Radio Installation Precautions - FUTABA 6XA Instruction Manual

While you are installing the battery, receiver, and servos into your model's fuselage, please
pay attention to the following guidelines:
Servo Notes
Mounting
Use the supplied rubber
Be sure not to overtighten the screws. If any portion of the servo case
directly contacts the fuselage or the servo rails, the rubber grommets will not attenuate
vibration, which can cause mechanical wear and servo failure.
Servo Throw
Once you have installed the servos, operate each one over
its full travel and check that the pushrod and output arms do
not bind or collide with each other, even at extreme trim
settings. Check to see that each control linkage does not require undue force to move (if
you hear a servo buzzing when there is no transmitter control motion, most likely there is too
much friction in the control or pushrod). Even though the servo will tolerate loads like this,
they will drain the battery pack much more rapidly.
Switch Harness Installation
When you are ready to install the switch harness, remove the switch cover and use it as a
template to cut screw holes and a rectangular hole slightly larger than the full stroke of the
switch. Choose a switch location on the opposite side of the fuselage from the engine
exhaust, and choose a location where it can't be inadvertently turned on or off during
handling or storage. Install the switch so that it moves without restriction and "snaps" from
ON to OFF and vice versa.
Receiver Notes
Antenna
DO NOT cut or coil the receiver antenna wire. It is normal for the
receiver antenna to be longer than the fuselage.
DO NOT cut it or fold it back on itself – cutting or folding changes
the electrical length of the antenna and may reduce range. Secure the antenna to the top of
