gear mesh problem ? so the driveling without the motor seems smooth spinning tires or spur to check the pinion on the motor spins smooth but as soon as the pinion and spur mesh no matter how tight or loose the mesh is it feels like its skipping gears on the spur when i spin the wheels gearing is 24 81 rm3 ,, any ideas? ive already taken it all apart and everything looks fine and it was put together right , and i just drove it with no problems walked up stairs and then it started ,, by the way thanks for the forum thats why i bought this buggy i love it after only driving a slash 4x4 and last rc were in 03 back in the brushed motor days
