PRECAUTIONS
• Connect the receiver, servos, switches, and battery firmly as
shown in Fig. 9. Then extend the transmitter and receiver
antennas fully.
• Set the transmitter power switch to ON. Then set the receiv-
er power switch to ON. The servos stop near the neutral
position. Operate the transmitter sticks and check that each
servo follows the movement of the stick.
•Connect the pushrod to each servo horn, then check if the
direction of travel of each servo matches the direction of
operation of its transmitter stick. To reverse the direction
of servo travel, switch the servo reversing switch.
• Operate each servo over its full stroke, and check if the push-
rod binds or is too loose. Applying unreasonable force to the
servo horn will adversely affect the servo and quickly drain
the battery. Always make the travel of each control mecha-
nism somewhat larger than the full travel (including trim) of
the servo horn. Adjust the servo horns so that they move
smoothly even when the trim lever and stick are operated
simultaneously in the same direction.
• Be alert for noise.
This set is noise-resistant, but is not completely immune to
noise. We recommend the use of noiseless parts.
•When installing the switch harness, cut a rectangular hole
somewhat larger than the full stroke of the switch and install
the switch so that it moves smoothly from ON to OFF. This
also applies to the switch mount when the switch is installed
inside the fuselage and is turned on and off from the outside
with a piece of wire, etc. Install the switch where it will not
be exposed to engine oil, dust, etc.
