But the motors I use are different. To begin with I had four motors, two where place near centerfield. It did not perform. it works much better with two motors. I will move the motor at the end that is slower and adjust my screws that support the board at the 25. I will see the result.

This is fun adjusting a board. One end is perfect the other end needs to be improve. By the way, I use double side adhesive foam tape. The motors are well attach to the board and are easy to move if I move them around to adjust them.
