From an aerodynamic point of view unless the CofG is really forward (inefficient) the ailerons are too big and the rudder too small to recover from a spin. ;)

You want the spar to be at approx 1/3 chord over the whole span, too. (Thickest point!) Where you have it now, at the wingtip, it is much too near the l/e to be of any structural value.
Rule of thumb with areas - high aspect wing, high aspect fin. :P
if you are calm and collected when all about you are going berserk - you've missed something important!

Eric
high aspect wing, high aspect fin.
Not sure about.
If anything it is the other way round.

Wing aspect ratio 41:1. Fin aspect ratio 1.5:1. :P

Wing - fin aspect ratios.
Disagree all you like, Gents, but compare the fin of a glider with the one on a Cherokee, for example.
You have short fat ones if you like, I'll stay with the tall slim one! :evil:
