So the black ones are for low headspeed and are normally for the 2010 head,

And the white ones are for hardcore 3d and normally for the 2009 head?

Is that right? So you guys think I gonna notice a big difference here?

The black bushings were used in the "wobble" head which is why you have play in the feathering shaft in your video. Think this was to make low headspeed flight smoother? I've only ever used the black bushings so can't tell you if moving to the white bushings will make a big difference. I'd definitely like to try the white bushings though.

Yes, HR-3, 120 degrees.

On the next tab in the wizard, check that your cyclic is +/- 10 degrees. If too sensitive, you can also try reducing the cyclic travel a little, but I would try reducing the rotational speed first in the Advanced Menu>>>Setup>>>Cyclic>>>Rotational Speed.

I think it sounds very unusual that you went to -50 on the Input Exponential in Brain2 with no effect. Check that you have a linear curve in the 18sz Tx AFR for the aileron and elevator when adjusting the expo in the Brain2

Hello

I've found the problem. The bushings made the difference. I had the Brain settings still on the testing number when I posted 2h ago. So ive changed that to the default settings. And bam it feels alot better now!

But it sound and feels like there is a little of blade tracking or how do you call it in English.... but when I check 0 degree to pull the 2 blades to the back its okay. also with the pitch gauge its good. Is it possible that there is blade track only in the air ? never got that problem but maybe its possible ?

Best regards Joeri

I've had a similar problem when one of my grip arms was slightly bent. Ok on the bench but didn't quite seem in track in the air. Took a while to find it. Of course there's always the old bent d spindle

Hello,

The spindle is perfect because it's new form Jan but with those big bushings and those high headspeed maybe bent the spindle?

How to check the pitch arms?

But when the pitch arms are bent you see it with the pitch meter? Or not?

I'm only recently getting half decent at figuring some of this head stuff out. With the bent arm you don't pick it up with the meter. You compensate with the link length so you might pick it up via differing link lengths between the two grips. But if you're looking for it it should be easy to eyeball.

For the spindle you turn the bolt 360 degrees on one side and watch the opposite grip for movement. Took me a while to understand how that worked. I used to watch the other bolt for off centre movement which is much less accurate and difficult to detect because of the washer being off centre to begin with.

The spindle is okay the linkage lenght are also not much different from each other in my opinion.

1 is 48.1mm and the other is 47.9mm outside dimensions

If you measure pitch on the blade itself, ie nothing wrong with the grips, the only thing left I can think of is a difference in the blades like CG or it's back to the bushings and maybe they differ between the grips. I've had something loose before on a grip which caused the same effect.

Another idea is to compare pitches between blades at hover pitch e.g. 5 degrees if you haven't already. One last thought is the grips are not symmetrical distance wise from the main shaft which would also give vibrations.

I've done a new flight after setting up the heli again definitely without blade tracking.

After the flight 0 looks like this

So there must be something bent?

I see and hear it also in the air

I get a package from Henseleit tomorrow and normally with all the shafts new. So I start with the spindle an check it again but normaly this is already a new one. So it's strange that there is only tracking in the air and on the ground with pitch gauge nothing.

I think I've found a other problem again, but again my own for I think I need to rtfm (read the ****ing manual)

I've found that if you change to the white bushings you also need to change to the red dampeners so let's do that first before try to change the spindle

Go to the white bushes and a red "O" ring on the inside and a Black "O" ring on the out side, also change the blades, Zeal are not good on a TDR, TDR's need a more neutral blade, XBlades X693 or X702 are perfect, NHP 700mm and Radix are all great blades for the heli.

By the way what headspeed can you get with the Scorpion. I find that with mine even with the 15 teeth pinion on the motor I get barely past 1700 at 80 % on the Tribunus.

Hello,

I've no idea I can't measure the headspeed I don't have a tool to do that.

Looking forward to hearing how it goes.
