Iron eagle,

I dont think I would want to replace the electrical draw of the 10s setup, but if the solar cells could replenish say, 10-15% of the draw- I think it could be beneficial. With that number in mind, it might be possible to make the upward ascent in "stages"- stopping at various altitudes and gliding for a couple minutes to allow my 10S setup to recharge. Using 5-6 solar cells would only weigh about 36 grams, and the distance between the solar cells and battery packs minimized to reduce wiring weight. As far as reducing the wing loaading... Im really not willing to make my wingspan any greater than 14ft... plus anymore wingspan I add to the wings will require more and more reinforcement to an already likely weak structural area. I do think the wing loading will be adequate. The fuselage itself will have body lines and a nice planform which will generate SOME lift...
