Using the Manual
This manual is divided into sections to help make
assembly easier to understand, and to provide breaks
between each major section. In addition, check boxes
have been placed next to each step to keep track of
completed sections. Steps with a single box ( ) are
performed once, steps with two boxes ( ) indicate
that the step needs to be repeated, such as for left
and right wing panel, or two servos etc.
Before beginning it is a good idea to read through the
manual completely to familiarize yourself with the
assembly process. Remember to take your time and
follow the directions.

Before Starting Assembly
Before beginning the assembly of your model, remove
each part from its bag for inspection. Closely inspect
the fuselage, wing panels and tail section for
condition. If you find any damaged or missing parts
contact the place of purchase.
Any wrinkles in the covering can be removed with a
heat gun or covering iron. Use caution while working
around edges and areas where colors overlap to
prevent separating the covering.

Workspace Preparation
During the course of building your Taylorcraft we
suggest that you use a soft base on the building
surface. Such things as a foam stand, large piece of
bedding foam or a thick bath towel will work well and
help protect the model from damage during assembly.
A flat area measuring at least 24 x 72-inches is
required to work on the model sub-assemblies
comfortably. The completed and assembled model
requires a space of 72 x 90-inches. Ensure you have
adequate lighting, and a place to set aside parts that
have been completed.

Optional Accessory
Setting up servos is a whole lot easier with a JR®
MatchMaker™. It lets you accurately center servos,
evaluate endpoints, and cycle servos at varying
speeds, without ever having to switch on a transmitter.
It allows the precise digital centering of up to 2 servos
at a time to help with setup on the building bench.
Work Area Cleanliness
It is a good practice to maintain a clean work area,
both to prevent damage to your model and to keep
track of parts and hardware. Put away any tools not
being used, and set aside parts of the model that are
not being worked on.
Of special importance is keeping debris out of
sensitive components such as the radio and engine or
motor. Tape over engine intake and exhaust ports
when drilling or cutting the firewall and cowling to
prevent causing damage to the internal components.
Hardware Practices
When installing hardware that consists of a button
head machine screw, washer and nut, use an openended or box wrench to tighten the nut while holding
the fastener with a hex wrench. The washer provides
a bearing surface for the nut while it is being turned,
holding the screw with a wrench prevents damage to
the part, particularly on painted components.

Step 18
Install the spinner and propeller with the appropriately
sized wrench for the engine being used.
Center of Gravity
An important part of preparing the aircraft for flight
is properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for
your model is 3 3/4-inch (95mm) behind the leading
edge of the wing (25% chord). Mark the location for
the Center of Gravity on a piece of low-tack tape on
the bottom of the wing next to the fuselage as shown.
When balancing your model, support the plane
upright at the marks made on the bottom of the wing
with your fingers or a commercially available
balancing stand. This is the correct balance point for
your model. You might find you need to add a small
amount of weight to either the front or back of the
fuselage to achieve the correct balance.
Step 17
Secure the cowl with four 4-40 x 1/2-inch button head
machine screws using a 5/64-inch hex wrench.
After the first flights, the CG position may be adjusted
to suit your personal preference. Prototypes have been
flown with the CG as far back as 4 1/8-inch (105mm).

Control Throws
Step 1
Turn on the transmitter and receiver of your model.
Check the movement of the rudder using the
transmitter. When the stick is moved right, the rudder
should also move right. Reverse the direction of the
servo at the transmitter if necessary.
Step 2
Check the movement of the elevator with the radio
system. Moving the elevator stick toward the bottom
of the transmitter will make the airplane elevator move
up.
Step 3
Check the movement of the ailerons with the radio
system. Moving the aileron stick right will make the
right aileron move up and the left aileron move down.
Step 4
Use a ruler to adjust the throw of the elevator, ailerons
and rudder.

not listed and should be adjusted according to
each individual model and preference.
Hangar 9 Taylorcraft 20cc Assembly Manual
Flight Preparations
Flight preparations should be performed each time
you travel to the flying field. Because your model will
encounter a variety of situations, it is best to keep an
eye on the various components of your model to keep
it in the best flying condition.
Checking the Frequency
When using a Spektrum radio system, follow the
guidelines for use of DSM radio systems at your
particular field.
Checking the Controls
Before starting your engine, check to make sure the
controls are operating in the correct directions and the
linkages and surfaces are not binding anywhere. Also
look at the clevises and clevis retainers to make sure
they are secure and will not come loose or fail in flight.
Fueling your Model
Fill the fuel tank with the proper fuel. Fill the tank by
connecting the fuel pump to the line going to the
needle valve or to the fuel dot on the side of the
cowling. Disconnect the fuel line attached to the
pressure fitting of the muffler; your tank is full when
fuel begins to run out of the pressure or vent line.
Reconnect the fuel lines to the needle valve assembly
or insert the plug into the fuel dot and connect the line
to the muffler.
Note: It is very important to reconnect the lines to
the correct place. If they are reconnected
incorrectly, the engine will not run properly.
49
Maintaining Your Model
The following is a check list you should follow
every time you have completed a flying session with
your model. Doing so will keep your aircraft in the best
flying condition.
Clean Up
After a long flying session with your model, you will want
to clean it before loading it into your vehicle to head
home. Use a cleaner and a paper towel to wipe down
the exterior of your plane, removing the fuel residue.
Remember, a clean airplane will last longer since the
fuel won’t be able to soak into any exposed wood.
Checking the Propeller
Check to make sure the propeller is tightly secured to
the engine. If not, remove the spinner and use a
wrench to tighten it. If you have had any not so great
landings, you will want to inspect the propeller for any
damage. Small nicks and scratches can quickly
become fractures, causing the propeller to be unsafe
for flight. Always carry a few spare propellers so a
damaged propeller can be replaced at the field,
increasing your flying time per trip to the field.
50
Checking the Clevises
Inspect the aileron, elevator and rudder clevises to
make sure they are connected and in good working
order. If you find a clevis that is showing signs of wear
or is broken, replace it with a new clevis. Also check
the nylon connectors at the servo for any wear or
damage. If they look worn or in bad shape, replace
them as well.
Checking the Control Horns
Inspect the control horns to make sure they have not
crushed the wood of the control surface. If so, remove
the control horn screws to remove the control horn.
Place 2–3 drops of thin CA into each of the screw
holes. In addition, use a T-pin to poke small holes in
the covering in the area where the control horn
mounts, then saturate the area with thin CA. This will
harden the wood and give the control horns a solid
surface to be mounted to.
Check the Muffler Bolts
Use the appropriate hex wrench to make sure the
hardware holding the muffler onto the engine is tight
and has not vibrated loose during flight.
Check the Engine Mount Bolts
Remove the spinner (if used) and propeller from the
engine. Remove the cowling , and if necessary
remove the muffler to gain access to the engine
mounting bolts. Use a Phillips screwdriver or hex
wrench to make sure the four bolts securing the
engine to the mount or firewall are tight.
Checking the Wheel Collars
Check the setscrews on the wheel collars for the main
and tail wheel to make sure they are not loose. Use a
hex wrench to tighten the setscrews. It is suggested if
they loosen frequently to remove them, reapply
threadlock to the setscrews, then secure the wheel
collars back into position.

Safety Do’s and Don’ts for Pilots
● Ensure that your batteries have been properly
charged prior to your initial flight.
● Keep track of the time the system is turned on so
you will know how long you can safely operate your
system.
● Perform a ground range check prior to the initial
flight of the day. See the “Daily Flight Checks
Section” for information.
● Check all control surfaces prior to each takeoff.
● Do not fly your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
● Do not fly during adverse weather conditions. Poor
visibility can cause disorientation and loss of control
of your aircraft. Strong winds can cause similar
problems.
● Do not point the transmitter antenna directly toward
the model. The radiation pattern from the tip of the
antenna is inherently low.
● Do not take chances. If at any time during flight
you observe any erratic or abnormal operation, land
immediately and do not resume flight until the
cause of the problem has been ascertained and
corrected. Safety can never be taken lightly.
Hangar 9 Taylorcraft 20cc Assembly Manual
Dual Rate Recommendations
● We recommend that the rudder dual rate be set to
Low for takeoff to help minimize overcorrection
during the takeoff roll.
● We recommend the rudder dual rate be set to High
for landing to help maintain heading as the model
transitions from flying speed to taxi speeds.
● Elevator and Aileron dual rates should be adjusted
for personal feel and also if there are any unusual
wind conditions.
Age Requirements
Age Recommendation: 14 years or over. This is not a
toy. This product is not intended for use by children
without direct adult supervision.
Daily Flight Checks
Step 1
Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 9.5V on the
transmitter if you are using a JR or Spektrum transmitter
that uses 8-cells to power the transmitter. Do not fly if the
receiver pack is at or below 4.7V. To do so can crash your
aircraft.
Note: When you check these batteries, ensure that
you have the polarity correct on your expanded scale
voltmeter.
Step 2
Check all hardware (linkages, screws, nuts, and bolts)
prior to each days flight. Be sure that binding does not
occur and that all parts are properly secured.
Step 3
Ensure that all surfaces are moving in the proper manner.
Step 4
Perform a ground range check before each flying session.
Step 5
Prior to starting your aircraft, turn off your transmitter, then
turn it back on. Do this each time you start your aircraft. If
any critical switches are on without your knowledge, the
transmitter alarm will warn you at this time.
Step 6
Check that all trim levers are in the proper location.
Step 7
All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch moves
freely in both directions.
