2)Removeeach hingefromthe wingpanel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. This will help ensure an equal amount
ofhingeisoneithersideofthehingelinewhen
the aileron is mounted to the aileron.
HINGING THE AILERONS.
3) Slide the wing panel on the aileron until
there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel.A gap of 1/64” or less

firmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully
applying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
5) Turn the wing panel over and deflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsurethattheC/Apenetratesinto

 1)Set the tail wheel assembly in placeon
the plywood plate. The pivot point of the tail
wheel wire should be even with the rudder
hinge line and the tail wheel bracket should
be on the plywood plate.
 3) Secure the tail wheel bracket in place
using two 3x10mm wood screws. Be careful
not to overtighten the screws.
 2) Using a pen, mark the locations of the
two mounting screws. Remove the tail wheel
bracket and drill 1mm pilot holes at the loca-
tions marked.
MOUNTING THE TAIL WHEEL.
1) Align the tail wheel wire so that the wire
is parallel with the bottom of the rudder. The

while sliding the clasp over the bottom of the
rudder.
3) While holding the clasp firmly in place,
use a pen and outline the clasp onto the rud-
der.
4) Remove the clasp, and using a model-
ing knife, remove the covering from inside the
lines you drew. Use 220 grit sandpaper and

1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
yourplanetolosecontrol andcrash. The cen-
ter of gravity is locate 7.5-8cm back from
theleadingedgeofthewing,measuredatwing
tip.
BALANCING.
7.5 - 8cm.
2) If the nose of the plane falls, the plane
is nose heavy. To correct this first move the
battery pack further back in the fuselage. If
this is not possible or does not correct it, stick
small amounts of lead weight on the fuselage
sides under the horizontal stabilizer. If the tail
of the plane falls, the plane is tail heavy. To
correctthis,movethebattery andreceiverfor-
ward orif this is not possible, stick weight onto
the firewall. When balanced correctly, the air-
plane should sit level or slightly nose down
when you lift it up with your fingers.
CONTROL THROWS.
1) We highly recommend setting up the
SPACE WALKER II using the control throws
listed at right. We have listed control throws
for both Low Rate (initial test flying/sport fly-
ing) and High Rate (aerobatic flying).
 3) When the elevator, rudder and aileron
control surfaces are centered, use a ruler and
check the amount of the control throw in each
surface. The control throws should be
measured at the widest point of each sur-
face!
2) Turnonthe radiosystem,and withthe
trim tabs on the transmitter in neutral, center
the control surfaces by making adjustments
totheclevisesoradjustableservoconnectors.
The servo arms should be centered also.

FLIGHT PREPARATION.
 A) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
 B) Plug in your radio system per the
manufacturer's instructions and turn every-
thingon.
 D) Check the rudder. Looking from be-
hindtheairplane, move therudderstick to the
right. Theruddershouldmoveto theright. If it
does not, flip the servo reversing switch on
your transmitter to change the direction.
 C) Check the elevator first. Pull back on
theelevatorstick. The elevatorhalvesshould
move up. If it they do not, flip the servo re-
versing switch on your transmitter to change
the direction.
 4) By moving the position of the adjust-
able control horn out from the control surface,
you will decrease the amount of throw of that
control surface. Moving the adjustable con-
trol horn toward the control surface will in-
crease the amount of throw.
PREFLIGHT CHECK.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
2) Check every bolt and every glue joint
in the SPACE WALKER II to ensure that ev-
erything is tight and well bonded.
3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
4) Checkthecontrol surfaces. Allshould
move in the correct direction and not bind in
any way.
5) If your radio transmitter is equipped
withdualrate switchesdoublecheck thatthey
are on the low rate setting for your first few
flights.
6) Check to ensure the control surfaces
are moving the proper amount for both low
and high rate settings.
8) Properlybalancethe propeller. An out
of balance propeller will cause excessive vi-
bration which could lead to engine and/or air-
frame failure.
We wish you many safe and enjoyable
flights with your SPACE WALKER II.
7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
 E)Check thethrottle. Movingthe throttle
stick forward should open the carburetor bar-
rel. Ifit doesnot, fliptheservoreversingswitch
on your transmitter to change the direction.
 F) From behind the airplane, look at the
aileronontherightwinghalf. Movetheaileron
stickto theright. Therightaileronshouldmove
upandthe otheraileron shouldmovedown. If
it does not, flip the servo reversing switch on
