Hi,

great, thanks for info.
If it works backward always, you can check, if the swashplate is level when your collective pitch is at the highest position (full collective).
The best is to measure deviation with a cyclic leveler. Also you can make sure that CG is correct.

before the flight I checked that, and did servo travel adjustments with a leveler at full collective and minimum collective. also at 50% it was correct.
When I land the heli and tried the rescue the swash goes backwards almost at full.

what do you mean about CG ?

Thanks for the info.

CG - Center of Gravity.

It seems that piro optimization is really reversed. In this case it will affect flight performance too.

There are some videos:

It is actually same parameter as in Microbeast:

It seems that vibrations are coming from the tail (the highest spike).
Second, lower spike, is coming probably from the autorotation gear.

This level is very, very high, so I do not recommend to fly with it until resolved.

First from all, if spike is not that high without tail blades, then it is possible that they are unbalanced, or problem is even in tail grips or tail shaft. So I recommend to unmount these parts step by step and check always how it affect vibrations.
If you will notice big difference, then you probably found the problem.

Hi

I flew the heli with this graphs and for my, flyes Ok, i am not an expert, so maybe is not so good, but I do not know.
Rescue works great too....

the only thing that i need help is in the tail wag at idle up 2 that is 90% flat curve.
In normal and at 75% goes fine, but in 90% start to wag.

thank you

I am afraid, but with 90% vibrations are most probably even higher that it is in mechanical limits of the helicopter to work correctly.
These vibrations may even unscrew all screws, so you have to be very carefull with each flight.
