2 Hangar 9 Phoenix 7 ARF Assembly Manual2

Intro

Designed by RC icon Don Lowe, the Phoenix 7 is one of
the most potent pattern ships of the 1970s. Seventh in
the Phoenix series, this Don Lowe creation dominated
the pattern circuit in the mid to late 1970s, won the US
Nationals and earned top placements for the US F3A World
Championship team at the 1977 World Championships in
Springfield, Ohio.

We at Hangar 9 are honored to have had the opportunity
to work with Don Lowe to bring an accurate recreation
of one of the most popular and contest-winning pattern
designs of all time. Finished in Mark Radcliff’s famous trim
scheme from the Phoenix 7 that earned him a spot on the
1977 US World Championship team, the Hangar 9 Phoenix
7 is a reminder of the smooth, arrow-like performance of
yesterday’s pattern ships.

Required Tools and Adhesives

Pin vise Pencil
Thin CA Phillips screwdriver: #1
Drill bit: 1/16-inch (1.5mm), 5/64-inch (2mm)

 1. Locate the items necessary to install the aileron

servos. You will also need to have two servos with
associated hardware as well as the wing.

7Hangar 9 Phoenix 7 ARF Assembly Manual

 2. Prepare the aileron servo by installing the rubber

grommets and brass eyelets following the instructions
provided with the servo.

Hint: Prepare all the servos for your model at this time.
Don’t forget to prepare the retract servo as well if you
are installing the optional retracts.

 3. Secure a 6-inch (152mm) servo extension to the

aileron servo lead using string or a commercially available
connector. This will prevent the extension from accidentally
disconnecting inside the wing.

 4. A string has been installed in the wing to pull the

aileron servo extension through the wing. Tie or tape the
string to the end of the extension.

Note: If you are installing retracts, you will need to pull
the retract air line through the wing at this time as well.
Cut a 14-inch (350mm) piece of airline and tape it to
the servo lead so it can be pulled through the wing at
this time. Once through, guide the end of the air line out
through the opening for the landing gear mount.

 5. Use the string to pull the extension through the wing

and out of the hole located in the top center of the wing.

 6. Place the aileron servo in the opening in the wing

with the output of the servo facing the aileron. Use a pencil
to transfer the locations for the four mounting screws onto
the servo mounts in the wing.

 7. Use a pin vise and 1/16-inch (1.5mm) drill bit to

drill the four holes for the servo mounting screws.

 8. Place 2–3 drops of thin CA in each of the holes to

harden the surrounding wood. This creates a hard surface
for the screws and will help in preventing them from
vibrating loose.

8 Hangar 9 Phoenix 7 ARF Assembly Manual

 9. Use the screws provided with the servo and a #1

Phillips screwdriver to secure the aileron servo in the wing.

 10. Remove the standard servo horn from the aileron

servo. Use the radio system to center the aileron servo.
Place a 180-degree servo horn on the servo, making sure
it is parallel to the aileron hinge line. Use a pin vise and
5/64-inch (2mm) drill bit to enlarge the hole in the servo
arm that is 9/16-inch (14mm) from the center of the servo
horn. Make sure to drill the hole on the side toward the wing
tip. Use side cutters to remove the arm from the servo horn
that will not be used to prevent it from interfering with the
operation of the servo. Secure the horn to the aileron servo
using the screw included with the servo and a #1 Phillips
screwdriver.

Note: The servo has an odd number of splines. You
may need to rotate the horn 180-degrees so it aligns
with the hinge line. Try not to use the sub-trim function
when installing the servo horn.

 11 Attach the 3

1

/2-inch (89mm) pushrod wire to the
servo horn using a nylon pushrod keeper. You may need to
use pliers to snap the keeper on the wire. Slide a silicone
clevis keeper on a clevis. Thread the clevis on the pushrod
wire. With the servo centered, connect the clevis to the
center hole of the control horn. Make sure the aileron is
centered when the clevis is connected. Slide the silicone
clevis keeper over the forks of the clevis to keep it from
opening accidentally in flight.

 12. Repeat Steps 3 through 11 to install the remaining

aileron servo.

9Hangar 9 Phoenix 7 ARF Assembly Manual

 2. Place the landing gear block in the wing. Use a

pencil to transfer the locations for the mounting screws onto
the landing gear rails.

Note: The landing gear block and our suggested
retracts use the same mounting location to make the
installation of retracts at a later date easier.

 3. Remove the block from the wing. Use a drill

and 3/32-inch (2.5mm) drill bit to drill the holes for the
mounting screws. Make sure to place the drill bit as far as
possible in the drill chuck to help prevent drilling through
the top of the wing.

 4. Place 2–3 drops of thin CA in each of the holes to

harden the surrounding wood. This will help prevent the
screws from vibrating loose.

 5. Repeat Steps 2 through 4 to prepare the remaining

landing gear mount for the landing gear block.

 6. Use a 3mm x 5mm setscrew to secure the main

landing gear wire in the landing gear block. Make sure to
use threadlock on the setscrew to prevent it from vibrating
loose. Use the included 1.5mm hex wrench to tighten the
setscrew on the flat that has been pre-ground on the landing
gear wire. Assemble both the left and right assemblies at this
time.

 7. Use a flat file to make a 1/4-inch (6mm) wide flat

area on the end of the landing gear wire. Create a second flat
on the wire that is 7/8-inch (22mm) from the end of the wire.

 8. Place a drop of light machine oil on the axle so the

wheel can roll freely.

10 Hangar 9 Phoenix 7 ARF Assembly Manual

 9. Slide one of the 4mm wheel collars onto the wire.

Tighten teh setscrew on the flat made next to the bend in the
wire. Next, slide the wheel into position. The last wheel collar
can now be placed on the landing gear wire. Position the
collar flush with the end of the wire and use a 3mm x 3mm
setscrew to secure the outer wheel collar. Check that the
wheel can rotate freely. If not, reposition the collars until the
wheel rolls with little resistance. Make sure to use threadlock
on the setscrew to prevent it from vibrating loose.

 10. Repeat Steps 7 through 9 to assemble the remaining

main landing gear.

 11. There is a right and left main landing gear. Place the

gear in the wing and check that the coil faces the trailing
edge of the wing and that the wheel faces to the center of the
wing. Use four #6 x 3/4-inch sheet metal screws to attach
landing gear in the wing. Install the left and right main gear
at this time.

 2. Use a hobby knife and #11 blade to remove the

covering on the top and bottom of the wing for the nose gear
retract.

 3. Use a hobby knife and #11 blade to cut the covering

down the center at the leading edge of the wing. Carefully
peel the covering away to expose the cover plate at the
leading edge of the wing.

 4. Use a hobby knife and #11 blade or razor saw to trim

the plate to the edges of the notch in the leading edge. Use
medium grit sandpaper to smooth the edges where the plate
was cut.

 5. Use a covering iron or trim seal tool to iron the

covering into the notch to finish the opening for the nose
wheel in the leading edge of the wing.

 6. Use a hobby knife with a #11 blade to remove the

covering from the wheel well. Use a covering iron to seal the
edges down in the wheel well and leading edge of the wing.

 7. Place the retract mechanism in the wing. Use a

pencil to transfer the locations for the mounting screws onto
the landing gear rails.

12 Hangar 9 Phoenix 7 ARF Assembly Manual

 8. Remove the retract from the wing. Use a drill

and 3/32-inch (2.5mm) drill bit to drill the holes for the
mounting screws. Make sure to place the drill bit as far as
possible in the drill chuck to help prevent drilling through
the top of the wing.

 9. Place 2–3 drops of thin CA in each of the holes to

harden the surrounding wood. This will help prevent the
screws from vibrating loose.

 10. Repeat Steps 6 through 9 to prepare the remaining

landing gear mount for the landing gear block.

 11. Connect the two air lines to a T-fitting. Cut a short

2-inch (52mm) section of air line to attach to the T-fitting.
Attach a quick disconnect to the opposite end of the short
2-inch (52mm) piece of air line.

 12. Use a drill and 3/16-inch (5mm) drill bit to enlarge

the hole in the wheel.

Hint: Using a drill press for drilling these holes is
recommended so they are drilled straight through the
wheel.

 13. Slide the axle through the wheel. Slide two nylon

washers on the axle, then slide the axle into the adapter. Use
a felt-tipped pen to mark the axle where it will be cut.

 14. Use a rotary tool and cut-off wheel to cut the axle

at the mark made in the previous step. Use a flat file to make
a flat area on the first 1/4-inch (6mm) of the axle for the
setscrew to tighten onto.

13Hangar 9 Phoenix 7 ARF Assembly Manual

 15. Place a drop of light machine oil on the axle.

Assemble the wheel and axle as described in Step 18. Use a
setscrew to secure the axle to the mount. Make sure to use
threadlock on the setscrew to prevent it from vibrating loose.

 16. Repeat Steps 12 through 15 to prepare the remaining

wheel assembly.

 17. Slide the strut into the retract mechanism. Note

the position of the strut in relationship to the retract
mechanism. The wire below the coil will be toward the air
cylinder and the coild facing as shown in the photo. The
coild will be perpendicular to the air cylinder. Use a 5/64­inch hex wrench to tighten the setscrews so they leave a
mark on the retract strut.

 18. Remove the strut from the retract mechanism. Use

a flat file to file a flat on the strut for the setscrews. Place the
strut back in the retract and tighten the setscrews.

 19. Measure 4

5

/8-inch (117mm) from the edge of the
trunion block as shown. Use a rotary tool and cutoff wheel to
trim the length of the strut.

 20. Repeat Steps 17 though 19 to prepare the opposite

retract mechanism and strut. Again, note the position of
the strut in relationship to the retract mechanism. We have
shown the retracts with the struts next to each other so they
can be easily compared for positioning.

14 Hangar 9 Phoenix 7 ARF Assembly Manual

 21. Pull the previously installed air line out of the wing

near the retract opening and connect the airline to the retract
air cylinder fitting on the retract.

 22. Mount the retract in the wing using four #6 x

3/4-inch sheet metal screws. Make sure to route the airline
back into the wing from where it connects to the retract air
cylinder. Make sure the loop is not too tight, as it could kink
and damage the airline.

 23. Slide the wheel assembly on the strut. Check

that the wheel is pointing straight ahead and parallel to the
fuselage centerline. Tighten the setscrews on the axle mount
to leave marks on the wire strut.

 27. File a flat on the wire strut for the setscrews on the

axle mount to secure to.

 28. Place the wheel assembly back on the strut.

The distance between the wing and center of teh axle will
measure 53/16-inch (132mm). Tighten the setscrews to
secure the wheel and axle to the strut. Make sure to use
threadlock on the setscrews to prevent them from vibrating
loose.

 29. Repeat Steps 16 through 28 for the remaining retract

strut and wheel.

Stabilizer Installation

Required Parts

Fuselage Carbon stabilizer tube
Stabilizer assembly (right and left)

Required Tools and Adhesives

Medium grit sandpaper 30-minute epoxy
Mixing cup Mixing stick
Epoxy brush Paper towel
Rubbing alcohol Low-tack tape

 1. Locate the left and right stabilizer halves and carbon

stabilizer tube. You will also need to have the fuselage for the
stabilizer installation.

 2. Use low-tack tape to outline inside the raised area

1/8-inch (3mm) on the fuselage where the stabilizer will rest.
This will help prevent accidentally sanding the fuselage.

 3. Use sandpaper to scuff the area of the fuselage

for the stabilizer. You don’t need to sand through to the
fiberglass: only enough to roughen the surface for the epoxy
to adhere to.

 4. Remove the tape and use a paper towel and rubbing

alcohol to remove any dust or debris from the area sanded.

 5. Repeat Steps 2 through 4 to prepare the opposite side

of the fuselage.

 6. Use sandpaper to lightly sand the outside of the carbon

stabilizer tube. Use a paper towel and rubbing alcohol to
remove any oils, dust or debris from the outside of the tube.

 7. Slide the tube into one of the stabilizer halves. The

tube will slide easily into the stabilizer, so don’t force it
farther than it will easily slide.

 8. Slide the tube and stabilizer into the hole in the

fuselage. The stabilizer will fit tightly against the fuselage.
