Hello Tomas,

I want to the display the head speed of the main rotor (RPM) on my JETI DS-24.

My equipment:

- Transmitter JETI DS-24 with Spirit integration
- Diabolo 550 (pinion 20 teeth and gear ratio 1:9,88)
- ESC Kontronik Jive 100+ LV
- Motor X-Nova 4020-1000 (Minicopter Edition)
- FBL Spirit Pro (firmware up to date)

You have once told me:



With Gear Ratio 9,90 I get the wrong readout on my JETI. With Gear Ratio 3,30 too. The headspeed it shows on the display is wrong, it is too high.

Thank you!

Chris

Hello,

how you have configured Sensing Divider?

Hi,

thank you.

I have set it to 4.

8 : 2 = 4

IMHO everything is set right. RPM shown is still too high.

I use the App HeliTach to control it. But maybe I will buy special equipment too to measure. But IMHO HeliTach measuring is accurate enough.

HeliTach shows 1800 RPM. This is plausible. But Spirit messures over 2200 or something. What Spirit shows, is not totally nonsense, but still obviously false.
