Hey guys, I have a problem with my phantom 3 standard, in about 1 in 5 flights the drone will fly forward at full speed without my controller, ending in numerous crashes, upon further investigation, I found out that the problem is the controller thinks that the forward throttle is at 85 percent when nothing is being pressed, has anyone else encountered this issue and does anyone have any ideas? I have tried to calibrate the controller multiple times to no avail and I'm seriously running out of ideas.
