I just got an Eachine E013 drone with goggles for Christmas, and I have been having real fun with it so far. Unfortunately, all of the controls on my receiver have reversed so if I go up it goes down, if I go left it goes right, etc etc. Not only that, as soon as I turn it on it wants to go to the upper right... could this be a trimming issue? I haven't really gotten grips on the trimming on the controller. Turning it on and off doesn't help either. Thank you for all your help!
