“5 gallons of fuel will not help.  To be effective in balancing CG, Moment is computed as Weight x moment Arm.  With fuel, the moment Arm is near the CG and thus the weight of the fuel is not helpful from a CG standpoint.  In fact, my understanding is that the fuel is generally designed to be near the CG so that the CG doesn’t change (much) as fuel is burned.”

 

Rick,

 

Forgive me for interjecting here, and maybe I misread what you meant but I don’t think Brent meant 5 gals of fuel for CG assistance, I think he just would rather be able to have an additional 5 gallons of fuel somewhere instead of batteries, gizmos or whatever. Watching our ounces means we can put more gas in our planes, which means the engine keeps running longer and can therefore keep us cooler on a hot day…
