I have 2 raptor 30s with os37s maverick 550s and 401s. I fly them all the time with no problems. I just upgraded both with green paddles and red dampers and now they both have a pretty good side to side wag when I fly them, not all the time but on spool up and going into a hard turn or into and out of a flip. It seems like it has to do with headspeed, but I can't get anymore from the 37s and I also tried adjusting the gain on the gyros. Yes, I did grease the dampers. What bugs me is they are Both doing it. Help please!

- Balance issue?
- Blades have been balanced and have same C/G?
- Fan balanced?
Flybar balanced?
- Paddles are at matching pitch?
- Flybar measurements identical on either side of the head?
Fan balanced? (Maybe not quite as critical as the other two..)

If all else looks OK there, you should be able to adjust your throttle/pitch mixing curves in Idle-up to perhaps get a higher headspeed at a lower collective pitch (within the limits of what the engine can provide).

Harder dampeners wobble at lower head speeds, chances are you are just loading the blades and slowing the head down.

Did you grease them well when you installed them?

Yes, I used some silicone grease. How do I get more headspeed?

are you using a gov??? if so adjust it to get a higher headspead...
otherwise increase your throttle curves....but have somebody tach it...

There's only a few ways of accomplishing that: Increase power, or decrease engine loading...

More power:
a) Higher nitro content fuel, up to a point. If you're already using 30% nitro, adding more won't necessarily boost power that much.
b) Run leaner. (not recommended!)
c) Get a bigger engine. :-)

Decrease loading:
a) For a given point on your pitch/throttle curves, decrease the pitch of the main blades but use a higher throttle setting. Higher pitch = more drag = more engine loading.
b) Use shorter blades.

I'm sure there are others, but these may be the most practical means of increasing headspeed (mostly, use less pitch, or more throttle - I'm assuming you've no more throttle to give or you wouldn't be asking!)

No gov on my 30s, they don't need them.
