Mount the rudder servo and assemble the connectors onto the rudder servo horn as shown. Assemble the front
ends of the pull-pull cables as shown, double looping the wire through the crimp sleeve. Adjust your pull-pull
cables to be snug, with no sag, but not too tight. “Banjo-string-tight” pull-pull cables only sap the power from
your rudder servo and cause poor handling. Just snug is all you need.
Use the X-mount for your motor to mark the firewall for drilling. Drill the 4 mounting holes. The firewall of
the Extra 330 is arranged to allow the widest possible selection of motors to fit. Extra space has been provided
for long motors and long prop adaptors. For this reason, if you motor is compact (like the Torque 4014 or
Reaper GR-45 or 60) you will need to supply spacers to extend the motor forward as shown. Mount your ESC
to the side of the motor-mounting box.
Note: Do not use motors that is over 300g as it will likely to make the plane head heavy.
