Pre-Flight Preparation and Inspection

Servo and Linkage Inspection

Inspect the servos and linkages for proper opera-
tion.
Before performing this inspection, turn the power
switch for the transmitter to ON and the main switch
for the helicopter to START.
1 Slide Servo and Linkage Inspection
Inspect the servos and linkages to make sure
they smoothly follow the movements of the throt-
tle, elevator, and aileron sticks when the sticks
are moved slowly up-and-down and side-to-side.
Also, make sure the linkages do not wobble.
2 Throttle Inspection
G Throttle fully open and fully closed
• Move the throttle stick to its maximum posi-
tion and check that the throttle valve in the
carburetor moves to the fully open position.
• Move the throttle stick to the slowest posi-
tion and check that the throttle valve in the
carburetor moves to the fully closed posi-
tion. Keep the throttle trim lever in the lowest
position.
G Throttle cable movement and play
• Slowly move the throttle stick up and down
and check that the throttle cable moves
smoothly without catching.
• Check that the throttle cable has a slight
play when the throttle valve is in the fully
closed position.
