I have not flown my P3S, as of yet. I bought it used and it appears to be in really good condition. I wanted to read, and reread everything I could about the aircraft before I took it up. I decided to confirm that the controller is calibrated correctly. When I go to the calibration screen on the app, it tells me to center the sticks then click start. I have tried that several times and it keeps telling me to center the sticks and click start. The sticks are centered, as best I can tell, as they each have a centered "detent" feeling. Any suggestions as to where I go from here? Do I just assume the controller is calibrated, at least until I fly it and see if it needs any tweaking or fine tuning ( I can't think of the word used in smaller, cheaper drones when encountering a drift or yaw issue, so I settled for tweaking and fine tuning. I an sure you know what i mean) Any and all help is appreciated.
