TOOLS & SUPPLIES NEEDED.
!Thick cyanoacrylate glue.
!30 minute epoxy.
!5 minute epoxy.
!Hand or electric drill.
!Assorted drill bits.
!Modellingknife.
!Straight edge ruler.
!2mm ball driver.
!Phillips head screwdriver.
!220 grit sandpaper.
!90° square or builder’s triangle.
!Wire cutters.
!Masking tape & T-pins.
!Thread-lock.
!Paper towels.
!1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
!2)Removeeach hingefromthe wing panel
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
ofhingeis on eithersideof the hingelinewhen
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
shouldbe maintainedbetween the wingpanel
andaileron.
!4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurface shouldlightlycontactthe
wing during this procedure. Ideally, when the
hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the
aileron to the wing panel hinge line.
The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistribute throughoutthe
hinge, securely bonding it to the wood
structureof thewingpanel andaileron.
Note:
C/Aglue.
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethat youproperly adherethe
hingesin placeper thesteps thatfollow
using a high-quality thin C/A glue.
Note:

HINGING THE RUDDER.
!7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
!5)Turnthe wingpanelover anddeflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsurethattheC/Apenetratesinto
both the aileron and wing panel.
!6) Using C/A remover/debonder and a
papertowel, removeanyexcess C/Aglue that
may have accumulated on the wing or in the
aileronhinge area.
HINGING THE ELEVATOR.
Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.
Note:
Glue the elevator hinges in place using the
same tectniques used to hinge the ailerons.
Glue the rudder hinges in place using the
same tectniques used to hinge the ailerons.
INSTALLING ELECTRIC MOTOR.
!8)Afterbothailerons are securely hinged,
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.
!1) Trial fit the motor on the firewall. The
motorshouldbepositioned sothereisaample
clearance in the fuselage end side for the
spinner backplate mounted to the propeller
drive shaft.
!2) Marking four points on the firewall. Drill
4 pilots horn 4.5mm diameter.
!3) Insert 4 blind nuts at the back side of
firewall. See picture below:
Insert 4 blind nuts.

!2) Insert the main gear wire into the
mounting slot .Using the hardware provided,
mount the main landing gear to the fuselage.
!3) The landing gear wire is held in place
using two nylon landing gear straps and four
3mm x 10mm wood screws.
AILERON SERVOS-LINKAGES.
! 1) Install the metal connector onto servo
arm as same as picture below.
Attach the micro control connector to the
servo arms. Be sure to use the lock tie but it
could free rotation .
! 3)Secure the servos with the screws pro-
vided with your radio system.
!2) Turn the wing panel right side up. Using
amodelingknife,removethe covering atservo
tray.
Attach the thread to the servo lead and
carefully thread it though the wing.
Install the rubber grommets and brass collets
onto the aileron servo. Test fit the servo into
the aileron servo mount.

INITIAL FLYING/SPORT FLYING
Ailerons: 3/8” up 3/8” down
Elevator: 3/8 ” up 3/8” down
Rudder: 1/2” right 1/2” left
AEROBATIC FLYING
Ailerons: 1/2”up 1/2”down
Elevator: 5/8”up 5/8”down
Rudder: 1” right 1”left
Do not use the aerobatic settings for
initial test flying or sport flying.
! 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.
!1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
yourplane to losecontrol and crash. Thecen-
ter of gravity is locate 5.5-6.5cm back from
theleadingedgeofthewing,measuredatwing
tip.
BALANCING.
!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, move thebattery 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.
!1) We highly recommend setting up the
INNOVATOR. using the control throws listed at
right. We have listed control throws for both
Low Rate (initial test flying/sport flying) and
High Rate (aerobatic flying).
CONTROL THROWS.
! 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) Turnon theradio system,and withthe
trim tabs on the transmitter in neutral, center
the control surfaces by making adjustments
totheclevises oradjustableservo connectors.
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.
! E)Check the throttle.
! D) Check the rudder. Looking from be-
hindthe airplane, movethe rudderstick to the
right. Therudder should moveto the right. Ifit
does not, flip the servo reversing switch on
your transmitter to change the direction.
! C) Check the elevator first. Pull back on
theelevator stick. Theelevator halvesshould
move up. If it they do not, flip the servo re-
versing switch on your transmitter to change
the direction.
! F)From behind the airplane, look at the
ailerononthe rightwinghalf. Movethe aileron
sticktotheright. Therightaileronshouldmove
upand theotheraileron shouldmovedown. If
it does not, flip the servo reversing switch on
your transmitter to change the direction.
!5) If your radio transmitter is equipped
withdual rateswitches double checkthat they
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) Properlybalance thepropeller. 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 INNOVATOR.
!7) Check the receiver antenna. It should
be fully extended and not coiled up inside the
fuselage.
PREFLIGHT CHECK.
!1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
!2) Check every bolt and every glue joint
inthe INNOVATOR toensure thateverything is
tight and well bonded.
!3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
!4) Checkthe controlsurfaces. All should
move in the correct direction and not bind in
any way.
