NOSE GEAR
97.
a. The nose gear is held in the nylon bearing by the steering arm. Angle the
arm forward so that when the servo pulls it back for a left turn, the arm will
clear the face of the firewall.
b. A flexible steel cable pushrod with nylon outer tubing (not furnished) is
recommended for the hookup of the nose gear, such as the SIGSH559
Flexible Cable Pushrod. Run the nylon outer tubing through the firewall at
the right spot to connect the inner cable to the nylon steering arm. Epoxy
around the tubing at the firewall so that no oil will leak into the fuselage.
Clevises
Clevises supplied in the kit may be
metal or plastic. If the pins fit too tightly
in the nylon horns, open up the hole
with a No. 51 drill.
Servo Hook
-
Ups
Having the proper connector makes servo installation much easier. We show
here a variety of ways to attach push rods to servos.
The Rocket City 07
Pushrod Retainer works
okay for hooking the
wooden push rods to the
servo unless the
movement or pushrod
angle chosen makes it
bump into the center post
of the servo at the
extreme end of the
movement. (This can be fixed by changing the angle
of approach to the servo or using a longer arm to
bring the retainer out farther away from the center
post of the servo.) This retainer is very easy to attach
and detach.
Du Bro Ball Links, which
come in several different
types, threaded, bolt-on,
rivet, etc., gets the push
rod action up above the
control arm so the
pushrod can approach
from a variety of angles
without any chance of
interfering with the servo
center post. It is good for
cable pushrods. A fine
adjustment can be made
by screwing the end in or out.
The SIGSH736 pushrod
connector is handy for
cable end attachment, as
on the nosewheel
steering arm, but can
also be used on servos
as shown. They are
easily adjustable by
loosening the screw and
sliding the cable.
The SIGSH184 or
Goldberg Snap'R Keeper
can be installed on a wire
push rod after it is bent,
due to the design of the
body of the fitting.
