You haven't? Then where have you been? I've got several planes with great motor/speed controls bought as combo deals for $20 or less. Example you be a 30 amp Tower Pro ESC along with a BP21, 12T, 18T, or other such motors. Brushed is a dirty word these days. They wear out and do a gradual downslide in performance. They are in general less efficient and with less wide performance windows than a matching brushless motor. Same thing with lipos, at $29 for a 3 cell 20C 2200ma pack I won't even touch a nimh or nicad pack anymore, except for in my TX. Just as gas and balsa are experiencing a slow death in favor of electric and foam, brushed motors and nimh/nicad are going the way of the dinosaur.
