I don’t think you need to reinforce the wing on mini scout, the mini series is designed for indoors and for outdoors in calm weather, the folded airfoils provide necessary strength already, However, the mini F22 is a different animal, if you add the Kfm airfoil to the wing, it can easily handle 10mph+ wind.
I won’t worry about thrust angle on 7” and under props. Thrust angle is more important to a tractor than to a pusher. Even with 9“ prop on a tractor (on the extreme side your thrust line is way off the lift center like a high wing trainer) you still can easily correct the issue with a couple of washers under the motor screws. 10“ prop and up you would need to have thrust angle build-in on you motor mount.
