P-40-E elevator trim...

[Guest deleted@50488]

Well,

 

I know this particular model has received at least one update to it's flight dynamics, but somehow I still find that under most circumstances I need like FULL tail heavy elevator trim for landing.

 

Watching from an external view I can see the elevator deflected up, hugely!  I'm not able to see such "phenomenon" on the youtubes of P-40s I watched ?

I am not up to speed on the P-40 but I do see in the second video that you posted that all three planes landed wheeled on rather than three pointed, which would affect how you want to trim. Perhaps you are more likely to land wheels on using a long concrete runway.  I use full tail heavy trim to three point most planes.

Thx unreasonable,

 

your remark makes all sense and actually agrees with what the pilot says during teh approach in this other video - well known to P-40 fans ?

Interesting: the old training movie recommends wheeling on for your first flights, but says that it can be three pointed easily.  Landing is at about 25 minutes.

Indeed,

 

and in other videos where the aircraft practically performs a 3-point, there's no way such a huge elevator deflection visible... as we have to use in BoK's P-40 E.

Now look what you have done!   You have gone and got me interested - I will have to spend tomorrow getting the hang of the P-40 and looking at it's elevator.

?

 

to add to the thrill, just check out this video...

 

It's not a 3-point, but certainly neither a wheeler... and you can't see the need for 100% elevator trim like in IL-2's P-40 E.... At least the elevator doesn't look like so...

 

(skip to around 1:12 )

In IL-2 BoK we have the elevator fully deflected up, even on short finals, within a wide range of loads... as easily observable on Requiem's tutorial:

I see at least two aircraft with the visual position of BoX elevator position being incorrect. I have heard something about the Mig and others but I am unfamiliar with those aircraft. The Spitfire has it's elevator in an incorrect position for level flight. I've asked and have never gotten an answer on this question.

 

Is the flight model tied to the visual position of control surfaces?

I guess it is, and I have also raised the Spitfire typical "elevator down" position in level cruise flight. We never observe that in IL-2 for some reason. I believe future patches might correct it.
