Photo showing Arc rear clearance. More than I thought. But a hinged keel tube for the wish list maybe down the road.

Â I think the tube would be fairly straight-forward to make, and basically the APEtzxerz (man I hate typing that freaking long name and having to look it up all the time so I can spell it!), hereafter known as the Arc, pretty much has the tail tube tied into the D-tube leading edge and the fairing around the pilot. Â I'm thinking that shouldn't be too difficult to do. Â And the nice thing about it is you can build the wing, and the sling/seat, and test fly it before you put on the fairing.
