Post subject:  Someone help me?
Hello everyone
I need help, since I changed the radio I went from Dxogen2 to Ix12, I have the internal governor of the Spirit pro that does not work well for me
My Heli is an Oxy3 with Spm4649t and a Hw V4 60 amp
In the radio I use Normal curve 50-80-80-80 -80 idle 1 and 2 both with 90 90 90 90 90 as curves.
I configured the spirit governor max 4,000 rpms and chose as sensing divider 14 because my pinion is 10t and my main gear is 140, then I left everything by default in the spirit governor tab.
I don't use the telemetry UNI cable, but I made the connection of the spm 4649t and the spirit and I can see the rmps and the volts on the radio, but the governor's rmps are not maintained and are often exceeded I also arrive at 4,100 rpms. before enabling the governor in spirit, I calibrated my throttle with linear curve in radio 0 25 50 75 100 and then I enabled the spirit governor.
I can't understand why, am I using option 2 in my esc hw, that is Helicopter linear throttle? Does anyone say that it is better to use Fixed wing.but the spirit manual says that who has the ver 4 of the esc hw must use option2 ( Helicopter linear throttle)
What's wrong? Often the heli rpms are very high and do not go down even if from bank 1 (idle1 flat curve 90 90 90 90 90) I switch to the normal curve 50 80 80 80 80.also in the governor rmps test tab rpmss are really very high.
Thanks

It seems you've mistaken gear ratio and sensing divisor. Sensing divisor is the number of poles in the motor divided by two. Your pinion and main gear ratio is under that in the governor tab.

Make sure you have enable governor checked in the governor tab for all your banks. Start over governor testing with response gain 5 and holding gain 1.

hello I was wrong to write.

the sensing divisor is right in my case is 3 and the gear ratio 14 is all correct in the governor tab, even on the radio, the curves. I don't use the bank on the spirit, but the flight mode on the radio to change normal / idle1- 2. It is the governor who works badly with my esc. There is something wrong somewhere. I did not understand where.You can see my attachment

I have noticed this problem without blades, on the test bench. in practice without the blades my heli does not keep the governor's rpms,
(I think it's fair without load) but and often on the normal curve 50 80 80 80 80, on the lowest value 50 I should have 2,200 rpms , while without blades, but not always and that's what confuses me, sometimes they are at 2,200 exactly, sometimes random at 3,600.
Thanks
