Hi! I would like to suggest to extend the Controller Calibration process by not only asking for moving each stick to one end but to both ends. That case the software could detect the entire working interval of each stick and automatically set Trim and Scale. I always having a hard time calibrating both my controller and FPV freerider to work good together.

Yes, I will keep that in mind and possibly change the calibration in some future update.
It's very hard though since every single controller/transmitter/radio gives different output, along with all the different dongles/cables etc. and operating system that there is. So often it is unavoidable to do some manual setting up on the radio itself anyway.
