109 elevator trim

[Crumpp]

I believe OM and his team have spent more time evaluating the timing of the trim wheel than we did/do here and the 5 to 6 seconds we have now didn't come out of thin air.

That seems about right.

You do seem to dismiss things unless it is absolutely proven to you

No, if it does not make sense, it does not make sense.

It is like having a fuel reserve of 2:1.....It does not make sense.

When there are mechanical questions to be answered, I always reach for my Haynes

anybody have one?

He starts turning back (nose up), at 3:23, hits the stop at 3:28. That's 5 seconds.

Don't know how many turns or what starting position that was from though. But judging from the paint chips on certain parts of the wheel only appearing once, I'd say that was not even a full revolution.

I was being ironic, robtek With all due respect, the devs have modelled too many things plain wrong on too many levels, for me to have any confidence in their research and attention to detail. (The good thing is they might as well fix these issues one day and they seem to listen).

That 'thing' is actually a video from A2A dev. team

Yes, hence the design and purpose of the trim and flap wheel

Anyway Crumpp, next time you fly your 109, would you be so kind and report back to us how it really works?

Yes exactly, we don't know by how many degrees he actually trimmed the a/c. There is a cut and change of camera position to take a shot of that area. It seems like he's been turning the wheel before the cut as the hand is already in the movement. Great find anyway, you can actually see the gears and the chain speed. This person grabbed the wheel 6 times doing sort of 1/5 turns so I guess you're right, it appears to be a one full turn +-. Only assuming that he started in neutral position (0) and with 5.75 full turns for full range of 11 degrees, it seems to give us a good picture about the operation.

It looks like the original assumption was correct and this is not correctly represented in the sim at the moment. The problem is with other a/c, too (and their rather too swift and easy elevator trim response) but the plane benefiting from this fact the most (due to RL vs. sim discrepancies) is the 109.

S!

Let's not drag this down to a mud sling contest. Greatest would be hear a comment from devs how this was modelled. But so far seems the 5-6 second value is not far from real and within acceptable limits of a game. Yesterday flew a mission in Me110C-7 and trimmed plane to get best performance. It took small inputs and even when diving the input required was small. And it did not distract from flying either,not even during landing. So I think the trim is pretty OK even with it's peculiarities.

Aside from A2A also note that Tony Bianci has been flying WWI and WWII warbirds, including various Spitfires, since 1961 and his company are also the ones currently restoring the Tempest V.

Is he contactable?
