it "click" into position.
SECTION 4: EXTRA 300 RTF FINAL ASSEMBLY

5
Step 2: Charging the Flight Battery
❑Plug the flight battery connector into the battery
charger connector. When plugged in properly the
connectors should "click" together.
☞Note that the plugs can be plugged in only one way.
❑Plug the charger into a 110V AC wall outlet.
❑Charge the flight battery for 1-1/2 to 2 hours, being
careful not to overcharge the battery.
❑To unplug the connectors, squeeze the tab on the
battery connector and pull the two connectors apart.
Step 3: Installing the Vertical Tail
Continued on Next Page
❑Insert the Z-shaped bend (Z-bend) in the rudder
pushrod wire into the middle hole in the plastic control
horn on the side of the vertical tail.
☞When installing the Z-bend, make sure the longer
portion of the wire is toward the bottom of the plastic
control horn, as shown.
❑Carefully push the vertical tail down into the plastic
mount and firmly into the molded groove in the top of the
fuselage.
❑Look at the vertical tail from the front of the fuselage.
It should be straight up and down.

6
❑Slide the plastic landing gear retainer into the slot and
push it down firmly.
❑Install and tighten the small wood screw to secure the
landing gear retainer into place.
❑To hold the vertical tail in place, thread the short wood
screw into the predrilled hole in one side of the plastic
mount, through the vertical tail, and into the predrilled hole
in the opposite side of the plastic mount.
☞Do not overtighten the screw or you might strip the
plastic mount.
Step 4: Installing the Landing Gear
❑Push the landing gear wire firmly down into the slot in
the bottom of the fuselage.

7
Step 5: Installing the Wing
❑Set the wing onto the fuselage, making sure the small
dowel in the front of the wing engages the predrilled hole
in the plastic mount at the front of the wing saddle.
❑Push the back of the wing down firmly against the
wing saddle.
❑Align the predrilled hole in the back of the wing with
the plastic wing mount in the back of the fuselage.
❑Install and tighten one long wood screw through the
rearmost hole to hold the wing firmly in place.
☞Do not overtighten the screw. You don't want to crush
the wing.
Step 6: Installing the Fuselage Top Deck & Canopy
❑Install the top deck by first carefully pushing the back
edge of the top deck into the fuselage opening at the back
of the wing.
Continued on Next Page

8
❑Push the front of the top deck down and align it with
the front of the fuselage and the fuselage sides.
❑Secure the top deck into place by installing and
tightening two long wood screws through the predrilled
holes in the top deck.
IMPORTANT If, after tightening the screws, there is a gap between the top deck and fuselage, remove the top deck and
peel away the protective backing from the strips of double-sided tape on the bottom of the top deck and the top of the
fuselage. Now, when you reinstall the top deck, the double-sided tape will hold the top deck down very securely. If you
should ever need to remove the wing, simply use a modeling knife to cut down the seam before removing the top deck.
❑Carefully remove the protective backing from the strips
of double-sided tape on the bottom of the canopy.
❑Align the canopy with the top deck and gently push it
into place. The double-sided tape will hold it securely.
Step 7: Installing the Propeller
❑Push the propeller firmly onto the motor shaft.
IMPORTANT The propeller should be pushed on firmly,
but the back of the foam spinner should not rub against
the front of the fuselage.

9
Step 8: Installing the Flight Battery
❑Pull the motor on/off switch back toward you to make
sure the motor is in the off position.
❑Turn on the transmitter. Both the green and the red
LEDs should light up.
IMPORTANT Always make sure that you turn on the
transmitter first, before installing the flight battery. After
you're done flying, remove the flight battery first, then turn
off the transmitter.
☞This will prevent unexpected radio signals from
interfering with your radio system.
❑Push the flight battery into the battery tray.
❑Snap the battery cover into place.
IMPORTANT The Extra 300 RTF does not have an
on/off switch. When you plug in the flight battery, the
receiver and servos are powered up.
CAUTION! Do not press the red motor arming switch at
this time.
❑Plug the connector on the flight battery into the connector that is inside the bottom of the fuselage. When
plugged in properly the connectors "click" together.
☞Note that the plugs can be plugged in only one way.

10
Step 1: Adjusting & Checking the Control Surfaces
SECTION 5: TESTING THE EXTRA 300 RTF
❑Make sure the motor on/off switch is in the "off" position, then turn on the transmitter.
❑Plug in and install the flight battery. Do not press the red safety arming switch yet.
❑Carefully adjust the left and right control trim lever
until it is centered with the marks above and below it.
❑Carefully adjust the up and down control trim lever
until it is centered with the marks to the right and left of it.
IMPORTANT Before each flight it's important to check
to make sure that each control surface is exactly even
with the tail. If they are not, the Extra 300 RTF will not
fly properly.
❑If the control surfaces are not exactly even with the
tail, use your fingers to carefully adjust the bend in the
pushrod wire until the back edge of each control surface is
even with the tail.
Continued on Next Page

11
To check that the control surfaces move in the proper direction, do the following:
❑Looking from the back of the Extra 300 RTF, move the right-hand transmitter control stick completely to the left.
The vertical control surface should move left.
❑Looking from the back of the Extra 300 RTF, move the right-hand transmitter control stick completely to the right.
The vertical control surface should move right.
❑Looking from the back of the Extra 300 RTF, move the left-hand transmitter control stick completely back. The
horizontal control surface should move up.
❑Looking from the back of the Extra 300 RTF, move the left-hand transmitter control stick completely forward. The
horizontal control surface should move down.
❑Make sure that the motor on/off switch is pulled back
toward you, then turn on the transmitter and plug in and
install the flight battery.
❑While keeping clear of the propeller, press the red
motor safety arming switch once.
WARNING During the motor test keep everything clear of
the propeller, especially fingers and loose clothing.
❑While holding the Extra 300 RTF upright in the air
with the propeller pointing away from you, push the
motor on/off switch forward. The propeller should spin at
a high rate of speed.
❑When finished with the test, pull the motor on/off switch
toward you (the motor should turn off), unplug the flight
battery, then turn off the transmitter.
Step 2: Checking the Motor

12
The flying field you choose should be a large, open field with grass. There should not be any vehicles, buildings, power
lines, trees, large rocks - or anything else for your Extra 300 RTF to crash into. Until you are proficient with the Extra 300 RTF,
we don't recommend taking off or landing from hard surfaces like asphalt or concrete.
Step 1: Choosing Your Flying Field
SECTION 6: GETTING READY TO FLY
Step 2: Choosing a Day to Fly
❑Until you are comfortable flying your Extra 300 RTF, we suggest flying when there's little to no wind. Do not fly in more
than a 5 m.p.h. wind. To check if there is too much wind to fly your Extra 300 RTF, do the following:
❑Tie the red flag to the end of the transmitter's antenna.
❑Hold the transmitter so the antenna is pointing straight up. If the flag hangs down, go ahead and fly. If the flag hangs
at a 45º angle or more, don't fly. Wait for a calmer day.
Step 3: Range Testing the Radio System
❑Turn on the transmitter. Plug in and install the flight battery. Do not press the motor safety arming switch yet.
❑Set the Extra 300 RTF on the ground and extend the transmitter's antenna completely. Move the two control sticks
back and forth to check the controls.
❑Walk approximately 150ft. from the Extra 300 RTF and move the control sticks back and forth. Check to make sure
that the Extra 300 RTF's controls are moving smoothly at this distance. You may need a friend to help you with this step.
IMPORTANT If the Extra 300 RTF does not range check, don't fly! Please refer to the troubleshooting guide on
page # 15.

SECTION 7: FLIGHT TIPS AND WARNINGS
●Check before every flight to ensure that the batteries in the transmitter are working properly. When the green LED goes
out it's time to change the batteries.
●Before recharging the flight battery, let the motor run until the flight battery is completely drained. This will ensure you
don't overcharge the battery.
●Do not begin to charge the flight battery if it is hot. Wait for the battery to cool before recharging it.

13
●Never leave the flight battery plugged into the airplane unless you are flying or testing the controls.
●Before flying, always double-check that you've extended the transmitter antenna completely.
●Before each flight, do a quick motor test to make sure that the motor is producing full power. If it isn't you may need to
charge the flight battery longer. Do not charge a completely drained flight battery longer than 2 hours or damage to the
flight battery may occur.
●When you fly, orientate yourself so that the sun is at your back. Don't fly directly into the sun or you won't be able to see
your airplane.
●Separate battery packs can be purchased and charged before going to the flying field. An extra flight battery will double
your flight time. See the replacement parts list on page # 14 for the part number of the flight battery.
●Do not fly in winds over 5 miles per hour, otherwise, the airplane will be difficult to control and a crash may occur.
●Do not fly your airplane if another airplane is on the same frequency as you. The frequency number is printed on a
sticker on the back of the transmitter and on the airplane's receiver.
●Always be conscious of the spinning propeller. Be careful not to allow loose clothing to be drawn into the propeller.
●If you're under 12 years of age we suggest you fly while accompanied by an adult.
●Do not use any charger other than the charger included with the Extra 300 RTF to charge the flight battery.
●Never attempt to disassemble any of the Extra 300 RTF components, especially the transmitter, charger and battery.
●Do not allow any of the components to get wet or electrical damage may occur.
●The propeller is a friction fit to the motor shaft. Sometimes the propeller may be knocked loose during a crash or it may
become loose from taking it off. If this is the case, simply apply a thin layer of Elmer's®White Glue to the motor shaft before
installing the propeller. This will help keep it firmly in place. Be careful not to get glue inside the motor.
SECTION 8: FLYING THE EXTRA 300 RTF
Step 1: Hand Launching and Setting the Trim
❑You should always launch the Extra 300 RTF into the wind. Determine wind direction by tossing some blades of grass
into the air and watching which direction they fall.
❑Turn on the transmitter and plug in and install the flight battery. Do not press the motor safety arming switch yet.
Double-check that the control surfaces are centered with the tail.
❑In your throwing hand hold the Extra 300 RTF by the fuselage, under the middle of the wing, just above shoulder height.
❑While holding the transmitter in your other hand, firmly toss the Extra 300 RTF straight ahead and level (without
power). Do not throw it hard or up or down.
IMPORTANT When trimmed properly, the Extra 300 RTF should glide level for a short distance then go into a shallow
nose down attitude for about 20 - 30 feet. Adjust the trim of the horizontal control surface using the up/down trim lever
on the transmitter to achieve this - see below.
●To make the Extra 300 RTF pitch up more, slide the up/down trim lever back just a little bit.
●To make the Extra 300 RTF pitch down more, slide the up/down trim lever forward just a little bit. In most cases, keeping
the up/down trim lever centered will result in excellent power-off glide performance.
❑When you are satisfied with the trim, press the motor arming switch once.
Continued on Next Page

14
❑While holding the Extra 300 RTF at shoulder level like before, push the motor on/off switch to turn the motor on. With
the propeller spinning at high speed, firmly toss the Extra 300 RTF straight ahead and level.
IMPORTANT When trimmed properly, the Extra 300 RTF will gently climb on its own without being given any up/down
stick input. If the Extra 300 RTF begins losing altitude after launching, pull back gently (only a small amount) on the
up/down control stick. This will cause the Extra 300 RTF to pitch up and climb.
Step 2: Flying
❑Since the Extra 300 RTF is designed for those pilots you have flying skills, we won't go much into how to fly the
airplane. It flies pretty much like any other airplane. We will go over a few pointers for you, though.
●Don't make any large control inputs right after hand-launching or you could stall the airplane. Allow the airplane to gain
speed and altitude before making steep turns, dives, climbs, etc.
●The range of the radio system is about 600 feet, so keep that in mind.
●The longer you hold the right/left control stick to either side, the tighter radius the airplane will turn in. We recommend
gentle turns until you're familiar with the airplane's flight characteristics.
●As with most all airplanes, when going into a turn, the Extra 300 RTF will have a natural tendency to lose some altitude.
Unless you want to descend, you should gently pull back on the control stick to keep the airplane level during the turn. The
steeper the turn the more altitude the airplane will lose.
Step 3: Landing
❑Before attempting to land make sure that the Extra 300 RTF is flying straight into the wind with the wing level.
❑Pull the motor on/off switch back toward you to turn the motor off. At this point the Extra 300 RTF will begin to descend.
Allow the airplane to gradually descend. If the airplane seems to be descending too fast, gently pull back on the up/down
control stick to make the airplane pitch up to level flight. This will bleed off speed and slow the decent. Once the airplane
has slowed down, release the control stick and allow the airplane to continue its decent. Once the airplane is about 15 feet
off the ground make sure the wing is level and continue a shallow descent. Just before touch-down, gently pull back on the
control stick to level the airplane with the ground for landing.
