The dampening seemed really loose on the CP I flew the other day. How tight should it be?

I am a total noob here, what is dampening, and is there an adjustment for it?

We prefer to remove the O rings and install bearings. Now thats tight!! Its also a bit extreme.
The CP is a little soft out of the box. A couple of shims on each side helps a lot.

They are inside the head, on the feathering shaft, between the blade grips.
There is a shaft that your blade grips (the things that hold the rotor blades) mount to. That shaft, along with the blades grips themselves have a couple soft rubber O-rings right where the shaft goes into the center of the hub.

Granted this isn't a Blade CP Pro head, but close enough...
Anyhow, they are there to soften the controls a bit and the dampers can help reduce some of the twitchiness of a CCPM.

Ah thank you for that. That is what I was thinking but wasn't sure.

Replacing the O rings with bearings amplifies any balancing issues along with tracking issues. Its tight a hell but must be setup almost perfect IMO. Probably not in the noob catagory if ya ask me, which you didnt but, thats never stopped me lol.

I used the bearings that fit in the blade grips. Tight fit in my cnc head but it worked.

ya, i bet that you'll need a brushless if you want to have bearings in the head. i fly mine quite hard actually. what i usually do is get a bbq stick, get some locktite into the spindle, add one stepped bearign washer (or whatever you call it) between the oring and the other step washer, with the step facing the oring. i then tighten it with one allen wrench on the other side as much as possible until the other side turns. then i leave it at that, cuz i have locktite, i am not really worried. don't get ur locktite between teh spindle and the bearings though cuz you'll have a REAL hard time removing the head... don't ask me how i know.
with this setup, the heli do wobble at extreme collectives with stock motor because of the bogging, but i like the crisp response and i think it's more important since i'm doing 3D with it.
