RE: Great Planes Combat Corsair and Mustang
I believe that the prop was an APC 8 x 7 for that run. But, the static thrust was lacking for the hand launch, as evident in the video. It launches much better with the APC 9 x 7 prop. Also, in the photo you will see that I have significantly reduced the size of the canope and belly intake scoop (not visible) in order to reduce drag.
