on my 600xn nitro when in the air there is a high pitch squeal is this normal or do I have an issue
Good call by Geena. Make sure to regularly lubricate those gears because they can overheat and melt their housing causing the gears to grind their way through the side of the frame.I could be wrong here, but I think that squeal you`re hearing is that three stage geared transmission they put on that model. I hear a high pitch whining sound on every flight video of the 600XN I have ever watched.
