I was curious, Yak-3, spit16 and P47M.
The test started at 50ft on WEP if possible at the fastest speed. Flat turn left, record speed just before turn right, flat turn right record speed at end, barrel role, record speed at end into a vertical popup. Hang on prop and record alt and speed plane stalls off to aside.
100% fuel, full ammo load, WEP where possible 50ft level alt.
Yak-3
Max speed - 350
Left turn end speed - 332
Right turn end speed - 328
Barrel role end speed - 276
Popup stall alt - 2700ft
Stall speed - 90
Spit16 WEP
Max speed - 340
Left turn end speed - 320
Right turn end speed - 290
Barrel role end speed - 206
Popup stall alt - 2600ft
Stall speed - 90
P47M WEP
Max speed - 362
Left turn end speed - 332
Right turn end speed - 285
Barrel role end speed - 205
Popup stall alt - 2700
Stall speed - 85
Lazy comes to mind covering so many human aspects of this farce. I experience Fugi's whine all the time chasing spit16 and P47M and chances are by the time I run into them, they are a lot lighter from burning off fuel and ammo. I don't need to test the Yak-3 on half fuel, it's obvious what the outcome will be. Our Yak-3 is the monster the Russians say it was while our spit16 and P47M are the monsters the RAF and AAF said they were. Bunch of laziness going around.........
