Hey Dick, I've also got one and will use the BME 105 (will be the Extreme whenever they get here!) I'm REALLY interested in what you did to lighten the tail. Only thing is that mine must retain the removeable stab. I'm almost at the point of balancing mine, and from what I've heard, it will probably be tail heavy, even with rudder pull-pull.

Glad to hear it flies well (you're a trooper, getting out in 100 degree heat!).
