[sm=spinnyeyes.gif]well of course there IS a reason so many la 15s are having problems in crashes. it is because there simply are so many la 15s on the front of combat SSC planes. they are the most often used engine because of their reliability and low price. any engine on the front of a combat plane is in for a rough life .... "its combat baby" .... so we try to design to help the situation knowing there can never be a cure. the la bushing set up makes for a lousy pusher so that's out, and complicated mid engine designs are just that "complicated". (come up with a simple mid engine tractor design that flies well and become famous!!) several of the guys that kit and fly really good SSC fighters have implemented breakaway motor mounting, its not new. but we strive to make things like this better if we can and bouncing new ideas off the rascals on this forum almost always helps beside its so much fun to RAZ you characters!
