Actually, that was a fantastic breakdown on the subject and the web site reference took it another step forward. I appreciate you taking the time to explain that for me...always nice to learn something new. Again....thanks very much.
Unfortunately....Aerobird III (rebuilt w/ GWS flight controls inside) died a sudden and painful death last night. I was up 100 feet or so, bringing it around in a gentle circle, setting up to let a friend drive it via my Buddy Box. Something failed and I tried to recover the fall one to many times under power, which drove the plane into the ground at 30+ MPH. It's toast. In all my Aerobird crashes of old, when I was learning to fly, I have never completly wiped out an Aerobird, in one crash, like I did last night.....and in front of 2 good friends!!
Aerobird IV - (using parts from # III), will fly again, but many hours will be needed to construct it. Maybe like all experimental aircraft, #IV will be even better.
Thanks again for the information.
