Insert the plastic tab at the aft end of the wing into the fuselage as shown, ensuring that the wires are inside the fuselage and do not interfere with the other servos.

Press the wing into position and use the screw you removed from the wing hold down bracket to secure the wing in place. Do not over tighten the screw.

Insert the landing gear into the slot behind the battery compartment. Be sure the gear is pressed into the slot completely.

Press the propeller onto the propeller base attached to the motor shaft. Press fi rmly until it clicks into place. If the propeller does not snap easily onto the propeller base, rotate the propeller slightly and try again.

Reconfi gure the Mode of the Transmitter

Unless you are fl ying in a country where Mode 1 is prevalent, there is no reason to change the mode. If you have decided to operate your airplane in Mode 1, perform the following procedure to reconfi gure the transmitter.

Use a #1 screwdriver to loosen the antenna mounting screws.

Rotate the antenna upward until it is vertical.

Rotate the antenna 180°, allowing it to be folded down the other way.

Fold the antenna back down into the other side. Tighten the mounting screws.

Now your transmitter has been reconfi gured to operate in Mode 1 and you will be holding the transmitter 180°

(seemingly upside down) from when it was set up in

Mode 2. The control sticks will operate the airplane accordingly. The rest of the instructions illustrate the transmitter confi gured in Mode 2.

Set Up the Transmitter

With the power switch on the transmitter turned on, press the trim buttons as necessary to center the trim indicators in the status display.

Trim Indicators

Select the desired skill mode by pressing inward onto the elevator/aileron control stick. If this is your fi rst time fl ying the Extra 300, select the Low Rate mode. This will provide reduced control throws to lessen the chance of over-control for your fi rst fl ights. As you become profi cient fl ying the Extra, experiment with the high rate setting at a safe altitude.

Low Rate

Be certain the transmitter antenna is in its vertical position and that the power switch on the transmitter has been turned on. Note: Unless performing the “Binding” procedure described on page 9, never allow the battery to be connected to the Extra without the transmitter turned on. This means you should always turn on the transmitter fi rst before installing the battery into the model, and always turn off the transmitter fi rst before removing the battery from the Extra 300.

C O X M O D E L S

Also be certain the throttle control stick is fully down so the propeller will not rotate when you connect the battery. Note: If you inadvertently connect the battery with the transmitter off , or with the transmitter on but the throttle stick not all the way down, the propeller should not turn until you turn on the transmitter or move the throttle stick all the way down.

Bind The Airplane To The Transmitter

When the receiver is able to read signals from the transmitter, the two are said to be “bound.” Until the receiver in the airplane is programmed to read the transmitter’s signals, the airplane cannot be controlled. Follow the procedure below to bind the receiver to the transmitter:

1. Disconnect the LiPo battery from the airplane.

2. Turn on the transmitter. Lower the throttle control stick all the way down. Adjust the throttle trim tab until the throttle trim indicator is centered and the throttle position indicator reads “000.”

4. Connect the LiPo battery to the airplane. Turn on the transmitter while pressing inward on the throttle control stick until you hear the servos activate. If you have the wing off , you will also see the red LED on the receiver illuminate. This indicates that the receiver is reading signals from the transmitter—this should happen within a few seconds.

If it doesn’t work the fi rst time, disconnect the LiPo battery from the airplane and turn off the transmitter. Repeat the binding procedure again by reconnecting the LiPo battery and turning on the transmitter with the throttle stick depressed.

The receiver is now “bound” to the transmitter and the plane is ready to fl y.

First Flight

Turn the transmitter power switch to the ON position.

Rotate the battery door clip until it points to the aft end of the plane.

Connect the battery to the plane and insert the battery into the battery compartment. The motor is now considered live. Keep clear of the propeller in case of accidental start-up.

C O X M O D E L S

Check the Control Directions

Test the control surfaces to become familiar with their operation.

Point the propeller away from you when doing this in case of accidental start-up.

When the right control stick is moved down, the elevator will move up.

When the right control stick is moved to the left, the left aileron will move up and the right aileron will move down.

When the left control stick is moved to the left, the rudder will move to the left.

When the left control stick is in the down position, the propeller will not rotate. To test the operation of the motor, be sure to have a fi rm grasp of the airplane with your hands clear of the rotational arc of the propeller.

Be sure to point the propeller away from people or obstructions.

Trim

1. Before making your fi rst fl ight, use the trim buttons to center the elevator, ailerons, and rudder. Adjust the trim as necessary using the trim buttons until the control surfaces are inline as shown.

The ailerons can be adjusted in the same manner by disconnecting the ball links. When setting up the trims for the fi rst fl ight, be sure that you will have trim movement available in both directions so you can make fi ne adjustments during the fl ight.

Do not make your fi rst fl ight with any of the trim buttons set at their maximum position. Mechanically trim the control surfaces as necessary if this is the case.

2. If additional trim is required beyond what the trim buttons are capable of, the clevises can be disconnected from the control horns and threaded forward or aft on the pushrods. This will allow the control surfaces to be centered with the trim buttons at or near the center position.

Choose a Good Flying Site

The Extra 300 should be fl own outside only when the wind speed is

5 mph [8km/h] or less. If the wind is calm or very light, the Extra will be responsive and precise. Also, fi nd an area clear of trees, power lines and other structures. A fl ying fi eld for R/C planes is best. Don’t fl y around groups of people, especially children. Flying indoors, such as in a gymnasium, is possible but only recommended for

Prepare for Takeoff

1. Find an open area free of buildings, trees, power lines and people.

2. For your fi rst few fl ights, fl y only when the wind is calm. After you are comfortable with the airplane, you can fl y in winds that are no more than 5 miles per hour [8km/h]. If fl own in stronger blown downwind and not have enough power to get back.

3. Make sure the battery pack is fully charged and that the transmitter has fresh “AA” batteries installed.

Flight

Although the Extra is small, it will provide the same level of control and thus require the same amount of skill as a comparable larger

R/C model. Because of this, typical takeoff , fl ight, and landing routines for larger models should also be practiced with the Extra.

Takeoff

Remember to takeoff into the wind. When you’re ready, point the model straight into the wind, hold a bit of up elevator to keep the tail on the ground to maintain tail wheel steering, then gradually advance the throttle. As the model gains speed decrease up elevator allowing the tail to come off the ground. One of the most important things to remember with a tail dragger is to always be ready to apply right rudder to counteract motor torque. Gain as much speed as your fl ying site will practically allow before gently applying up elevator, lifting the model into the air. At this moment it is likely that you will need to apply more right rudder to counteract motor torque.

Be smooth on the elevator stick, allowing the model to establish a gentle climb to a safe altitude before making your fi rst turn.

14 E X T R A 3 0 0

Flight

Take it easy with the Extra for the fi rst few fl ights, gradually getting acquainted with it as you gain confi dence. Adjust the trims to maintain straight and level fl ight. After fl ying around for a while, and while still at a safe altitude with plenty remaining battery charge, practice slow fl ight and execute practice landing approaches by reducing the throttle to see how the model handles at slower speeds.

Add power to see how she climbs as well. Mind your battery charge, but use this fi rst fl ight to become familiar with your model before landing. Typical fl ight time will be approximately 6 to 8 minutes.

Landing

To initiate a landing approach, lower the throttle while on the downwind leg. Allow the nose of the model to pitch downward slightly as you begin to gradually bleed off altitude. Continue to lose altitude, but maintain airspeed by keeping the nose down as you turn onto the crosswind leg. Make your fi nal turn toward the landing site (into the wind) keeping the nose down to maintain airspeed and control. Level the attitude when the model reaches the runway threshold, modulating the throttle as necessary to maintain your glide path and airspeed. If you are going to overshoot, smoothly advance the throttle (always ready on the right rudder to counteract torque) and climb out to make another attempt. When you’re ready to make your landing and the model is about a foot or so off the ground, smoothly increase up elevator until it gently touches down. Once the model is on the ground and has lost fl ying speed, hold up elevator to place the tail on the ground, regaining tail wheel control.

CAUTION: If, during a rough landing, the propeller on the Extra should become jammed and cannot rotate with the throttle in the run position, the battery and airplane electronics could become damaged. Immediately lower the throttle to stop the motor.

After the Flight

Disconnect and remove the battery from the airplane. Then, switch the transmitter off . Allow the battery to cool before recharging.

Check the airplane over to make sure nothing has come loose or may be damaged.

Repairs

Even the best R/C pilots in the world damage their airplanes every now and then. In the unfortunate event that you damage your airplane, repairs are fairly simple to make yourself. If there are any cracks in the wing or fuselage, apply 6-minute epoxy, white glue, or CA glue to the broken areas and hold them together with clear packaging tape. Let the glue harden, then carefully remove the tape.
