I modeled that in Motocalc, either the EDF 50 will work (poorly, low
thrust to weight ratio) or mounting a GWS IPS-DX2BB in the nose
(the "2" Gear, spinning a 7x6 prop), for which you'll want at least a
250 mAh battery. A folding prop would be nice.
I never did this project because I came to the conclusion that I
wanted a light little sailplane and not a wierd looking little
parkflyer with no landing gear.
Not that there's anything wrong with that. It's going to be a cute
flyer and I hope you'll post pics. Here's the setup I modeled, using
2S E-Tec 250 LiPoly for power. That keeps your wing loading below 5
oz / ft 2 if you build light. Level flight is optimized between 14
mph and 22 mph, your highest static pitch speed is around 28 mph.
You can probably get a decent though not great glide ratio, but if
you get it up high enough you can climb, glide, give your cells a
rest then climb it out again.
Use your throttle 50% of the time, and you'll get close to an hour
out of the battery.
Keep us posted.
