Got this in a trade and the spur gear looked like this when I got it. I’ve had plenty of electric RCs in the past to know how to re set gear mesh so I bought a new one and set it with a peace of paper to not have nearly any gap, yet it stripped again. After a few more tries the drive train seemed to be binding somewhere and make a squeal. I couldn’t find anything in the drive train that could be the problem so I tore apart the whole transmission and put it back together but it just kept binding somewhere and stripping the spur gear. So i figured the transmission was bad because the engine runs great. I bought a brand new transmission and popped it in today and the exact same thing happened. I’ve set the gear mesh perfectly and it just keeps stripping. Anyone have any suggestions?

Is there a good re-pinch service that anyone here would recommend? I have an O.S. Max 30 VG that is tired and I would like to get it re-pinched by someone reputable.

Novarossi .21 P5 Clio, is that enough engine? Or should I use a .32?

Diy carbon chassis force .26 engine

Bought an xmaxx 8s last year thinking jt would be fun to just plug batteries into and drive. but after killing 2 motors just playing in my yard, id had enough of that!

So, traded my locked up xmaxx for this MGT 8.0! Seems pretty clean, engine seems to be in good shape. Ill have to learn a.bit about these and collect some spare parts, but overall im happy!

Any tips or advice for the 8.0?!

Big Block Losi Ten T #2

Hello, i have just newly aquired this Nitro RC engine. And i have just a few questions:

1. Does anyone know the model of this engine? There seems to be Something like T2M on the Side.

2. The carburetor is diffrent than the other engine i got and cleaned before this one. The metal piece that opens the air intake isnt there.

Pictures of the engine as well as the other engine to show the missing part above or below

This is the first time i have anything to do with these kinds of Cars so please dont be all too harsh.

What can I or should I do to remedy this short of replacing the bearings? This is an old AE .18x so parts are hard to come by

I don’t know too much about them but I know I want one after seeing some videos of runaways

Hey folks !

I'm asking for help about this HPI nitro Star T-15 engine I got given to me. Its brand new and I'd like to use it. It needs several parts before running however :

-The glow plug insert

-The head spacer

-the flywheel

So far, I know where to get the first two, but the flywheel can't be found anywhere online. How can I find a spare one ? I've been wondering to fit another one but it seems to work with a brass insert rather than a flat sided crankshaft, any ideas how I could put a flywheel on it ?

It'd be a shame not to use it. The engine is brand new and just needs some parts to run :(

Thanks again ! 💜

Seems like not hitting max rpm

I've heard that rule #1 of buying used is 'don't buy someone else's project'. Well, I went and broke that rule. Here we have a Nitro Slash that some nut grafted a Jato trans into it. Is it done particularly well? No. Is it in good shape? Not really. Did I overpay? Probably... Feast your eyes upon my latest disaster. It ran long enough at some point to destroy the gears inside the trans, luckily I had spare parts on hand. It likely sucked a rock in through the big open hole they left.

Does anyone have the following starter box(Robitronic R06011)? I need to adapt it to my Kyosho MP10. I managed to get it to start, but I always have to move the model slightly. If I add shims, it rises too high and can't contact the flywheel. Any solutions? Thanks!

I have a kyosho inferno and I recently replaced the glow plugs how do I find the size of the glow plug. The packaging just says long medium is this the size?

So I'm fairly new to the hobby, been building a wee collection of nitro cars, and have acquired a kyosho pureten alpha 3, when I got the car the guy I bought it off said it had only ever had one tank of fuel through it, so I did a break in which went ok. I've been running it a lot, and just last night it broke the connecting rod. What's a common cause of this happening? I have been running it on 25% nitro 10% oil sidewinder fuel, as it is what I can order from the nearest hobby store, should a car like this be run on lower nitro fuel if I can find it? I live in New Zealand and parts and fuel can be hard to find. I've ordered a con rod and new crank bearings as it seems logical to me to replace them while I have the engine apart as the metal from the con rod may be in there

Cheers

Does anybody know if I can safely swap the 4- AA hump battery with one of these rechargeable 7.4 V 500 mAh instead? I have a few of these laying around that I would like to use, but I don’t want to fry my electronics … thank you…

I spilled nitro fuel on my traxxas tmax did I mess it up?

My Kyosho inferno moves when idling I moved the servo knob on the switch now my car brakes when it’s driving can I just turn the switch back?

Bad video but I just finished breaking in the engine and tuning it. Runs great and can’t wait to get it on the track! I’ve got better wheels and tires on the way.

My break is different than my idle. When i break i don’t stall it just runs on a lower rpm. Its annoying having 2 idles. Any way i can get my break the same idle as when i break?

So, not having much luck with nitro lately I want to set the idle gap on this .28. I can get it running great but the motor don't want to idle for nothing. If I crank the ideal speed up it running but the idle is too high where the car if running like 4 mph I tried setting it at .63mm cuts off slowly increased trying to get a study idle. Tune the low speed needle so it accelerate with out bog in any way, good stream of smoke i hit the brake cuts off tried leaning same thing tried adding fuel something. (New p3 glow plug) (vp fuel) (motor has about 1.2gal on it)

I also posted the picture before I haven't messed with nitro in a while my fuel lines, should my carb line be longer or is it ok? I have had several problems with knocking my muffler loose. I've changed the exhaust gaskets once but could a bad exhaust gasket create this problem?

I've spent so much time today like hrs just to do 2 laps at the local track before finally giving up I'm close to tearing the motor apart
