Also ,any binding will also put a strain on the other stuff ,causing over heating of the electrics ,
like the motor or speed control!
Good luck ,an glad your here!...:cool:
I also been looking to get a tank!....:thumbs-up:
It sounds like the gear is binding ,Take the gearbox apart an shim the gears an grease them!
Most hardcore RCer's will do this to all their drive train ,an not trust the manufacture's ,
a lot of times the housings have faults in them in which some material has to be removed
from the housings...
