I test flew mine today with the CG at about the same-- here is what I found. With 3D rates it reminded me of my Pizzaz. Very nice flying and very stable at lower rates and slower speeds: however I do have a concern about the CG or upthrust--or downthrust in this case. When I pulled a 45 upline and rolled inverted the plane climbed stright up in the inverted position--when I rolled upright it would dive a bit until I got back some speed. Stright and level flight was dead on perfect until I rolled inverted and then again it would start an outside loop at a good steep angle. Any ideas??????
