Default So I put my new carbon fiber blades on...

and it's stable during spin up but when I get it in the air, it wobbles like a...like a.... I don't know what but it's certainly not flyable. I have a feda dragonfly and these blades are supposedly pre-balanced and ready to mount. They didn't fit on the head (the holes were just a little too small, I mean a very tiny bit) so I took a drill and opened them up just a bit, I wnet slow and checked them after every time I saw a little shaving go away until they would slide on by hand. They are the MAH CF blades for fixed pitched heli, the ones with the funky ends...here's a pic...any help/ideas/info would be appreciated. I did check CG with with balancing them on a razor blade and CG looks good. I'm lost.

they look fine, like one blade when viewed from the side and I have it in my hand spun up full speed.

Check your fly bar for centering. You may have bumped it out of center taking the blades off and on. After you make sure the fly bar is equal lengths on both sides, spin up again. If that doesn't work, tighten the rotors down so they don't swing freely. Not super tight but tight enough so you have to move them by hand to even them out. Then line them up by sight, spin up and see if that stops it.

sorry to say but I perfer the MS FP hornet baldes ..they have less pitch and therfore give you more head speed ..but you need a 370 motor in your bird .

WEll I put the old blades back on and it seems to be fine...I'm still at a loss, but I'm going to get actually flying the thing down pat before I try to re-install the cf blades...its' just weird because when I spin up with the cf blades, it doesn't shake at all, but once I"m in the air it does the "dance" maybe I should put a video of it up. anyways thanks.

How big is the area your flying in?
It's not due to extra wash / air disturbance is it??

no, it's definitely not that...it's something mechanical...
