installed. See page 18.
oam is a unique matrix that is
resistant to solvents. The urethane paint
however is not. Repairs can be made
with Zagi-Lock and clear tape. Avoid
overflowing the glue onto the painted
surfaces. Isopropyl alcohol (rubbing
alcohol) or Windex can be used safely to
remove residual mold release before
applying tape or decals. Place the decals
carefully the first time. The decal
adhesive will lift the paint.
NiCad and NiMH batteries are not
shipped with a charge. All batteries must
be charged before any hookup can be
done. Charge the TX (transmitter) battery
over night with the charger in the radio
component box. The radio component
charger will not charge the 8 cell 370
mAh NIMH battery. It must be charged
with a separate charger. Make sure that
the charger is designed to charge a 9.6v
8 cell MiMH battery.
Use the decal stars sparingly
sparingly.. Since
most decals and other design decorations are applied behind the center of
gravity, the wing can become tailheavy.
The decals are better used for repairs.
(See page 21)
Pusher motors don’t have the advantage of the prop wash for cooling.
Pushers instead depend on the air
resulting from the forward motion of the
aircraft. A heat sync employs heat
conducting aluminum fins to help the
motor case dissipate heat by increasing
the surface area. Lowering the operating
temperature can extend the life of the
motor. The heat sync was manufactured
to close tolarances and must be installed
correctly to conduct properly.

The servo bay of the Zagi FiXX was
designed to fit the Hitec HS-55
servo. The HS-55 is a moderately
priced readily available servo with
more than adequate torque.
Clip both of the mount tabs off of
the servos
Find the control arm with small
holes in the parts bag supplied with
the servo.
Remove the servo control arm with
the large holes.
Cut one of the arms off of the
control arm with the small holes
The trim levers are located on the
transmitter to the left and below the
control stick. Some trim controls are
electronic and others are mechanical. Trim levers are provided to
adjust the zero position of the
servos. Center the trim levers. The
control surfaces of the Zagi FiXX are
called elevons because they combine the functions of the elevator
and aileron by means of an electronic mixer.
Computer radios have settings for
elevon mixing. Check the radio
manual for flying wing, elevon or
delta mix setting. V-tail settings will
not work. Once the transmitter is set
for elevons, determine the appropriate receiver slot for the controls. Lay
the servos the way they will be in the
wings. Plug the right and left servos
into the receiver.

motor in at this time.
When the stick is pulled back (the
opposite direction to antenna) the
servo control arms should move
forward. When the stick is moved to
the right, the right servo control arm
should move forward and the left
servo control arm moves back.
The control arm should be at 90
degrees to the servo in the hands off

Hold the tape securely and pull it
until it curves to the shape of the
skid. Pull and lower the curved tape
onto the full length of the skid. Press
the tape to the contour of the skid.
The vinyl tape is important to create
an armor film for landing.
The antenna groove is located on the
right panel. It extends from the center
pod all the way to the tip. At the pod
end of the antenna groove, spin a
1/8” drill bit or a pointed tool to
make a hole. Aim the drill at an
angle to come out in the corner of
the receiver bay. Spin the drill
through to the receiver bay.
Clear the antenna hole from the top
side. Push the antenna wire through
the hole from the top to the bottom
Pull only enough antenna wire
through the hole to extend to the tip
of the wing. Extend the wire to the tip
along the groove. Hold it in place
with small pieces of Scotch tape six
inches apart.
Do not cut the extra antenna wire!
Some radio manufacturers provide a
small fixture to spool the extra
antenna wire. If this is not the case,
locate the popcicle stick in the parts
bag. Cut a 1-1/2 inch piece from the
stick. Check that the stick fits good
and tight across the aft end of the
receiver bay.
Spool the antenna wire around the
popcicle stick. Make an even spiral
wrap around the stick being careful
not to overlap. Hold the antenna
wire in place with a piece of tape.
Push the extra antenna spool across
the aft end of the receiver bay.
Check the fit of the receiver under the
canopy when installed on its side.
Locate the Velcro squares in the
hardware bag. Separate the hook from
the loop sides. Peel the backing from
the hook sides. Squeeze a zigzag bead
of Zagi-Lock CA on the glue side of the
Velcro. Glue one in the receiver bay
and one in the forward most end the
battery bay.
Do not use glue on the receiver or the
battery. Stick one of the Velcro loop side
squares on the battery opposite the
label. Stick one of the Velcro loop side
squares on the receiver. If the receiver
fits under the canopy on its side, put the
Velcro on the side.

Locate one of the two 14 1/2 X 3/
4” clear armor strips on the decal
sheet. These strips are provided as
crash armor for severe head-on
crashes. In the event of such a
crash the strips help to prevent the
trailingedge of the wing from
cracking or separating. Cut one of
the strips into two equal pieces 7 1/
4” long.
The clear decal armor strip works
best when applied parallel to the
trailing edge at the prop cutout.
Wipe the area with alcohol or
windex. Slip the decal under the
control arm. Align the decal
parallel to the trailind edge and
press the square end to the base of
the motor pylon. Press the remaining length to the wing. Do not try to
follow the elevon hinge line.
Measure and mark the center of the
remaining armor strip on the decal
sheet. Center the center line mark
with the center of the wing. Align
the armor strip with the trailing edge
of the prop cutout between the

bubbles can be trapped under the
armor strip. Do not try to remove
the armor strip. Poke the bubble
with a pin and chase the air bubble
out through the vent.
Remove one nut and both washers.
Slide the prop onto the shaft with
the raised letters toward the motor
Make sure that the nut mates with
the nut-shaped cutout in the prop.
Use the prop as a wrench to
unscrew the nut to the end of the
shaft. Leave 1/8 of an inch for the
two washers and the nut. Slide the
two washers against the prop. Turn
the nut on the shaft. Hold the large
gear and the prop to snug the shaft
Insert the motor wire into the motor
wire hole in the motor pylon. Pull the
wire from the receiver bay side while
pushing the motor onto the motor
mount stick.
Push the motor all the way onto the
motor mount stick until it seats.
Plug the motor wire into the ESC.
The polarity to the motor should be
reversed so that the motor will work
as a pusher. It is easy to see the red
side of the motor plug being
plugged into the black side of the
ESC wire. DO NO
See pages 18 for first time power-up
Plug the right and left servos into the
Receiver. Plug the ESC radio wire
into the receiver. Roll the ESC wires
and stuff them next to the receiver.
Push the ESC on the top with the
label side down.
The ESC has no on/off switch. Use
the battery plug as the switch.
The circuit board side of the ESC
should be visible through the canopy
vent hole.
The final step is balance. The center
of gravity, (CG) is located 1/8 inch
forward (toward the nose) of the
servo wire channel.
If the airplane has been assembled
using this manual, the balance
should be correct. Make sure that
the battery is all the way forward in
the battery bay and the motor and
prop are in place. Balance the
airplane on your fingertips 1/8 of an
inch forward of the servo wire
The Zagi-FiXX will fly best with the
elevons set between zero and .03”
of up elevator.
The most common reason for
balance problems is over decorating
the wings. Use the decals sparingly.
Repairs can change the CG. Always
check the balance after repairs. A

1. Make sure that the motor is securely attached to the motor mount stick.
2. Make sure that the reverse switch for the motor control stick on the transmitter is
in the normal position. Not reversed!
3. Push the motor control stick on the transmitter to the full off position.
4. Push the motor control stick trim lever to the center position.
5. Turn the transmitter power on. Check the output meter for battery condition.
6. Secure the charged 8 cell battery in place with the Velcro tabs.
7. Check that the ESC signal lead is in the motor slot of the receiver.
8. Position yourself with the nose of the airplane pointed at you. Plug the battery
into the electronic speed control (ESC). Make sure that the polarity is reversed on
the motor side.
9. Move the motor control stick slowly upward. The motor should run faster the
further up the stick is moved. The motor should turn counter clockwise when
observed from the front.
Preflight check and glide test
Do a preflight check before every flight. Always turn the transmitter power on before
the motor battery in the airplane is plugged in. Make sure that the motor control
stick is in the full down position. Make sure that the controls are working properly.
Check the trim levers on the transmitter. Pull the control stick back and observe that
both elevons move upward. Push the control stick to the right and observe the right
elevon moves up and the left elevon moves down. Hold the Zagi-FiXX securely by
the nose. Move the throttle stick to the half throttle position momentarily. The first
glide test should be done on flat land in a light breeze. Hold the Zagi-FiXX over
your head with the nose pointed straight ahead. Run slowly into the wind. Give it a
gentle push LEVEL AND STRAIGHT AHEAD. Do not point the nose upward. Correct
the flight path with the radio control stick. The test is successful when the Zagi-FiXX
flies straight ahead with a slow sink rate to a sliding landing. If the Zagi-FiXX turns
in either direction after the launch, compensate by adding 2 or 3 clicks of trim in
the opposite direction with the trim lever below or next to the control stick. If the
Zagi-FiXX pitches up and immediately dives, add 2 or 3 clicks of down trim. Repeat
the glide test until the Zagi-FiXX flies straight ahead with a slow sink rate to a sliding
landing. Increase the launch speed each time to provide longer controlled flights.
First flight
Check the frequencies (channel number) of all pilots within visual range before
turning on your transmitter. Turning on your transmitter with the same channel
number as someone who is flying will certainly cause his plane to crash.

The Zagi-FiXX is supplied with a balanced power system. Changing the prop will
change the load on the motor ESC and the battery. The Zagi-5 ESC is rated at 5
amps continuous. The Zagi-FiXX with a 370 mAh battery and the stock prop draw
2.5 amps at full throttle. So if the prop diameter or pitch is increased, the load
could exceed the range of the 5 amp ESC. This balanced system was tested with
over a hundred flights. Changing the pitch or diameter burn out the motor after
only a few flights. Using a 1000 mAh battery will burn out the GWS motor after
only a few flights. Trial and error can get expensive. The way to choose the correct
prop for an electric airplane is with the use of a watt meter. Astro Flight makes a
“Wattmeter for indoor R/C models” for $55.00 from Trick R/C. This device will
keep the smoke from escaping from the speed control. Another useful tool is a
tachometer. Cermark makes a good tach for cheap. A simple thrust meter can be
made with a small postal scale calibrated in ounces. A test stand setup with a
wattmeter, a scale and a tach will take the guesswork out of balancing electric
Battery life is determined by two main factors; charging and discharging. Both of
these functions produce heat. Warm is okay, hot isn’t. A hot battery has either been
charged or discharged too fast. First, charging. Make sure that the charger is
designed to charge the number of cells being charged. The best type of charger is
the peak detector type. These chargers will charge the battery to peak at a preselected rate then drops to a trickle. Chargers with timers will often over charge
batteries causing excessive heat. Manufacturers recommend charging batteries at
the rated capacity i.e., a 500 mAh battery should be charged for one hour at 500
mAh. The exception to this is the batteries with the letter “R” at the end of the
designation (500AR, or 2000SCR). The “R” means rapid charge and discharge.
“R” cells are either very expensive or not available in small sizes. Hobbyists are
notorious battery abusers. Batteries that are not designed for rapid charge are
routinely over charged by charging and discharging them too fast. NiCad cells
have a finite number of cycles. Abuse will decrease the number of cycles. Electric
flight hobbyists are willing to accept the shortened life of the batteries for performance. There are ways to cut these losses. Don’t charge at a rate more than twice
the designated capacity of the battery. Don’t charge a hot battery. Get enough
batteries to fly one, cool one, and charge one. A way to speed up the cycle is to
make a 12 volt field battery cooler. Tape a 12 VDC muffin fan to a 6 inch length of
2 inch PVC pipe. The muffin fan is available at Radio Shack or find an old computer power supply fan (but make sure it’s designed for 12 VDC and not 110 VAC).
