RE: Low Wing 40 size plane?
The Tiger 2 is an excellent everyday plane. If set up with the right CG and throws, it can be very responsive also, but still land better than any trainer. It also handles wind VERY well.
I also 2nd (or 3rd?) the votes for the WM SS 40 and T-34. These are GREAT flying planes...I own both, but do prefer the T-34. When people see me fly it, they are amazed at what it can do after seeing the smallish control surfaces on it. I flew the SS 40 all winter as my "ski-plane". It has about 200 flights on it and still looks great. Both of these planes have symmetrical airfoils, but are as stable as any plane with a semi-symmetrical airfoil, so I wouldn't worry about that.
