Scorpion ESC Opto RPM adaptor to Rsen

[Thunder Fighter]

Hi guys,

I'm finally getting back to setting up my first heli running the CGY750. I know the Rsen input to the CGY supplies a voltage out for the governor sensor and from what I have been able to find on the internet the Scorpion Opto cable that is used to connect the RPM output from the ESC for the Vbar also reduces the signal voltage to 3.3v but there is no confirmation of this in the specification that I can find.

Has anyone used a scorpion and Opto cable with the CGY governor?

Chris Sexton answered this for me on the Synergy Forum. he is using the Opto cable with the CGY without problems.

Did you set it to run H pole or L pole for best results?

H pole from memory.

Trying to setup governor CGY750. Been through all the steps, all rpms match in radio and CGY. 1350/1650/1750. 130 opto with the scorp opto cable plugged into the rsen

When I spool up on the bench no blades it spools up and goes to 1950.

When I was fussing with it before I could see the rpm change closer to the set rpms in the different modes N/IU1/IU2 etc.

The sensor is working since it shows the rpm in the home screen.

I was seeing it adjust the rpms at some point previously.

confused at this point.

Figure why not try it. took it for spin..

Seemed to fly at the set head speeds.
