I have a Saitek Quad Controller and have mapped Throttle and Radiator successfully, gut can't seem to get Mixture to map. It looks fine in the controller configuration window and I have saved my settings

In game on the heads up display I can see the indicator for throttle and radiator, but the mixture side is gray with no red tab.

I have the menu configured for auto engine start, but everything else is manual.

When I switch to the default controller config file it appears the same....i must have done something funky.

Only other problem I have is I tried to program my mouse function buttons to the Icons and Gauges on off, works fine for the icons, but can't get the simple guauges to go on and off, but even though its programed to Ctrl+I.....I think the software is looking for Right Control + I and I don't think my keyboard differentiates right from left ctrl ( does anyones?)

A couple planes have auto mixture and it isn't adjustable. The D.VII and Albatros is a couple that I know of.
Try the SPAD and see if it is working in it.

I think you have it. I was flying the albatros pretty exclusively.
Thanks
