The Ranger is, essentially, the front half of the CE with a tail boom in the back. And the original CE was aluminum. I think this pod and boom layout would work great in aluminum."
I think you had me at this "hello!" Man is this a cute concept. Pod and boom, and in aluminum, which is a little friendlier to tying down outside for a flying season before folding the wings and taking it home for the winter. The cost of hangar is significant. I've got a PILE of aluminum sheet and angle and would dive head first into this...
They're just like every other set of cabane struts that aren't V's or N's. They have a set of crossed cables that keep them from racking....It seems to me that there's not much stiffness against a siide to side movement of the upper cabane attach at the wing root rib.
There are several things preventing the wing from twisting on the wing pylon. Twisting strain on the pylon would be reacted as tension on the cabane cables AND torque on the leading edge "D" sections. Even without the cabanes the pylon can't twist on it's axis unless the D sections twist on theirs....where is the resistance against that movement?
