That's the typical Debonair airfoil I was talking about. The sharp leading edge is going to be your problem as it will stall very suddenly instead of gently like a Clark Y airfoil or the typical blunt leading edge airfoils used on trainers. There's a good reason why the spad guys go on and on about how much their planes can take a beating; it's because they crash so much usually due to bad aerodynamics and being overweight. It's actually quite difficult to get a proper leading edge with coroplast, but the planes can be a lot of fun anyway. Best of luck to you on the first flights.
