This plane is a remake of the WM Ultimate 30. Except for cosmetic, landing gear, cabane strut and larger frontal area, it's the same plane. Weight, span, area all the same.
I have an WM Ultimate 30 which I love. It will scat and do about every manouver in the book. INCREDIBLE knife edges. I use a Magnum 40 swinging an APC 10 x 6 which gives me almost unlimited vertical. An OS 46 would probably be incredible on the new plane.
A word about landings, when that engine quits, don't try and make the runway. Find a decent spot, nose down for speed and get her down. She don't take to gliding too well.
