I'll throw in my 2 cents. Dual ailerons, fuse mounted gear, about 1/2 recommended dihedral. Flying here in 'mile high' land, I've had success with OS .91FS turning 13x8 but even more fun with the Saito 1.00 and 14x8. Plane is also an EXCELLENT float flyer.

I'm considering building another (someday) with retracts. Anyone tried that yet?
