RE: ParkZone J-3 Cub RTF

I know how frustated it is when you have to cope with equipment problems while learning how to fly. I've tried replacing bent shafts before and my success rate is around 50%. Those shafts sometimes appear to be welded to the armature and you just can't hammer them out.
I learned to fly with the Parkzone J-3 cub about three years ago and thought it was and still is a great little plane. We flew the J-3 with brushed motors then and they lasted about 25 flights before they started losing power. However, they were only $9.95 each which was not bad.
