600 Noise

on my 600xn nitro when in the air there is a high pitch squeal is this normal or do I have an issue

We are going to need a lot more info on this. A 600 Nitro makes all kinds of noises.

Any way to get a video of the helicopter in the air? That would be the best way to diagnose this without pure speculation.

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.

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.
