Is this of value?
13.4 Aircraft Endurance

I looked into this (not the above link; Internet hadn't been invented) many years ago when I was considering an affordable means of keeping flying; such as build your own aeroplane. I’d been recently inspired by the, then, new BD5. There was a much simpler formula that related the coefficient of lift/coefficient of drag ratios at different speeds for a particular wing section but I’m damned if I know which box (of many) I placed the papers in. Cl squared over Cd cubed Max rings a bell. I never got as far as worrying about power and fuel burn curves.
