Raked forward, great suggestion, I had not thought of that and will consider it.
A recap on the concept for any newcomers who have not read this thread from the first post.
Many pilots learned to fly, often self taught, in the early days of this sport on a "standard Rogallo". It was easy to ground handle, easy to fly and land standing up, often with no steps and light weight carrying back up the training hill. However, a little tricky to launch with a more critical angle than modern single surface flex wing gliders ( a little too high and you didn't get off and a little too low and you got pounded into the hill). The glide angle was poor, so steep training hills were required which made launch goofs more damaging to pilot and glider. Then in flying high there was the full luff dive chance and steep banked turns were not very good.
My "brainstorm" occured when I thought: how about a design which has all the good points of the Rogollo but with better launch characteristics and safe flight characteristics. A glider that was easy to ground handle (short span), light weight (hopefully under 40 lbs), a better glide than Rogallo (shallower hills, more small hill air time), slow launch, flight & landing (large area, high lift airfoil), good roll response, good pitch damping (not"twitchy" on pitch control), soft stall, etc. Basically a glider so easy to launch, fly, and land that the beginner gets that great first flight feel
that builds enthusiasm to keep coming back and strive for that day when he or she moves on to a general utility glider and the higher launches - the fledgling has left.
There is also the potential that this could be a fun glider for "dune grooming", working narrow, close in lift, on coastal dunes and small inland ridges. Definitely it's a special purpose, uncertified, glider just for training but it could have several other "niches" it fulfills in the right hands.
