RE: U2 Spyplane
John,
My wing has zero washout, flies well. I put a couple of degrees of reflex in the ailerons. Flaps are plain flaps with the Robart large hinge points set at 45 degrees ___/\_______ so they have a fowler effect. I'm using one 8611 servo but it really could use two for extra stiffness. The each flap is nearly 3 feet span so if the flap isn't stiff you need more servos. Like I said, the airplane gets a little unstabile in pitch when I lower the flaps so I'm going to add nose weight and elevator flap mixing on the next flight. Gear is a Robart 630 in front and an old Spring Air unit in the rear.
Here's the link to the new firm in Germany that's selling the U-2C : [link]http://www.paf-shop.de/[/link] They offer fuel tanks and a pipe as well.
Sean,
Your pictures tell the story. Thanks!
