Restoring a Soarmaster

[jedi]

Soarmaster,

Thanks for post #5. Looks like you know what you are doing. Specifically what wing is that? What company were you with (Texas)?

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.
