My friend and I both have Mavic Pro's. He crashed and damaged his camera. I replaced the camera and gimbal. It works! So he calls me and tells me that his MP will not go over 4 mph. I tell him to turn off beginner mode. So, he gives me his MP to play with to see if I can figure it out. It will fly at 4 mph forward but 7 mph sideways and backwards. I checked all settings, recalibrated the remote, compass, and IMU just for the heck of it. I saw a video on YT saying to turn on beginner mode for a few seconds then off, no help. See, it will go slow but I can fly any distance up or away and not the 98 feet in beginner. I have zero warnings coming up and it fly's exactly as it should in sport mode! Someone on here suggested logging off of dji go 4 and re logging in which I will have him try but if I use my IPhone on his it does it, switch to my MP and everything is perfect! Dji wants it sent in for repair but I'm hoping someone on here can help!
