I should get 261mph with the Rotol which is 290mph TAS. Essentially the Hurricane is 50-60mph too slow. When I looked at the graphs B6 provided too the 109 is faster than RL up to 6km too, so we have an inaccuracy of around 80mph!!

Your link don't work.

The RL tests measure the 109's 1.32 ata power. It's the "no WEP" line. This graph is slower 35 km/h (on the deck) than it should.


- pilot's manual
- game with WEP
- game no WEP

I can't follow you calculations, how do you get 80 mph difference...?
