I agree with most of that Alan, except the wash-out. If Sky wants to fly the model as a fun-fly, he'll need the same handling qualities both upright and inverted. Wash-out will become wash-in when upside down and will lead to unexpected wing drop. As it's a low-aspect ratio wing, if built flat there shouldn't be a significant tip stall problem, so there's no real need for wash-out on this type of model.

Therefore, I suggest you build the wings and tail flat Sky.

A fair comment, but ours were never inverted, except in looping manouveres, and our wings were parralel, so go Andys way, but i think it will flick in tight manoveres

i have 2 sides
no you dont,
yes i do,
