Bobby, The Skyraider is looking great. I have a dive brake on my AD-5 that I am, with Masor's help, working to complete now. Hope to post some pics soon. The brake is hinged at the front and the servo is mounted on it's side so the arm pushes the brake open to about 45 degrees.
The green in the first photo is the brake and the cutout can be seen in the second.
Keep us posted on the progress.
Say, Gains, how are you and Howard coming on the A-1 and AD-5?
