More details on "In certain flight situations the disk can use the propshaft as a lever arm and 'walk' the nose around in yaw, which initiates a cascade of very negative events." Is this a dynamic yaw roll coupling issue?
Would the long shaft and a rear aerodynamic surface(s) add the required damping to a modern glider design with an extended keel?
I am thinking an inverted V tail with 1" OD x 0.053 wall leading edge for damping and prop protection.
