Introduction

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® and UltraCote Lite covering, steerable tail wheel, 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.

Required Radio Equipment

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™ DX6i 2.4GHz DSM® 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 DSM2™ 6-channel receiver and four of our Spektrum 7.5-gram Super Sub-Micro Digital Programmable Servos.

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.

	Hinging the Ailerons
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.

mmm 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.

mmm 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.

mmm 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.

mmm 5. Make sure the aileron does not bind at the center of the wing.

mmm 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.

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.

mmm 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.

m 8. Repeat Steps 2 through 7 for the remaining aileron on the bottom wing.

E-flite Ultimate 20-300 Assembly Manual

9. Repeat Steps 2 through 8 to attach the aileron to the top wing. You should now be done with the aileron installation.

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 Installation

Required Parts
Top wing	Bottom wing
Control horn (2)	Interconnect horn (4)
Aileron servo (2)	Silicone clevis retainer (2)
Nylon connector backplate (2)	Machine screw, 2mm x 4mm (2)
6-inch (152mm) servo extension (2)
Lightweight screw lock connector (2)
Servo linkage, 2.5-inch (62mm) (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

mmm 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.

E-flite Ultimate 20-300 Assembly Manual

mmm 2. Use a hobby knife to trim the covering from the 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.

Align horn to aileron centerline

m 3. Repeat Step 2 for the top aileron at this time.

E-flite Ultimate 20-300 Assembly Manual

m 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.

m 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.

m 6. Use the string to pull the extension through the hole at the center of the bottom wing.

Hint: Use low-tack tape to keep the ailerons from moving during the servo installation.

m 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.

m 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.
