195. Insert the top of the Formed Tailwheel Wire through the Nylon Tailwheel Bearing and secure in place with the Steering
Arm. File or grind a flat spot on the wire where the set screw will make contact.
196.
The two tailwheel Steering Springs can now be installed, connecting the tailwheel Steering Arm to the Rudder Horn. Use
needle nose pliers to make a loop in one end of the spring to hook into the outermost hole on the back edge of the rudder
horn. With the rudder and tailwheel both in neutral position, apply a small amount of tension to the spring and use the
pliers to make a 90 deg. bend at the outermost hole in the tailwheel steering arm. Insert the wire into the steering arm and
make another 90 deg. bend back toward the center of the spring, forming a loop. Do the same for the other spring. Do not
over stretch the springs when doing this. A little bit of tension is all you need. Turn on your radio system to check the
movement of the rudder and tailwheel. If there is binding, correct it. The springs should center the tailwheel to the rudder
when it is at neutral.
Fuel Tank
A 12 oz. Du-Bro fuel tank (not supplied) is recommended for the Cub. Assemble the fuel tank per the tank manufacturer’s
instructions, with one vent line and one feed line. Attach a length of heat-proof silicone fuel line (not supplied) to the tank
tubes. Label the fuel lines "carb" and "vent", so you can tell them apart after the tank is place. Working through the cabin
door, insert the fuel lines through the firewall as you slide the tank in place. Use scrap balsa or a couple dabs of silicone
caulk to secure the tank to some part of the fuselage structure, so the tank can’t move around in flight.
A REMOTE FUELING VALVE IS HIGHLY RECOMMENDED! With a scale
cowling, it is sometimes difficult to reach the fuel lines for fueling and de-fueling
the airplane at the field. Du-Bro makes a very handy Kwik-Fill Fueling Valve (part
DUB334, for glow fuel only) that solves this problem in the easiest way. We
highly recommend that you purchase a Du-Bro 334 Fueling Valve, or equivalent,
and install it in your Cub.
In this Cub kit we have included a formed Aluminum Fueler Mount (shaped like
an "L") that we use to mount the Du-Bro Fueling Valve to the firewall. It has a 3/8"
dia. hole on one leg and two mounting holes in the other.
Determine a good location for the fueling valve and mark the location of the mounting holes. Drill pilot holes with a 3/64"
bit, and mount the bracket with two #2 x3/8" Sheet Metal Screws. Mount the Du-Bro Fueling Valve in the 3/8" hole and
then, follow the instructions on the Du-Bro package to hook up the fuel lines properly.
Throttle Pushrod
The throttle pushrod supplied in this Cub kit is the "flex-cable" variety, consisting
of a 1/16" od steel cable running inside a nylon tubing sleeve. At each end of the
pushrod cable is an adjustable "pushrod connector".
197.
With the engine and fuel tank in place, slide the .130" od Nylon Tube for the
throttle pushrod sleeve through the hole in the firewall. Route it along the side of
the tank back to the throttle servo. You will need to make and install a support for
the servo end of the sleeve out of scrap balsa or plywood. The support should be
permanently glued to the model structure and it should aim the sleeve right at the
throttle servo control arm. Glue the sleeve, with the end of the sleeve about 1"
short of the servo arm.
198.
At the front, glue the throttle pushrod sleeve to the firewall. Cut the sleeve about 1" short of the carb throttle arm.
199.
Install the pushrod connectors on each end of the pushrod, and adjust the length of the pushrod to get full throttle
movement.
Self-Adhesive Decals
The decals provided in this kit are made of adhesive-backed mylar, they are NOT water activated transfers. These decals
are not diecut and need to be cut from their sheets with a sharp #11 blade or good pair of scissors. Trim as close to the
image as possible.
