But you're worrying me about the choice of section now, I'm not good at reading the sections tables but if I understand properly these sections I proposed are only 1 degree difference stall angle. Main wing S3016 and Canard S3021 add the one degrees decalage, so you think a 2 degrees stalled angle different is enough margin of error to make sure that the canard stalled first.
Tony, this is open for discussion but if it were my model with tractor power, I would draw the plans with both airfoil's reference lines at minus 1.5 degrees. This would give alpha zero on the main wing and alpha plus one up front. The two degree stall difference at zero power seems like enough to me and the down thrust with added power would be in your favor as I see it.
