was he leaking fuel, water or oil?..fuel..they fly till they run out of it, water, seems to take a little while to overheat, oil usually drops them out of the sky fairly rapidly. What makes you think you haven't torn off an alieron, the flight models decays but i have fought on, lamed up and the damage graphics are not coded yet. The convergence is too long for my liking 300 yds for .303 is tough. I would like to see it drop to 150yds or become settable(they are working on this) Unless you are right at convergence, .303 can be like BBs.
