Hi.

Is there a way of setting governor RPM lower than 1500. I have several large scale helis that require 1000 to 1400 RPM head speed.
I have used several Spirit gyros in large scale models with great success and I would like to use the governor function.
Regards.
Roger

Halve the sensing divider and double the max headspeed. Or double the gear ratio and double the headspeed

(do you also wonder why they do not want to fix those minimum and maximum values and they suggest these crazy workarounds?)

Yeah not sure why really.... Maybe some number / code limitation but still

OK I'll give that a try. I guess the command and the measured values will be (2) twice the real RPM.

Yeap correct

Hi,

if you need 1000 - 1400 RPM, you can set 1500 as Max Head Speed without any problem.
To achieve 1400 RPM, just set 93,5% TC. To achieve 1000 RPM it should be 67%.

Nothing else needed to change, so all can be configured properly.

Slightly off but what is the formula to calulate headspeed % for instance with 3200 max?

Formula is quite simple: Requested RPM = Max Head Speed * Throttle Curve


Throttle Curve is usually in % so you have to divide value by 100.
