I just looked it up and the red hard dampers are the same part# for the hawk Pro as well as the Raven, although the Hawk uses a 5mm feathering shaft and the Raven uses a 6mm feathering shaft. Now how can one set of red dampers fit both the Hawk and Raven when they both have a different size feathering shaft?? This is where the problem is! Seems they were designed to fit the Hawk as an upgrade and way to tight for the Raven.

There are brass inserts that you use with the Hawk Spindle.

Actually, the compression of the dampers (stock or hard) is the same on both.

The Hawk Pro has special 5mm ID x 6mm OD spacers that fit over the 5mm spindle and into the dampers to effectively make them damp as though it was a 6mm spindle.

I also have installed the Hard dampers in the stock plastic head on my Raven and in the CNC CN2515 that I have on my NX50.

I also freely lubricate both the spindle and the dampers and use a socket to push them into place.

I found that by first sliding one damper to the approximate proper location on one end of the spindle, then inserting that into the hub, then sliding the other damper down the spindle using the socket to push this one into the hub.

Using this method seems to make the job a lot easier.

Yea I do it just like OF does. Only difference is I put a nut on the end so I can push on it aggressively thru the first one

Yah I used the red dampners on the hawk when it had the plastic hawk head and they fit great.
But I was new to the heli and the hard dampening was a little too much for me.
QUESTION
Maybe I'm used to electric helicopters but when I'm flying the hawk with this OS 50 and I come down low rather
fast from high altitude and pop the collective up to do a quick stop it seems like the collective hesitates.
It is very noticeable. Is that just the nature of mechanical mixed head? It has a metal gear HITEC servo for pitch
but it is pretty old.

A slight hesitation would be the norm due to it takes a slight nano second for the nitro to respond. Where as the electric will be almost instant, like (electricity). I would think a program mix would take this out on the hard stop but may overcompensate on other maneuvers.

Could also be my throttle servo. The only digital servo I have on the bird is my tail servo. All the others are old JR sport or NES something or other analog servos.

Its refreshing, here in Century land, that your response was not of the, "What, you dont think Im right? Whats your problem". I get sick of people over reacting on here.......
And, CompyMike sounds like your next upgrade is some new servos you can count on. So you know they are not the problem. Some pretty good servos out there for around $65 each. Or if you must (I dont like to buy servos used but have) a set of 3 used 9252s run around $150 in the ads here..

Just get some Hyperions Mike. You will not be disappointed with them at all. And you can get 3 of them for less than $100.

Are those the programmable ones?
Nice feature, no more going thru piles of servo arms.

Yes FBoss, they are the programmable ones. I fly nothing else to be honest. I make all my servo adjustments with the programmer. I do absolutely nothing in my radio. All my EPAs and Subtrims in my radio are set to 100% or 0.

Another nice thing about these servos, if you crash, 9 times out of 10 you will strip the only plastic gear in the servo. It is the one that comes right off the servo motor. You can buy them 4 for $2.50.

Only bad thing I have found so far.. if you break a servo case, you cannot buy a replacement. But I figure if I have crashed that hard as to break a servo case, then I am going to need a new servo anyway .
