Main Rotor RPM adjustment
The Galaxy autopilot and motor control system is featuring an intuitive adjustment process.
There are many situations where the main rotor RPM (head speed) would be adjusted, the
Galaxy is tested and shipped with a setup rotor RPM but environmental and payload factors
may result in the default RPM not being suitable. A standard rule that applies is higher the
payload then higher the rotor RPM.
*Adjusting the RPM value has an effect on the gains settings and caution must be used when changing the
RPM values and flight testing, only change from default under the guidance of your distributor and/or the
manufacturer (Innoflight International pty ltd).

Adjusting the RPM
Connect to the Galaxy USB-C port and open the autopilot interface. After the Galaxy has
established a connection to the interface, navigate to the "XIV. Peripheral" page. The Motor
Idle PWM value is what dictates the rotor speed, raising this value will increase the main
rotor RPM. Adjustments of increments no more than "15" per adjustment is recommended.
