Fuselage Assembly
1. Fit battery tray base BT2 to F2
2. Fit battery tray sides BT1 to F2/BT2
3. Fit F1 to battery tray BT1/BT2. Ensure all parts are fit
together square and tight and then glue together.

4. Glue F1A to the back of F1.
5. It is recommended to fit your motor to F1 at this time.
You will need to route a hole for your motor wires to
pass through
6. Fit former F3 to the electronics/servo tray ST. Ensure
ST is perpendicular to F3 and glue together.
7. Fit and glue the fuselage side pieces together as
shown in the illustration below this text. Fit to the
fuselage side. Fit F4 and F5 to the fuselage side, but
do not glue yet.

8. Fit and glue the other fuselage side to F3/ST. Bring the
rear of the fuselage sides together and secure with
tape, do not glue them together yet.
9. Fit the fuselage bottom to the fuselage sides. Ensure
the joints are tightly fit together and that the sides are
square to the bottom and then glue them together.
10. Fit and glue the top of the fuselage to the fuselage
sides.
11. If you intend to install floats, epoxy LG2 to the inside
of the fuselage bottom. If you do not plan on ever
installing floats, skip to step 13.

12. Cut two pieces of the included balsa triangle 2” long
and epoxy to LG2 and the fuselage sides.
13. Fit the battery tray assembly to the fuselage sides.
Ensure all parts are fully seated and that the fuselage
sides are straight (no twist) and then glue the battery
tray assembly to the fuselage sides.
14. Epoxy LG1 to the inside of the fuselage bottom. This
step is a little tricky because you have to work around
a number of other parts, so practice placing LG1
before applying any epoxy.
15. Cut two pieces of the included balsa triangle 2” long
and epoxy to LG1 and the fuselage sides.

16. Fit and glue the fuselage doublers FD in place as
shown.
17. Cut two pieces of 3/16” carbon rod so that they stick
out from both sides of the fuselage about 5/8” and
slide them into the fuselage. DO NOT glue them in
place!
18. Fit and glue F2A to fuselage former F2 as shown, be
careful not to glue F2A to the carbon rod. Sand a
bevel on the top of F2A to match the fuselage sides.
Remove the carbon rod when done.
19. Fit and glue F3A to fuselage former F3 as shown, be
careful not to glue F3A to the carbon rod. Sand a
bevel on the top of F3A to match the fuselage sides.
Remove the carbon rod when done.

horizontal stabilizer. Sand and cover the horizontal
stabilizer.
26. Join the elevator halves with a 3” piece of the
included 1/8” dowel, use the horizontal stabilizer to
ensure the elevators are spaced apart appropriately.
Sand and cover the elevators.
27. Use tape to join the elevators to the horizontal
stabilizer. Cut the covering from the slots in the
BOTTOM of the horizontal stabilizer and it to the
fuselage. Using the fuselage sides as a guide, cut and
remove the covering from the bottom of the stabilizer
where it meets the fuselage. Ensure the horizontal
stabilizer is straight and square to the fuselage and
glue in place.

28. Cut the covering from the slots in the top of the
fuselage and horizontal stabilizer for the vertical
stabilizer. Fit the vertical stabilizer to the fuselage and
using it as a guide, cut and remove the covering from
the fuselage/horizontal stabilizer where it meets the
vertical stabilizer. Ensure the vertical stabilizer is
straight and perpendicular to the horizontal stabilizer
and glue in place.
29. Sand a 45 degree bevel on the leading edge of the
rudder. Sand and cover the rudder. Use tape to join
the rudder to the vertical stabilizer and fuselage.
30. Insert and glue the carbon rods for the wing hold
downs.
31. Install motor, speed controller and servos for the
rudder and elevator. Install control horns on rudder
and elevator and connect to servos.

32. Secure the landing gear wire to the fuselage, the
landing gear should be even with the leading edge of
the wing.

Wing Assembly
33. It is very important to remember that you will be
building a right and left wing panel. For each step you
will need to perform the same task with the parts in
left (as depicted in the illustrations) and right
orientation.
34. Fit R4 and R5 to SDB with the marked outline towards
the front of the ribs. Ensure the ribs are perpendicular
to SDB and then glue together.
35. Fit and glue WS3 to the bottom of WS2, the rib slots
on WS2 MUST be at the top.

36. Fit ribs R2 – R8 to WS2, R2 must be towards the end
of WS2 that has the marked part number.
37. Fit TE1 to ribs R2 – R8, Don’t glue yet.
38. Fit and glue together SH2A and SH2B. Fit SH2 to TE1,
R2 and wing spar, ensure all parts are fit together
tightly and then glue together. Fit and glue SH1 to
wing spar and R2.
39. Fit and glue R1 to wing spar, SH2 and SH1.

40. Fit and glue R9 to wing spar and TE1.
41. Fit and glue WS3 to wing spar. Fit and glue LE1 to R1 –
R9.
42. If you plan on adding the leading edge slats you will
need to glue the slat pockets SL1 to the outside face
(towards wing tip) of ribs R2, R5 and R8.
43. Glue SL2 to SL1. Be sure you do not get any glue into
the pocket.

44. Sand a bevel in the leading edge LE1 to match ribs R1
& R2.
45. Fit and glue 1/8” sq. sticks into the slots in the wing
ribs as shown. Slice 1/8” sq. sticks in half between R1
& R2. See step 43 below for clarification.
46. Slice 1/8” sq. sticks in half between R1 & R2.
47. Glue the 1/32” ply reinforcing disks to R1 and R2 as
shown. Use the 3/16” carbon rod to assist with
alignment but be careful not to glue the carbon rod to
the ribs.

48. Fit and glue together SH4A and SH4B. Fit SH4 to R1
and R2, ensure all parts are fit together tightly and
then glue together. Fit and glue SH3 to LE1, R1, R2
and the wing spar.
49. Fit and glue T1, T2 and T3 to R9.
50. Fit and glue WT to T1-T3 and R9.

54. Cut the included 3/16” carbon rod in half. Insert the
carbon. Test fit the two wing panels together before
gluing the carbon rod in place.
55. Apply some glue or epoxy to the root rib and join the
wing panels together. Glue the carbon rods to R2 of
the second wing panel.

56. To make the slats, apply a thin film of wood glue to
the 1/32” slat bottom that has the six small notches.
Put the 1/32” slat top on to the slat bottom and
carefully align them. Place the slat onto a 3” to 4”
diameter tube (like PVC tube) and tape down to the
tube. Apply enough tape to keep the slat completely
against the tube and allow to dry. Once dry, remove
the slat from the tube and carefully cut out the six
notches. Round over the leading edge of the slat and
sand a slight taper to the trailing edge so that it has an
airfoil like cross section. Cover the slats.
57. Carefully cut away the covering from the slat pockets
in the leading edge of the wing panels. Fit the 1/16”
ply slat supports into the pockets, DO NOT glue them
in if you want the slats to be removable.
58. Carefully fit and glue the slats to the slat supports.
59. Glue the 1/32” ply aileron core to the 1/32” balsa
aileron top (with the small notches).

60. Glue the 1/32” balsa aileron bottom (with the ‘T’
notches to the other side of the ply aileron core.
Round the leading edge of the aileron (edge with
notches) and then sand a taper on both sides of the
trailing edge so that the aileron has a symmetrical
airfoil profile. Cover the aileron and then cut away the
covering from the hinge slots.
61. Cut six 1” pieces of 1/32” carbon rod and insert into
the aileron hinges.
62. Fit the aileron hinges into the hinge slots as shown.
Carefully glue the rods into the slots but be careful
not to glue the aileron hinge to the carbon rod.
63. Cut away the covering from the hinge slots in the
trailing edge of the bottom of the wing. Fit and glue
the aileron hinges to the bottom of the wing.

64. Attach the servo to the servo doors. Ensure that the
servo placement does not interfere with the servo
door frame in the wing. Insert the servo door into the
wing and secure with four screws.
65. Install a control horn on the aileron and connect the
aileron to the servo.
66. Secure the wing to the fuselage with an appropriate
number of rubber bands.

Float Assembly
67. Fit F3, F4 and F5 to the 1/8” ply mount doubler,
ensure the formers are fully seated and perpendicular
and then glue together.
68. Fit and glue formers F3-F5 to one of the float sides.
69. Fit and glue the opposite float side to formers F3-F5.

70. Fit and glue formers F1, F2 and F6 to the float sides.
71. Sheet the top of the float with 1/16” balsa, 1/32”
balsa can be used if desired.
72. It is recommended to sheet the bottom front of the
float with 3/32” balsa. Sheet the bottom rear of the
float with 1/16” balsa, 1/32” balsa can be used if
desired.
73. Glue scrap balsa to the front and back of the float.
The front should have at least ½” and the rear should
have at least ¼”. Sand the blocking flush to the float
sides and top/bottom. Round over the front blocking
as desired.
It is recommended to seal the balsa before covering.
