May need some help trying to get my GOV in my Spirit GT to work properly.
I have a Synergy N5C that had a nice working Futaba CGY750 (awesome gov BTW) but can't seem to get the Spirit gov to work properly.
if anyone has any tips to give me before I switch back to the CGY750, would be much appreciated.

here is a quick run down on the steps performed

1/ calibrated throttle in the radio with software 0-100%
2/ setup gov info in software, throttle range, sensor (I have one active and one non active magnet on my clutch bell) sensor shows active throughout full rotation of clutch bell and then when it senses the other magnet it goes out quickly, not sure if this is how it should read (sensor is the Xguard RC one)
3/set proper gear ratio (8.5 to 1 on the N5C)
4/ Flat throttle curves register the proper target RPM I want (1800,1900,2050)
5/ maximum head speed is set at 2400rpm and this is where my problem is.
when I flick out of TH the RPM's shoot to 2400, I have no different head speeds between my normal, idle1, idle2.
Log viewer first showed a noisy sensor so I adjusted filter value to 7 and that seem to fix it because the next log showed governor engaged but still couldn't get rpm to register.
this is getting frustrating due to the fact that I have been working on this for the past month and the same thing happens over and over, start - walk out to flight line- flick out of TH - RPM shoots to MAX. - shut down motor.
I have tried different sensors, switched out throttle servo, double checked my wiring (sensor getting 3.3 volts from the SAT1)
Not sure what to do try next.
software is still at 3.3.1 because my android phone is still at the same version until it gets updated I will not change the unit.
Thanks

Hello,

in the manual for Governor there is stated fwo active magnets are recommended. While active/inactive will rather make a troubles.

Can you change polarity?

Seeing sensor noise might be not an issue.

Please make sure to start governor from idle rpm. So it can spoolup from there.

Firmware can be updated with no problem. Android app will stay at 3.3.1.

Hi Tomas
so just to confirm before I start gluing magnets, I need to orientate two positive side magnets on the clutch bell face up and then set my number of magnets to 2 in the software.
Also, can you recommend start values for the nitro gov.
currently I have these values in my saved profile,
Holding 3
response 2
limit 70% (all my electrics are at 80% but i understand nitro is usually lower value)
Thank you for your assistance on this.
John

Tomas
can you define "active", I have one magnet with North facing up and one magnet with South facing up.
does this mean that I have two "active" magnets? should I set magnet count in software to "2"
Also, when powering the magnet sensor from its cable, I have the + and - connector plugged in to SAT1, and Signal wire in PIT location on Spirit GT, However, not sure if I have polarity correct in the SAT1 location, my volt meter says I do but would like to confirm first.
can you verify the 3 pin polarity on the SAT1 port for the GT unit?
Thanks

setting up a new Tron nitro heli with my GT unit.
Tomas, can you verify my sensor hookup? going to get this together and flying in a day or so.
Thanks in advance.

Hello,

looks good! What sensor it is?

Sensor is XguardRC

Unfortunately we have no experience with the sensor, but the most should work well.

Please note, in our manual we recommend that both magnets have same polarity.
So in the worst case, if it will not read well, you can try to swap it.

In your configuration Sensor Divider should be set to 1. With both facing at the same side there will be 2.

OK
Good info, I haven't glued the magnets in the clutch bell yet, been waiting for your reply.
so I will glue both magnets with the same polarity facing up and set the magnet count to 1 in the software.
most anxious to try this since I had this setup wrong on my Synergy N5C and struggled with getting decent results!
Thanks

If the polarity is same, then sensor divider must be 2. Otherwise RPM would be 2 times higher.

If the measurement is not right, I suspect the sensor require higher voltage for operation. I am not sure what is written in the sensor manual, but it could fix the problem when you will power it from BEC directly. But voltage range of the sensor must be checked first.
