If the weather is good coming Sunday (temp 41 deg.F [:'(] we're only looking at the wind here....)
we can tell you how the protoype will fly with a Magnum FS 52 FSR.
Balanced and ready for flight she weighs in at 6.8 Lbs
Here she is tied down at a Fly inn 'cause there was a 27 knots of wind blowing.;
Wish us luck,
Frank (and Chris!)
