I did not find any option to select buttons or axis, but I did discover that in the calibration step, with the flap control starting out in the midle posiion, led to recognition of the three position flaps. With it, I was able to land the 60-sized Spitfire quite easily. With full or no flaps it can be quite challenging. Thanks opjose, for the help. Several tries with the Horizon help, did not help at all.I am anxious to install version 5. We use Phoenix in a University Club setting, and start newbees out with the simulator, advance to buddy-boxed embers, and frequently have students solo within two hours. We fly inside a large multi-purpose building twice a month.
