Note Regarding Hinges
Note on Lithium Polymer Batteries
For your convenience and to speed the assembly process,
the hinges have already been installed and glued. We
suggest that you take a minute before beginning assembly
of your model to check them.
Grasp the wing and aileron at each hinge location, then
gently pull on the aileron to ensure the hinges are secure
and cannot easily be pulled away from either surface.
Use caution when gripping the wing and aileron to avoid
crushing or damaging the structure. Repeat this process for
the elevator and rudder.
If, however, you find that the hinges pull away, simply
wick thin CA into the hinge slots and reinstall the
hinges/surfaces.
Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/Ni-MH
batteries used in RC applications. All
manufacturer’s instructions and warnings
must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always follow
the manufacturer’s instructions when disposing
of Lithium Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following all
instructions included with your radio.
Keep loose items that can get entangled in the propeller
away from the prop, including loose clothing, or other
objects such as pencils and screwdrivers. Especially keep
your hands away from the propeller.

when using 3-cell Li-Po packs, or 6V cutoff when using
2-cell Li-Po packs.
15
Important Information About Your Propeller
It is also very important to check to be sure the
propeller is balanced before installing onto the shaft. An
unbalanced propeller may strip the gears or cause poor
flight characteristics.
1. Solder any connectors to the speed control
to connect to the motor battery and motor if
necessary. Connect the ESC to the motor and
secure it to the inside of the fuselage using hook
and loop material. Actual ESC location may vary.
16
2. Connect the speed control to the radio system
and motor battery. Check that the motor is
rotating in the correct direction. It will rotate
counterclockwise when viewed from the front of
the aircraft. Use the instructions with your speed
control to correct a motor that is operating in the
wrong direction.
3. Tape small pieces of cardstock to the fuselage to
indicate the locations of the cowl mounting tabs
at the front of the fuselage.
4. Slide the cowling onto the fuselage. Install the
propeller adapter onto the Outrunner shaft. You
may need to ream out the hole on your prop hub
to fit the prop adapter shaft at this point. Slide the
propeller onto the prop adapter shaft. The spinner
backplate and spacers may need to be enlarged
as well to fit the prop adapter. Slide the spinner
backplate and any needed spacers onto the prop
adapter shaft. Secure the propeller using the prop
adapter spinner and be sure it is secure and tight.
17
Note: Make sure to check the balance of
the propeller after enlarging the hole in the
propeller.
5. Position the cowl so it is around 1/16"–1/8"
(1.5mm–3mm) from the spinner backplate. Use
the cardstock to drill four 1/16" (1.5mm) holes
through the cowl into the cowl mounting tabs in
the fuselage.
6. Enlarge the holes in the cowl using a 5/64"
(2mm) drill bit. Secure the cowl using four
2mm x 8mm sheet metal screws. Snap the
spinner cone onto the spinner backplate once
the cowl is secure.
Hint: Use thin CA to harden the holes drilled
into the cowl mounting tabs. This will help to
prevent the screws from vibrating loose in flight.

of the fuselage using hook and loop material.
Route the antenna wire through the bottom of the
fuselage to the rear, or as directed by your radio
instruction manual.
Note: Do not cut or change the length of the
antenna wire, as this will reduce the range of
your radio system.
26
2. Place the canopy into position on the fuselage.
Use a felt-tipped pen to trace the outline of the
canopy onto the fuselage.
3. Use medium grit sandpaper to roughen the
covering 1/8" (3mm) inside the line drawn. Also
roughen the outside 1/8" (3mm) of the canopy.
Clean the sanded areas using a paper towel and
rubbing alcohol.
27
4. Use Formula 560 canopy glue to glue the canopy
to the fuselage. Use masking tape to hold the
canopy in position until the glue fully cures.
5. Plug the Y-harness for the aileron servos into
the receiver. Attach the wing to the fuselage
using two 4-40 x 1" socket head screws and
two #4 washers.

Range Testing the Radio
1. Be sure to range check your radio before each
flying session. This is accomplished by turning
on your transmitter with the antenna collapsed.
Turn on the receiver in your airplane. With
your airplane on the ground and the engine
running, you should be able to walk 30 paces
(approximately 100 feet) away from your
airplane and still have complete control of all
functions. If not, don’t attempt to fly! Have your
radio equipment checked out by the manufacturer.
2. Double-check that all controls (aileron, elevator,
rudder and throttle) move in the correct direction.
3. Be sure that your transmitter batteries are
fully charged, per the instructions included
with your radio.
Center of Gravity
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for the
Mini Pulse XT is 2
the upper wing against the fuselage. After the first flights,
the throws can be adjusted for your personal preference.

Preflight
Check Your Radio
Before going to the field, be sure that your batteries are
fully charged per the instructions included with your radio.
Charge both the transmitter and receiver pack for your
airplane. Use the recommended charger supplied with
your particular radio system, following the instructions
provided with the radio. In most cases, the radio should be
charged the night before going out flying.
Before each flying session, be sure to range check
your radio. See your radio manual for the recommended
range and instructions for your radio system. Each
radio manufacturer specifies different procedures for their
radio systems. Next, start the motor. With the
model securely anchored, check the range again. The
range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment
checked out by the manufacturer.
Note: Keep loose items that can get entangled
in the propeller away from the prop. These
include loose clothing, or other objects such as
pencils and screwdrivers. Especially keep your
hands away from the propeller.
Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
Check the radio installation and make sure all the
control surfaces are moving correctly (i.e. the correct
direction and with the recommended throws). Test run
the motor and make sure it transitions smoothly from
off to full throttle and back. Also ensure the engine is
installed according to the manufacturer’s instructions,
and it will operate consistently.
Check all the control horns, servo horns, and clevises to
make sure they are secure and in good condition. Replace
any items that would be considered questionable. Failure
of any of these components in flight would mean the loss
of your aircraft.

fly my models in a careless, reckless and/or dangerous
manner.
4) The maximum takeoff weight of a model is 55 pounds,
except models flown under Experimental Aircraft rules.
5) I will not fly my model unless it is identified with my
name and address or AMA number on or in the model.
(This does not apply to models while being flown indoors.)
6) I will not operate models with metal-bladed propellers
or with gaseous boosts, in which gases other than air
enter their internal combustion engine(s); nor will I operate
models with extremely hazardous fuels such as those
containing tetranitromethane or hydrazine.
RADIO CONTROL
1) I will have completed a successful radio equipment
ground range check before the first flight of a new or
repaired model.
2) I will not fly my model aircraft in the presence of
spectators until I become a qualified flier, unless assisted
by an experienced helper.
3) At all flying sites a straight or curved line(s) must be
established in front of which all flying takes place with the
other side for spectators. Only personnel involved with
flying the aircraft are allowed at or in front of the flight
line. Intentional flying behind the flight line is prohibited.

2006 Official AMA National Model Aircraft Safety Code
4) I will operate my model using only radio control
frequencies currently allowed by the Federal
Communications Commission. (Only properly licensed
Amateurs are authorized to operate equipment on
Amateur Band frequencies.)
5) Flying sites separated by three miles or more are
considered safe from site-to-site interference, even when
both sites use the same frequencies. Any circumstances
under three miles separation require a frequency
management arrangement, which may be either an
allocation of specific frequencies for each site or testing to
determine that freedom from interference exists. Allocation
plans or interference test reports shall be signed by the
parties involved and provided to AMA Headquarters.
Documents of agreement and reports may exist between
(1) two or more AMA Chartered Clubs, (2) AMA clubs
and individual AMA members not associated with AMA
Clubs, or (3) two or more individual AMA members.
6) For Combat, distance between combat engagement
line and spectator line will be 500 feet per cubic inch of
engine displacement. (Example: .40 engine = 200 feet.);
electric motors will be based on equivalent combustion
engine size. Additional safety requirements will be per the
RC Combat section of the current Competition Regulations.
7) At air shows or model flying demonstrations, a single
straight line must be established, one side of which is for
flying, with the other side for spectators.
8) With the exception of events flown under AMA
Competition rules, after launch, except for pilots or helpers
being used, no powered model may be flown closer than
25 feet to any person.
9) Under no circumstances may a pilot or other person
touch a powered model in flight.
