RE: Low Wing 40 size plane?
If you're looking for a plane to practice in cross winds, I'd go for a trike. I am very very partial to WM so I would recommend a SS40S. They may not be the prettiest planes but they definitely are one of the sweetest flying.
By the way, if WM people are reading this, let me know so that I can tell you who I am so you can give me a bigger discount next I'm at the store, you guys are way too cheap with your discounts! :-) Honestly, though, WM kits are really great... easy to build and super to fly. Some people say that they don't last over two seasons... I have a solution to those problems, fly often!
