**SUGGESTION** To avoid scratching or damaging your new airplane, do not unwrap the pieces until
they are needed for assembly. Cover your workbench with an old towel or brown paper, both to protect
the aircraft and to protect the table. Keep a couple of jars or bowls handy to hold the small parts after you
open the bags.
**NOTE** Please trial fit all the parts. Make sure that you have the correct parts and that they fit and are
aligned properly before gluing! This will ensure proper assembly. Since the Ultimate Biplane is hand
made from natural materials, every plane is unique and minor adjustments may have to be made. How-
ever, you should find the fit superior and assembly simple.
If you should find a part missing or have questions about assembly, please call or write to the address

o{1} Bottom Wing w/Ailerons & Hinges
o{1} Wing Bolt Doubler (W-24)
o{2} 4mm x 25mm Machine Screws
o{2} 4mm Washers
o{2} 4mm Blind Nuts
o1) Place the wing into the wing saddle
making sure that the preinstalled dowel in the
leading edge of the wing fully engages the
predrilled hole in the forward bulkhead in the
fuselage. Push the wing as far forward as
possible. The leading edge should fit tight
against the bulkhead.
o2) Using a ruler and pen, measure and
place a mark on the centerline of the bottom
of the fuselage at the rear of the wing saddle.
Also measure and place a mark at the
centerline of the wing at the trailing edge. See
photo # 1 below.
Photo # 1
o3) With the wing in the wing saddle, align
the two marks and hold the wing securely in
placeusing a couple of piecesof maskingtape.
o4) Remove the ailerons from the wing.
To double check that the wing is square to
the fuselage, use a ruler and measure from
each wing tip to the rear edge of the fuse-
lage. Both measurements should be equal.
See figure # 1 below.
Figure # 1
o5) When satisfied with the alignment, use
a 5/32” drill bit and drill two holes through the
wing and on through the plywood wing hold
down block. The holes are located 1-1/2” out
fromthecenterlineand1/2”forward of thetrail-
ing edge.

o6) Remove the wing from the wing
saddle. Drill out only the holes in the ply-
wood wing mounting block using a 7/32” drill
bit.
Drilling out only these holes will allow
easier installation of the blind nuts in the
next step.
o7) Install the two 4mm blind nuts from
underneath the plywood wing hold down
block. The blind nuts can be installed using
pliersby firstremoving theportion of the balsa
fillerblock directly above where theblind nuts
are installed. See photo # 2 below.

INSTALLINGTHEWINGBOLTDOUBLER
o8) Place the wing back into the wing
saddle, aligning the centerline marks. While
holding the wing firmly in place, set the wing
bolt doubler (W-24) in place. The rear edge
of the doubler should be just forward of the
rear edge of the wing saddle and the sides of
the doubler should be flush with the sides of
the fuselage.
o9) While holdingthe doublerin place,use
a pen and draw around the doubler to outline
it onto the wing surface.
o10) Removethe doubler and using a mod-
eling knife, carefully remove the covering
from just inside the outline.
o11) Mix up a small amount ofKwik Bond
5 Minute Epoxy and use it to glue the wing
doubler to the wing. Allow the epoxy to fully
cure.
o12) Remove the wing and drill out the
holes through the doubler using a 5/32” drill
bit. Use the holes already drilled through the
wing as a guide and drill down through the
top of the wing.
INSTALLINGTHEWING
o13) Place the wing back into the wing
saddle. Secure the wing in place using the
two 4mm x 25mm machine screws and two
4mm washers. See photo # 3 below.

o{1} Horizontal Stabilizer w/Elevator Halves
and Hinges
o1) Using a modeling knife, carefully re-
move the covering from over the stabilizer slot
precut in the rear of the fuselage. The slot is
located about 3” up from the bottom of the fu-
selage. There is a precovered wood spacer at
the end of the slot. It is not glued in and should
be removed and saved. See photo # 4 below.

o2) Remove the elevator halves from the
stabilizer. Using a ruler and pen, locate and
mark the centerline of the horizontal stabi-
lizer at the trailing edge and place a mark.
Use a triangle and extend this mark, from
back to front, across the top and bottom of
the stabilizer.
o3) Slide the stabilizer into the slot. The
stabilizer should be pushed firmly up against
the front of the slot, leaving about 1-1/2” of
space between the trailing edge and the rear
of the fuselage.
o4) With the wing still attached to the fuse-
lage, align the centerline mark on top of the
stabilizer with the centerline of the fuselage at
the rear. When that is aligned hold the stabi-
lizer in that position using a T-pin and align
the horizontal stabilizer with the wing. When
viewed from the rear, the horizontal stabilizer
should be level with the wing. If it is not level,
use sandpaper and sand down the high side of
thestabilizermountingplatformuntilthe proper
alignment is achieved. The tips of the stabi-
lizershould alsobe equal distancefrom thetips
of the wing. See figures # 2 and # 3 below.
o6) With the stabilizer held firmly inplace,
use a pen and draw a line where it and the fu-
selage sides meet. Do this on both the right
and left sides and top and bottom of the stabi-
lizer.
o7) Remove the stabilizer. Using the lines
you just drew as a guide, carefully remove the
covering from between them, using a model-
ing knife. See photo # 5 below.

Figure # 3
o5) When you are satisfied with the align-
ment, hold the stabilizer in place with T- pins
or masking tape, but do not glue at this time.

When cutting through the covering to re-
move it, cut with only enough pressure
to only cut through the covering itself. Cut-
ting into the balsa structure may weaken it.
o8) When you are sure that everything is
aligned correctly, mix up a generous amount of
KwikBond30MinuteEpoxy. Applyathinlayer
to the top and bottom of the stabilizer mounting
area and to the stabilizer mounting platform on
the fuselage. Set the stabilizer in place and re-
align. Double check all of your measurements
once more before the epoxy cures. Hold the sta-
bilizer in place with T-pins or masking tape and
removeanyexcessepoxyusingpapertowelsand
rubbing alcohol.
o9) After the epoxy has fully cured, install
the precovered spacer that you removed earlier

move the covering from over the stabilizer slot
precut in the top rear of the fuselage.
o2) Removethe rudderfrom the stabilizer.
Slide the stabilizer into the slot in the top of
the fuselage. The rear edge of the stabilizer
should be even with the rear edge of the fuse-
lageand itshould befirmly pushed down com-
pletely into the slot.
o3) Using a pen, draw a line on each side
of the vertical stabilizer where it meets the top
of the fuselage.
o4) Remove the stabilizer. Using a mod-
eling knife, remove the covering from below
the lines you drew. Also remove the cover-
ingfrom the bottomedge of thestabilizer. See
photo # 7 below.

When cutting through the covering to re-
move it, cut with only enough pressure
to only cut through the covering itself. Cut-
ting into the balsa structure may weaken it.
o5) Set the vertical stabilizer back in place.
Using a triangle, check to ensure that the ver-
tical stabilizer is aligned 90º to the horizontal
stabilizer. See figure # 4 below.
Figure # 4
MOUNTINGTHEVERTICALSTABILIZER
o6) When you are sure that everything is
aligned correctly, mix up a generous amount
of Kwik Bond 30 Minute Epoxy. Apply a
thin layer to the mounting slot in the top of
the fuselage and to the sides and bottom of
the vertical stabilizer mounting area. Set the
stabilizer in place and realign. Double check
all of your measurements once more before
the epoxy cures. Hold the stabilizer in place
with T-pins or masking tape and remove any
excess epoxy using paper towels and rubbing
alcohol. Allow the epoxy to fully cure before
proceeding.
PARTS REQUIRED
TOP WING MOUNTING
ALIGNTHETOPWING
o{1} Top Wing w/Ailerons & Hinges
o{1} Wing Cabane Shim (D-31)
o{2} Outboard Interplane Struts
o{4} 3mm x 16mm Machine Screws
o{8} 3mm Flat Washers
o{4} 3mm Blind Nuts

Set-up is extremely important in any air-
plane. However, wing incidence is criti-
cal in a biplane to achieve proper flight per-
formance. Incidence is the angle the flying
surfaces flow through the air. The Ultimate
shouldbe set with the stabilizerat 0º,the lower
wing at 0º, and the top wing at 0º or -1º inci-
dence. The following installation procedures
explain how to achieve proper initial setup.
See figure # 5 below.
Figure # 5
o1) With the bottom wing installed, set the
airplane upright in an airplane stand.
We highly recommend using a stand.
Theycanbe purchased separatelyormade
yourself using items found around your shop.

o2) With the airplane setting in the stand,
attach an incidence meter to the horizontal sta-
bilizer. Adjust the airplane in the stand until the
incidence meter reads 0º. Seephoto # 8below.
Photo # 8
o3) Use rubber bands or weights to hold
the airplane in position in the stand. It needs
to be secured so it cannot be moved during
the next few steps. After you are satisfied it
has been secured properly, recheck the stabi-
lizer incidence to ensure it is still at 0º.
o4) Remove the incidence meter from the
stabilizerand attach it to thebottom wing. The
incidence meter should read 0º as well.
If the incidence meter does not read 0º
then recheck the incidence of the stabi-
lizer to ensure it has not moved. If you are
certain it hasn't, recheck the incidence of the
bottom wing. You should make small adjust-
ments to the wing saddle until the incidence
meter reads 0º on the bottom wing.
o5) Working with the topwing, first iden-
tify the bottom surface of it. If you look
closely, two ribs in from each tip, there is a
precut slot that is 2” long and accepts the outer
interplane struts. This is the bottom of the
wing. Using a modeling knife, remove the
coveringfrom over thesetwo slots. Seephoto
# 9 below.
Photo # 9
o6) Locate and remove the covering from
over the two predrilled wing hold down holes
in the top wing. These holes are located down
the centerline of the wing. The forward hole
is located 7” in front of the trailing edge and
the rear hole is located 3-5/8” in front of the
trailing edge. Remove the covering from both
the top and bottom of the holes.
o7) Mount the top wing to the aluminum
cabane struts using the 3mm x 50mm machine
screw in the front, the 3mm x 35mm machine
screw in the rear. Use four 3mm washers and
two3mm lock nuts to securethe wingin place.
If the holes in the wing do not align with
the holes in the cabane struts loosen the
strut screws further to allow the metal parts to
adjust to the wing. The screws will be com-
pletely tightened after the wing alignment has
been set. See photo # 10 below.

INSTALLINGTHEINTERPLANESTRUTS
o8) Locate the two outer interplane struts.
There is a top and bottom to the struts. There
aretwopredrilled holesinoneend ofeachstrut.
Where these two holes are located is the bot-
tom of the strut. Using a modeling knife, re-
move the covering from over these holes on
both sides of each strut. See figure # 6 below.
Figure # 6
o9) Onthe topsideof thebottomwing there
are two slots for the struts similar to those in the
topwing . Thesetwo slotsare locatedjust tothe

the covering from over these holes.
o11) Install one 4mm blind nut in each of
thefourholes inthestrut mountingblocks. The
blindnutsshouldbe mounted ontheinsideedge
of the blocks. See photo # 11 below.
o12) Remove the top wing. Plug the two
interplane struts into the corresponding slots
in the bottom of the top wing. The predrilled
holes in the struts should be on the bottom
andthe edge of the strutscovered inred should
face the leading edge of the wing.
o13) Reinstall the top wing making sure
the two outer interplane struts completely en-
gage the two slots in the top side of the bot-
tom wing.
o14) Securetheouterinterplanestrutsinplace
usingthefour 3mm x16mmmachinescrews and
four3mmflatwashers. Themachinescrewspass
through the strut and thread into the blind nuts
installed in the mounting blocks.
Photo # 11
o15) Remove the ailerons from the top
wing. Attach the incidence meter to the top
wing and check the incidence. The meter
should read either 0º or -1º.
If the incidence meter does not read 0º
or -1º then you may need to adjust the
metal cabane struts and /or shim the space
between the rear metal cabane strut and the
wing. We have provided a hardwood cabane
shim (D-31) for this purpose.
MOUNTINGTHETOPWING
o16) When completely satisfied with the
alignment of the top wing use threadlock on all
ofthe metal cabanescrews and nutsand tighten
them completely to lock the wing's alignment
in place.
o17) Using a pen draw a line on each side
of the outer interplane struts where they meet
the bottom surface of the top wing.
o18) Remove the top wing and outer
interplane struts. Using a modeling knife, re-
move the covering from the interplane struts
from just inside the lines you drew on them.
o19) Mix up a generous amount of Kwik
Bond 30 Minute Epoxy. Glue the outer
interplane struts into the TOP WING ONLY.
Before the epoxy cures, reinstall the top wing
and secure the interplane struts into the bottom
wing with the four machine screws. Allow the

Photo # 17
o2) Mark the locations of the four engine
mounting holes on the beams using a pencil.
For the engine to align properly with the front
of the cowling, it is important that the front
edge of the engine's drive washer be 4-7/8”
forward from the rear edge of the mounting
beams.
o3) When satisfied with the alignment of
the engine, remove the beams from the
clamp and drill 1/8” holes through the
mounting beams at the four engine mount-
ing hole locations.
o4) Mount the engine to the mounting
beams using the four 3mm x 25mm machine
screws,eight 3mm flatwashers, four 3mmlock
nuts. Tighten the screws and nuts completely.
If using an engine equipped with a re-
mote needle valve we recommend
mounting the needle valve to the engine prior
to installing the engine on the motor mount
beams.
ALIGNINGTHEMOTORMOUNT
o5) The engineis mountedsideways on the
firewall. Using a ruler and pen, measure and
draw a vertical centerline on the firewall.
o6) Measure down from the top of the fu-
selage 1-1/2” and draw a horizontal line on
the firewall. See photo # 18 below.

o2) Mix up a small amount of Kwik Bond
5 Minute Epoxy. Use a couple of small dabs
of epoxy to glue the balsa gear cover (D-29)
onto the aluminum gear, flush with the bot-
tom of the fuselage.
There are three holes predrilled through
the block that allow the screws to be re-
moved should the gear need servicing. You
can leave these holes covered by the covering
or remove the covering from over them now
using a modeling knife.
INSTALLINGTHEWHEELPANTS
o1) Working withone wheelpant ata time,
use a Dremel Tool and remove the plastic that
covers the wheel opening on the bottom of
the wheel pant.
Look carefully at each side of the wheel
pantand youwill notice amolded dimple.
One dimple is about 1/8” higher on one side
than the other. If you will be flying off a hard
surfacewe recommend youdrill outthedimple
that is higher. If flying off of grass we rec-
ommend you drill out the dimple that is lower.
This will raise the wheel pant higher on the
axle and give more clearance between the
wheel pant and the ground.
o2) Using a 5/32” drill bit, drill out only
the one dimple that you choose.
o3) Using a modeling knife, cut a slotfrom
the hole down to the wheel pant opening. See
photo # 26 below.
Photo # 26
o4) Slide one 60mm diameter wheel onto
one 4mm x 35mm axle screw. The wheel
should go on with flat side of the hub first.
o5) Slide two 4mm nylon spacers over the
axle screw and up against the wheel. Thread
one 4mm hex nut onto the axle screw.
o6) Tighten the hex nut against the nylon
spacers as tight as it can be, but still allow
the wheel to spin free on the axle. Secure
the nut in place by carefully applying a couple
of drops of Kwik Bond Thick C/A to the
threads. Allow the C/A to fully cure. See
photo # 27 below.
Photo # 27
o7) Slide one 4mm washer over the axle
screw and up against the hex nut. Carefully
slip the wheel and axle assembly into the
wheel pant. The axle screw should slip firmly
into the slot in the wheel pant and the flat
washer should be positioned inside the wheel
pant.
o8) Slide the axle bolt through the pre-
drilled 4mm hole in the aluminum gear
bracket and secure in place using one 4mm
lock nut. Tighten the lock nut completely,
at the same time making sure the hex nut does
not come loose. Double check that the wheel
does not bind when rotated.
o9) Repeat steps # 1 - # 8 for the opposite
side.

the pushrod housing enters the servo compart-
ment from the rear bulkhead.
o9) Using a modeling knife, cut off the
pushrod housing at this mark.
o10) Slide the pushrod back into the
pushrodhousing. Snap the clevis onto therud-
der control horn and use a couple of pieces of
masking tape to hold the rudder in neutral.
o11) Locate a long servo arm and using
wire cutters, remove all but one of the arms.
Install the L-bend in the 85mm wire into the
outer hole in the servo arm. Secure the wire
in place using one nylon snap keeper.
o12) With the rudder and rudder servo in
neutral, install the servo arm onto the servo.
The arm should be positioned perpendicular
to the fuselage sides.
o13) Using a pen, place a mark on the ny-
lon rudder pushrod where the tip of the wire
overlaps it. Use a modeling knife and cut off
the nylon pushrod 5/16” ahead of the mark.
This will leave enough space so the threaded
wire can thread into the pushrod at least 5/16”.
o14) Thread the wire into the pushrod.
You can thread it in further or back it out to
achieve the correct length.
o15) When satisfied with the alignment,
install the servo arm set screw and remove the
masking tape from the rudder. See photo #
35 below.

o16) Move the rudder back and forth.
Theremay be someflex presentin the pushrod
just before it gets to the rudder servo. If so,
glue one pushrod support (D-32) between the
pushrod housing and the servo tray using a
small amount of Kwik Bond 5 Minute Epoxy.
See photo # 35 above.
