Radio Signal Distance Test; Tail Rotor Drive Belt Inspection - Yamaha RMAX Type II G Unit Operation Manual

Pre-Flight Preparation and Inspection

Radio Signal Distance Test

Conduct a radio signal distance test to inspect that
the system is operating normally.
Before performing this inspection, turn the power
switch for the transmitter to ON and the main switch
for the helicopter to START.
1 Retract the antenna of the transmitter to its
shortest length.
2 Have one person operate the transmitter while
another person checks the helicopter, with an
approximate distance of 50 m between the two.
3 Operate the transmitter and check that the ser-
vos operate accordingly. Make sure the "
light of the check point indicator is not lit.
If the reach of the radio signals is less than 50 m,
cancel the flight and request your dealer for repair.
If the reach of the radio signals is too short,
radio signal interference could render the
helicopter out of control during flight.

Tail Rotor Drive Belt Inspection

Inspect the condition of the tail rotor drive belt and
apply lubricant to the belt.
Before performing this inspection, turn OFF both
the main switch for the helicopter and the power
switch for the transmitter.
1 Inspect for looseness in the tension of the belt.
2 Check that the belt is free of damage, abnormal
wear, and noise during operation.
3 Apply a sufficient amount of the dealer-specified
lubricant to the belt.
If there is a problem with the belt, cancel the flight
and request your dealer for repair.
If there is a problem with the tail rotor belt, it
could adversely affect the actuation of the tail
rotor, which could cause the helicopter to go
out of control.
