A2A aircraft trim question

[Neil Culverhouse]

Quick question about the hardware trim with A2A aircraft. As far as I can work out, the hardware trim option in the Brunner software removes the pressure you are putting on the yoke, so you pitch the yoke to maintain your desired attitude in sim and the use the trim buttons to remove the pressure and keep the yoke in that position (this is how it should be in real life).

However, this option does not seem to send this information to the sim, so that the trim gauge in the the sim does not change. Basically you are trimming your Brunner hardware, not the sim aircraft. This causes autopilot issues too.

If disable Hardware trim in the Brunner software and use the buttons on your yoke to send trim commands to the sim, it does trim in sim, but your Brunner yoke works as if you are trimming an aircraft with a trimmable horizontal stabiliser. This means that you are trimming to return your Brunner yoke to its mid position (which would be fine in a 737, but not a Comanche or Aerostar).

Has anyone worked out a way to trim correctly in A2A aircraft?

Hey Neil, I created a proxy that sits between the sim and CLS2Sim and rewrites data packets based on Accu-Sim variables to make the AP and trim work. I use software trim, though.

https://github.com/aurel42/ComancheProxy/

It works for me.<tm>

Since CLS2Sim uses a simconnect.cfg with multiple entries, I just added my proxy as the first entry. If the proxy is running, CLS2Sim will connect to it, if the proxy is not running, CLS2Sim will connect directly to the sim, as usual. I would add support for the Aerostar, but I don’t own it yet.

Hi Aurel,

Thanks so much for this. Sounds like just what I need. Unfortunately I have no idea which item in the github library to download and what to do with it.

Is there any chance you could talk me through some brief instructions on how to get this working?

Thanks so much,

Neil

Hey Neil,

currently, only the source code is available on Github; you would have to compile it yourself.
I’ll try to build a version on the weekend that you can just unpack and run. Stand by!

Hmmm. The forum “ate” several of my attempts to post this. Probably because of the links. *shrugs*

flightsim.to (at the time of posting this, it’s still pending approval, so this link might or might not work)

Documentation: github dot com /aurel42/ComancheProxy/blob/main/README.md
alternative download (no login, no ads): github dot com /aurel42/ComancheProxy/releases

Sorry for the IKEA-style links (you have to assemble them yourself).

Let me know if it does or doesn’t work for you. You’re probably the only other user. 😀

Cheers,
Marc
