Head dampeners

[Tom Burgess]

Ive got 12 tanks through my 600 now and the last couple the head started feeling a little sloppy. I just took the dampers out and one is much more compressible than the other? Why is this? I just ordered some KBDD dampers as the stock ones are crap anyway but I just found that strange?

Only time i have problems is with V-blades, most of the time they last quite well, my 700's have just been changed after about 6 months

They are definitely shot, just weird how one has gone before the other

Should of mentioned, they are the new one piece dampers.

Maybe you keep flipping the same direction?

[Holst]

I think once one had become slightly softer than the other it will move more than the other, as its moving more it will wear more quickly.

Yes, I have a favourite blade to lead with

The one in your avatar Tom.

No wonder its knackered.

Not had the new one piece ones yet but using the tube/hards.

I would guess one blade is pulling the blade grip ascross to one side at high H/S compressing the opposite dampner. I've had a packet of overlong Spindles where there was a difference in length of about .5mm or more

I now shim up the lot till the blade grip bearings are just getting notchy and when pulling very hard on both grips simultaneously they JUST free off. It wobbles like a good un under 1800 for some time but eventually settles. Must be 200+ flights a set

With the long spindles I used two of the shims that goes between the blade grip bearings

hope thats of help
