safety of these batteries.
Recommended building methods and glues:
Muc of t e construction of t is model is done by
laying t e parts on a flat table. It is strongly
recommended t at you put wax paper down on t e
surface first so any excess glue doesn’t soak t roug
t e foam and glue t e parts to t e table. For all
assembly, use “Welders” contact ad esive. T e inges
are also done wit Welders, see our video on t e web
site. Hot glue can be used to attac t e servos and
control orns.
Starting out:
Look over t e parts and dry fit t em toget er to c eck
for proper fit.
Painting:
It is easiest to paint t e parts before assembly. Card
stock can be used to make templates for stripes,
c eckers, ect... Epp does is not affected muc by
solvents so Krylon, Testors and airbrus paints can be
used.
Horizontal parts assembly:
Glue t e spar tube into t e slot in t e bottom of t e
wing.
Cut a 6” long piece of 1.5mm carbon pus rod. Cut a v-
slot in t e bottom of t e elevator just be ind t e inge
bevel and glue in t e 6” carbon piece.
1

Hinge t e ailerons to t e wing and t e elevator to t e
orizontal stabilizer. (A Welders glue inge
instructional video is on t e web site.)
Glue toget er t e orizontal pieces; nose, wing, rear
fuselage and orizontal tail. Note: T e wing spar goes
on t e bottom and t e aileron and elevator inges go
on top.
Lower fuselage to horizontal – Assembly:
If using a stick mount, cut a slot in t e orizontal nose
piece and glue t e mount in place. For a firewall plate
wait until t e airframe is built before installing. Set
motor mount wit NO rig t or down t rust. It is not
required.
If installing a single aileron servo t en cut a pocket
for it now in t e nose piece. Lay t e vertical pieces on
t e orizontal assembly to mark and cut clearance
pockets for t e aileron servo.
Glue t e lower vertical fuselage pieces to t e
orizontal assembly making sure it is square.
Now is t e time to add carbon bracing to t e tail. Cut
t e 1mm carbon rod into 2 – 3.5” pieces and 6 – 5.25”
pieces. Glue t em per t e picture wit otglue.

Landing Gear (optional):
Cut 2 pieces of t e 1.5mm carbon, 8” long and two
pieces 1” long. Glue t em toget er as s own wit a
1/8” overlap at a 45 degree angle. Cut a 6” piece of
string and wrap t e joint wit it in two directions. CA
t e string to secure t e axel.
Install t e gear legs t roug t e vertical fuselage and
into t e bottom of t e wing, just be ind t e leading
edge, but not t roug t e wing. W en you ave t e
axles parallel and even glue t e gear legs in place.
Glue t e gear pant to t e gear leg and t e fuselage side.
Slide t e w eels onto t e axels. Slide t e w eel pant
onto t e axle and secure in place wit a drop of CA
leaving enoug room for t e w eel to spin freely.
Final assembly:
Install t e aileron servo and glue t e top vertical
fuselage to t e main assembly. T en cut pockets and
install t e tail servos. T e rudder servo goes on t e
left.
Hinge t e rudder to t e aft of t e vertical fuselage
pieces.
Install t e motor onto t e motor mount and velcro t e
speed control and receiver to t e lower left side of t e
fuselage.
Use an exacto knife to slot t e control orn locations in
t e ailerons, elevator and rudder. Glue t e orns in
place.
Wit all t e surfaces set to zero, measure t e distance
between servo arm oles and control orn oles. Cut a
piece of 1.5mm carbon rod for eac pus rod to t e
measured lengt s. Cut a 1.5” long piece of 1/32” wire
and make a z-bend on one end. Slide a 1” lengt of
eat s rink over eac end of t e carbon rod and t en
slide in a z-bend wire. S rink t e eat s rink tubing
wit a eat gun or flame. T e z-bend wire is not glued
in position yet and can be moved for final adjustments.
Remove t e servo arm and assemble t e pus rods to
t e servo arm and control orns. Wit t e servo
centered reattac t e servo orn. Make any final
adjustments to t e z-bend location. Use regular (not
foam safe) t in CA to secure t e z-bends to t e pus
rods by placing a drop at eac end of t e eat s rink
tubing. If you get some CA on t e servo or control orn
t is is ok and moving t e controls will allow t e z-
bend to break loose.
Note: T is pus rod setup will act to save your servos.
In t e event of an impact t e glue olding t e z-bend to
t e pus rod will likely give before t e servo gears. If
t e z-bends start to slide in t e eat s rink a drop of
CA will secure t em again.

Motor installation
Install t e motor into t e stick motor mount and velcro
t e speed control and receiver to t e lower left side of
t e fuselage.
Flight set-up:
Use double stick Velcro on t e battery and airframe to
secure t e battery to t e bottom of t e orizontal
fuselage in a location t at gives t e model proper
balance. Adjust t e battery location back and fort to
suit your flying style. Use your computer radio to set
t e final sub-trims, exponential and dual rates. Double
c eck t e control directions before your first flig t.
With proper CG, the plane should fly nearly the
same upright or upside-down. Good pilots
experiment wit various battery locations until t e CG
feels just rig t.

For indoor flying, we use 2 or 3 cell lipo packs rated at
20C. Batteries of 300 to 480 ma are perfect for
giving good flig t times and plenty of power. T e final
airplane weig t s ould be between 6.0 and 7.5 oz.
Center of Gravity:
Yak-55 is 2.75” be ind t e leading edge of t e wing.
Yak-54 is 2.75” be ind t e leading edge of t e wing.
Edge 540 is 3.5” be ind t e leading edge of t e wing.
Sbac 342 is 3” be ind t e leading edge of t e wing.
