jimweda, snowbird6 reports that there are GWS motors that are a match for the Axe CP tail motor and that they fly without any problems. I'm not sure exactly which motor it is, but this seems like it could be it: [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXHHF7&P=7]GWS CN12-RXC Motor Set Tail Drive[/link]. It's only $8.49 at TowerHobbies. You may want to contact snowbird6 to make sure.
