Hi Guys,
I've been nervous about the W&B of my Onex for a long time now. I used a heavier engine, a heavier landing gear, a PC680 battery, long wing tips, Installed a baggage compartment, ... All but the wing tips and baggage compartment were forward weights on a plane that is already tilted toward forward CG to accommodate large pilots. Yesterday was the day of reckoning. Scales, plumb bobs, fuel supply, etc.
How bad is it?
Empty weight 638 lbs.
CG is 58.71" aft of the spinner tip which works out to 7.835" aft of the leading edge or 15.67 % wing cord.
Lightest possible pilot with full fuel and no baggage ~ 150 lbs.
Pretty porky and a bit forward on the CG but no worse than I expected. It is comforting to know that there is no aft CG danger with me (~ 190 lbs) at the controls.
Forever Forward,
Wes
