I've found the manual with your chart and to add more confusion, mine comes from a later revision. This is from your chart: Corsair Manual.pdf null This is from mine: F4U-1D Real Manual.pdf This sentence also could be the hint that higher MAP could technically be achieved, but shouldn't. That would also explain 61" during my tests and would mean that MAP simulation is at least good enough. My new guess as to why our charts differ is perhaps this is a safety issue. No two airframes are the same and after a while they decided to increase the safety margin.

Two more things came to my mind: 1. At WEP you're not really concerned about efficiency since you want as much power as possible. 2. The asterisk in @felixx75 's chart is for Mil power so the reason to use 2550 RPM for WEP must be different.

Since I'm getting 61" at 20k I'm not so sure about that.

I was asking because at 20k ft I was easily getting 61" at 2700 RPM. I find it strange especially since in the manual provided by M3 there's even lower MAP What's also interesting is the recommended 2550 RPM which corresponds with another Engine Flight Chart I found: Why 2550 RPM? Should the engine not be able to sustain 2700 RPM (which to me seems odd since it's a matter of pitch angle)? Or does 2550 provide more thrust (in which case I also don't quite understand how)?

Where did you find that number?

Perhaps this can be of use: Corsair f4u-1d-detail-specification.pdf

Here's my file structure: nullnull Here's what I did just now: Made a new mission in ME, placed a Mosquito as client (start from ground) and ran it: mod didn't work - the horn was present. Quit to desktop, restarted the game, run the same mission from the main menu: it worked.

Did a quick test myself. Sea level, 15 deg C, Standard atmosphere, fully fueled, all coolers, cowl flaps, canopy etc closed. MIL (2700 RPM, 54 MAP): max speed 297 kts, average was about 294kts vs 304kts from the chart above (converted from MPH) WEP (2700, 58.5 MAP - looked more like 60 to me but the needle was shaking): max speed 314kts, avg about 310kts vs 317kts from chart. In conclusion: a bit slower but not much.

Worked for me, but one time I had to restart the game for it to work.

Until it gets fixed you can turn it off completely with a quick workaround:

null From real F4U manual. Blower and Mixture are the columns you're interested in.

Thing is, I'm not sure the gyro should freeze when past 55 degrees. What's more strange is that from what I've found all US fighters we have in DCS use the same instrument: AN-5735 which is limited to +/- 55 deg bank/pitch but it behaves differently in all modules: P-51 - as stable as a modern instrument: doesn't drift, doesn't stop P-47 - slowly drifts above 55 degrees but can be rotated while uncaged. Despite that it has the best "feeling" of the three.

Based on what I've noticed previously, this could be connected to pitch movement caused by the gear. With +1 pitch trim and gear down the aircraft pitches up below about 160* kts. The effect disappears above that speed. *I'm writing this from memory, I might be wrong about the exact speed.

Ideally you want to touch down at stall speed and at stall speed you need full deflection. That's why I don't recommend saturation in pitch.

I've found two more problems: 1. Pressing directional gyro cage button also resets it. 2. You cannot fully rotate the gyro with buttons
