vibration, Esky belt cp

Hi guys

I just bought me some new blades for my baby, fitted them and now they vibrate like nobodys business. Any ideas? I took them off and spun it up and doesnt seem to vibrate so dont think its the feathering shafts. Is it just unbalanced blades?

P.S. If I dont have link nose pliers is it ok to just unscrew the phillips screw inside the ball?

Hi,
Maybe it is unbalanced blades. Is tracking OK?
P.S. It is OK to unscrew phillips screw inside the ball. I always do that

thanks blades are balanced am working on the tracking. If I took off the main blades and spun it up and it doesnt vibrate am I right to assume that the feathering shaft is ok and it may just be a question of tracking?

Well, I don't know if it is good way to check feathering shaft. Better put on main blades and try to track blades. If you can't get them tracked it is probably bent feathering shaft

The way to check the feathering shaft is to remove both blades and turn the bolt/nut that holds the feathering shaft. If the blade holder wobbles, the shaft is bent. If it is a slight bend, then you need to remove the FS and roll it on a flat glass surface and check if it's bent. I get the impression that a bent FS will vibrate and throw the blades out of track.

Another culprit to vibration is a bent Main Shaft. The E-Sky MS is not hardened steel and can bend easily in a small crash.

Those are just my guesses as you indicated you balanced your blades.
