The main purpose of the governor is to keep a constant headspeed, regardless of load. And the headspeed is set by the throttle input from your TX. Headspeed versus throttle input can be seen from the spreadsheet in post #2. A TX throttle setting of 70% will give you a headspeed of 4700rpm, 75% will give 5050rpm, 80% will give 5500rpm etc.
When using the governor you set a flat throttle curve in the IU modes.

So, when the ESC knows which speed to run at (set by the throttle input) it constantly regulates the power to the motor to achieve this headspeed. Regardless whether the power output is 1% or 99%. It measures the deviation from actual speed and requested speed and applies a correction (this is the "reactive" action).
Typically you will select your motor and pinion so that the governor does not have to go to 100% power output, because then it has nothing more to give, and bogging will result.
A high KV motor and a large pinion will increase this headroom. But normally at the cost of lower efficiency (=flight time) and higher battery loading.

There is also a "predictive" mode. If you use the governor "arm" mode, the governor speed target is set during the arming sequence. And when starting the motor, the throttle input is ignored (as long as it is not zero). This way, the main to tail mix that exists in the 3in1 can be exploited (thanks to Roffey for all the details on the mix!).
In the governor "arm" mode the ESC itself runs in "reactive" mode, but the main to tail mix in the 3in1 provides an additional "predictive" input.
In this mode you will need to set a V-curve for IU throttle, and the shape of the curve determines the amount of "predictive" input.

Charges.

Hi there, just to check it out. U seem to have alot of MCPX in ur posession. Do you provide service to other flyers into zenging their mcpx? Just curious.

[xuen7]

yes of course...

upgrading of motor, installation of a 12A esc, flashing of firmware, metal upgrades etc etc

i have stock for all of these and i provide them for anny mcpx flyers..

Just that in view of the arrival of my TDR, i am not advertising as much as before cause i needed more time to learn about the TDR..
