RE: Are My Calculations Right???
I am a model builder and have quite a bit of experiance with Models and Real Aircraft.And have to make that dicision alot when altering the design of crashed aircraft.It's usually found by suspending the aircraft by the wingtips and usualy slightly forward of the center othe wing width.The fuselage should balance and stay level if your close enough to fly.add weight if needed either inthe tail or nose.Loking at your wing I would say suspending it from the forward wingtips or very near will get you close? Good luck Alittle nose heavy can be corrected by changing the angle of attack raising the nose and adding power if you have any.But tail Heavy is almost doomed from the start never being able to get the nose down or even level to recover from a stall situation!
