Thank you for your patronage to East R/C! Your support of our products is tremendously
appreciated. We are a family owned and operated company and are avid R/C modelers,
just like you. By purchasing our products you enable us to produce more products for our
modeling friends across the globe. Thank you!
The SLEDG is designed to be a lightweight 3D foamy, capable of any 3D maneuver in the
book while feeling much lighter on the stick than that of a traditional foamy airplane.
Build time should be around 2 hours and we have included a Landing Gear option, should
you choose to use it. The hardware package is of only the best quality available to us and
we have left no stone unturned. Everything you need, less power plant and radio system,
is included. So, get to building and please, let us know what you think. Your feedback
helps us to better improve upon our products.
Thanks again!
East R/C

Painting Foam:
If you want to paint your SLEDG, it is usually best to dress it up before assembly of the
kit. Be mindful of the paint you intend to use. Most spray paints are not foam safe and if
you use the wrong paints, your foam will transform from a solid to a liquid in relatively
short period of time. There are several paints available that are foam safe. Here are a few:
1. Testors Model Car Spray Paint
2. Tamiya Model Car Spray Paint
3. Krylon Short Cuts
4. Foam Spray Paint from your local arts & crafts store
5. Most airbrushed acrylics
You can create masks from thin posterboard and other materials that will allow you to
create cool effects. If you are interested in learning more about techniques for painting
foam airplanes, go to this thread at FlyingGiants.com:

p
1. Lightly sand all of the foam parts edges
before assembly.
p
2. Locate the left & right wing panels and
use a piece of wax paper underneath to
catch any excess glue.
p
3. Apply a bead of foam safe glue down the
mating side of the wing panels.
p
4. Pull them together, aligning the the
pre-cut wing spar groove, and spray with
foam safe accelerator.
p
5. Locate and test fit the Carbon Fiber
Wing
Spar into the wing.
p
6. Run a bead of foam safe glue down the
length of the groove press in the spar & spray
with foam safe accelerator.
Page: 7
p
7. Spar installed.
p
8. If you don't have someone to help you,
use 2 weighted objects to hold the wing
while installing the leading and trailing edge
carbon fiber strips.
p
9. Locate the full length carbon fiber strip
and prepare to apply it to the leading edge.
p
10. Mark a line on the leading edge at 8.5"
and glue from that point down to the
opposite wingtip.
p
11. Place the carbon fiber strip on the
leading edge, starting at the mark,
running the length to the opposite wing
tip, then spray with accelerator.
p
12. If the scab piece is too long, mark it
with a pencil as shown.
Page: 8
p
13. If you do not have a pencil, you can
score a mark with your hobby knife.
p
14. Cut the trip to your marked length
with a back and forth, sawing motion. Glue
The piece to the remainder of the leading
edge.
p
15. Leading Edge Complete:
p
16. Flip the wing over, leading edge down, &
Glue the trailing edge strips on..
p
17. Trim tips if necessary to remove any
over hang.
18. Trailing Edge Complete:
p
Page: 9
p
19. Prepare the Horizontal Stab &
Horizontal fuse sections for gluing.
p
20. Check the fit to make sure the stab is
not upside down before gluing.
p
21. Run a bead of foam safe glue onto
each surface.
p
22. Hold the pieces firmly together and spray
with accelerator.
p
23. Slide the bottom fuse section onto the
horizontal fuse section, starting at the nose.
p
24. Make sure the firewall area is
aligned properly.
Page: 10
p
25. Press the keys into the horizontal fuse
section carefully.
p
26. Make sure not to get glue into the empty
key slots.
p
27. Run a bead of glue the length of the
mating pieces on both sides.
p
28. Spray with accelerator
p
29. Your fuse should now look like this:
p
30. Test fit the top fuse section, but do not
glue.
Page: 11
p
31. If needed, mark a line where these
2 pieces meet.
p
32. Remove the top fuse section.
p
33. Trim the part with your hobby knife.
Using fresh blades every few cuts will
ensure that there are no tears in the foam.
p
34. The top fuse section trimmed and ready
to re-install.
p
35. Check that these meet up well.
p
36. Leave this slot open. You will have to pass
the elevator through this slot later.
Page: 12
p
37. Glue the top fuse section to the
rest of the fuse.
p
38. The fuse main section is complete:
p
39. Slide the wing through the wing slot
on the fuselage. Trim the slot with your
hobby knife if needed. Don't force it.
p
40. Align the wing to the horizontal stab
with a string or tape measure. Position
the wing so that the measurement is the
same on both sides.
p
41. Glue the wing to the fuselage.
p
42. Your SLEDG should look like this:
Page: 13
p
43. Locate the rudder, elevator & ailerons
for hinging.
p
44. Measure in 1/8" and mark at both ends
of the hinge line.
p
45. On a smooth surface and using a
a straight edge, draw a line from mark
to mark.
p
46. Completed bevel:
Cut at an angle, using the straight edge as a
guide, not quite cutting through to the other
side.
p
Page: 14
p
p
48. Use a flat surface for the hinging of the
ailerons and a weight to hold the airplane
steady. Maintain a gap of 1/6"-3/32"
between surface and airplane.
p
49. Note the gap. Fold surface over and hinge
the opposite side, as well with the included
Blenderm.
47. Repeat the process for the elevator &
ailerons.
Page: 15
p
50. Sand the edges & surface of the firewall.
p
51. You can use 5 Minute Epoxy or Hot
Glue for the firewall. I will show the
Epoxy method here.
p
52. Dispense equal parts of hardener &
resin on a piece of something disposable.
p
53. Mix the epoxy with a piece of scrap balsa
or foam and apply in a "Cross" pattern, like
shown:
p
54. Install on the airplane.
p
55. Apply a bit of epoxy behind the firewall,
as well.
Page: 16
p
56. Locate the control horns.
p
57. Carefully push the horns pegs through
the surface. Keep the leading edge of the
horns base aligned to the trailing edge of
the surfaces bevel.
p
58. Clean out any foam that may be pushed
out of the holes.
p
59. Add a bit of glue to each side and
press on the retainer clip.
p
60. Note the horns location, compared to
the travel of the elevator.
p
61. Horn placement is best in an area that
will prevent horns and linkages from
interfering with the travel of the surface.
Page: 17
p
62. Repeat for the remainder of the
surfaces.
p
63. Locate 2 "L" bend linkages, the 2
straight wire linkages & the 2 carbon fiber
tube pushrod mid sections.
p
64. Roughen the wire with sand paper and
glue one end into the carbon tube as shown.
Wrapping the glue joint with thread and
glue can add strength to the joint.
p
65. Depending on where you cut in your
elev. & rud. servos, you may have to trim
the carbon fiber tube down a bit in length.
p
66. 2 completed tail section pushrods:
Page: 18
p
67. Attach the "L" bend side to the control
horns and push on the retainer clips.
p
68. Using the linkage as a guide and your
servo as a template, mark for the servo
locations for both rudder & elevator.
p
69. Using a fresh #11 blade, cut the slots
out with your hobby knife.
p
70. Check the fit of the servos. Once satisfied
with the fit, glue them in place.
p
71. Mark the ailerons servo locations, using
the 2 remaining "L" bend linkages and your
servo as a guide.
Connect the pushrods to the servo arms with
the included EZ connectors.
Page: 19
p
72. Connect the linkage at the horn
with the clear plastic keepers and at the
servo arm with the EZ connectors.
p
73. OPTIONAL: Locate the landing gear
side plates and glue one to each side of the
bottom fuse section with the center lined
up with the leading edge of the wing.
p
74. Check to make sure your batter will
clear the plates.
p
75. For the side plate pegs, you will need a
3/6" drill bit.
