8. Bend the outer elevator pushrod as shown. Cut off the
excess wire. Center both of the elevators, then center the
elevator servo. Secure the two pushrod wires with two 5/32"
[4mm] wheel collars and 6-32 x 1/4" [6mm] socket head cap
screws. Attach the elevator pushrod to the servo arm with a
nylon Faslink using the same technique used on the rudder
and throttle.
❏
9. Measure down 2-1/4" [57mm] from the top of the
fuselage former and make a line on the former. Do this on
both sides of the fuselage. Locate two 1/4" x 1/4" x 6" [6 x 6
x 154mm] hardwood sticks. Securely glue them to the
former aligning the top of the stick with the lines you marked
on the formers.
❏
10. Locate the 1/8" [3mm] plywood receiver/battery tray.
Place it on top of the hardwood sticks you glued in and place
the tray against the fuel tank to keep the fuel tank in
position. Drill a 1/16" [1.6mm] hole through the mounting
holes in the tray and into the hardwood sticks. Insert and
then remove a #2 x 3/8" [9mm] screw into each of the holes.
Then apply a couple of drops of thin CA into the holes to
harden the threads. Once the glue has cured the tray can be
mounted with four #2 x 3/8" [9mm] sheet metal screws and
#2 washers. Do not install the tray at this time.
❏
11. On one side of the tray, place 1/4" [6mm] foam
between the receiver and the tray. On the other side place
1/4" [6mm] foam between the tray and the battery pack. Use
#64 rubber bands to hold the receiver and battery to the tray.
