I ordered on of these damper sets. I am not sure if the two washers are just replacement spacers for the thrust bearings, or if they are used as shims between the dampers and the aluminum spacer. I have them installed as shims between the dampers, but everything seems kind of tight. I have not flown it, but after doing a search I am unclear what the finial opinion is.

Yea, I think I will agree. I already have taken them off. So my next question is what are the best dampers. I bought some trublood when they first came out. They did all right, but I think they have already worn out. I know some people were having problems with the first batch, which is what I have. So have they changed the design, or is there something better?

the washers are there to retain the damper within the block, they are designed to go between the metal spacer and the outside damper.

...Once upon a time there were Nitros, flybars and frequency pins...

Have you tried them like that? When I installed them like that it tightened up the thrust bearings so much, they were very ratchety. It didn't feel right.

Yea I run them like that, pull out slightly on each grip there is no resistance. After about 8 flights I could not feel any resistance without pulling on the grips at all, they are fine.

Does it not matter that the inside diameter of the spacer is larger than the spindle? I was worried that it would not be centered on the damper. Maybe resulting in unequal pressure.

How many flights do you have with them? And are you running the stock dampers?

You use the brass shim AND the original spacer between the dampener and the blade grip. If you need to center the brass shim in the spacer and they seem to go together. Just like OICU812 said, it flies great. I'm using them with the Trueblood dampeners. It really helps them getting chewed up by just the original spacer.

Yea, I had them both on. It just seemed to be very tight. But I may give it a try. I still have my two sets of trubloods, but they are pretty torn up.

pull out the grips a touch by hand you will see they will turn freely no notchyness, now imagine in flight the pull out force, so no real worry there. GL

I was concerned about head tightness as well. Simply file down the aluminum spacers slightly with a jewel file until perfect. Now, I can tighten both screws into the feathering shaft tight while having the blade grips rotate very free. Just don't file too much to create slop.

No need to file anything, let the dampers break in and they will be fine.

I agree. No need to file them down, You'll be fine just letting the dampeners break in. Even with the Trueblood dampeners, you'll be fine!

Yea, I was probably just being a little cautious. They few threads I found about bearings breaking, made me think twice. I am going to give it a try with the spacers and see how it goes. Unfortunately the man upstairs is doing his annual September wind tunnel experiment here in my area. It has been blowing nonstop since Sunday. So I will have to be a little bit patient whether I like it or not.
