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. --- In BugHLG@yahoogroups.com, "Mark" <holidaymarinegroup@y...> wrote: > > > Hi everyone, > > Let me introduce myself. My name is Mark and I live in New Bern, > NC.
