LesUyeda;
I agree with you on moving the CG back, but IMO you want to move it too far back. Making a flat-bottom trainer fly nearly-hands-off inverted would probably call for a lot of down elevator when flying straight and level upright. I would move the CG back a bit, but not too much.


One of the problems you meet when trying to make this type of plane fly inverted, is that it (because of the wing profile) will need a huge angle of attack to fly level (inverted). It's a good thing you have plenty of power, because this AOA will create lots of drag. Most likely the airplane will be easier to fly inverted at high speed, and terrible at low speed. My $.02. Good luck.
