Fun with Yak54, but issues...

[Planehazza]

Hey all!

Just flew 4 packs on my RC Factory yak 54 today, was insane fun. This is my first 3D plane and my first real outing with it (only had a couple of packs on it in high winds) so I had good fun stick banging. I was doing blenders, KE, hovering, harriers etc! Was quite chuffed with myself [IMG]http://static.rcgroups.com/forums/images/smilies/smile.gif[/IMG]

Anyways, I'm having a bad noise/vibe problem. If I go above 50% throttle, the plane gets really noisey, as if the air on the prop is really turbulent. The plane also vibrates when it happens. This has happened with two different motors (2217-16 and a 2213-18). I'm using a 10x4.7SF prop which seems to be balanced (I've tried a couple and the problem is apparent with both. Any ideas? Try a different prop (any suggestions?) or a dodgy thrust line?

Lee if you see this, perhaps you could explain the sound as I can't quite describe it...

Thanks!!

try a different pitch prop and see what happens then

10x5E perhaps?

sounds like you either need a bigger prop or a corsa prop i had this with my ikarus yak when i tryed it on a 3cell pack
