Bruce,
First of all, thank you for taking the time to reply to my concerns on the large scale U-2.

With the approach of the systems testing and radio programming for this complex airplane, I appreciate your input. Large differential aileron and rudder to aileron coupling will be incorporated. The idea of the smaller version powered glider was thought about some time ago. The closer I get to the first flight the more likely I am to to practice with something not so critical. I need to be sure I'm not in the bank and yank mode since I fly the short-wing turbines. I had an 80" ducted fan U-2 but it flew much too fast. It's demise was met while in a turn, unable to roll out.

For additional roll control and to counter aerodynamic dampening, the flaps will be mixed with the ailerons to a max or 5^ up. I prefer to mix only the outboard flap but this gets too complicated with the radio. There should be plenty of drag as the large speed brakes extend >45^.

I was told that the Reynolds Numbers that this model operates at, is much like the real one was at altitude. Not Sure.

Yes, I have done extensive reading on the U-2 and retain a copy of the Air Force -1 (flight manual) of the early one. There were many flying lessons written in the manuals in those days. Perhaps because of the many losses.

I have the onboard camera standing by as well as an anxious 1/6 scale test pilot!! First flight in '05
