Is he talking about the do-hicky thing that slides up and down on the rotor shaft, or the do-hicky thing that has levers and push rods on the rotor head that connects from the swash to the blade grips.

I call that do-hicky thank that slides up and down on the rotor shaft the pitch slider.

Those other things on the top are called those other things on the top that connect to the blade grips. (LOL)

The "wash-out" block washes out the collective leaving only cyclic motion fed to the flybar.

"Separator" is as good as anything else.

THINGY

it's a universal term...

"You know, that thingy that goes up and down."

"Do you know that thingy that turns the tail."

"Have you seen that thingy that flies with two thingies using a thingy to control it?"

a

have you tried using the part number or pictures.

All kidding aside...
We had a Parts Manager at a major worldwide manufacturer (which I won't name) who was a woman, and nothing against them, but she didn't know a spark plug from a pipe wrench, and called everything a "doheecky" God bless her soul.

Seriously, though, the name you're looking for is a "collective compensator". As described properly by AirwolfRC, it allows the swashplate to move up and down freely, which changes only the collective, but the cyclic pushrods don't bind up because of the levers on the washout, which effectively adjusts their lengths to the proper dimension regardless of where the swashplate it in its travel.

It's interesting to compare the washout on fixed-swashplate machines such as a Zoom 400 and the one on a "regular" moving swashplate heli (Raptor, Evo, Etc.) In the former case, the pitch servo moves the washout block itself to change the pitch.

'Hope the name, if nothing else, helps

Isn't it also called a "Radius Block" or "Phase Ring/Block"? Or is that it's counter-part?

I've noticed different brands do have different names for some parts -

Does this work? - "Vaheldumine Vinkel Rahn"

Try "Pitch Compensator" hub or block. Robbe & Graupner use that term I believe.

But how about "YOKE"
Nice and thnx...

Can you suggest any similar synonym for YOKE too?

In estonian the direct translation is "kaelkoogud", and this is something the pre-historic ;-) humans used to make it possible to transfer 2 buckets of wather at once. The problem is, for some reason the word has only "plural" form, what sounds actually ok in original meaning, but is more than "somewhat funny" in that particular use.
