When i start my truck the motor starts to REV very high and wont go i can see the gear spin at the bottom but think maybe something is not catching up top. last time i drove it was fine it did REV up...

you have two different problems. The engine is reving high because fuel into the engine is being starved i.e. the fast idle is set too high. This can eventually lead to a ruined engine. Traxxas engines are designed to run very rich with a heavy amount of oil to keep them cool. Retune your engine. Secondly your clutch shoes have probably glazed over or are simply worn out. Replace these. There's alsways a possibility that you've broken a gear in the transmission but the clutch shoes are much easier to replace and probably should be at regular intervals. Your manual will explain how to change them and how to retune. Good luck

Revo spur gear keeps getting stripped

Youre not setting the right gap between spur gear and clutch bell. all the adjustment is on the engine side so once you got youre spur gear in place loosly fit the engine. Push the engine close to the spur gear so the teeth interlock. Cut a long thin piece of paper and feed it throgh the teeth.turn the clutch bell around. It should feel the same all the way through the turn. If not push the engine closer if it starts feeling loose or ease it away if it starts feeling tight. the paper should come out the other end with a step pattern. the reason for the paper and turning the clutch bell is even though the teeth are intwined at first, once you turn say 3 quaters of a turn if the engine and transmission is not parallel it can move 3 to 5mm in either direction. Lastly use thread lock on all bolts as the vibration can move these and hey presto you are getting another one. Hope this helps.

Sticking in and out of gear

Hi. When you say in and out of gear, does it free-wheel or just not drive? The jerking could be caused by faulty motor brushes. Fitting new brushes or getting the motor overhauled would probably fix this.
If you gave a better description of the fault, we might be able to give you a better solution. good luck. Neil.

Truck wont go

Have you checked the output and dog gears in the transmission? I broke the teeth off my forward gear and all it was doing was revving up really high but not going anywhere, it would still go in reverse though. has exploded views of the transmission so you can take it apart and look inside to see if there's any gears missing teeth, or if any of the bearings are seized.
