elevator trim

seems to be inefficient. even with fully nose down trim the plane wants to climb and you have to constantly fight that with the stick.(bug or was the elevator trim really that useless?)

Check for contol double assignments.

When I spawned the first time in a flying 109, it went straight up into the sky and even full stick fwd would not really help (+ stalling & lots of swearing, lol)

Turned out the cause was the usual DCS problem.

no its no mapping issue...i can see the trimwheel moving just fine...its just with fully nose down trim the plane still wants to slightly pull the nose up.

Post a track please ... my K-4 flies just fine with the trim at about "80%" (according to the controls indicator).

Full forward trim set before takeoff and left there for me. Still needs more forward trim!

I use a Saitek trim wheel and it's not working very well for me either, you can here the wheel sounds but no movement but then it starts going and won't stop, trim on a button works but are very sensitive and needs more down trim. Or is that how it really is on the 109?

^^well for me the trim animation works properly.thats not the problem.its just that only with full forward trim the plane will somehow keep straight.but even then its very slightly pulling up..

Trim animation looks fine when using the buttons but not with trim wheel. Full forward trim just barely enough. Full back trim will make the plane do some really crazy stuff.

I am using the trim up and trim down functions (buttons) and seem to have no issues. Are you guys using the axis?

Yes "Saitek Cessna trim wheel" works fine with the p51

no just ordinary buttons.again, its just the efficiency or maybe the range which makes trimming pretty useless.just trim fully forward and it will more or less stay straight, still with a slight tendency to climb.

I can confirm it too, although at higher speeds it stabilizes at full forward trim, and the pitching up moment ceases...

Very annoying at takeoff, and now I understand Wags takeoff video...

haha yeah, you really have to half way push the stick to not get into a instant stall on take off...also when spawning mid air the first thing you have to do is to trim fully forward

Same here, double-checked trim settings with control indicator (RCTRL+ENTER --is that a new feature in 1.2.12 with WEP, rudder, and trim settings all in the same box?-) and it seems that indeed with full nose-heavy trim the plane still wants to go up. A concern in takeoff and landing.

+1

Full fwd trim (2 position) and with neutral stick it piches up violantly at TO.

Don't know if it was like that IRL

..........exactly what i experienced too, plane wants to float upward....when i trimmed nose down full it still did it, not as bad but still. seems like the trim needs a bit more range on the nose down end.

maybe the weight balance (CoG) is not set correctly.

This really should be reported, cause every newbie will definetely crash on takoffwithout knowing about trimming the plane to fully noseheavy!

It helps to use ONLY 12:00 on the prop pitch, and ATA 1.35, as per the Manuals

Come on, the plane wants to go straight up like a rocket without trimmed right!

That can not be modelled right!

Ok, maybe this was a little over the top, but you have to agree that if trimmed neutral its nowhere near neutral!

That is not what neutral trim means.

The neutral you talk about changes with speed, which is perfectly modelled in any AFM plane that has positive pitch stability.

You might find this interesting.

So is there any source where you can see that the bf109 has to be trimmed totally noseheavy to takeoff safely?
