RE: HENG LONG OWNERS ONLY THREAD!
Hmmmm, seems the board is well cooled. If the chain lube is anything like the stuff I use, it is very sticky and stringy....might be too much for that small motor to be able to turn. Pull out the motor like I suggested and try and turn the gear that the motor meshes to- it should turn very easily. If not, track down where the resistance. I used Lubriplate for my gears- it is an assembly grease, very thin and runny. I wanted to be sure that there was as little drag as possible on the motors.
Good luck. I''ll keep watching for your posts and maybe we'll be able to figure out what's going on. And remember- "Life without challenge is life not worth living".
