May 9, 20242 yr Has anyone tried and had success with converting and using a simple USB volume knob as trim wheel in MSFS?
June 16, 20241 yr Author I did it with AutoHotKey. Remapped this guy: USB volume knob with this script: AHK script
June 16, 20241 yr Very clever. Can you change the rate at which the trim moves? Also, does it “reset” to the current position after the autopilot is disconnected? AMD 9950X3D | 64 GB RAM | RTX 5090 FMR: 747 FO, 757/767 CAPT, 737 Check Airman Current 777 CAPT
June 16, 20241 yr You can do it with Lorby's Axis and Oh's. Assign Mouse_Wheel_Up to the ELEV_TRIM_DN event, and a similar action for Trim up. A reset is not necessary because you are not using an axis.

The knob I have has detents when I turn it. A signal is sent with each detent. I have remapped it to send Numpad + and - depending on the direction of rotation. I think it should be possible to change the rate e.g. by asking the AHK script to send multiple keypresses per detent. I fly the A2A Comanche and it has a control in the tablet for trim rate. Wrt. reset it is not relevant with this approach… the knob does not know ‘where’ it is. It rotates infinitely in each direction. As mentioned it is not an axis.

June 20, 20241 yr I have a bonified Cessna Trim Wheel, but I don't use it for trim as I prefer two adjacent buttons on a TM Boeing TQ. I like the fact you can do incremental adjustments or hold down either button for continuous adjustment. I use the trim wheel for nose-wheel steering and recently also mapped it to rudder axis as I don't use pedals and works quite well in this scenario.

June 20, 20241 yr Author Yes, the button solution also works well. That’s what I primarily used until I remapped the volume knob. Must admit that the smooth rotation and tactile feedback from the detents makes for a good feel. My yoke also has a rocker switch set up for trim, and I use an old USB numpad as button box and it’s also easy with AHK to remap keys or run macros as needed. Didn’t think about the rudder option, but I will experiment. I have no pedals either.
