Here is a sketch for a twin electric forward swept flying wing stunter.  I have had great results from this basic concept in both CLPA and slope soaring and even free-flight.  See the 1/2A forum for my latest "wet" model.

However, there are some real advantages to going a twin once you are flying E-power, so why not combine all that into one big disaster... umm... concept?

I see this as either twin .061 or .09 equivalent power, full fuselage, geodetic wing D-tube for rigidity.  (Where is Bob Hunt when you need him?)   Area about 300 sq.in., should fly on 55' of .012 line.  I expect that it will do the full pattern in totally competitive style (flown by someone with that cabapility, not me, being "Designman" not "Pilotman")

 Now THAT would be different!

Maybe a biplane version just for some variety?   

I like it, Larry!
