Hi folks. I need help understanding how to bind aileron trim. I have a Honeycomb Alpha and Bravo. I bound a button to Aileron Trim Left and another to Aileron Trim Right. But they don't seem to be doing what I thought they would. I see in the sim that there are also aileron trim bindings that are an axis but I wasn't sure how an axis would be used since I didn't see one that was like -100 to +100 or something like that.

Can someone please help me understand how the aileron trim is supposed to work and how to best bind controls for it?

Thanks all.

While hand flying are you correcting for roll?

Which aircraft are you flying?

I am flying the Bonanza G36. I am still very new to flying. I am certainly trying to correct for roll but sometimes the plane wants to keep going left and I want to get it flying straight without so much work with the yoke.

I tested the Bonanza G36 aileron trim and it is working (MSFS2020).

I have the trim assigned in FSUIPC and in MSFS2020 while using Saitek Yoke buttons.

If you manually use the trim wheel and mouse button in the VC cockpit does the aileron trim wheel move?

Edit: Mouse select CW or CCW arrow then Clicking or holding the L mouse button?

In Bonanza only the Left mouse button is used on my testing.

If you use your assigned yoke buttons does the trim wheel move?
Clicking or holding the assigned L/R button down?

Found this:

The Beechcraft Bonanza G36 does not have a dedicated, cockpit-adjustable aileron trim wheel or crank. Instead, it utilizes a ground-adjustable aileron trim tab located on the trailing edge of the left aileron, designed to be adjusted by maintenance personnel to counteract constant flight imbalances rather than during flight.

• Adjustment Method: Adjusted on the ground by technicians.
• Location: Left wing aileron trailing edge tab.
• Purpose: To make the aircraft fly wings-level in normal cruise without constant control pressure.

The elevator and rudder do have cockpit-adjustable trim systems, but the aileron system is intended to be set once and left alone.

 

 

Seems like this may be the explanation of why I am having so much trouble with it. The G36 does not have an aileron trim wheel. Seems logical but not sure. What do you think?

Did you check the MSFS's Bonanza G36 Aileron trim wheel as I previously mentioned?

I apologize for not understanding but from what I've read there is no aileron trim wheel in a G36.

Beech G36 Aileron Trim is present and is working in MSFS (screenshot).

Have you tested to see if it is moving (turning CW/CCW) on command in your setup?
This is only a 30 second test prior to taxi or takeoff.

Note:
There is also an Elevator trim wheel.
Is it turning on command in your setup?

Edit: Both trims must be checked for correct setting prior to takeoff.

Yes the aileron trim wheel turns (extremely slowly). But I don't see any movement outside the plane. Perhaps that movement is not modeled? I say that because my elevator trim, works fine but from an outside view I don't see anything moving there either. Is there a way to adjust the speed in which it moves? Would I do that by changing the sensitivity settings to be more vertical?

Ok, great.

You have a working Elevator trim.

Do not worry about outside view.

We are not flying and testing right now.

It does move very slowly.

Did you test Elevator and Aileron trim wheel movement with just the mouse and not Yoke buttons?

 

To correct for drifting right or left, usually rudder trim is used instead of aileron trim. 

In msfs, any command assigned to a button can have 'repeat' on or off. Also, you can assign a command to require two buttons to both be pushed simultaneously to trigger the action (such as for instance Control-Y requires the Control key and the Y key to both be pressed).

So I do this for both aileron and rudder trim (Warthog throttle has 5 toggles at the top right, and 3 along the bottom): I use the top 2 toggles for aileron trim left and right. I use the middle 2 toggles for rudder trim left and right. The repeat box check is OFF for all 4 of those. So flipping any of those 4 toggles induces a tiny bit of trim and then stops. This is for the final adjustment.

But msfs controller GUI provides two boxes for any single command assignment. So I also put another rudder trim R and L and also aileron trim R and L onto those exact same four toggle switches, but combined with the 5th toggle switch. But these have the repeat box ON.  

So to trim, I flip up (on) the bottom toggle and then trim aileron or rudder continuously with one any of the other 4 toggles to get a rough trim setting. Then I flip that bottom toggle down (off) and do the same with any of those other 4 toggles to add a tiny bit of trim, one step at a time, that holds the course almost perfectly straight.

But really as I wrote at the top, only rudder trim is normally necessary.

Yes, both work fine. Using the mouse I can certainly move the aileron trim wheel faster. I am thinking that perhaps the experience I have been having lately with the G36 banking severely left for no reason I can ascertain may be something more than just needing aileron trim. I did do a recalibration of the controllers in windows. The problem does not always occur. But sometimes I will be flying and suddenly the plane just want to bank left pretty steeply when I really didn't change anything. I am a real new flyer, even though I have had the controllers and sim for a while now. Still just learning how to fly though.

The  Beechcraft Bonanza G36 does not have rudder trim.

In real life, a simple and unlikely to fail trim mechanism would be my choice for first solution. And only then to possibly move on to other solutions or systems from there: riding the pedals or an autopilot.
