Your cg is not where it was intended and and actually is considerably forward thus a chief contributor to your problems among some of the other lesser problems listed by the fellows.
The old sage advice to always balance your airplane with just 'a smidge' nose down for 'mother and country' will result every time with the CG forward of your real target CG point. The problem is there is no way to accurately communicate how much is 'just a smidge' or even a practical way to measure degrees. Your five degrees down is way to much.
When actual weight and balance measure is done to full scale airplanes great care is always taken to level the aircraft and with our model aircraft its my belief that it too should always be done with the airplane level and never with any nose down.
