FUTABA 7C-2.4GHZ Instruction Manual page 75

GOVERNORS:
What is a governor? A governor is made up of a set of sensors which read the RPM of the helicopter's head, and a control
unit that automatically adjusts the throttle setting to maintain a constant head speed regardless of changes in pitch of blades,
weather conditions, etc. Governors are extremely popular in competition helicopters due to the consistency provided.
How does it help in helicopter setup? The governor eliminates the need to spend large amounts of time setting up throttle
curves, as it automatically adjusts the engine's RPM to maintain the desired head speed.
GOVERNOR: The Governor mixing function is used to adjust the GV-1 (Governor) speed settings (rS1, rS2, rS3) from the transmitter.
(If you are using a different governor, follow the manufacturer's instructions.)
