Hey guys,
i have a HPI NITRO MT2 and i have noticed some problems lately that i know nothing about and need your help with..

okay so first off... i noticed that after i had the car apart last summer to clean it throughly it would not turn as tight

second, when i ran it last summer about two or three months ago... i was running it not hard but not soft.... it was getting ran pretty good.... and after about ten minutes.... after a five minute warm up and then running it pretty good for ten minutes... i noticed that it would not move!!! almost like the clutch bell had enough and decided to go night night... but it was replaced with all new parts, the whole cluthch bell housing and all the components inside of it... and the spur gear was replaced that day and everything was replaced at the local hobby shop.. Hobbytown USA.. so thats the second problem

third, i was just wondering if anyone knew about a racing league for that type of truck in washington...

if you could please email me with some answers that would be great!!!!

I've never owned that truck, so I can't say what's wrong with it.

I would suggest you obtain the manual for your truck and disassemble the truck yourself, in steps. Not only will you familiarize yourself with the truck, but when something goes wrong, you'll know exactly what it is and won't have to go to the lhs for repairs, but rather just for the parts.

It sounds like the pilot shaft nut has come loose. This is the nut that secures the fly wheel to the engine crank shaft. Check this by turning the fly wheel by hand, it should be very difficult to turn as the piston approaches top dead center(compression/pinch force). As for the truck not turning as tight, (1)Check to insure the front wheels are moving from stop to stop with your transmitter steering wheel. (2) Check the rear differential, as you hold the center drive shaft and turn one wheel the other wheel should turn in the opposite direction. (3) Your getting faster and experiencing steering "push" as you go through turns.

Disassemble the parts you replaced and see if you tightened and relubed it properly. Do you still have your manuel for the truck?

Have you tried talking with your local hobby shop?

They will have some great ideas and may help you fix your car also.

Second, they should also know of any local tracks in the area.
