Squealing Noise From P4P

[lil boss]

My friend flies a P4 and from the start it has a squealing noise. Sounds like a motor issue to me, but I'm only guessing. My P4P was quiet when I first got it. Now, after a few months and about 40 flights I have the same squeal. Does anybody else have that noise or know possibly what I should start checking. BTW my P3P after more than a year never developed that noise. Thanks for listening.. Enjoy the weekend !! Steve

Mine whines, it has only a few hours, but has always done it. Balancing props helped a bit, but when the wind hits the props, I can hear it, it seems common and just a issue of air flow.

That's a better description than my squeal.

Buy a prop balancer, eBay or Amazon have them.

There is a post about the whistle floating around someplace.
