Let me describe something happened last monday night :
I was on a superb knive fight with a F4U in my Yak at 3/4K with a country mate in a "blue abomination"

at 10K+ (for me after 10K it's the stratosphere ,I'me a metric system dweeb unable to do the proper convertion

without errors )
I was working like a surgeon

removing part after part of the F4U (1st one aileron next the elevator etc ...) after seing the F4U spinning to the ground (at this state he is obviously killed) I extend to grab alt for another fight just to see the ù*^$^$^ù*ù country
"mate" diving on my prey spraying 20 mm shell on it and get the kill

.
I just want to know how the assist is determined by AH it the weight of bullet who is used or the critical effect of the impacts ?
I'm sure the F4U can send more weight per second than a Yak but it this case it's not fair
Disgusted I've logged of and I'me seriouly thinking about buying Q3 !
