I built my new T600E about 2 months ago and have had many wonderful flights on it since then. Recently though i have noticed an enormous amount of vibrations. I believe it is coming from my head assembly, but am not positive. I notice when i grab the Blade holders i can move the entire blade assembly very easily up and down on the Feathering Spindle. This leads me to believe that my Dampers in the head block have gone bad, but they are barely a month and a half old and i do not fly any 3D. I am only doing basic Sport Flying and Autos. So whats the deal why is this happening and do you think this is what is causing all the vibrations??? i don't want to put the Black 3D dampers in cause i am afraid it will be too reactive with them, and i like some play in it, i like for it to fly a little more scale like and not very extremely sensitive. Anyway anyone that can help or have any idea would be greatly appreciated. Thanks

What did you lube the the dampers with. It should be non-petroleum.

You could just replace the dampers with stock- the black ones won't really fly much different so don't be afraid. I am running the black ones and for some reason this set is lasting a good long time- previous sets got very loose in a relatively small amount of "3D" flying. I use silicone grease (from plumbing supply, for faucet valves) on the spindle and dampers.

You could also consider aftermarket dampers like K&B Dream Designs, or others.

I don't really think you'll find that good tight (but not overly stiff) damping makes the heli more difficult to fly- on the contrary it makes it more predictable and positive in response to control input.

Never, ever, ever, ever give up.

So in all of your opinions, do you think it is the loose dampers that are creating all the Vibrations? To answer your question heli770 i actually did not lube the dampers. i don't remember anywhere in the manual saying to do this so i did not do it. Would that be causing any problems? Is lubing the dampers a must?

It makes it easier to install, and when you first spool up it will center the feathering shaft.

alright thanks guys. I will get some lube and install the Black Rubber Dampers sometime today or tomorrow. Hopefully this solves my Vibration problems, cause i can't move forward very much with my AP Rig for the 600 until i get these vibes figured out and fixed. Thanks again
