I know this is an old thread, but honestly it's a life saver for me.
I bought the Logitech (ex-Saitek) Yoke and Throttle a few weeks ago and have been diving back into Flight Simming after many years away from it. After messing with the X-Plane 11 demo (my Surface Pro 2017 isn't powerful enough), and PSD before asking for my money back (same problem!), I decided to dust off the copy of FSX I bought off Steam a few years ago for £3.99 in a sale! I've been tweaking, adding the DX10 fix (amazing) and bought a C152 to fly in, and some scenery ... anyway, the Yoke works, but I could not for the life of me work out how to access Modes 2 and 3 ... after hours messing with Logitech's really awful software I finally bit the bullet and got FSUIC v4 for FSX.
Amazing stuff - yes a bit complex, but not really too complex if you are just using Mode 1. So today I kind of got my head around how to program modes by reading the Advanced Users Guide, but this above crystal clear explanation is just what I needed to get that "ahhh-ha!" moment of understanding it. Thanks very much. Many hours of geeky fiddling for the right combo in between flights awaits 🙂
