Biplane
Flying weight: Approx. 6 -7oz. (with recommended setup)
Wing Span: 21 1/2"
Wing Area: 240 sq. inches
Wing Loading: 3.6 oz./ sq. ft.
Length: 18”
Introduction:
The MicroSSX™Biplane Build Kit is a fun-to-fly and build classic biplane version of the popular Millennium
R/C MicroSSX airplane. The MicroSSX™Biplane has the same wing span and length as the original Micro
SSX™, and is similar in that it is aerobatic and can handle the wind fairly well, but the Biplane is capable of
sustaining slower flight due to its lower wing loading.
Adult supervision recommended for children 15 and under. R/C Airplanes should be flown following safety
guidelines provided by the AMA (Academy of Model Aeronautics).
CAUTION: This is not a toy!
Recommendations:
1. Read through each step before starting assembly.
2. After removing all the pieces from packaging, inspect to make sure there are no broken or missing parts.
3. Check off each completed step to help keep from losing your place.

MicroSSX™Biplane Build Kit Assembly Instructions Rev. 2

IMPORTANT:
DO NOT GLUE UNTIL INSTRUCTED TO DO SO!
Assembly Instructions:
1. Cut-don’t break, the balsa and plywood parts from
the parts sheets. Breaking the parts out of the sheets
can damage the parts. The top of each wing is
identified by the installation of the main spar. The
main spar is always installed from the TOP. You
may sand away excess material from break-away. If
desired, may also sand away any laser burn.
2. Build 2 W1B ribs from W1B, W1b and W1bb.
(Glue) Fig 1
Figure 1
3. Build 2 W2B ribs from W2B, W2b and W2bb.
(Glue) Fig 2
Figure 2
4. Build 2 frames from LE, TE and W2C. (Glue) Fig 3
Figure 3
5. Install Ribs W1A, W1B, W6 and W7 and Ply wood
pieces P11/P11A, P9 and P10 for the bottom wing
(No Glue) Fig 4
Figure 4
6. Install Ribs W2A, W2B, W6 and W7 Ply wood
pieces P22/P16, P9 and P10 for the top wing. (No
Glue) Fig 5

Tack glue ribs to TE. Set wings on flat surface,
square all parts and glue with thin CA. Fig 6

8. Install wing tips.W8 and W9. Slice the two parts in
half to install. It will be necessary to bevel W9
where it joins with W8. (Glue) Fig 7

12. Build Vertical/horizontal stabilizer and
rudder/elevator as shown in Fig11 and 12 on
attached sheet. (See BP-HS.WMF and BP-
VS.WMF) 2 Plywood pieces “PS1” should be
doubled-up to make the leading edge of the elevator.
13. Bevel bottom elevator 45 °, one side of rudder and
bottom of ailerons. Remember to mirror the ailerons.
14. Using a fine sandpaper, sand all tail surfaces, round
all edges, and taper leading edges of all control
surfaces, including ailerons.
15. Cover wings and tail with light model covering such
as Solite or World Models Lightex. Apply decals as
desired.
16. Cut openings in covering. Gray areas indicate
uncovered openings. Fig 13, 14 and 15. Make sure
wings are true and flat after covering. A twisted
wing can be corrected withopposite twist.

21. The biplane has 8-0.060” diameter carbon struts. 4
wing struts, 2 front and 2 center cross struts.
a. Wing struts: 4.840”
b. Front struts: 2.675”
c. Center cross struts: 5.000” (May need to be
trimmed during installation)
To cut the carbon rods, use a sharp Exacto knife
and a rolling action.
The cross struts are installed last.
Make sure they bottom out in the slots. Also
make sure each set is exactly the same length.
Do not install them until all warps are ironed out
of the wings and told to do so in the instructions.
Set them aside for now.
Final Assembly
22. Tape a length of Scotch tape™ along the rear
trailing edge of the horizontal stabilizer and secure
with your finger (either side is fine). Now, flip the
stabilizer and place on a work surface. See diagram
below:
23. Now, take the elevator. You will see that the
elevator has a ‘beveled’ edge. This is important in
creating the hinge. Ensure that the beveled edge is
pointing up, and while holding at a 45° angle, place
up against the trailing edge of the horizontal
stabilizer and secure the hinge tape to the elevator
with your finger. See diagrams below:
24. Turn the stabilizer assembly over, and carefully fold
the elevator back onto the stabilizer.
25. Tape another length of Scotch tape™ along the
bottom hinge line and secure with your finger.
26. Fold the elevator back to normal position. Test the
hinge by pulling gently on the control surface. Cut
off any excess tape overhanging the stabilizer sides.
27. Repeat the steps 21. thru 26. for the rudder and
ailerons.

28. Build the servo tray. Fig 20
Figure 20
Figure 21
29. (Fig 21) Slide P12A onto the fuselage stick and
glue 6-1/4” from the tail end. Slide P12 onto the
fuselage and leave it loose. Slide the tail mount
onto the fuselage end and align it so that it is
square with the flat edge of P12A. Glue it and
allow the glue to dry. Secure P12 to P12A with
2 #0-1/4 screw. Do not glue P12 to P12A. Slide
the servo assembly onto the front of the
fuselage, align it so that it is square with the flat
edge of P12A and glue it with CA glue.
30. Slide the fuselage assemblythrough the front
lower wing mount. P12 should be glued into the
slot on the trailing edge of the wing. Align the
wing so that it is parallel to the tail mount. Glue
the tail section vertical and horizontal stabilizer
together so they are square. Glue the tail
assembly to the tail mount. Make sure it is
parallel with the wing. Fig 22, 23 and 24
Figure 22
Figure 23
Figure 24
31. Slide the landing gear assembly onto the
fuselage. Align it parallel to all other
components. It should be 2-1/32” from the front
end of the fuselage. Fig 25

32. Install four 4.840” carbon wing struts. Make
sure struts are fully inserted into the wing before
gluing with thin CA. Fig 24
33. Install two 2.675” front struts. Make sure struts
are fully inserted before gluing with thin CA.

adjusted to “0” using the adjustable rear wing
saddle P12.
Control throws: Rudder Full deflection
Elevator 20 degrees
Ailerons 20 degrees
More extreme throws can be used as desired.
