Is there logic behind why some planes have the trim axis reversed?

I use a Thrustmaster t16000 and twcs setup, and use the wheel under my left little finger for trim (it's an axis rather than a rotary encoder, unfortuately). Most planes have the axis in one direction, but some (Milviz Porter and FreedomFox being two that spring to mind) have it reversed, meaning that I trim down when I'm expecting up and vice versa. As you can imagine, this leads to a few interesting moments.

I know I can reverse the trim axis in the controls setup, but that's a global setting. Is it possible to have plane-specific reversed axes? Any other options to solve?

Make a different profile for each plane.

Certainly an option, but if I'm going to be switching between profiles, I might as well just toggle the reverse axis checkbox.

I take it there's no option to tie a profile to a plane, such that the profile changes with the plane loaded?

Try FSUIPC. I set different profiles per aircraft (group). Not sure whether profiles are available in the free version (I have the payware version) but worth a try. FSUIPC is a great tool anyway.

Shouldn't have to do that. Roll the trim wheel forward = Nose goes down. Roll the trim wheel back = nose comes up. Simples.

You shouldn't have to make a profile to correct something that is wrong. If you had an aircraft that nosed down when you pulled the stick/yoke back and vice versa whould you be happy to 'just make a profile for it? I suspect not.

Indeed. Whilst it's not the end of the world, I'm quite interested to know the reasoning behind this. One would imagine that deviating from the expected behaviour would require a reasonably good, well, reason. Thus my interest in the logic behind it.

My guess and it's only a guess, would be that the trim wheel as we know it, i.e. the Saitek one, isn't on many people's radar any more. I reckon most folks use buttons which work correctly. Also the Honeycomb throttle has a trim wheel doesn't it? Maybe they put it in back to front. So at the end of the day hardly anybody notices. Who knows.

We corrected the FreedomFox, an update will go out soon.

For the record this only happens when you have input axis for Trim, we noticed when a trim axis is enabled, the input is reversed trashing our custom code. We notified Asobo who is investigating.

In any case I put corrective measures until Asobo revert back with their findings. But it feels to me as a bug with the inputs of the sim and I was very surprised, this seems to start from SU5, so I would thought most 3rd party developers would have alerted Asobo about this when it occurred, but I believe (given their reaction when I reported it) this is not the case.. Who knows..

My understanding is that the Honeycomb wheel is basically a big rotary encoder, rather than an axis. Haven't got one, so can't confirm.

Many thanks for the update. Personally I'd much prefer the axis on my throttle to be a rotary encoder. Would avoid this issue, as well as the irritating factor of the AP having changed trim for you, then there's a big discrepancy between your axis and the current setting once you turn off the AP.
