I just updated Air2s to the latest firmware for Smart controller and drone and now having the exact same problem, not a problem at all before update. Also climbs a little when moving left or right. I am a new with drones and I did find the moving from left to right and right to left was disabled and was working fine before. So now it works again but also climbs a little when you barely move the right stick in any direction in mode two. Seems like a firmware issue or parameters where changed with the update. Either way I am not getting a warm fuzzy feeling of confidence since upgrade.
