If any have tried this its really tough as a Jp fighter Ki-43-II as you fly some quite long missions then get to face P-38 and P-47 which totally outspeed your plane.
Playing with takeoff and landing my best score is only
9- P40
3- P38
3- Beaufighter
2- P47
1- B25
18 kills in 24 missions (and i died at least 9 times and had to replay those again
)
If you play Ki-45 change MissionDistance=Medium to =Short in Dgen_mod.ini else you get some really long flights to edge of map! (this uses the planes data range and Ki-45 is much further than Ki-43/61's)
