Introduction
Thank you for purchasing the Ultra Stick 25e. Designed
from the beginning for electric power, the Ultra Stick 25e
is developed from the popular Hangar 9®Ultra Stick™
series of aircraft. You will find most all of the hard work
completed for you. All flight control surfaces, control
horns, wheels, and other necessary items required to
speed up the building time have been installed at the
factory. You will find two sets of mounting holes on the
firewall to mount your choice of either the Power 25
or 32 Outrunner motors. An additional aluminum float
mount is included if you wish to fly with the optional
25-size Fiberglass floats (EFLA500A). The Power 32 is
recommended if you wish to fly with the floats. This is to
help maintain the CG required for flight. If you wish to
use the Quad Flap option you will need to use a receiver
battery to power the radio as the BEC unit in most speed
controls can only power 4 servos. All necessary control
linkage hardware is included for the Quad Flap option if
you choose to install it.
Specifications
Wingspan: 50 in (127cm)
Length: 41.5 in (105cm)
Wing Area: 480 sq in (31 sq dm)
Weight w/o Battery: 2.6 lb (1.2 kg)
Weight w/ Battery: 3.4 lb (1.5 kg)
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.

Required Radio Equipment
You will need a minimum 4-channel transmitter, crystals,
micro receiver, and four mini servos. You can choose to
purchase a complete radio system that includes all of
these items or, if you are using an existing transmitter, just
purchase the other required equipment separately.
You may wish to install the optional quad flaps, in which
case you will need a 7-channel radio and receiver on
72MHz with mixing and six mini servos.

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.

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.

Safety, Precautions, and Warnings
11

1. Locate the landing gear assembly. Attach the
landing gear assembly to the fuselage using
three 4-40 x 1/2" socket head screws.
Note: The landing gear will only fit one
direction for the holes to line up properly.
Landing Gear Installation
Required Parts
• Fuselage
• Landing gear assembly with wheels
• 4-40 x 1/2" socket head screw (3)
Required Tools
• Hex wrench: 3/32"
12

Motor Installation
Required Parts
• Fuselage
• Brushless motor
• Brushless speed control
• 4-40 x 3/8" socket head screw (4)
• Prop adapter
• Propeller
• 4-40 blind nut (4)
Required Tools and Adhesives
• Hex wrench: 3/32"
Note: There are two sets of holes in the
firewall. The outer set of holes is used to mount
the Power 32 motor, while the inner holes are
used for mounting the Power 25 motor. Use the
appropriate holes for your motor.
1. It may be necessary to attach the motor mount
or other accessories to your particular motor at
this time.
13

2. Place the four 4-40 blind nuts on the inside of
the firewall in the locations for your particular
motor. Attach the Outrunner motor to the front
of the firewall using four 4-40 x 3/8" socket
head screws.
14

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, and 12V cutoff when using 4-cell
Li-Po packs.
3. 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.
Note: It is wise to place a current meter in line
with the ESC to check for current draw during
full servo operation. Please see page 29 for
further details.
4. Slide the propeller adapter onto the motor. Place
the propeller onto the adapter, then a spinner
cone onto the adapter and secure.
Note: It is very important that you check to be
sure the propeller is balanced before installing
onto the shaft. An unbalanced propeller will
cause performance issues.
15

1. Slide the rudder into position on the fuselage.
The threaded rods extend through the bottom
of the fuselage.
Tail Installation
Required Parts
• Fuselage
• Rudder/Fin
• Stabilizer/Elevator
• 3mm locknut (2)
• 3mm washer (2)
Required Tools and Adhesives
• Nut driver: 1/4"
Note: Before installing the tail, check to
make sure the hinges are glued securely by
gently pulling on the two surfaces. If they are
not glued securely, apply thin CA to both
sides of the hinge to secure them. Do not
use accelerator. The CA must be allowed to
soak into the hinge to provide the best bond
between the hinge and surrounding wood.
16

2. Attach the stabilizer using two 3mm washers and
two 3mm locknuts. Do not tighten the locknuts all
the way until after the wing is installed and you
check the alignment.
Note: The tail section is removable for easy
transporting if needed.
Wing Preparation
Required Parts
• Wing
• 6-channel receiver
• Servo w/hardware (2)
• Servo extension, 6" (2)
• Clevis (2)
• Pushrod connector (2)
• 5 5/8" (143mm) pushrod wire (2)
Required Tools and Adhesives
• Drill
• Drill bit: 1/16" (1.5mm), 5/64" (2mm)
• Screwdriver, #0 Phillips
• Pliers
Note: For the optional Quad Flap modification,
please refer to information on Page 20.
Note: Check to make sure the aileron hinges
are glued securely by gently pulling on the two
surfaces. If they are not glued securely, apply
thin CA to both sides of the hinge to secure
them. Do not use accelerator. The CA must be
allowed to soak into the hinge to provide the
best bond between the hinge and surrounding
wood.
17

1. Install the aileron servo into the wing.
The servo lead will exit the hole in the bottom
center of the wing. Drill a 1/16" (1.5mm) hole
through each brass eyelet into the servo mount.
Be careful not to drill through the covering in the
top of the wing.
2. Secure the servo using the hardware that was
provided with the servo.
18

3. Attach the clevis to the 5 5/8" (143mm)
pushrod wire. Thread the clevis onto the pushrod
wire at least 12 turns.
4. Attach the clevis to the control horn. Plug the
aileron servo into the receiver and turn on the
radio. Center the aileron servo electronically. Use
a felt-tipped pen to mark the pushrod wire where
it crosses the servo horn.
Hint: Use painter’s tape to tape the aileron
to the wing tip. This will hold the aileron in
the centered position while you prepare the
pushrod wire.
19

5. Bend the pushrod wire 90 degrees at the
mark made in the last step. Enlarge the outer hole
of the servo arm using a 5/64" (2mm) drill bit.
Slide the wire through the servo arm. Secure the
pushrod wire using a pushrod connector.
Note: Use side cutters to trim down the excess
pushrod wire and remove the extra arms from
the servo horn.
6. Repeat Steps 1 through 5 for the remaining
aileron linkage installation.
