When I first set it up I did not like the plane at all the CG was set at 5 in and built by the book but it flew terrible. To make a long story short I ended moving the motor 1/2 inch forward on the mount and it flew like a different plane. There are 3 other Twists at my field and now all of them have moved there motors forward. You would not believe the difference it made in the way the plane handles.
