Hello... I have a brand new traxxas revo 3.3, just started using it yesterday. Now it won't engage in reverse. If I give it a little push it will engage in reverse but makes a clicking sound. Once I hit the brakes then try to reverse again, it will not engage. I can't find any solution to this problem in the manual the truck came with. Any ideas?

there should be a nut with a spring, try to tighten it a little

Your clutch is wet. You need to drill a very small hole less than one eighth of an inch at the bottom of the EZ start. A thumbs up would be greatly appreciated if answer is helpful for your question. THANK you and GOD BLESS

Hi
2 stroke engines are very simple. If there's fuel (under pressure) and a spark it will run. Check the glow plug by trying to start it with glow plug removed but still connected and touching the engine body. If the little center wire glows bright red, then it's OK. Only do this for a second or so. If the plug is OK then it has to be a fuel problem. Traxxas has a long history of cracked gas tanks. Good luck

check your remote, the three switches on the bottom.. they control the servo's. one controls the forward and backward servo. test em out. one is bound to turn the servo around.

Sounds like a problem with the opti drive module. It may need adjusted.

try setting your idle down a little more. if your idle is too high, it wont shift into reverse. also check your linkage. make sure it pulls all the way out and pushes all the way in when it is off. try starting it with it already in reverse and see if it works, if it does, then it is more than likely your idle.

Remove the glow plug wire and there are just a few bolts that hold the head on. Just make sure you install the new head with the head shims like they were under the original head.

you might need to reset the opti drive. turn the power on with the engine still off and hold down the optidrive button for 5 sec. see it that works.
