Default RE: Hellcat Build with 250cc Radial

The full size Hellcat had an extremely complex flap mechanism. As it went down it also moved toward the rear. My plan is to make it look reasonably scale without the complex movement. After all this has to fly. Attached is a bottom view from the 3views showing the locations of the flap hinge. There are two flaps on each wing. The flap that is outboard of the strut has three hinge points. The other flap that is inboard of the strut only has two. This inboard one is no problem. I will put two hinges with a single servo. Since I have a wing break on the outboard flap that is in-between two of the hinges that will leave the flap on the removable wing tip with two hinges, which should be fine. The problem I see is that there is a short section of the outboard flap with only one hinge. This is where I am going to add a hidden hinge. It will work just like the others but the slot in the flap will not be visible from the top or bottom. See the drawing and machined flap hinges below.
