Introduction
Thank you for purchasing the Mini Pulse XT. Designed
from the beginning for electric power, the Mini Pulse XT
is developed from the Hangar 9®Pulse™ XT with the
same flight characteristics as the 40-size version. It is a
perfect transitional airplane for beginners who want to
learn aerobatics and for sport flyers who want an easy,
comfortable sport flyer. All flight control surfaces, hinges,
and control horns have been installed at the factory to
help speed up the building time.
Specifications
Wingspan: 42.5 in (1080mm)
Length: 37.5 in (875mm)
Wing Area: 330 sq in (21.5 sq dm)
Weight w/o Battery: 21–22 oz (710–820 g)
Weight w/ Battery: 25–27 oz (795–965 g)
Using the Manual
This manual is divided into sections to help make assembly
easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed
next to each step to keep track of each step completed.
Steps with a single circle () are performed once, while
steps with two circles () indicate that the step will
require repeating, such as for a right or left wing panel,
two servos, etc.
Remember to take your time and follow the directions.

Note Regarding Hinges
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.
Note on Lithium Polymer Batteries
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.

1. Place the landing gear onto the bottom of
the fuselage. They will angle back slightly when
installed in the correct direction. Attach with
two 4-40 x 1/2" socket head bolts and two #4
black washers.

Nut driver: 1/4"
Needle-nose pliers
Note: You may consider using a larger
diameter wheel, such as 2 1/4" (58mm), if
your flying site has rough terrain. By using a
larger wheel, you will not be able to use the
included wheel pants.
12

2. Slide the 4-40 x 1 1/4" socket head bolt
through one of the 2" wheels. Slide a #4 steel
washer so it fits against the wheel. Next secure
a 4-40 nut against the washer. Make sure the
wheel still spins freely. Slide a second #4 steel
washer onto the bolt. This washer will fit inside
the wheel pant.
3. Fit the assembly in Step 2 into the wheel pant
and insert the bolt into the landing gear. With
the fuselage level to the work surface, rotate the
wheel pant so it is also level to your work surface
and secure the pant to the landing gear with a
2mm x 6mm wood screw. Secure the bolt with
a 4-40 locknut while using needle-nose pliers to
hold the head of the bolt inside the pant.
3. Repeat Steps 2 and 3 for the remaining wheel
and wheel pant.

the recommended Park 450 Outrunner motor.
The holes in the firewall for mounting the
custom X-mount will also fit the hole pattern for
our E-flite® Firewall Stick Mount (EFLM1916
– available separately) if you prefer to use a
gearbox with an inrunner motor.
1. Attach the supplied aluminum motor X-mount
to the motor using the screws provided with the
motor. The wider section of the mount will be
positioned towards the motor wires.
14

2. Attach the Outrunner motor to the front of the

Important Information About Your Brushless ESC
Make sure your ESC brake is programmed to Off.
Also, be sure to use an ESC with the proper 9V cutoff
when using 3-cell Li-Po packs, or 6V cutoff when using
2-cell Li-Po packs.
15

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.
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.
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.

threaded rods from the rudder/fin assembly will
slide into the two holes in the stabilizer.
3. Slide the rudder/stabilizer assembly onto the
fuselage. Slide the #4 washers onto the threaded
rods. Thread the nuts onto the rod, tightening
them snugly against the bottom of the fuselage.
