RIM with bearing (PlanePrint.com BIG Bobber)
I add a bearing to original Rim of plane Big Bobber (Planeprint.com).
The idea was found reading the solution of Planeprint used on the CUB model.
Bearing can be purchased at AMAZON :
Cuscinetto a sfera 684ZZ doppio schermo, 4 x 9 x 4 mm in acciaio al carbonio, 20pz.
