Help just got my buggy together and now my brand new ofna 10247 starter box and it starts fine but the drive belt comes off constantly any ideas please help.

I have the same starter box and had no problems at all .

Did you assemble the box yourself or did you buy it RTR?

Mine was RTR, but I had to move the starter wheel around for 8th scale. In the process, I forgot to put a screw in the starter wheel. So, it moved off and the belt went with it. I had to look carefully to see that the wheel had come off.

it's the RTR box but I did take it apart and put it back togrther. The belt come off of the pinion of the drive motor I tried different tensions with no cure, this is making me CRAZY.
