1.1 Throttle

For usage of the Spirit Governor it is necessary to connect the Throttle (ESC or the Throttle servo) to the following port:

Spirit and μSpirit - AUX port
Spirit Pro, Spirit 2 and Spirit GT - AUX1 port
Spirit RS, Spirit GTR and Spirit W1 - THR port

1.2 RPM signal

To make the governor work well it is very important to choose an appropriate RPM sensor. RPM sensor can be external or built-in in the ESC.

Cable that carry RPM signal must be always connected when Governor is used.

Connect RPM signal cable to the pin of the unit:

μSpirit - P pin - upper pin of the P/E/A port
Spirit - PIT pin - pin in the middle of ELE/PIT/AIL port
Spirit Pro, Spirit 2 and Spirit GT - PIT pin - pin in the middle of ELE/PIT/AIL port
Spirit RS and Spirit GTR - RPM pin - pin in the middle of EXT/RPM/E2 port
Spirit W1 - RPM pin - pin in the middle of T2/RPM/X port

Sensor can be powered from any available Satellite port (SAT) or directly from a BEC. Satellite port is giving 3.3V, while BEC is operating usually at 5 - 8V.

I thought I read somewhere to plug the ESC into Aux1 but I've read so much it's hard to remember.
