Center an game controller axis

[edgreenberg]

I just bought a very nice trim wheel from Flight Velocity.  FSX sees it as an axis. 

The problem is that FS initializes the axis at the zero end, not the center.  

This means that the first time I touch the wheel, the trim snaps to full trim up.  The aircraft loops 🙂

It's a long shot, but is there anything that FSUIPC4 can do to center this axis when a flight starts? 

Thanks, Ed

I didn't know that I could loop a Cessna 172 (multiple times!)

Does the trim wheel turn continuously, or does it have stops? If it has stops there's nothing you can really do except make sure it is in a sensible place each time you close down so that it is okay next time.

If it doesn't have stops then it is more difficult. What happens at the crossover point: does it suddenly change from s maximum to a minimum value and vice versa? I've never heard of an axis with no end points. You'd probably need to deal with is using a Lua plug-in, to arithmetically convert the value you read into a value relative to the neutral point (0), allowing for the wrap-around of the value where the end stops should be.
