Dualsky's  EG Capsulated series of electric glider motors offer the great torque and cooling efficiency of out-runner brushless motor technology, but the spinning outer bell is enclosed in an aluminium housing. This prevents anything in your glider's fuselage from being abraded by it, which could end up destroying a perfectly good airplane.
