Default need help with traxxas 4 tec

i got this car not long ago and it ran perfectly, until i crashed it. now it will start up, and runs great for about 2 minutes, then i hear a click and the motor just dies. it will not start again after that, but after about 10 minutes it will start again. any ideas as to what might be going on? i dont think its over heating, and it is tuned well. it runs very strong when it does run. please let me know what you guys think. thanks alot!!!!!!!!!!!!

Need a little more info...when it 'clicks', does the engine sputter then dies or does it quit suddenly? Does it lose power just before it dies? Need to know a little bit more of the symptoms...

no it doesnt lose power, its running great then you hear a click and the motor dies instantly, and the car will coast to a stop. no sputtering at all. hope this is enough info for you. thansk for the help.

It doesn't sound like a bent crank. I could be your clutch or 2 speed making it happen. Sounds like somthing is catching, making the clicking sound, which is stopping the engine. You are going to have to start takng apart you car, starting with the 2 speed, next clutch. Focus on the drive train. Also examine your engine. Maybe your pull start too, if you have one. Somthing has bent, broken or shifted from your crash. You just need to search until you find it.

Sounds like a bad main bearing in your motor, worn crankshaft or piece of metal inside your motor. Feel the flywheel inside your motor, it should turn over smoothly, pull out the glowplug and look for something metal inside, then take the engine out of the chassis, and pull out the backplate and if I'm right you'll see tiny bearing balls, or worn out bushing material loose in the case. My guess is your bearing or connecting rod failed when you hit something and the balls came loose.

This sound is very familar with people who racing and they see their car flame out. They can restart it, get back onto the backstretch and flameout again. Your motor is most likely needs a new conrod or mainbearing. Do not run it again till you veryify this by dissassembling it or else you may completely damage the motor.

If all else fells... Try this site for help for your N4Tec... Also, are you aware that Traxxas backs there motors for 3 yrs... They do... Go to the link and I'm sure someone there or the Mod there can point you in the right direction if need be...

i would not tell Traxxas that you disassembled the motor if you try to get a replacement-that may void warranty. sometimes thats all a manufacturer needs to reject warranty. ..."whats that you say? you took the engine apart? well i am terribly sorry, but we will not be able to honor your request. have a nice day and thank you for calling Traxxas" i have never dealt with Traxxas on that level, but you have to carefull about things like that.
