Looked at the AARMA site. The slipper assebly looks identical to the associated. I would try to find a spur to try and see if it fits. You need to go to a smaller spur as the large pinions will push the motor to far back and might not even fit with the large spur. plus it will change rear traction and cause over rotation.
