MikeInMobile.... You flipped the whole washout base? How did that work out with the brass sleeve extending 3 times or more out on one end? Right now with the short end of the brass up, its near touching the block at full pitch.

Hellimat... Im using new HS65MG servos on cyclic. The heli has less than 20 flights so I doubt its worn parts but having dealt with align quality before it could just be bad parts.

The older washout bases are symetrical. Flipping the washout base allows better clearance for the pushrods. I have the following head mechanics setup:

Duzi Swashplate
Align washout base (HS-1143)
MicroHeli Washout Arms (MH-TX4183ARM)
MicroHeli Flybar System (MH-T4172)
MicroHeli CNC Head

This setup gives you the ability to change all of the flight parameters easily.

Oh ok. I'm not looking to rebuild the head The washout base on the V2 has three times more brass on the bottom so just flipping it will not work out. I will just have to live with it for now

Dead zone ( Due to washout?)

The_Widowmaker
Allow me to drop in 2 cents.
How many flights on this washout? I'm sure you are applying a drop of oil on occasion.
That looks like to much play in your washout. Pickup a plastic washout and remove the bushing/bearing and repair your metal washout
This will remove most of the play your washout exhibits.
Or try the plastic washout for a comparison.
Regards


Here when wanted.
There when needed.
Everywhere when looked for.

Try a different set of blades first of all just for fun - With my small helis I've found different blades will either mask or exagerate head slop - One set will flop and flutter pretty badly but another set will be silky smooth with no sloppy characteristics at all (must have to do with the shape and/or cg of different blades i guess)

It has less than 20 fligths and yes I have oiled lightly. This is my second V2 and the first was the same way. The play is in the swash bearing.

Ok I did the grip flip. It requires flipping quite a few components including flybar cage, washout base, and all the arms. Also moving the balls on the upper arms from one side of the arm to the other....

....and yes it was well worth it. It eliminated the dead zone I had as some of you said it would and it seems a bit more crisp but I will not be able to really try it out until tomorrow..

For any others that want to do this its very simple. The brass collar in the newer washout base (New V2) taps out very easy. You tap from the short side of the collar because the longer side is actually larger and ridged . Coat with a little loctite and insert back in from the other side.

The term is Transitional Delay! I did the flip the 1st month into the rex way way back. I finally had to replace the washout base and slipped it onto an old mainshaft and ground the excess lip off the base for re-installation. Don't forget the older design didn't have the offset bushing. The other item in the head needed to remove the rest of the slop was some MicroHeli washout arms with the bearing nuckles. check gallery

Lamar have you pushed on the ball ears of a plastic swash?
