Is Spirit capable to do a blur-piro?

How can i make the spirit do a blur piro? just cranck up the rudder rot speed to 20?

Hi!

Yes, you can do so.
Spirit can control rotation in range of +/-2000°/s in each axis.

The question should be, can your heli do them :)

Ok, i tried rud rot speed at 20.
(450L heli 95% throttle)

i got this:

But i'd like to have this:

Can I make it do this somehow? maybe with endpoint adjustment of the radio, to have like 150% in spirit software?
Spartan does this by at the full stick it turns off HH gyro. (i was told...)

Thanks! :)

Is the 2nd video of a 450?

OK, i see your point. But:
I adjustel endpoints in the TX from 100 to 150%, now at full stick spirit diagnostics tab is way over 100% and it made the piros a LOT faster.

Now i will shoot a new video of it. I think it is capable of more, just need a rud rot rate in spirit like 25 :)

OK, here is the second vid, good part is from 1:30, it should start from there when you click it.

Still got the bounce back from right rudder, can't tune it out, and on full right rudder i got a big head wobble. Even with cyclic gain at 30% ( maybe the torque tub is vibrating under the load? )

Do you want to fly like this all the time or it is only for some testing purposes?
If so, then stopping behavior should be tuned little bit differently, because good, non delayed stops from so fast rotation is almost impossible for any servo/mechanics.
You will need just to play with tail limit to make the stop equal for both directions.
Slower the rotation speed, the easier tuning.

You can try to set gyro gain to a very low value (1%) + high rudder dynamic. This will allow the max possible rate.
