from the P51 manual page 48

"Set trim tabs. Rudder 5° Right, Elevator 2° to 3° Nose UP (with 25 gallons or less in fuselage tank).
Elevator 1° to 3° Nose DOWN (fuselage tank full). Aileron 0° for Take-Off"

Please confirm the 1° to 3° Nose Down setting. As far as I remember, this is contradictory with the Accu-sim P51 familiarization video.

Did some of you ever try this Nose down setting with the fuselage tank full ?

There are some differences in Mustang checklists. I would try both and use the setting you prefer.

some manuals sad ,that use +2 ,+4 trim down

BUT!

if you have fabric trim cover, you (earlier versions had that) must use the current opposit!

a bit confusing i know

metal<>fabric trim tabs cover mistery..


What does Dudley used?

by the way! the Moonbeam had fus. tank behind the 2nd seat?

The 2nd seat on these modernized mustangs is where the bulky radio gear used to be, as far as I know, so that would not affect placement of the fuselage tank.

_________________

Radios are not THAT bulky The tank starts just bellow the height of pilot shoulders - when you look back the fuel gauge is bolted directly to the fuselage tank top surface. So every double seat Mustang have the fuselage tank removed, otherwise, there would be no room

With the trim settings.

I find that if I don't set any trim other than elevator, that when flying that I have to put quite a lot of left aileron otherwise she rolls to the right all the time.
Is this right?

Thanks

Assuming you don't have any controller issues and are calibrated correctly in FSX, the main thing to remember about trim settings is that what you read in the manuals are "suggested" settings. Each aircraft even of the same type will be "trim specific" as to its exact configuration at any moment in time. You can visualize this by considering that if ANYTHING CHANGES in flight, and this includes fuel and expendables burn and especially airspeed, required trim will change as well and have to be reset.
When flying a fighter like a Mustang, you should be constantly having to attend to trim both aileron (as fuel is burned from one wing tank or the other) and elevator (as airspeed changes so does angle of attack and thus trim changes as well. ) Note also that in the lower speed range where angle of attack is higher, a Mustang will be especially trim sensitive due to power setting.
All in all, the bottom line is that the trim wheels in a Mustang are always in play as you fly the airplane.

All this having been said, it your problem is severe it's most likely a controller problem. I've checked the flight model pretty carefully and it's extremely good as compared to actual behavior.

When flying the T-34C Turbo Mentor in the Navy I remember always having to change the trim settings . It has a PT6A turbo prop engine derated to something like 400 SHP.

Every time you made a power change you were adjusting rudder/elevator trim. You were used to doing it so much you knew where to spin the knobs right to the desired setting without having to look or depend on feedback. It was a fun plane to fly, plenty of excess power but I'm sure nothing like a warbird so I'm sure every time you make a change in the P-51 there will be those two trim tabs to adjust. I would use the keyboard shortcuts to make it easier to change the trim setting.

(now when flying jets it was easy to fly. Dang rudder peddles are foot rests! We used rudder and aileron trim to compensate for a bent up airframe)

Wish there was a trim flight sim peripheral. I think Saitek was not on the ball with there trim wheel. They should have made it with extra dials for aileron and rudder trim! pitty

Thanks for your comments.
