Edge FBL blade rattle?

[Bobs]

I have a set of Edge 603mm FBL blades with approximately ten flights on them. I noticed a rattling sound coming from the blades the other day when I raised and lowered the swash. If I tap on the blades I can hear a noise that sounds like something is loose inside one blade. Anyone else experienced this with Edge blades?

Its your ball links,
Just had this the other day with my radix, Take the end of the blade and twist it up and down so you put a load on your ball links, then start grabbing the links until you know witch one is loose.

Your blades are fine : )

Did you try to grease/oil your mainshaft? Mine was free of grease and I had this rattle too.
After oiling the main shaft a little bit the swash was moveing smooth again and the rattle stopped.

TRy differnet set of blades to see if it still does it. What FBL are you using? I running SK720 with Satilite and if you move the collective up and down you will see a roughness in movement and cause a rattly sound from the blades. THe blades are fine and so is the FBL unit as there no roughness/jitterly in the head when flying.

It may be the bearing in the blade grip. On my blade grips they are not a perfectly tight fit and if I raise and lower my Edge FBL blades at the tips, I can hear it rattle in the grip.

I have the same rattle in one of the 2 SAB new type blades I am running on my T500 FBL. I think it could be the weight inside the blade which may be loose causing the noise/rattle, otherwise they fly great. I contacted SAB who informed if their is no blade induced vibration just fly them.

Had the same thing happen to me!... the blades are on the noisy side but they are AWESOME!!! They fart so well!!!

I get the same sound,I think it might be resonating from the servo metal gear train and or the servo steps or system resolution?When the system is spinning I can't see or hear it.Though it's normal it would be interesting to know what it is.

It could be notchey bearings on the elevator arm ive seen that before.This is on the bench not noticeable in flight.
