Hey guys wats up? just a quaestion i am going to take part in class 2 this year and i just wanna know something. I have the meatal head on the evolution with the underslung flybar i have been testing dampers lately and cant seem to fing the best set up. The standerd dampers are the white ones but the heli seems two wollow with these and its not to good on the tail movement. I tried the black dampers today and it made a big diffrence to the heli in terms of stable hover and tail movement. Could this be the white dampers are warn or are the black dampers a better choice.
Thanks alot

Dampers
It could be either, wear or durometer, but the SSZ-3 head seems to hover best for me with the 70 durometer dampers. I have a set of black 70D dampers that I think are from the SSR-V head that work really well but require a different length bolt than the stock dampers.

I got the softest dampeners for the EVO head which are white, these are the one that take the shorter bolt, but they are too hard in my opinion to get it to hover nice, it wobbles at lower head speeds. I am going to switch back to my old black dampeners with the longer bolt, or I might try one white and one black...

On paper the white 60D dampers would appear to be the softest. Not. In reality, the black 70 and surely the black 60D versions that date back to the SSR-V heads are softer.

If you need part number clarification on which is which, let me know.

Those are my exact findings. Maybe it all has to do with the longer and shorter bolt?

That's it in part, and the rest has to do the the design of the sleeve. The white dampers use the different sleeve and some kind of a different bonding agent to improve durability, plus the obvious difference in material. Jeff Green explained this to me. Hirobo kinda needs to "recalibrate" their damper numbers for these new ones versus the older ones.
