The wings will spring back some, but not all the way. With the washout, you can just glide in slowly without much worry about stalling. The sport wing is more desirable, for the trainer dihedral is overkill on this plane, flies nice and stable.
I had trouble with the control arm on the nose gear on mine. Plastic has some give, but doesn't take repeated abuse. A spare control arm may be a item to have on hand. I have a fult's dual strut on hand to put on mine, likely won't get to it for a while.
I had to add a lot of nose weight also, built heavy on the tail. Put a 5 once heavy hub on the engine, and 3 onces on the firewall. Engine runs smooth with the "flywheel".
Been thinking about putting it floats too. Just need time to do it...
