12. There are two plywood supports that you need to glue
into the fuselage. The support with two holes gets installed on
the same side of the fuselage as the throttle servo. Glue the
two supports into the slots in the side of the fuselage.
❏
13. Cut one of the 14" [350mm] outer plastic pushrod
tubes to a length of 10" [254mm]. Insert it through the hole
for the throttle, through the fi rewall, into the fuselage and into
the hole in the plywood support as shown in the photograph.
Roughen the tube with sandpaper where the tube contacts
the fi rewall and former. Glue the tube to the fi rewall and the
plywood support.
❏
14. Locate the 36" [914mm] inner pushrod tube and cut a
13" [330mm] piece from it. Screw a 2-56 x 1" [25mm] threaded
wire ¼" [6mm] into the inner pushrod. Screw a nylon ball link
onto the threaded wire. Slide the pushrod tube into the tube
you installed in the fi rewall and snap the ball link onto the ball
you installed on the throttle arm.
❏
15. Position the carb fully open and rotate the throttle servo
arm to the position to open the throttle. Locate another 2-56
x 1" [25mm] threaded wire, 2-56 nut, 2-56 threaded clevis
and silicone clevis retainer. Thread the assembly together.
Place the clevis in the outer hole of the servo arm. Cut the
inner pushrod to the fi nal length required for the threaded
wire to screw into the pushrod. Install the wire, clevis, 2-56 x
1" [25mm] threaded wire, 2-56 nut, 2-56 threaded clevis and
silicone clevis retainer into the pushrod tube. Install the clevis
into the outer hole of a short, 5/8" [16mm] servo arm.
Building Note: You now need to decide if you are going to
use a separate servo to activate the choke. Some modelers
like this method while others prefer a manual choke. Either
is acceptable. As part of your consideration for installing the
