same location when a gas engine is being used.
Connect a 6-inch (150mm) extension to the battery
to connect it to the ignition switch when installed.
 Reposition the batteries as necessary to
achieve the correct Center of Gravity depending
on your engine or motor selection.
7. Slide the 36-inch (914mm) threaded pushrod into the
pushrod tube in the fuselage. Guide the pushrod out the
exit at the rear of the fuselage.
8. Thread an M3 nut on the pushrod. Slide a clevis retainer
(silicone tubing) on a metal clevis, then thread the clevis
on the pushrod. Prepare the rudder servo horn and install
it on the rudder servo. Connect the clevis to the servo
arm.
9. Thread an M3 nut on the pushrod. Slide a clevis retainer
(silicone tubing) on a metal clevis, then thread the clevis
on the pushrod. Connect the clevis to the center hole of
the rudder control horn. With the radio system on and
rudder servo centered, adjust the clevises to center the
rudder. Once centered, slide the retainers over the forks
of the clevises, then tighten the nuts against the clevises.
