I found that by spacing the frame up about 1/16" the pony trucks would swing freely and not have the derailing issues others have had. I put an extra nut on the screws that hold the motor mounts to the frame. The nut goes on the screw between the motor mount and the frame and effectively moves the frame up for more space.
