I ended up making one. I used this video as a starter:
I choose to use a ten turn 10K potentiometer and a joystick circuit board. The pot was connected up as a joystick axis which you can assign to the trim axis in the simulator.
What I like about a ten turn pot is it almost perfectly matches the amount of travel you have on a real Cessna 172.
I had the Honeycomb Bravo on order and realised it was overkill (and the size didn’t work for my environment) so went for the multi panel below which brings many other useful things too.
The scalar for the trim wheel still needs to be adjusted as at the moment you need many turns, it has been acknowledged by @Tr1cky (from Logitech) to be fixed in a future driver release.
I don’t own one of those Flight Velocity trim Wheels but from what I read it does not use an axis. Movement of the wheel causes up / down trim button activity, like what you might map to a yoke rocker switch. Frankly I prefer using a joystick axis for trim, I think it is much more realistic particularly for aircraft like the C172 where the trim tab is directly connected to trim wheel with a cable.
Worth a punt, the Saitek/Logitech trime wheel if you can find one cheaply, but the Logitech Multi panel has a trim wheel too and the functions afforded by the rest of the box makes it a bargain. I have both and the wheel is first choice, but the panel is superb.
While I have a Saitek Cessna trim wheel from many years ago (Before Logitech bought them out and discontinued it), my son was looking for one so I bought the mini trim wheel from Desktop Aviatior, https://www.desktopaviator.com/Products/Model_2700/index.htm and then built a housing for it and gave it to him last Christmas. He says it works perfectly in MSFS.
I am tired of trimming with joystick buttons. It’s so awkward and frustrating. I’d really like one with a wheel or slider that can be linked to the trim axis.
But it’s very hard to buy one that’s ready made. Saitek used to have a standalone trim wheel but that’s not even available on Ebay. Honeycomb Bravo Throttle Quadrant has embedded a trim wheel, but I heard it can only be assigned to trim buttons, not axis. Will that be a big problem? Can any of the sliders of THRUSTMASTER TCA Quadrant be used as a trim wheel?
Are there any other commercial choices out there? I can’t DIY and I don’t have the time.
Thank you for any suggestion in advance.
I bought the Bravo for the trim wheel and “in my opinion”, is no better than using joystick buttons. As a simmer with a PPL the lack of a realistic elevator trim is one of my biggest frustrations with this sim/game. I have finally given up and am using the Altitude hold on the Bravo auto pilot even though for me it is cheating as I have never used an auto pilot in a Cessna 172
Thank you for the opinion from your experience! I was so attracted by the Bravo for the trim wheel, but I mostly fly Cessna myself so it’s an overkill. Now that its trim wheel is not very good I will be more likely to give it up.
I was considering the Flight Velocity trim wheel, but realised it simply sends incremental “trim up / down” commands every few degrees of rotation, so that put me off big time.
Ended up building my own instead. (Not really recommended as it takes tons of time, especially since I just had to motorise it as well)
I would imagine that it used the buttons too rather than an axis. I don’t understand why HoneyComb could not have used an Axis 7 for the trim wheel rather than assigning buttons.
on that note - has anyone found a good solution for trim in the game? it’s probably my most frustrating “flight” issue right now…
I’m using the “electric trim” switch on the Alpha and it’s super jerky - like: nothing, nothing, nothing, 10 degrees nose up!!! Makes it hard to fly smoothly or make minor adjustments.
XP11 is smooth on trim with the same hardware. ( and I think P3D was as well, but it’s been ages since I’ve fired it up )
With the Alpha and Bravo you first you gotta solve the acceleration bug issue and then the Bravo trim wheel is fantastic to use
Before I got the bravo I used one of the black toggles on the Alpha yoke and that worked great too; smooth as so I think you guys that are having problems are suffering from the acceleration bug from caused but the Alpha/Bravo rocker switches that always stay on
