I was curious about the issues people are describing with changing the function of the stick motion, so I tried on my Android phone. The resulting video is with the RC ON and connected to the phone. The results show that you can only change in pairs and you you can only move the actions by 90 degrees at a time instead of just flipping them 180 degrees. Half the video shows flipping ascend and descend, but then left stick motion results in right turn and the oppose for right stick motion as well (left turn). The other half shows switching "Custom" back to Mode 2. The white dots you see on the screen are where my finger is touching the screen.
