30 Minute Z-poxy
Wire cutters
Pliers
Drill with bits: 1/32”, 1/16”, 1/8”, 5/32”, ¼”
See the list at the end of the instruction book for a
list of additional R/C equipment you will need to
complete the 1.20 Edge 540.
1.
Locate (8) hinges.
2. Use the picture as a guide to find the (4) holes in
each aileron and each side of the wing. Test fit a
hinge in each hole.
3. Put a small drop of oil on each hinge, then use 30
minute epoxy on each hinge and hole. Press the
ailerons in place, leaving a 1/32” gap at the hinge
line, then wipe off any excess epoxy off with
alcohol and a paper towel.
4. At the two locations on the wing, remove the
covering from the hole to install your aileron
servo. Check the hole for the servo wires. If
needed, use a piece of 3/8 or ½” brass tube to cut
a passage for the wire to the servo opening.
5. Install your aileron servo with the hardware
included with your radio. You may need to
enlarge the hole in the wing with a file or small
saw, depending on the size of the servo you use.
Drill a small pilot hole (1/32”) for each screw.
Hook the servo to your radio and turn it on. Set
the trim tabs to neutral and center the servo.
6. Locate the (2) 8” long 2-56 rods, (2) clevis, (2)
couplers, (2) washers, and (2) 3 x 40mm Philips
screws. Install a clevis on the end of each rod.
7. Install a (4) arm servo wheel on the servo
temporarily, making sure it is parallel to the
wing. Locate the hard points in the ailerons, and
pierce the covering with a sharp hobby blade.
Install the (2) aileron control horn screws from
the top of the wing, down through the aileron.
Secure the bolt with a washer, nut, and thread
lock. Install the (2) couplers on the control horn
bolts until the threads just show from the tops.
Hook the links to the aileron couplers and lay the
rods across the servo arm.
8. Mark the location of the servo arm holes on the
control rods. This is the location for the “z”
bend on the each control rod. Make a “z” bend
on each control rod with needle nose pliers or
“z” bend pliers, then cut off the excess control
rod. Install the “z” bend on the servo arm, at the
same hole on each arm. You may need to
enlarge the hole with a small drill bit. Cut off
the (3) extra arms with wire cutters.
9. Check again that the servo is centered with your
radio, then reinstall the servo horn and screw it
in place. If the ailerons are not level, disconnect
the links and adjust them until they are level.
Place a short piece of fuel tubing around each

clevis to secure in place.
10. Using a sharp hobby blade, cut the covering
away from the wing tube and locating pin holes.
You may want to seal the covering down with
CA or a sealing iron.
11. Test fit the wing tube through the fuselage. Use
a ruler to help center the tube in the fuse, then
mark the alignment with a permanent marker.
12. Temporarily mount the wing on the wing tube,
sliding the dowels in the locator holes. Be
careful to keep the tube centered in the fuse.
13. Locate the (2) 4-40 x 1” bolts. With the wings
tight against the fuse, Drill (2) 0.1” holes through
the aluminum tube.
14. Use a 4-40 tap to thread the holes in the tube.
15. Counter sink the hard points 1/8” deep with a
1/4”drill bit. Work carefully to keep the wood
from splitting.
16. Test fit the bolts in the holes. Put thread lock on
one bolt and cover the bolt hole with 3m vinyl
tape. Leave this bolt in place permanently.
17. When ready for flying, put 3m clear vinyl tape
over the other bolt.
18. Cut the covering from the holes in the rear of the
fuse for the horizontal stabilizer. Temporarily
install the horizontal stabilizer using the stab

tube to hold it in place. Center it as was done
with the wing tube.
19. Locate the hole in the mounting block of the stab
and pierce the covering with a sharp hobby
blade. Check the fit of the locating pins in the
fuse holes. If needed, run a bead of ca around
the pins and spray with kicker, then sand the glue
down to fit in the holes with a tight fit.
20. Locate the (2) 4-40 x 5/8” bolts with the
stabilizer halves tight against the fuse. Drill (2)
0.1” holes through the aluminum tube.
21. Use a 4-40 tap to thread the holes in the tube,
then install the screws.
22. Locate the tail surface hinges. Notice that there
are two hinges that are cut down. These must go
on the inside positions of the elevator halves to
clear the stab tube.
23. Locate the (3) hinge holes in each of the elevator
halves, rudder, and corresponding holes on the
stabilizers, then open the covering with a sharp
hobby blade. Test fit one of the (9) hinges in
each of the holes. Put a small drop of oil on each
of the hinges. Install the hinges in the control
surfaces only, using 30 minute epoxy, then align
them by pressing onto a flat surface. Clean up
any excess glue with alcohol. Continue on to
the next step before the glue sets up.
24. Install the surfaces on the rear of the fuselage
using 30 minute epoxy. Press in place and leave
a 1/32” gap. Wipe off any excess glue with
alcohol and a paper towel. Let set until cured.
25. Install your servos in the servo tray in the
fuselage. Depending on what servos you use,
you may need to widen the servo openings. Drill
a small pilot hole (1/32”) for each servo screw,
then install. Connect the servos to your radio
and center trim tabs and controls. Temporarily

press a straight servo horn in each servo.
26. Locate the hard points for the control horn
screws in the elevator halves and pierce the
covering with a sharp hobby blade.
27. Install the (2) 3 x 35mm screw from the top of
the surface and fasten with a washer, nut, and
thread lock. Screw a coupler on the end of the
screws until the first thread is exposed. (the
elevator servo will be installed later after the
motor is mounted)
28. Locate the tail hardware, (1) threaded rod, (2)
couplers, (2) nuts, (2) washers.
29. Locate the rudder hard point and pierce the hole
on both sides with a sharp hobby blade. Put the
threaded rod through the hole and capture in
place with a washer, nut, and thread lock on each
side. Use your ruler to make sure the sides are of
equal length.
30. Install the rudder couplers on each side of the
threaded rod until the first thread is exposed and
the coupler points toward the front of the fuse.
31. Locate a (4) arm servo horn and remove 2 arms
as shown above. Cut the cable for the rudder
control in two equal lengths, approximately 36”.
Slide a crimp fastener on each cable, then loop
the cable through the outside holes of the servo
horn. Slide the fastener back over the loose
cable end and pull up the slack as shown above.
Crimp the fastener several times using some
pliers. Pull the cable firmly to test.
32. Install a clevis on the end of each of the two
rudder connectors, then snap in place on the
rudder couplers. Cut the covering from the slots
in the side of the fuse for the cable exit.
33. Use your radio and center the trim on the rudder
servo. Install the servo horn on the rudder servo
with the arms perpendicular to the fuse sides.
Use a long piece of wire or yellow Sullivan
nyrod to help feed the wire through the holes to
the rear of the fuselage. Be sure to keep the
cables from twisting.

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
34. Slide the clear tubing over the cables and half
way into the holes in the fuse. Glue in place
with ca.
35. Slide two more cable fasteners down the cable,
then insert the cable through the holes at the end
of the rudder clevis.
Loop the cable back and slide the cable fastener
over the loose end of the cable. Pull the loops as
tight as possible, and then crimp the fasteners.
There should be only slight tension on the cables
to the rudder, and it should be centered. This can
be adjusted by loosening or tightening the clevis
on the cable connectors.
36. Locate the tail wheel bracket and parts.
37. Fasten the tail bracket at the rear of the fuse with
two ½ screws. Drill two 1/16 pilot holes before
installing. Install so the angle is aligned with the
edge of the vertical stabilizer.
.
38. Locate the springs for the tail, and prepare the
ends by bending a loop on each end.
39. Drill a 1/16” hole in the rudder, just past the
clevis.
40. Install a spring on each side of the rudder.
Shorten the springs if needed to put even tension
on the arms and keep the axle centered.
41. Install the tail wheel on the axle, then secure
with the small wheel collar and set screw. Use
some thread lock on the screw.
42. Place the fiberglass cowl on the fuse and fasten
with the ½” #4 screws through the holes.
Measure from the engine crank hole to the
firewall surface with a ruler. Write down the
length. This is the distance that will be from the
firewall to the prop back plate on your motor.
43. Place your engine in your engine mount and bolt
in place with (4) 8-32 x 1” bolts (Dubro #318).
Either tap the holes into the engine mount, or
drill through and lock in place with 8-32 washers
(Dubro #327) and lock nuts (Dubro #329). Try
to position the motor on the motor mount so that
© 2001 Lanier R/C Page - 6

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
the distance from the back of the motor mount to
the front of the prop plate is the same as the cowl
measurement you made earlier.
44. Use a ruler and measure up from the bottom of
the firewall 3-1/2”. Mark a horizontal line
across the firewall at that point.
45. Use your ruler again to find the center of the line
and mark it. Make a second mark 1/8” to the
right of the center mark, and make a second
mark, then draw a line perpendicular to the first
line.
46. Center your engine mount on these lines, then
mark the holes on the firewall.
47. Drill the holes for 8-32 bolts and temporarily
mount the engine on the firewall with 8-32 x 1”
bolts (Dubro #318), washers (Dubro #327), and
blind nuts (Dubro #347).
48. Measure the distance from the firewall to the
front of the prop back plate and compare to the
measurement you calculated earlier. You should
have a minimum of 1/8” clearance from the back
of the prop to the front of the cowling. If
needed, use some scrap plywood spacers to
space the engine forward.
49. Place two #8 washers between the firewall and
engine mount on both right side engine mounting
bolts (facing the firewall) to give the engine right
thrust.

50. Mark on the firewall the location where the
throttle control rod should pass through.
Remove the engine and drill the marked hole
with a 1/8”drill bit. Using the throttle servo as a

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
guide, drill the second bulkhead for the control
rod.
51. Slide the “z” bend of the engine control rod into
the hole on the servo arm of your throttle servo.
Temporarily install your engine using the engine
bolts, washers, and nuts, sliding both halves of
the engine control rod through the small hole in
the firewall.
52. Make sure your carburetor and throttle servo are
at low position. Reverse your servo if necessary.
Install an EZ connector (Dubro #121, NOT
INCLUDED) in the hole approximately the same
length of the servo arm. Trim the throttle control
rod to approximate length, then insert through
the hole in the EZ connector. Tighten the
connector enough to test the throw of the servo
and adjust as needed to allow for maximum
throw, but not bind the servo. When satisfied,
trim the control rod to ¼” past the EZ connector.
Install the servo horn screw, but don’t fasten the
EZ connector yet, you may need to pull the
engine out again soon. When everything is fit,
then fuel proof the firewall with polyurethane or
thinned epoxy.
53. Test fit the cowl over the engine to see what
needs to be relieved.
54. Tape a strip of heavy paper on the side of the
fuse as shown. Mark the areas that need to be
cut, then cut out the holes on the paper.
55. Reposition the paper back on the fuse and secure
in place. Do the same for the needle valve on the
top of the fuse.
56. Place the cowl on the front of the fuselage and
secure in place with the screws. Mark all the
holes with a pencil or water soluble marker.
57. Remove the cowl and drill all needed holes. You
may need to use a rotary tool and sanding drum
or a small fine blade saw and sand paper to open
the hole for the engine head.
58. Reinstall your engine and test fit the cowl. Use
the #4 screws and washers to secure the cowl.
Adjust the openings if needed.
59. Install your muffler on the engine and test fit the
cowl again. A “Pitts” style muffler should not
require much adjustment, but a standard aircraft
muffler will require additional openings.
60. Now is when to install the tail servos.
Depending on the engine and mount used, you
may want to install the elevator servo up in the
fuse servo tray. Both installations are shown, but
the materials for the push rod is not included.
Use of a light engine my require you to put all
the radio gear and even some lead in the nose to

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
achieve proper balance. For the front servo
installation, skip to step 64, for the rear servo
installation, continue to next step.
61. Locate the holes in the side of the fuse for the tail
servos. There is one on each side. Note that the
cutouts are not opposite each other, but are
offset. This allows you to mount one servo with
the arm down and the other with the arm up,
eliminating the need for a servo reverser and
allowing you to use a standard “Y” harness. Cut
the covering from the slots with a sharp hobby
knife.
62. Locate the two push rods, (2) 8” 2-56 rods.
Install a clevis on the end of each 2-56 rod, then
install a 4 arm servo horn on each servo, making
sure the arms are square to the tail surfaces.
63. Plug a clevis into each coupler and rod, then lay
them across the servo arm. Mark the location of
the servo arm holes on the control rods. This is
the location for the “z” bend on the each control
rod. Make a “z” bend on each control rod with
needle nose pliers or “z” bend pliers, then cut off
the excess control rod. Install the “z” bend on
the servo arm, at the same hole on each arm.
You may need to enlarge the hole with a small
drill bit. Cut off the (3) extra arms with wire
cutters. Skip to step 77.
64. Front servo installation. Note: For 3d
aerobatics or when using a high-end motor,
use the rear servo method and use 4-40
pushrods, even if nose weight is needed for
proper balancing. You will need the following
materials, a 24” x 3/8 Dia. Hardwood dowel
(NI), (2) 2-56 x 12” control rod (dubro #172), (2)
2-56 clevis (Dubro#122), and (2) pieces of 3/8
shrink tube (Dubro #440) or thread and CA to
fasten the ends of the control rod.
65. Twist the 2-56 clevis on the end of each push
rod, then measure back 6”. Make a bend of
about 5 degrees at that distance.
66. Measure 1-1/4” in on each end of the pushrod.
67. Use a sharp hobby blade to cut one groove on the
servo end, and two groves on the elevator end of
the push rod. Make sure the servo end is
centered from the two grove end.
68. Drill a 3/32” hole at the back of the groove,
through the pushrod. Make a second hole on the
two groove end, about 1/8 forward of the first.
69. If you are using shrink tubing, slide it on the
pushrod now. If you are using thread and ca,
continue on.
70. Align the control rods on the elevator end of the
pushrod, keeping the clevis even with each other.
Mark the control rods where they intersect with
© 2001 Lanier R/C Page - 9

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
the holes, then bend them 90 degrees. Cut the
control rods off about ¼” from the bend.
71. Insert the control rods in the elevator end of the
rod and slide the shrink tubing over the joint, or
wrap with thread and glue with ca.
72. Measure down from the horizontal stabilizer ¾”,
and follow the ends of the rudder cable exits up
to mark the opening for the push rod exit. Cut
the opening with a sharp hobby blade.
73. Slide the control rod down the fuse center and
feed the clevis out the openings to the elevator.
Snap the clevis on the control coupler.
74. Use on of the 2-56 control rods and bend one end
down ¼”. Slide the other piece of shrink tubing
down the pushrod if needed.
75. Insert the control rod in the pushrod, and lay
over the elevator servo. Mark the intersection
and make a “z” bend for the servo horn, then
install and test.
76. Slide the heat shrink tubing in place and heat, or
install the thread and ca. Adjust the clevis to
make sure the elevator halves are level to each
other.
77. Center the gear on the landing gear plate and
mark the holes with a marker.
78. Drill through the landing gear plate with a 5/32”
bit and then install (2) 4 x 20mm screws and
washers.
79. Fasten the landing gear to the fuse with (2) 4
mm nuts and washers, use thread lock.
80. Use the inside ply brackets as a guide to open the
fiberglass up with a ½” hole. Mark the wheel
pants, one left and one right side.
© 2001 Lanier R/C Page - 10

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
81. Bolt the axle through the landing gear with the
axles pointing out. Use thread lock on the bolt.
82. Install the tip of the axle through the pant, then
the wheel and collar, then slide the assembly all
the way down the axle. Tighten the wheel collar
so that it does not bind the wheel against the
wheel.
83. Align each wheel pant to the fuse so that it is
level with the thrust line and the rear does not
drag the ground, and keep the pair equal. Drill a
small pilot hole in the fiberglass, then install a #4
x ¼” screw through the small hole in the landing
gear.
84. Locate the fuel tank and remove all the
components for assembly. Check the inside of
the tank for any dust or plastic shavings. Blow
out if needed. Notice one side of the tank has an
angle on it. With the fittings to the front, this
side faces up. You may want to mark this side
“top” with a permanent marker.
85. Bend the metal fuel tubes as illustrated on the
included instructions to fit in the tank, then insert
in the fuel stopper. Insert the clunk on the end of
the silicone fuel tubing and cut to required length
that allow it to move freely at the end of the tank.
Insert the nut and bolt in the stopper, then install
the stopper in the tank and tighten.

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
86. Slide the tank in the fuselage through the cut
opening with the metal lines out through the
firewall. Secure in place with a drop of goop or
foam.
87. Install your fuel line on the end of the tank lines
to the muffler pressure and carburetor fittings.
Make sure to allow enough extra line to the
needle valve line to give access for filling.
88. Install the lower motor box plate (the plate is ¼
thick) on the front of the fuse with epoxy.
89. Cut 2 pieces of 3/8” triangle stock, 3” long and
glue in place with ca.
90. Install the upper motor box plate on the fuse.
You can glue this plate in place as was done with
the lower, or you can glue the 3” hardwood rails
in place, then use screws to hold down the hatch.
The latter is recommended if you need to install
your battery in the front compartment to balance
your edge.
91. Test fit your top fuse hatch in place, then secure
with 2 #4 screws into the tabs at the bottom of
the hatch.
92. Trim the clear plastic canopy ¼” from the
scribed line, then test fit on the fuselage. Trim if
needed. Wash the canopy out with cool water
and dish detergent, then dry with a paper towel.
93. Now is the time to install any cockpit details,
such as dashboards or pilots (NOT
INCLUDED). Secure them firmly in the cockpit
with epoxy.
94. Install the canopy on the fuselage with epoxy or
“goop”. Hold in place with tape until cured.
95. With your engine fully set up, now reinstall the
cowling and fasten in place with the ½” #4
screws and #4 washers. Apply the (2) pieces of
white striping tape to align with the stripes on
© 2001 Lanier R/C Page - 12

LANIER – 1.20 Edge 540T ARF - INSTRUCTIONS
the fuselage. Install your prop and 3” spinner.
(We recommend Tru Turn spinners.)
96. Temporarily place your battery and receiver in
the fuse, then install the wing. You want the
plane to balance at a point 4” to 4-3/4” back
from the leading edge, measured at the fuselage
side.
97. Move your battery for or aft as needed to achieve
a balance. If needed, put the battery in the
forward compartment, behind the firewall. If
you use a lightweight engine, you may need to
put some lead in the compartment also. When
the proper radio gear position is found, wrap the
gear with foam and secure in place with Velcro
or rubber bands.
