How about the electric Radical R/c edge 540, airframe is 10 oz with electronics!!

Just kidding, try this plane, kinda like a 1.20 size Sig Something extra. wieght is normally around 9 lbs with a 30 oz engine, so you should be in the 10 1/2 lb range if you can push it back and not need wieght for balance.

I hear it builds easy and flies great.

You also may want to call CH ign and ask about the "roadrunners" he flies with conversions, kinda like a H9 stick but builds cheaper.....maybe you could add more surface deflection for 3d.


good luck
