Spit/109 sea level speed comparisons in 1.08 beta patch

This paper clearly states that these measurements had been successfully done on the Me109. and it is clear that they had been measured on the Spitfire, Me109, Buffalo and Whirlwind.

Only one flight was made, as operating a suspended static head from a single-seater aircraft with a rather cramped cockpit is difficult.[b]

So you agree that they were measured

Stalling speeds with engine throttled right back were measured/b] with flaps and undercarriage up and down, and the speed at which the slots opened were also noted ; in every case both slots opened almost simultaneously.

And you agree that they were measured in landing configuration (flaps and gear down), plus gliding config (with flaps and gear up).

It should be noted that this section in the paper is titled
Stalling Tests 4.4 4.41 determination of CL max
Would you really expect them to comment on the CL max at full throttle during stalling tests?

However, you are corect when you say that the CL max at full throttle was based on the SPit figures but the RAE did have the accurate figs on the Stall and Gliding configs which is half the battle so would be a good estimate

Nope. What RAE did can be best described as a reasonably close estimate based on guessworked Clmax, with wrong weight, and with wrong power.

Let me reword this for you
What RAE did can be best described as a close estimate of CL max at full throttle based on known Clmax for Gliding config.

so who's quoting out of context now, David?

I would say both of us missed something. However Crumpp when commenting on the RAE reply on the NACA tests missed a heck of a lot.

One obvious point which no one including me has mentioned, is that the RAE did have the 109. If their calculations said that one was better than the other at something, they had the aircraft to test the results. A luxury that we would love to have

PS - By the way, I have no problem you using my real name but can I ask what yours is?
