OK , so quite a few questions have been done on 2/rev shake and the stiffness of the mast and using a slider head.
If you were to do a tractor gyro, and wanted to use a round mast to prevent using a slider head, with the lower section of the mast (about equal to height of the seat) used for the main engine mount (about the same height of the engine mount on a pusher gyro) with the same approximate bracing between the mast and bottom frame and the engine mount uses a tube clamp to the mast. Also only using gang nut plates inside the mast for attachment to bottom airframe tubing. No triangulation above this area and approx 40 in of the mast is unsupported.
Would the following be acceptable mast material choices:
2020T3 2"x .065"
6061T6 2.25"x .065"
6061T6 2.5"x.065"
4130N 2"x.065"
