Cant you put some new bearings in the SK3 to keep the plane flying? The rear one is 10mm od x 5mm id x 4mm wide and the front ones (two off) are 8mm od x 5mm id x 2.5mm wide. I'd not condemn the motor as crap just because it needs a bearing, for 3D flying bearings are very much consumables and sometimes you just seem to get a bad bearing that doesn't last long. The tiny 8mm od bearings in particular are quite fragile.

These are a common size for motors with a 5mm shaft, in fact the Motrolfly DM2820 uses the same size, but it has two at the back and three at the front. Even so I've had to put new bearings in the Motrolfly twice.
