RE: Twin head Autogyro help
His rotors are spinning forward in the center and back at the tips of the wings. I think either way works well, but I prefer to have them spinning inward towards the center, because the prop wash gets the blades spinning faster. The best thing to do is try one way and see if it works.
The problem with this design is it doesn't have a flapping head and everyone that works with autogyros know that the flapping head fixed a lot of problems in the autogyro world.
