E-flite's Ultimate 20-300 10 ARF is a sport replica of the
rare two-place aerobatic aircraft. The large wing area and
light wing loading of its biplane design provide smooth flight
characteristics and precise response. The Ultimate is designed
around E-flite's Power 10, which provides excellent power
for any aerobatic maneuver. The Ultimate's features include:
UltraCote
authentic Ultimate style spinner, fiberglass cowl and wheel
pants, plastic molded wing fillets, and a lightweight balsa and
plywood frame. The features and level of prefabrication of
the Ultimate allows the modelers to have the ability to fly this
incredible biplane in less time than similar models.
Intermediate pilots will enjoy the ability to grow their skills
rapidly with the Ultimate, while advanced pilots will enjoy
maximum performance with no extra effort.

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.

You will need a minimum 5-channel transmitter, receiver, and four
sub-micro servos. You can choose to purchase a complete radio
system. If you are using an existing transmitter, just purchase
the other required equipment separately. We recommend the
crystal-free, interference-free Spektrum
6-channel system. If using your own transmitter, we recommend
the Spektrum 7.5-gram Super Sub-Micro Digital Programmable
Servos. When using the Spectrum DS75 servos with the Ultimate
20-300 you must use the Spectrum Digital Servo Programmer
(SPMDSP). This will allow you to get the proper travel, resolution
and geometry.
If you own the Spektrum DX6i radio, just add the AR6200

Notes Regarding Servos and ESC
WARNING: Use of servos other than those we suggest may
overload the BEC of the recommended Electronic Speed Control
(ESC). Please use only the servos listed when utilizing the
recommended ESC’s BEC, or the use of a separate BEC (like the
UBEC) or receiver battery pack when using other servos.
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.

Safety, Precautions, and Warnings
Hinging the Ailerons
As the user of this product, you are solely responsible for
operating it in a manner that does not endanger yourself
and others or result in damage to the product or the property
of others.
Carefully follow the directions and warnings for this and any
optional support equipment (chargers, rechargeable battery
packs, etc.) that you use.
This model is controlled by a radio signal that is subject to
interference from many sources outside your control. This
interference can cause momentary loss of control so it is
necessary to always keep a safe distance in all directions around
your model, as this margin will help to avoid collisions or injury.
• Always operate your model in an open area away from cars,
traffic or people.
• Avoid operating your model in the street where injury or
damage can occur.
• Never operate the model out into the street or populated areas
for any reason.
Required Parts
Top wing Top ailerons (right and left)
Bottom wing Bottom ailerons (right and left)
CA hinge (16)
Required Tools and Adhesives
Felt-tipped pen Straight edge/ruler
Hobby knife Thin CA
Scissors
1. Use scissors or a hobby knife to cut each hinge away
from the others.
2. Use a felt-tipped pen to mark the center of four
CA hinges. This will help in positioning them equally
in the aileron and wing.
• Never operate your model with low transmitter batteries.
• Carefully follow the directions and warnings for this and any
optional support equipment (chargers, rechargeable battery
packs, etc.) that you use.
• Keep all chemicals, small parts and anything electrical out of
the reach of children.
• Moisture causes damage to electronics. Avoid water exposure
to all equipment not specifically designed and protected for
this purpose.
7E-flite Ultimate 20-300 Assembly Manual
3. Position the hinges in the pre-cut slots in the
aileron. Slide the hinges into the aileron up to the
mark made in the previous step.
5. Make sure the aileron does not bind at the center
of the wing.
4. Slide the aileron in position with the hinges
inserted in the slots of the wing. Check that the end
of the aileron is aligned with the wing tip using a
straight edge.
6. Use a hobby knife with a #11 blade to set the
gap between the aileron and wing. The blade should
barely slide between the two surfaces. Doing so will
allow achieving the control throws listed with the
smallest gap possible.
8 E-flite Ultimate 20-300 Assembly Manual
Note: If the control surface is tight against the main
surface, it will limit the amount of control throw the
surface can achieve.
7. Apply thin CA to the top and bottom of each
hinge. Make sure to saturate the hinges, applying
the CA to the slot in the hinge so it penetrates fully
into the hinge for the best bond between the aileron
and wing.
9. Repeat Steps 2 through 8 to attach the aileron to
the top wing. You should now be done with the aileron
installation.
8. Repeat Steps 2 through 7 for the remaining aileron on
the bottom wing.
10. Once the CA has fully cured, lightly pull on each
surface to make sure that each hinge has been fully
saturated with CA.

Aileron servo (2) Silicone clevis retainer (2)
Nylon connector backplate (2) Machine screw, 2mm x 4mm (2)
6-inch (152mm) servo extension (2)

Required Tools and Adhesives
Medium CA Thin CA
Side cutters Hobby knife
Low-tack tape Pin drill
Drill bit: 1/16-inch (1.5mm) Phillips screwdriver: #0, #1
Felt-tipped pen
1. Slide the control horn into the pre-drilled holes in
the aileron. Use a felt-tipped pen to mark the area
around the base of the control horn. Remove the
horn and use a hobby knife to cut the covering away
from the area inside the outline. Use side cutters to
trim 2-3mm off of the aft lug on the control horn.
This will eliminate the lug protruding through the
other side of the aileron. Use medium CA to glue the
control horn in the holes in the aileron. Make sure
the horn rests flush with the surface of the aileron.
Note: The aileron control horns do not require
back plates.
10 E-flite Ultimate 20-300 Assembly Manual
2. Use a hobby knife to trim the covering from the
Align horn to aileron centerline
slot in the aileron. Leave the covering on the top
for aesthetic purposes. Use medium CA to glue the
interconnect horn in the aileron. Make sure to center
the horn in the aileron before the CA fully cures.
4. Secure a 6-inch (152mm) servo extension to the
aileron servo so it will not unplug inside the wing.
Hint: Use a piece of string or some tape to secure the
two plugs together so that they cannot pull apart inside
the wing.
3. Repeat Step 2 for the top aileron at this time.
5. A string has been placed inside the wing to pull the
servo extension to the center of the wing. Tie this string to
the end of the servo extension as shown.
11E-flite Ultimate 20-300 Assembly Manual
6. Use the string to pull the extension through the hole at
the center of the bottom wing.
7. Position the servo in the opening. Use a pin drill and
1/16-inch (1.5mm) drill bit to drill the holes for the servo
mounting screws. Use care not to slip and puncture the
covering on the top of the wing.
Hint: Use low-tack tape to keep the ailerons from moving
during the servo installation.
8. Apply 2–3 drops of thin CA into each hole to harden
the surrounding wood. This will keep the screws secure
in the holes. Install the servo using the screws provided
with the servo and a #0 Phillips screwdriver.
