Inspired by the F8F Bearcat's insane time to climb to 10000ft from a standing start of somewhere around 90sec, I decided to see what the planes in game were cabable of.
Overall fastest:
Me163: 1:30
Top prop driven:
Spit16: 2:19 5100fpm max climb rate!!!
Bf109K: 2:24
Spit8: 2:25
Bf109G14: 2:25
Spit14: 2:27
Top Russian:
La-5FN: 2:37
La-7: 2:38
Top Japanese:
Ki-84: 2:43
Top American:
F4U-4: 2:46
P-38J/L: 2:48
Top Italian:
C205: 2:49
Tests begain with standing start on runway at a sea level field in the TA. All planes other than Me163 were loaded with typical ammo and 25% fuel. Started watch when firewalled engine and engaged wep. Used autoclimb once near climbing speed except with Me163 which was climbed at 0.54 Mach. Wep ran out on Ki-84 and was reengaged after letting cool down for 15-20sec.
I only ran 1 run with each plane, so order of planes within a few seconds of each other might be off.
