This is a design of Matsumoto, Pilot's famous designer

Originally meant for 3 Channel control (Throttle, Rudder, Elevator) and Balsa with a 10-15 Nitro Engine, with 1.3-1.4 Kg weight, it has been adapted in Corro, with a 2836-1500 KV Brushless Motor, and a 9*6 e-Prop; I have added Ailerons as a 4th Channel (reducing the dihedral)

The wing is 44" span and 8" chord

True Flat-bottomed wings in Corro are not easy to get, and not always desirable too from the build viewpoint. I normally keep TE-Spar flat, and let Spar-LE form its natural curvature

And now, this raises an interesting question on wing incidence and AoA

The designer (the great Matsumoto) intended the wing to lie flat, and the wing bottom to be parallel to the Horizontal Stab.

But now the wing centre line is not parallel, although 2/3rds of the wing ie from Spar -> TE is!

So my question, dear reader, is do I try to keep the wing C/L parallel or leave the flat part parallel? Waiting to hear the views of experts and non-experts alike 

Tried a new Wing Tip construction





Flat on top, tapered on the bottom

Weight without LiPo and vinyl trim, aileron pushrods & servos etc.

The AUW is 1020 grams
