it can absorb water, but is that only in very cold/moist conditions? I live in Northern California, and it doesn't get that cold here. So maybe I could just put it in the garage or something like that?

If I'm just gonna be messing around mostly, would you recommend 10% or 20% nitro? Also, although it isnt listed on their site, can I specify that I want the fuel in metal containers? Is it that big of a difference if its not exposed to any extreme conditions?

M16-A2
11-25-2002, 01:38 PM
Storing fuel in metal containers is not necessary at all! As long as the fuel is stored in a dry place(like a closet in your house), then there will be no problem buying plastic fuel bottles.

As for nitro percentage you'll probably want 20%, as it allows for more power than 10% and still gives you many gallons of engine life!

RC10GT is a great racing truck, no question about it. Tough, can be quick, easy to work on, lots of parts out there.

NMT is a great truck overall. Tough, can be quick, easy to work on, lots of parts out there, and 4WD!

I've had two trips to a BMX track recently. The first one I ran my NMT and also my Team Losi XXX-NT. The XXX-NT was really tough and fast, but spun out all over the place and it can't steer very well when accelerating because the front end gets so light. Yeah, there are things you can do with the clutch and suspension and weights and stuff to make it better, but I found my NMT to be much more fun overall.

The next week I did the same thing with my NMT and my RC10GT. Similar result. The GT had a looser clutch than the Losi did so it was a little easier to control (and it has a CV-R instead of the Wasp in the Losi) but still it was not nearly as much fun as the NMT.

For bashing, I think 4WD makes life fun, and I'm selling my Losi and my GT and keeping my NMT! :D

Asking how to store fuel isn't a "legitimate question"? Everyone was a newbie at some point, even you. That's the point of the forum.

How much are you looking to spend on an engine? From what I've read and from my little experience, the best mid-priced engine for an NMT would be an OS CV-RX 15. Great power, long-lasting, easy to tune. I think they run about $170.

There are tons of other engines of course, from $80 and up. It does seem like you get what you pay for.

Stock settings are near 3 turns low and 2-2.5 high, the OS website should have exact settings if you look.

For ball studs I'd highly recommend getting Ti studs, as they never break!

Anyone know the torque of the stock steering servo in an NMT? I think it's the "SX1", I assume it's made by Airtronics, but I can't find info on it in the HPI site.

I've got a couple JR Racing Z550 servos on hand that have (I think) .15 transit time and .62 in/oz, would they be worth installing or would that be such a minor improvement over stock so as not to be worth my time?

M16-A2
11-26-2002, 07:23 PM
The radio that comes with the NMT is an Airtronics, so the stock servos would be 94102Z (Z is just the type of connector).

Stats are:
.22 transit for 60 degrees
50 oz/in.

BTW, I noticed you put .62 in/oz. Could you please do the conversion for me and switch that to oz/in.:D (I know what you meant)

There was sort of a push in the 1:1 hot rod scene to start using pound-feet instead of foot-pounds for torque values because it was the accurate way to represent it. People resisted, and most people say foot-pounds again.

Okay, so how about the Z550 puts out .0075 pound-feet? :p

uh-oh the tread is dying....

So anyway list of hop-ups this Christmas:

O.S. cv-rx (hopefully)
adjustable slipper clutch
masher 2ks

That's pretty much it. I don't like wasting my parent's money, I know the value of a dollar. Let me know if I should replace or add anything (Will the O.S. tear up the drive train?), it cant be super expensive, I want to keep cost DOWN. Thanks.

The drivetrain should hold up well with the O.S.
I've just ordered
Ti ball studs
Ti turnbuckles
and replacenent arms and gearboxes

also, will this flywheel fit the 15 CV in my NMT?

is that fly wheel bigger or smaller than stock, and either way will I have to change the engaging point on my starter box?

That's smaller than a stock pull-start flywheel. I doubt you'll be able to use it with a pull-start engine since the pullstart mounts are higher than non-pull-start mounts. The starter wheel won't be able to get high enough in the chassis to contact the flywheel.

How about the HPI lightweight flywheel? Cheap, lighter than stock, and it'll work with a starter box and pull-start engine.

cool, thanks
this may sound like a dumb question to you guys, but
what are the advantages of an aluminum flywheel over a cast one?

M16-A2
11-28-2002, 09:33 AM
That flywheel is 32mm, which means you need 15mm(or non-pullstart) engine mounts for it to work. If you want a flywheel for pullstart engine mounts, HPI makes a lightweight wheel.

The advantages to this type of lightened wheel is that it allows the engine to spool much faster and gets you up through the powerband faster than a heavier flywheel would.

doesgo
11-28-2002, 11:38 AM
Just to clarify, if you have a pull-starter, you can't use the non-pull-start mounts.

I believe all flywheels are cast aluminum (the ones I've seen, at least). Lightweight flywheels are typically thinner or smaller in diameter or have lightening holes drilled in them.

As far as I can tell, the slipper clutch cannot handle more than about 1HP well. More than that and the thing gets so hot that the plastic spur gear just melts off the mount (I've seen this happen myself but it was because of the 21RG's greater torque). Others have reported that engines, like the Evo II and MT12, will melt the spur, too. Clamping down the slipper helps but then it defeats the whole purpose of the slipper clutch.

I was wondering about that same thing. I have run my NMT without a slipper since I got it. I do bend dogbones in the front quite a bit while jumping and bashing but so far my rear CVDS are doing great! I have not yet stipped a spur. Soon I am upgrading my engine and was contemplating a slipper as well. Maybe I should spend that cash on front CVDS instead. No use in buying a slipper to just tighten it right up, wont protect the drivetrain anyways.

I know back when HPI's forum was up there was a guy that used to post Tower Codes.

They saved you money on shipping and off the total amounts of the purchase,

i was thinking about getting a mt for christmas, i have a t-maxx and a e-maxx now, but i thought about setting a mt up for street/dirt. is the mt racer worth the extra money? i saw the mt is now updated but not the racer. will a traxxas 2.5 engine fit the mt? anyone try this? thanks

doesgo
11-29-2002, 12:08 PM
If I could do it over again, I'd get the MT Racer. I don't care for the stock engine in the NMT and if you're going to replace it rather soon anyway, why not get the Racer and a nice aftermarket engine and enjoy the upgrades that come with the Racer?

I destroyed my first spur gear in my NMT yesterday. I was just bashing in the driveway/yard/street, not doing anything out of the ordinary, and suddenly it sounded funny. About half the teeth are gone now.

My question is, what are the possible causes for this to happen so I can try to avoid it in the future? I've got a Fantom FR15 engine, 11-tooth bell, and no slipper.

1) Landing a jump with too many rpm (no jumping yesterday)
2) Gear mesh (I checked that with a doubled-over piece of paper)
3) Too much power (I wish!)
What else?

Thanks.

M16-A2
11-29-2002, 12:15 PM
Engine vibration can loosen the engine mount screws and mess up your gear mesh. Make sure all metal to metal screws are secured with loctite. A slipper will help greatly in preventing gears from stripping, so would a larger clutchbell(would take some of that low end power away).

Of course landing a large jump puts a lot of stress on the drivetrain and could even cause a little chassis flex which would lead to a stripped spur.

Does someone make a skid that covers the spur gear it seems to hang low and jumping i am buttoming out a little.

M16-A2

There is a lexan cover included with every body...
If you need to make one just get a 2-liter soda bottle and cut it to fit, then put the screws through it.

i asked that question about 4 pages ago and got a additude racers should have there own thread. i race my nmt,mbx ofna and hpi micro on carpet and a 1/12 scale carpet knife. every thursday offroad some special races on the weekends in the summer now is indoor carpet races ovals and road course i would say i am a racer but these don't seem to be .........

I race at the local track(next season I'll own the local track:)), but there hasn't been a lot of competition here lately. This season I ended on a 24+ week winning streak. Competition around here consists of 3-4 Maxx's, 2-3 N-Rustlers, a Rush, and my brothers NMT.

Most of the kids that own these trucks are just out for fun(as I am too), but they don't compete well when thrown onto a closed track. Oh well the important thing is everybody has a good time and I get to teach some of the newer RC/ers some tricks and tips!

On a good night of offroad racing there is about ten t-maxs and my mt, other classes are 1/8 buggy about 20 of us,2wd. nitro stadium trucks losi,rush,rc-10 etc. and electric stock trucks and electric mod trucks. The stock electric trucks are usually young kids my 5 year old son drives in that class. We will have 3 heat races and the main usually ends about 11:00 at night every thursday. Believe it the fast lap times come from electric mod trucks all the time.

Clod_Killer
11-29-2002, 10:47 PM
Thanks guys, thats what I wanted to know. Here, they race 2wd and 4wd stadium together. Its indoor dirt (Big exhaust fans) and they figure the gain the 4wd's have is picked up by the speed of the lighter 2wd tracks, since its hard pack and traction isn't a problem. I know most people use them for play, didn't know if anyone wanted to talk setups and such for the track. I would love to see the class take off. I think 4wd stadium is the most fun.

Oh, I am working on a set of Carbon Fiber shock towers for the truck as well, that allows for a lot more adjustments.

hi, im new to this sorry if this is a repeat question. i wanted the most recent info. what are a few good engines for the mt racer. i will be racing so they have to be .12 size. what about crank size i dont want to have to cut it(not sure what size is needed for the mt kit) thank you for your help.

Clod_Killer
11-30-2002, 10:06 AM
The blue head Picco's, RB's, Nova Rossi's, OS. CV-R, etc. If you have to stick with .12 class, get the best you can afford.

Is there anything wrong with switching brands of fuel in an engine? I've got half a gallon of Blue Thunder run through my engine, but I've got half a gallon of Trinity Monster Fuel with no place to go. Same nitro content, same oil content. Any problems with that?

KOLOR KRAFT
11-30-2002, 11:02 AM
I WILL SAY IT AGAIN before you make the purchase check the specs on CRC website which is frank calandra racing here in rome,ny he is the only importer for STS highly modified .12 but legal just plain rips i think its 5 port and 3 but you need a starter box. i race with them on thursday and its hard to catch them on the back stretch and i have os 15cv-rx that i thought really ripped . christmas is coming i think my wife got me the STS motor so now i have two choices to race . now if i find another mt cheap i will be all set this summer.............

KOLOR KRAFT

not a good idea to switch fuels you already been running in a motor due to DIFERENT kinds of oils used try to stick with the same fuel with the same piston and sleeve.

mmmmmmm, look at this picco: p15 .15 pull start picco exahast (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=lxrt74&p=7) Do you think it will fit? It's ten dollars cheaper than the CV-RX too. $10 off with that code. Comes out to $159 not too bad :cool:

The Nitro MT goes 32 bone stock, as to w/ the 2 speed, I have no idea. M-16 A2 has a 2 speed, I think, ask him.

M16-A2
11-30-2002, 11:32 PM
I don't have a 2-speed, but if I gear at 18/49 I've been clocked at 54mph(RB Concepts X12 as a powerplant).

when i let my buddy from work borrow my truck, he tried to bump-start it with a dremel tool that had a buffing wheel on it. (I'm still kicking myself)
anyway, he wore a flat spot in the flywheel. should i not run it until I get a new flywheel, or is it all right for a few tanks.
it's barely noticable, but I can tell it's there

What brand of batteries should I buy?

Hey guys iam getting a Hpi Nmt racer kit. It has this stuff on it (Powerline aluminum front lower suspension mount, titanium front shock tower, HD diffs in the rear) So can any body else recomend any other hopups for it and also can you send me some links of companys that make hopups for it? Thanks!

I'd just start out with 12 regular ol' AA batteries from Energizer or Duracell, but make sure you keep the receiver batteries fresh to avoid a runaway. When you can afford it, get a NiCad or NiMh 5-cell receiver pack, but to charge it you'll need a charger that can charge at a 1-amp rate (I believe that's what's recommended).

You can also get rechargeable radio batteries, just rechargeable AAs, and there should be a charge jack in the radio for charging them, but I'm not sure what you need to buy, specifically.

So M16, I need all of these things to power the radio?
How long will the batteries last?
What amp rate is recommended (according to doesgo its 1)
I already have some NiMh batteries and a 4 batt. charger, can I use this? Or should I get one with a greater capacity?

Man, the cost on this R/C is really adding up... over $400 just to get started.

doesgo
12-01-2002, 08:50 PM
$5 worth of AAs will get you started, Stealth, you can work your way up to the rechargeables. I'd get the regular dry cell AAs and a small spring from the hardware store to serve as a throttle-return spring in case the batteries wear out and you don't notice. It's a low-tech, poor-man's failsafe.

When you get some money, get a failsafe and a 5-cell rechargeable receiver pack. The 8 AAs in the transmitter last quite a while.

M16-A2
12-01-2002, 08:50 PM
Tx = transmitter
Rx = reciever
The charger is just an easy all in one charger that I've found is very easy to use.
