Heck wiggle at pitch pump

[sascha1603]

Today the Compass Warp 360 from the son taken and at Tic Toc determined that the stern oscillates back and forth
It is also the case with pitch pump, if you quickly short posetive and negtive pitch stös there
Han already tried more, Revo mix etc but has not brought much
What could I try? Servo is Compass 301n

Hi,

can you attach your settings? (4ds file)

It can be caused by wrong Pirouette Consistency value, high Rudder Delay.
I do not recommend to use Revomix at all, this will usually cause another troubles.

In the appendix are the 3 benches

Thank you!

First from all, I can see that there is some problem with the rudder limits.
One limit is extremely low while other is high.

This mean that the rudder neutral will be somehow off. This will cause bad performance.

First, make sure that when you enable Servo/Subtrim (tuning) the rudder servo will go to the center position as close as possible. If no, this must be corrected with the Subtrim CH4.
Then check, what is the rudder neutral position - verify with Subtrim (tuning).
It should be approx 3-4° (slider closer to the boom).

Then you can also reduce Pirouette Consistency to 165.

And also set the Revomix to 0.

Thank you
I'll test today if the weather fits
In my 7HV Ulti I have also Revo mix in it the rear with Pitch halts and it holds quite well (Heck Servo MKS HBL990)
Should I change there also what it goes without revo mix?
In fast and light pitchpump he nods slightly over nick (nose up and down)
I have the benches attached
Maybe find a few errors

Thanks in advance
Sascha

Yes, I recommend to not use Revomix at all. Only in case where servo is slow it is recommended, but your servos are good.
Also if it is really needed value of 3 should be enough usually.

For this helicopter you have to increase Pirouette Consistency to maybe 175 - 180. This will supplement Revomix that is used now.
Rudder Delay can be 0 - 3.

Thank you, I'll test
And because of the nick jog at fast and short posetive and negative pitch? with 7HV

I have just tried everything with the Warp 360
Revo mix to 0 and Pirouette consistency down to 165 (have also tried 150, 155, 180 etc.)
If I hover and give a short pitch bump, the heck is about 15 degrees to the right seen from behind (nose to the left)
In the flying itself one notices nothing, with tic toc one notes it clearly and if one puts him on the back and he easily goes through the heck also a jerk
Even if you drop it with the hover and catch it comes the rucker and the rear turns away
What else could I try?

[sascha1603]

Now everything fits
The servo horn was too short, 9mm instead of 12mm
The rear holds now bomb synonymous with tic toc
