Hello,

piruette consistency is very dependent on Pirouette Consistency parameter.
But generally if you have to use low tail gain, it will not work well with any value.

For tail motors it is better to start with the lowest Pirouette Consistency and the highest tail gain that is possible without an oscillations.
Then increase pirouette consistency if pirouettes are not consistent by 10 for example.

In our case with provided settings it worked pretty well also in hard maneuvers.

Tomas, it is really not easy to check / compare paramters when there is no tool to read / compare settings.
I know the viewer is not on your priority list, but for analyzes this will be the key to do the comparison correctly.
Currently viewer is not able to read SRXL2 receivers nor it is compatible with 3.2.2 parameter sets.

Attached please find my settings, hopefully you can guide me to the parameters which really need to be changed.

I'm sure there is one mismatch in settings, easy to change, but currently not visible to me ;-)

Will there be a change that all - still pending - motor tail related issues will be solved or improved in the upcoming firmware version ?

Hello,

I checked your settings and found that Pirouette Consistency is extremely high.

All motorized tails should rather use low value, otherwise it cant work properly.
Please set value around 80, this should resolve the problem.

Then Rudder Delay configuration to around 25 could be needed too.

We are getting pretty good results with current firmware, so I guess it will be only parameter issue.

Hello,

My name is Maik from Germany and I bought an omphobby m2 heli last year to practice.
With the settings and programming of the fbl system I have my problems.
Since I already have a spirit gt in my 700 scale heli, the m2 should be converted to the uSpirit. I have already pulled a lot of info from daniel-i his thread.
I am concerned here with the pin assignment of the omp esc. I once made 2 pictures of the esc and created a cable / pin sketch.
Please, is that so correct?
Regards Maik
