Hi All, I'm the proud owner of a Phantom 2 and also a newly acquired F550 with Naza V2 and JR XG8 Rx/Tx. Problem I've been having is really unstable flights and also when testing out the RTH I've had 2 flyaways with crashes. I'm really bummed by this and have lost a lot of faith in this machine. I have plugged it into the assistant software to check things that many times I'm beginning to believe I may have a dud. Does anyone have any advice?
