hi,
It looks like it is working, but way too forgiving. Dogfighting for 20-30 minutes over the channel and Kent is not a problem in an E3 with full throttle and rpm set to around 2400 with constant WEP usage. I normally take three quarter of fuel and thats always enough, never had to RTB because of fuel shortage but then its not that easy to live long enough to see my fuel tank empty
