I found this in the NACA flight testing of a P-80A airplane. Very interesting, it goes in depth of the elevator and other control characteristics.

NACA experts considered to elevator control forces excessive. The control forces were 10.8 lbs / G at low altitdues, but at high altitudes it could be double, tripple, and even 4 times as much, ie. 45 pounds at 0.822 Mach. Because Mach numbers are lower at high altitudes, this means that excessive elevator forces can be expected even in normal level flight.

For comparison, elevator control forces for the Fw190A was 9-12 lbs / G (and was considred a bit heavy), and 20 lbs / G for the Me 109E in high speed dives (which was considered very heavy).

It`s seems P-80 pilots should better start to do some workout until there`s time. /i/smilies/16x16_smiley-wink.gif

You didn't find it, Isegrim, I referred you to it.

WOW!!!! A whole 45 pounds.

I think you're on to something here Isegrim.

Yet the P-80A still outperfomed the Me-262 in every regard.

10.8 lbs/G doesn't seem that bad. Pulling back 50 lbs with both arms isn't difficult at all.

Do the same numbers exist for pushing forward?

Also, was this the justification behind giving the 190 such godawful high speed elevator input in the game?

There won't be a lot of manuevering at mach .75 at 35,000 feet, much less at .822.

Given this game's altitude restrictions, the P-80A will do extremely well.
