You're ready to start, aren't you? Lets go!
Step 1: Installing the Transmitter Batteries
Remove the battery cover by pushing down with your
thumbs at the two marks shown.
Install 8 fresh AA Alkaline batteries, being careful to
watch that the polarity is correct for each battery.
Push the battery cover back into place until you hear
it "click" into position.
5
Step 2: Charging the Flight Battery
Plug the flight battery connector into the battery
charger connector. When plugged in properly you should
hear the connectors "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. Be
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
Using a small phillips head screwdriver, carefully
remove the screw from the vertical tail mount.
Set the screw aside for now.
Insert the Z-shaped bend (Z-bend) in the pushrod wire
into the middle hole in the plastic control horn on the side
of the vertical tail.
6
When installing the Z-bend, make sure the longer
portion of the wire is facing toward the top of the plastic
control horn.
Carefully push the vertical tail down into the plastic
mount.
Push the tail forward or back to line up the hole though
the side of the tail with the holes in the sides of the mount.
Install and tighten the screw you removed previously
to hold the vertical tail in place.
Do not overtighten the screw or you might strip out
the plastic mount.
7
Step 4: Installing the Landing Gear
Line up the bend in the landing gear wire with the
plastic slot in the bottom of the fuselage.
The slot behind the plastic mount is a cooling slot for
the flight battery.
Push the landing gear wire firmly down into the slot.
Align the propeller with the motor shaft.
Step 5: Installing the Propeller
Continued on Next Page
8
Push the propeller firmly onto the motor shaft.
Step 6: Installing the Wing
Unfold the wing, making sure not to damage the clear
tape that holds the wing halves together.
Do not cut or remove the clear tape that holds the
wing halves together. This tape prevents the wing halves
from coming apart during flight.
Look carefully at the plastic wing brace. Notice that
the top front of the brace is flat.
The front of the wing brace will go toward the front
of the wing.
Continued on Next Page
9
Line up the centerline of the wing with the center of
the fuselage.
Set the plastic wing brace over the middle of the wing.
Remember, the front of the brace goes toward the front
of the wing.
Install the rubber bands to hold the wing brace and
wing firmly in place.
Use two rubber bands per side (four total) to hold the
wing in place.
It is not necessary to use more than four rubber
bands, but if you use less, the wing may move during
flight, resulting in poor flight performance.
10
Step 7: 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
LED's should light up.
IMPORTANT
Always make sure 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 in-
terfering with your radio system.
Remove the rubber bands, wing brace and wing from
the fuselage. Set them aside.
Plug the connector on the flight battery into the
connector that is inside the fuselage. When plugged in
properly you should hear the connectors "click".
Note that the plugs can be plugged in only one way.
Continued on Next Page
11
Push the battery connectors and wires up toward the
front of the fuselage.
Slide the battery down into the fuselage as shown.
Push the flight battery down so it is resting on the
bottom of the fuselage.
The battery simply rests on the fuselage floor, right
in front of the receiver.
IMPORTANT
The Electric Cub 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.
Now that you have completed the assembly of your
Electric Cub, turn to page # 12 to begin testing your
Electric Cub and getting it ready to fly!

Step 1: Adjusting the Control Surfaces
Turn on the transmitter.
Plug in and install the flight battery. Do not press the safety arming switch yet.
Testing the Electric Cub
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.
Continued on Next Page
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 Electric Cub will not fly properly.
If the control surfaces are not exactly even with the
tail, use your fingers to carefully bend the wire (where it
comes out of the fuselage tube) until the back edge of
each control surface is even with the tail.
13
Looking from the back of the Electric Cub, move
the right-hand transmitter control stick completely to
the left. The vertical control surface should move left.
Looking from the back of the Electric Cub, move
the right-hand transmitter control stick completely to the
right. The vertical control surface should move right.
Looking from the back of the Electric Cub, move
the left-hand transmitter control stick completely back.
The horizontal control surface should move up.
Continued on Next Page
14
Looking from the back of the Electric Cub, move
the left-hand transmitter control stick completely forward.
The horizontal control surface should move down.
Step 2: Testing the Motor
Turn on the transmitter and plug in and install the
flight battery.
Make sure that the motor on/off switch is pulled back
toward you - see page # 10.
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 Electric Cub 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.
15
Step 2: Choosing a Day to Fly
Until you become a proficient flyer you should always plan on flying your Electric Cub when there's no wind. We
strongly suggest waiting for a calm day. Do not fly in more than a 5 m.p.h. wind.
Tie the red flag to the end of the transmitter's antenna.
Hold the transmitter up at an angle. 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.
Getting Ready to Fly
Step 1: Choosing Your Flying Field
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 Electric Cub to crash into. Until you are very proficient with the
Electric Cub, we don't recommend taking off or landing from hard surfaces like asphalt or concrete.
Less than a 5 m.p.h. wind.
It's okay to fly.
More than a 5 m.p.h. wind.
Wait for a calmer day to fly.
Continued on Next Page
16
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 Electric Cub on the ground.
Extend the transmitter's antenna completely. Move the two control sticks back and forth to check the controls.
Walk approximately 150ft. from the Electric Cub and move the control sticks back and forth. Check to make sure that
the Electric Cub's controls are moving smoothly at this distance. You may need a friend to help you with this step.
If the Electric Cub does not range check, don't fly! Please refer to the troubleshooting guide on page # 19.
Flying the Electric Cub
Step 1: Hand Launching and Setting the Trim
You should always launch the Electric Cub 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.
In your throwing hand hold the Electric Cub from
the base, up above shoulder level.
While holding the transmitter in your other hand,
firmly toss the Electric Cub straight ahead and level
(without power). Do not throw it hard or up or down.
IMPORTANT
When trimmed properly, the Electric Cub 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.
Continued on Next Page
To make the Electric Cub pitch up more, slide the up/down trim lever back just a little bit.
To make the Electric Cub 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.
While holding the Electric Cub 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 Electric Cub straight ahead and level.
When trimmed properly, the Electric Cub will gently climb on its own without being given any up/down stick input.
If the Electric Cub begins losing altitude after launching, pull back gently (only a small amount) on the up/down control
stick. This will cause the Electric Cub to pitch up and climb.
17
Step 3: Landing
Before attempting to land make sure that the Electric Cub 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 Electric Cub 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 Electric Cub 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
Electric Cub 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.
Step 2: Flying
After you've launched the Electric Cub, keep the motor running and allow the Electric Cub to continue to climb.
After reaching about 80 - 100 feet of altitude you should start making turns to keep the Electric Cub near you.
WARNING
Don't fly the Electric Cub too far away or you could lose control. The range of the radio system is about 500 - 600 feet.
To turn the Electric Cub, gently move the right-hand control stick in the direction you want the Electric Cub to go and
hold it for a second or two. After the Electric Cub starts turning in the direction you want it to, let go of the control stick.
WARNING
The longer you hold the control stick over, the tighter radius the Electric Cub will turn in. We recommend gentle turns
until you are proficient with the flight characteristics of the airplane.
If the Electric Cub always turns one direction or the other, use the sliding trim lever (as described on page # 12) to
make the Electric Cub fly level.
The Electric Cub's altitude is controlled by the left-hand up/down control stick. If you want the Electric Cub to climb,
gently pull back on the control stick. If you want the Electric Cub to descend, gently push forward on the control stick.
When going into a turn, the Electric Cub 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 Electric Cub level during the turn. The steeper the
turn the more altitude the Electric Cub will lose.
Typically, the Electric Cub is flown with the motor on. If you want to glide around or descend, you can turn the motor
off using the motor on/off switch. When you want to climb again, push the motor on/off switch to turn the motor back on.
When you turn the motor off for gliding, the Electric Cub will have a natural tendency to pitch up. This is caused by
the down thrust in the motor. Push forward gently on the left-hand up/down control stick to make the Electric Cub pitch
down to level flight.
IMPORTANT
If you are flying in a light wind, the Electric Cub will tend to climb as you turn into the wind. In this instance, you will
need to level off the Electric Cub by pushing forward on the control stick. When you turn down-wind, the Electric Cub
will have a natural tendency to loss altitude. In this instance, you should pull back gently on the control stick.

Replacement Parts
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.
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 doesn'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 Electric Cub.
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 below for the part number of the flight battery.
Do not fly in winds over 5 miles per hour; otherwise, the Electric Cub will be very difficult to control and a crash will
likely occur.
Do not fly your Electric Cub 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 Electric Cub'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 Electric Cub to charge the flight battery.
Never attempt to disassemble any of the Electric Cub 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 Elmers
®
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.
