I know the 262 is very fast but it doesnt have enough fuel in my opion...
Does not have enough fuel??

Do you have any idea how much fuel a jet engine burns?
1 more thing, at what alt do you fly your 262? My hard deck is 10K, my average 262 alt is between 15 and 20K. You do know that jet engine become much more fuel efficient at high altitudes. Try taking off on a 262, go full throttle look at your E6B, for example it says you have 20min of fuel left, climb to 10K it will say you have 40min of fuel left. I mean literally, jet engine have a
huge differents in amount of fuel burned at different altitude.
