Near the end of the text it says the N had a speed of 397mph at 10k.
Looks at HTC's Jug charts in the planes section and you will see that the speed increase is more or less linear for the P47's from 10k up to 25k.
Although this may be an inaccurate way of comparing, it's the best till we either find real numbers of actually get to fly it.
Speed difference in the other Jugs betwene 0k and 10k is almost 30mph.
N speed at 10k = 397 mph. Withdraw 30mph from this and you get 367.
So say around 360-370, not enough to compete with any of the fastest planes, LA7 will eat it to lunch most likely due to the weight if the N modell, Dora's will still be easy cause they can't turn for S***. P51's will eat it for lunch as will a well flown G10.
Question is, will anyone need more then 50% + DT? In normal Jugs I usually go 100% and DT, same thing in almost every plane except P51 and Ta152 but don't see a reason for that with the N.
