I have a HW 100A V3 with red Spirit, firmware 2.0.0., FBL governor enabled. When I activate bailout during autorotation, motor kicks heli really hard - too fast for my taste (not good for TT gears on my TRex 500). How could I make it a little bit slower? Any settings change?

In gov setting, there is the parameter spoolup rate, use a slower setting there.
Bailout is aprox 1/3 of normal spoolup.

You may also need to reduce your lower throttle endpoint. You can test with the blades off.

I`m already on slow spoolup in governor menu. Where must I reduce lower throttle endpoint?

Increasing Max. Head Speed value will help with the problem.
You only have to decrease TC in your transmitter to make Requested RPM same again.

As per Mr.Mel headspeed calculator:
(calculated for 100% throttle curve)
Hover RPM at beginning of flight: 3377
Hover RPM at middle of flight: 3110
Hover RPM at end of flight: 3002

Now I have 3000 RPM Max Head Speed in the governor menu, how much shall I add to this number?
I do not want to go higher than 2700 RPM in flight.

Use 3377 as max HS and use an 80% throttle curve.

Shall I leave slow spoolup or change to very slow?
And what Hz should I run with HW 100A V3, now I`m on 60 Hz in governor menu settings.

Tomas tested 200Hz with no problems as he said. See below.

Just out of interest, which mode do you use? Fix wing or heli gov off?
I'll get my HW 100A v3 in 3 weeks to test all the settings and for sure I use bailout from spirit to share here.
