RE: any takers on the Prop SR71 Jet on RCU ?
I've tried to fly the Flyboys SR71 with to crashes on takeoff. This plane has a OS 46 fx and seems to have plenty of power. It takes full up 50 degree elevator and a very fast takeoff speed to get off the ground. As soon as the elevator is lowered toward neutral the nose drops and plane plunges to the ground. It appears tobe nose heavy and I've moved the CG back about 0.5 cm but still hard to get the nose to stay up. Will try again with another move of about 1 cm CG move aft. This will put the CG at 21.5 cm or behind the main gear and will want to drop the tail if the nose is tiped up. Flyboys didn't respond to my questions about CG and flight performance.
