John,

I'm confused. the pressure in the tank remains the same no matter how big it is. Given that there is pressure and a bigger tank won't take the pressure away, fuel flow should be indepedant of the tank size. How would a larger tank reduce the fuel delivery capability?

FYI - We have a 12 oz in a 40 sized trainer, combined with a 2200mA battery, so the beginners can fly until they are tired and not have to turn the controls back to an instructor to come in to refill => more stick time. It works out perfectly.
