Well I'm currently working on this:
and will make the wings by this method:
But I've blown the model up to 100" wingspan and will build two fuselage pods that the wings will bolt to, one with an electric motor and 7 Cell pack and the other as pure glider. I'll also be adding a small a parachute to the aft end of the pod which will be deployed on short final.
A friend of mine had a German kit called the SB13, about 80" span that had the chute and it was cool to see it deploy on final approach.
PS The wing twist has been reduced to 4 degrees.
