Good motor(Posted on March 27, 2013)
I've had this motor about 5 months now, and it has given me good service. It has survived 4 different foam planes, two deltas and a Blue Baby fan fold. It survived two "lawn dart" crashes on the Blue Baby, the last of which the plane itsself did not survive-the fuselage broke in two after the wings folded (my fault for not building the wings strong enough). The shaft still turns true-can't ask for more than that after what I have put it through.
