Yamaha RMAX Type II G Unit Operation Manual page 76

Flying Procedure
7 After the engine speed has stabilized, turn the
main switch to the FLIGHT position.
G Before turning the main switch to FLIGHT,
check again that the throttle stick on the
transmitter is in its slowest position.
If the throttle stick is raised, the main rotor
or the tail rotor could spin and cause a
serious accident.
G The safety device will trip when the main
switch is in the START position, prevent-
ing the engine speed from increasing
above a predetermined value. If you hear
an abnormal sound from the engine, do
not turn the main switch to the FLIGHT
position. Instead, turn it OFF and check
the areas that are possibly affected.
Leaving the engine idling for more than 1
minute could stain the spark plug, or
decrease the cooling performance of the
engine.
8 While making sure that the throttle stick does not
rise, quickly walk away from the helicopter, to a
minimum distance of 20 m.
Never turn your gaze away from the helicop-
ter when walking away from it.
