The Great Planes Super Sportster has been a favorite
among pilots since1984.For many pilots the Super Sportster
was their first low-wing plane. Now, Great planes brings you
the Super Sportster tradition in an electric park flyer version.
Following the lines of the Super Sportster, the Mini Super
Sportster EP has been lightened to accommodate electric
power without sacrificing performance. If you’re ready to
continue the Super Sportster tradition without the fuss and
mess of a glow engine, the Mini Super Sportster EP is just
what you need.

For the latest technical updates or manual corrections to the
Mini Super Sportster EP visit the Great Planes web site at
www.g reatplanes.com.Open the “Airplanes” link, then select
the Mini Super Sportster EP. If there is new technical
information or changes to this model a “tech notice” box will
appear in the upper left corner of the page.

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.
Though joining the AMA provides many benefits, one of the
primary reasons to join is liability protection. Coverage is not
limited to flying at contests or on the club field. It even applies
to flying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over
2,500 AMA chartered clubs across the countr y. Contact the
AMA at the address or toll-free phone number below:

IMPORTANT!!! Two of the most important things you can do
to preserve the radio controlled aircraft hobby are to avoid
flying near full-scale aircraft and avoid flying near or over
groups of people.

INTRODUCTIONTABLE OF CONTENTS

1.Your Mini Super Sportster EP should not be considered a
toy, but rather a sophisticated, working model that functions
very much like a full-size airplane.Because of its performance
capabilities, the Mini Super Sportster EP ARF, if not
assembled and operated correctly, could possibly cause
injury to yourself or spectators and damage to property.

2. You must assemble the model according to the
instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unflyable model. In a few cases
the instructions may differ slightly from the photos.In those
instances the written instructions should be considered
as correct.

3.You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in first­class condition.

5.You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.

6.You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not an experienced pilot or have not flown this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for your
first flights.If you’re not a member of a club, your local hobb y
shop has information about clubs in your area whose
membership includes experienced pilots.

8. WARNING: The wheel pants included in this kit are made
of fiberglass, the fibers of which may cause eye, skin and
respiratory tract irritation.Never blow into a part (wheel pant)
to remove fiberglass dust, as the dust will blow back into
your eyes. Always wear safety goggles, a particle mask and
rubber gloves when grinding, drilling and sanding fiberglass
parts. Vacuum the parts and the work area thoroughly after
working with fiberglass parts.

Remember:Take y our time and f ollo w the instructions to
end up with a well-built model that is straight and true.

A fully charged battery pack will provide an initial “surge” of
power during the first 15 to 30 seconds of the motor run.
Then the power output stays f airly steady for the ne xt se ver al
minutes before dropping off quickly. If you do not “peak­charge” your battery, it will not deliver that initial surge
necessary for a good takeoff and climb-out.There are three
easy ways to peak-charge your battery pack.

1. The easiest way is with a “peak-detecting” battery charger.
This type of charger will charge your battery until it is fully
charged, then automatically shut off. Using a peak-detecting
charger reduces the chances of damaging the batteries from
over-charging. We recommend the Great Planes Triton™DC
Peak Charger (GPMM3150) to keep your batteries in good
condition or the ElectriFly Peak 400 (GPMM3001).

2.The second method of charging your motor batteries is to
monitor the voltage of your battery pack with a voltmeter
while charging. This method is only recommended for
NiCd batteries. Your charger may have sockets into which
you may plug a voltmeter. If not, you may insert the probes
from the voltmeter into the rear of the battery plug, making
contact with the metal contacts.As your battery charges, the
voltage will gradually increase. When the battery is fully
charged, the voltage will start to drop. At this point your
battery is fully charged. We recommend the Hobbico®905
AC/DC Multi-Charger (HCAP0150).

3. The third (and least reliable) method of peak-charging
your battery pack is by checking its temperature. This
method is only recommended for NiCd batteries. As the
battery charges it will remain cool until it is fully charged.
When it reaches the fully charged state, it will rapidly build
up heat. You can feel this heat with your hand. As soon as
the pack starts to noticeably warm up, disconnect it from the
charger. Do not continue charging if the battery pack is
hot! Overcharging will damage your battery pack and can
result in an explosion.

The Mini Super Sportster EP comes with a BEC type
connector to allow you to change the connector on the
electronic speed control, if needed, to match the connector
supplied on the motor battery, or you may also prefer to use
the connectors of your choice. The one requirement of the
connectors is they must be able to handle a current of at
least 12 Amps.Changing the connectors will require that the
connectors be soldered to the wires from the ESC and the
battery .If you do not have soldering experience, find a fellow
modeler who does and have them help with the soldering.

• There are two types of screws used in this kit:
Sheet metal screws are pointed

and have a coarse thread.
Machine screws have a squared

off end and a fine thread.

Both screws are designated by a number , the diameter, and
the length. For example, a 3 x 8mm screw has a diameter
of 3mm and a length of 8mm.

• When you see the term

test fit

in the instructions, it means
that you should first position the part on the assembly
without using any glue, then slightly modify or

custom fit

the part as necessar y for the best fit.

• Whenever the term

glue

is written you should rely upon
your experience to decide what type of glue to use.When
a specific type of adhesive works best for that step, the
instructions will make a recommendation.

• Whenever just

epoxy

is specified you may use

either

30-minute (or 45-minute) epoxy or6-minute epoxy. When
30-minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.

• Photos and sketches are placed before the step they
refer to .Frequently you can study photos in following steps
to get another view of the same parts.

• The stabilizer and wing incidences and motor thrust angles
have been factory-built into this model. However, some
technically-minded modelers may wish to check these
measurements anyway.To view this information visit the web
site at www.greatplanes.com and click on “Technical Data.”
Due to manufacturing tolerances which will have little or no
effect on the way your model will fly, please expect slight
deviations between your model and the published values.

❏ 1. If you have not done so already, remove the major

parts of the kit from the box (wing, fuselage, tail parts, etc.)
and inspect them for damage. If any parts are damaged or
missing, contact Product Support at the address or
telephone number on the front cover.

❏ 2. Remove the masking tape and separate the ailerons

from the wing and the rudder from the fin. If necessary, use
a covering iron set on medium/high to tighten the covering.
Apply pressure over sheeted areas to thoroughly bond the
covering to the wood.

❏❏1. Test fit the ailerons to

the wing with the supplied CA
hinges. If the hinges don’t stay
centered, stick a pin through
the middle of the hinges to hold
them in position.

❏❏2.Clean the aileron torque rods with denatured alcohol.

❏❏3. Mix a small amount of epoxy. Using a tooth pick,

apply epoxy in the aileron torque rod hole and along the
groove in the leading edge of one of the ailerons.Before the
epoxy sets, join the aileron to the wing. Remove any pins
you may have inserted into the hinges. Adjust the aileron so
there is a very small gap between the LE of the aileron and
the wing. The gap should be small–just enough to see light
through or to slip a piece of paper through.

❏❏4. Apply six drops of thin CA to the top and bottom of

each hinge. Do not use CA accelerator. After the CA
and epoxy have fully hardened, test the hinges by pulling on
the ailerons.

❏ 5. Go back to step 1 and repeat the hinge installation for

the other aileron.

❏ 1. Without using any glue, temporarily join the wings

with the plywood wing joiner. Make adjustments as
necessary for a good fit.Note: The dihedral angle is factory­set and determined by the angle of the joiner and the joining
ribs on the ends of the wing halves. However, you may
confirm the dihedral by placing one wing panel flat on the
workbench and measuring the distance between the bottom
of the rib on the end of the other panel and the bench. The
distance should be 1-7/16" [37mm], but a small variance is
acceptable.If the wing doesn’t fit well or if you can’t get close
enough to the dihedral specified, there may be excess glue
inside the wing or irregularities on the joiner. Use coarse
sandpaper to true the edges and bevel the corners of the
joiner and/or use a hobby knife to remove any glue from the
joiner openings in the ribs on the end of the wing halves.

ASSEMBLE THE WING

PREPARATIONS

7

1-7/16" [37mm]

❏ 2. Prepare 1/2 oz. of 30-minute epoxy. Working quickly,

thoroughly coat the inside of both wing halves where the
joiner fits and one half of the joiner with epoxy. Making certain
the joiner is upright, insert the coated end into one of the
wing halves.Coat the other end of the joiner and the root ribs
with the remainder of the epoxy. Join the wing halves tightly,
holding them together. Use a paper towel dampened with
denatured alcohol to wipe away the e xcess epo xy that comes
out of the wing. Tightly hold the wing together with several
strips of masking tape on the top and bottom, making certain
both halves are in full contact and the leading and trailing
edges are aligned. Let the wing set until the epoxy has set.

❏ 1. Cut the covering from the four wing mounting dowel

holes on the sides of the fuselage.

❏ 2. Center the two 4mm x 80mm hardwood wing mounting

dowels in the holes.Use thin CA to glue the dowels in place.

❏ 3.Install the wing on the fuselage using four rubber bands.

❏ 1. Using a shar p hobby knife, remove the covering from

the stabilizer slot at the aft end of the fuselage and from the
rudder slot in the top of the fuselage. Also remove the
temporary balsa block from the stabilizer slot.

❏ 2. Mark the center of the trailing edge of the stabilizer.

Insert the stabilizer into the slot, centering the mark you made
on the TE of the stabilizer with the aft end of the fuselage.

❏ 3. Stick a T-pin into the center of the top of the firewall.

Tie a small loop in one end of a 36" [910mm] piece of non­elastic string such as K&S #801 Kevlar thread.Slip the loop
in the string over the T-pin.

❏ 4. Fold a piece of masking tape over the other end of the

string and draw an arrow on it.With the stab centered on the

fuselage, slide the tape along the string and align the arrow
with one tip of the stab. Swing the string over to the same
position at the other end of the stab. If the arrow doesn’t
align with the tip, adjust the stab and the arrow slightly and
check both tips again.Adjust the stab until the stabilizer tips
and the trailing edge are centered.

❏ 5.View the stab from approximately 10' [3m] behind the

plane.Check that the stab is parallel with the wing.If it is not,
lightly sand the stab saddle until the stab is parallel with
the wing.

❏ 6. Use a fine-point felt-tip pen to mark the outline of the

fuselage onto the bottom and top of the stab.

❏ 7. Remove the stab from the fuselage. Use a sharp #11

hobby knife or the Expert Tip that follows to cut the covering
from the stab just inside the lines you marked. Use care to
cut only the covering and not the wood. Cutting the wood
will weaken the stab and it may break in flight.

9

HOW TO CUT COVERING FROM BALSA

Use a 25 watt soldering iron to cut the covering from the stab.
The tip of the soldering iron doesn’t have to be sharp, but a
fine tip does work best.Allow the iron to heat fully .Use a metal
straightedge to guide the soldering iron at a rate that will just
melt the covering and not burn into the wood.The hotter the
soldering iron, the faster it must travel to melt a fine cut.Allow
the heat to melt the covering.Do not apply much pressure or
the wood may be damaged.Peel off the covering.

❏ 8. Apply a light coat of 30-minute epoxy in the stabilizer

slot and the top and bottom of the stabilizer. Slide the
stabilizer into position. Make sure the stabilizer is centered
from side-to-side using the string method to re-align the stab
with the fuselage. Inser t the fin into the fin slot, but do not
insert it completely. The fin is used to space the fin slot
correctly while the epoxy sets. Wipe off the excess epoxy
with a paper towel dampened with denatured alcohol. Allow
the epoxy to set completely before installing the fin.

❏ 9. Fit the fin all the way into the fin slot.Again, use a felt-

tip pen to mark the fuselage onto the fin. Remove the fin
from the fuselage and remove the covering from the fin.

❏ 10. Glue the fin into position using epoxy. Use a builder’s

square to make sure the fin is perpendicular to the stab.
Wipe off the excess epoxy with a paper towel dampened
with denatured alcohol. Masking tape can be used to hold
the fin in position until the epoxy sets.

❏ 11. Use a sharp hobby knife to trim the covering from the

notch in the leading edge of the rudder.

❏ 12. Join the rudder to the fin using three CA hinges. Use

thin CA to glue the CA hinges in the rudder and fin following
the same procedure used for the ailerons.

❏ 1. Position one of the aluminum motor brackets 1/4"

[6mm] back from the forward edge of the mounting rails.Set
the motor on the motor bracket so that the aft edge of the
motor is 3/16" [5mm] from the firewall.

MOUNT THE MOTOR

10

❏ 2. Place the second motor bracket over the motor and

drill a 1/32" [.8mm] pilot hole at each mounting hole in the
motor bracket. Secure the motor brackets to the mounting
rail with 2x7mm sheet metal screws. Rotate the
motor/geardrive so that the gear drive is aligned with the
firewall.Then tighten the screws.

❏ 3. Use the hex wrench to loosen the set screw in the prop

adapter and remove the prop adapter from the gear drive.
Tape a piece of paper to each side of the fuselage e ven with
the front of the fuselage.

❏ 4. Slide the cowl onto the fuselage and under the paper.

Reinstall the prop adapter on the gear drive. Tighten the set
screw on the flat of the gear drive output shaft.Tape the cowl to
the fuselage so that the prop adapter is centered in the hole in
the front of the cowl and the front of the cowl is approximately
1/16" [2mm] back from the flange on the prop adapter.

❏ 5.Drill two 1/32" [.8mm] holes through both sides of the

cowl and the fuselage 1/8" [3mm] behind the front edge of
the paper. Remove the cowl and the paper. Enlarge the
holes in the cowl only with a 1/16" [2mm] drill.Then, mount
the cowl with four 2x7mm washer-head screws.

❏ 6. Remove the screws and cowl.Apply a drop of thin CA

in each hole to harden the wood.Reinstall the cowl and prop
adapter after the CA has hardened.

Note: You will need to have your 8-cell motor battery
charged later in this section. Star t charging it now so
you do not have to wait for it to charge later.

Install the Control Horns

RADIO INSTALLATION

11

❏ 1. Inser t the two wire pushrods into the outer pushrod

tubes inside the fuselage. Using a sharp hobby knife, cut a
small slot in the covering, where the pushrods press against
the covering, to allow the pushrods to exit the fuselage.

❏ 2.Remove and reinstall the pushrods so that the Z-bends

are at the aft end of the fuselage. On the right pushrod,

insert the Z-bend into the outer hole of a nylon control horn.
This pushrod will be for the elevator. On the left pushrod,
insert the Z-bend into the second hole from the end. Position
the control horn on the elevator so that the attachment holes
are aligned with the hinge line.

❏ 3. Mark the two control horn mounting holes on the

elevator. Remove the control horn and drill 5/64" [2mm]
holes through the elevator at the marks. Mount the control
horn with two 2x9mm machine screws and the nylon
mounting plate on the top of the elevator.

❏ 4. Install the rudder control horn following the same

procedure. Make sure that the control horn does not
interfere with the elevator.

❏ 1. Install a pushrod connector on the elevator servo arm,

1/4" [6mm] from the center of the servo arm. Install a second
pushrod connector on the rudder servo arm, 5/16" [8mm]
from the center of the servo arm. First insert the pushrod
connector though the horn, then install a 2mm washer and
a 2mm nut on the connector.Install a 3mm set screw in the
top of the pushrod connector.

❏ 2. Install the r udder and elevator servos in the servo tray.

Insert the pushrods through the pushrod connectors and
install the servo arms on the rudder and elevator servos.Align
the pushrod connectors with the pushrods.Use the hardware
included with the servos to mount the servos to the tray.

❏ 3. Cut a piece of soft hook-and-loop material and use CA

to glue it to the bottom of your receiver .Cut an opposite piece
of the hook-and-loop material and glue it to the bottom of the
battery tray, centered between the three slots. Connect the
rudder and elevator servos to the receiver and mount the
receiver to the battery tray. Optional: Use double-sided foam
tape (not included) to attach the receiver to the battery tray.

❏ 4.Trim the covering from the five cooling air exit holes aft

of the wing saddle. Route the receiver antenna out one of
the holes and tape it to the bottom of the fuselage.

❏ 5. Connect the electronic speed control (not included) to

the motor leads. If the ESC to be installed does not have
bullet connectors, you will need to install the included
connectors on the ESC. If the ESC has an on/off switch,
mount it through the side of the fuselage. Connect the ESC
to the throttle channel in the receiver.

❏ 6. Use a sharp kniffe to strip 3/16" [5mm] of the insulation

from the end of the ESC wire. Insert the wire in the bullet
connector and use pliers to crimp the connector around the
wire.Place a piece of clear heat shrink aound the connector
and use a heat gun to shrink it.

❏ 7. Switch on the transmitter, connect the charged motor

battery and switch on the ESC. Center the rudder and
elevator trims. If necessary, remove the servo arms and
reinstall them perpendicular to the centerline of the ser vo.
Reinstall the servo arm screws.

❏ 8. Center the elevator and rudder, then tighten the set

screws in the pushrod connectors. Trim off the excess
pushrod wires 1/4" [6mm] past the connectors.

❏ 9. Mount the aileron servo in the wing. Connect a 6"

[150mm] aileron servo extension to the receiver. Connect
the aileron servo to the servo extension and switch on the
transmitter and ESC.Center the aileron servo trim.

❏ 10. Install a two-arm servo arm with both holes 5/16"

[8mm] from the center of the arm.

❏ 11. Thread the two nylon torque rod horns onto the

aileron torque rods. The bottom of the horn should be
approximately 7/16" [11mm] from the wing.

❏12.Insert one end of the aileron pushrods into the torque rod

horns. Insert the other end into the ser vo arm. Install the ser vo
arm on the aileron servo and install the servo arm screw. To
adjust the ailerons, open or close the V-bends in the pushrods.

❏ 1. Trim the covering from the main landing gear slot in the

bottom of the fuselage and insert the main landing gear wire.

❏ 2. Insert the plywood landing gear retainer in the slot. It

can either be glued in or held in place with clear tape.

❏ 3. Install both wheel pants and foam wheels by inserting

the landing gear in one side of the wheel pant, then through
the foam wheel and out the other side of the wheel pant.

MOUNT THE LANDING GEAR

14

❏ 4. With the plane sitting on the bench, adjust the wheel

pant so that the bottom is 3/8" [9mm] from the bench.

❏ 5. Position one of the metal landing gear straps over the

main gear, against the wheel pant. Mar k the screw holes,
remove the strap and drill a 1/32" [.8 mm] pilot hole at each
mark. Mount the straps to the wheel pants with 2x4mm
sheet metal screws.

❏ 1. Use a scissors designed to cut plastic to carefully trim

the canopy along the molded cut lines.

❏ 2.Center the canopy on the fuselage.Cut a canopy hinge

strip from the decal sheet.Attach the canopy to the right side
of the fuselage with the decal hinge strip.

❏ 3. Use a piece of tape to hold the left side of the canopy

tight to the fuselage. Note the location of the plywood
doubler inside the cockpit side wall.Drill a 1/16" [2mm] hole
through the canopy and plywood doubler. Enlarge the hole
in the fuselage to 7/64" [3.5mm]. Apply a drop of thin CA to
the hole in the fuselage.After the CA has hardened, run the
drill back though the hole to clean it out.

❏ 4. Attach the 2.3 x 12mm tube to the inside of the canopy

with a 2x7mm sheet metal screw.

❏ 5.To close the canopy, insert the tube in the hole in the

side of the fuselage.

❏ 1. To make the battery strap, overlap the two pieces of

hook-and-loop material as shown.

❏ 2.Insert the hook-and-loop strap through the middle slots

from the bottom of the battery tray. Position the strap over
the receiver to help hold it in place.

❏ 3. Insert the motor battery in the cockpit and trim the

hook-and-loop strap so that it holds the battery secure.

❏ 4.To prevent the battery from sliding around, glue a piece

of hook-and-loop material to the battery tray forward of the
strap. Once the plane has been balanced and the battery
location has been determined, glue a corresponding piece
of hook-and-loop material to the battery.

1.Use scissors or a sharp hobby knife to cut the decals from
the sheet.

2.Be certain the model is clean and free from oily fingerprints
and dust.Prepare a dishpan or small bucket with a mixture of
liquid dish soap and warm water–about one teaspoon of
soap per gallon of water.Submerse the decal in the soap and
water and peel off the paper backing.Note: Even though the
decals have a “sticky-back” and are not the water transfer
type, submersing them in soap and water allows accurate
positioning and reduces air bubbles underneath.

3. Position decal on the model where desired. Holding the
decal down, use a paper towel to wipe most of the water a way.

4. Use a piece of soft balsa or something similar to
squeegee remaining water from under the decal. Apply the
rest of the decals the same way.

Warning: Once the motor battery is connected to the
electronic speed control, stay clear of the propeller.

❏ 1. Switch on the transmitter and connect the motor

battery to the electronic speed control. Move the throttle
stick down to the off position. Switch on the speed control
and center the trims. If necessary, remove the servo arms
from the servos and reposition them so they are centered.
Reinstall the screws that hold on the servo arms.

❏ 2. With the transmitter and receiver still on, check all the

control surfaces to see if they are centered. If necessary,
adjust the pushrods at the pushrod connectors to center the
control surfaces.

❏ 3. Make certain that the control surfaces respond in the

correct direction as shown in the diagram. If any of the

to those controls. Be certain the control surfaces have
remained centered. Adjust if necessary.

❏ 4. To operate or “arm” the motor, follow the instructions

included with your electronic speed control.

Use a Great Planes AccuThrow (or a ruler) to accurately
measure and set the control throw of each control surface as
indicated in the chart that follows.If your radio does not hav e
dual rates, we recommend setting the throws at the low rate
setting.NOTE: The throws are measured at the widest part
of the elevators, rudder and ailerons.

❏ 1. Drag the edge of a hobby knife along the edge of the

propeller to remove the sharp edges.

❏ 2. Remove the prop washer and screw from the prop

adapter.Install the propeller on the prop adapter and secure
it with the prop washer and screw.

❏ 3.Check the rotation of the prop by switching on the radio

system and arming the ESC. Move the throttle stick to full
power. If the prop is turning the wrong direction (no air
blowing back towards the fuselage), switch the leads
between the motor and the ESC.

Mount the Propeller

IMPORTANT: The Mini Super Sportster EP has been
extensively flown and tested to arrive at the throws at

which it flies best. Flying your model at these throws will
provide you with the greatest chance for successful first
flights. If, after you have become accustomed to the way
the Mini Super Sportster EP flies, you would like to
change the throws to suit your taste, that is fine.However,
too much control throw could make the model difficult to
control, so remember, “more is not always better.”

These are the recommended control surface throws:

High Rate Low Rate

ELEVATOR: 5/16" [8mm] up 3/16" [5mm] up

5/16" [8mm] down 3/16" [5mm] down

RUDDER: 1" [25mm] right 3/4" [19mm] right

1" [25mm] left 3/4" [19mm] left

AILERONS: 1/4" [6mm] up 1/8" [3mm] up

1/4" [6mm] down 1/8" [3mm] down

Set the Control Throws

17

At this stage the model should be close to ready-to-fly
condition with all of the systems in place including the motor,
landing gear, motor battery, and the radio system.

❏ 1.Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately

mark the C.G. on the top of the wing on both sides of the
fuselage.The C.G. is located 2-3/16" [56mm] back from the
leading edge of the wing.

❏ 2.With the wing attached to the fuselage, all parts of the

model installed (ready to fly) and the motor battery installed,
place the model upside-down on a Great Planes CG Machine,
or lift it upside down at the balance point you marked.

❏ 3. If the tail drops, the model is “tail heavy” and the motor

battery and/or receiver must be shifted forward or weight m ust
be added to the nose to balance.If the nose drops, the model
is “nose hea vy”and the motor battery and/or receiver must be
shifted aft or weight must be added to the tail to balance. If
possible, move the motor battery and receiver forward or aft

to minimize or eliminate any additional ballast required. If
additional weight is required, use Great Planes [GPMQ4485]
“stick on”lead. A good place to add stick-on nose weight is to
the firewall (don’t attach weight to the cowl-it is not intended
to support weight). Begin by placing incrementally increasing
amounts of weight on the bottom of the fuse over the firewall
until the model balances. Once you have determined the
amount of weight required, it can be permanently attached. If
required, tail weight may be added by cutting open the bottom
of the fuse and gluing it permanently inside.

If moving the motor battery forward or aft will balance the
plane without adding additional weight, mark the battery tray
or the fuselage inside where the aft end of the battery
should be placed. This will allow you to position the battery
correctly before each flight.

❏ 4. IMPORTANT: If you found it necessary to add any

weight, recheck the C.G.after the weight has been installed.

❏1.With the wing level lift the model by the prop shaft and the

bottom of the fuse under the TE of the fin.Do this several times.

❏ 2. If one wing always drops when you lift the model,

it means that side is heavy. Balance the airplane by
adding weight to the other wing tip. An airplane that has

been laterally balanced will track better in loops and
other maneuvers.

No matter if you fly at an AMA sanctioned R/C club site or if you
fly somewhere on your own, you should always have your
name, address, telephone number and AMA number on or
inside your model.It is required at all AMA R/C club flying sites
and AMA sanctioned flying events. Fill out the identification tag
on page 23 and place it on or inside your model.

Follow the battery charging instructions that came with your
radio control system to charge the transmitter. You should
always charge your transmitter the night before you go flying
and at other times as recommended by the radio manuf acturer .

Charge the Batteries

PREFLIGHT

Balance the Model Laterally

This is where your model should balance for the first
flights. Later, you may wish to experiment by shifting the
C.G. up to 3/16" [5mm] forward or 3/16" [5mm] back to
change the flying characteristics. Moving the C.G. forward
may improve the smoothness and stability, but the model
may then require more speed for tak eoff and mak e it more
difficult to slow for landing.Moving the C.G.aft makes the
model more maneuverable, but could also cause it to
become too difficult to control. In any case, start at the
recommended balance point and do not at any time
balance the model outside the specified range.

More than any other factor, the C.G. (balance point) can
have the greatest effect on how a model flies and may
determine whether or not your first flight will be
successful. If you value this model and wish to enjoy it for
many flights, DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE. A model that is not proper ly balanced will
be unstable and possibly unflyable.

Balance the Model (C.G.)

18

2-3/16" [56mm]

Carefully balance your propeller and spare propellers before
you fly. An unbalanced prop can be the single most
significant cause of vibration that can damage your model.
Not only will motor mounting screws and bolts loosen,
possibly with disastrous effect, but vibration may also
damage your radio receiver and battery.

We use a Top Flite Precision Magnetic Prop Balancer

™

[TOPQ5700] in the workshop and keep a Great Planes
Fingertip Prop Balancer [GPMQ5000] in our flight box.

1. The included motor will benefit from a shor t “break-in” by
running the motor at full throttle without the propeller for at
least 15 minutes. It is best to run the motor in 5 minute
intervals, allowing the motor to cool between runs.This will
seat the motor brushes on the commutator, insuring that the
motor will provide full power for your first flight and extend
the life of your motor. If you notice a decrease in motor
power after several flights, it may be due to carbon build-up
on the brushes or commutator. To remove this build-up,
repeat the above break-in procedure.

2.The bronze bushings in the motors are self lubricating, but
their life may be extended by applying a very small amount
of light machine oil to the point where the motor shaft
contacts the bushings after every hour or two of run time.
Note: A drop of oil is far too much.You should apply the oil
with a toothpick. Never oil the inside of the motor.

3. Using multiple battery packs to run the motor for
successive flights may cause the motor to become
excessively hot.We recommend at least a 10-minute motor
cool-down period between flights.

1.A new battery pack should be “cycled”for best results.You
should peak charge the battery, then discharge it almost
completely by actually running your motor with the propeller
attached until the auto cut-off stops the motor.To help cool
the battery, remove the battery from the plane. Do this 2 or
3 times on the ground before actually flying. Be sure you
remove the battery from the airplane between each cycle
and allow it and the motor to cool before recharging.

2. Examine your propeller for irregularities caused by the
injection molding process.Carefully remove the imperfections
with fine sandpaper.

After you break-in the motor on the model, inspect the
model closely to make sure all screws remained tight, the
hinges are secure, the prop is secure and all pushrods and
connectors are secure.

Ground check the operational range of your radio before the
first flight of the day. With the transmitter antenna collapsed
and the receiver and transmitter on, you should be able to
walk at least 100 feet [30m] away from the model and still
have control. Have an assistant stand by your model and,
while you work the controls, tell you what the control surf aces
are doing. Repeat this test with the motor running at
various speeds with an assistant holding the model, using
hand signals to show you what is happening. If the control
surfaces do not respond correctly, do not fly! Find and
correct the problem first.Look for loose servo connections or
broken wires, corroded wires on old servo connectors, poor
solder joints in your battery pack or a defective cell, or a
damaged receiver crystal from a previous crash.

PERFORMANCE TIPS

PROPER CARE OF YOUR MOTOR

Balance Propellers

CAUTION: Unless the instructions that came with your

radio system state differently, the initial charge on new
transmitter and receiver batteries should be done for 15
hours using the slow-charger that came with the radio
system.This will “condition” the batteries so that the next
charge may be done using the fast-charger of y our choice.
If the initial charge is done with a fast-charger the
batteries may not reach their full capacity and you may be
flying with batteries that are only partially charged.

19

Use safety glasses when running the motor.
Do not run the motor in an area of loose gravel or sand;the

propeller may throw such material in your face or eyes.
Keep your f ace and body as w ell as all spectators a wa y from

the plane of rotation of the propeller as you run the motor.
Keep these items away from the prop: loose clothing, shir t

sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.

The Mini Super Sportster EP is a great-flying model that flies
smoothly and predictably. The Mini Super Spor tster EP does
not, however, possess the self-recovery characteristics of a
primary R/C trainer and should be flown only by experienced
R/C pilots.

The Mini Super Sportster EP will ROG (rise off ground) very
easily from a smooth runway. Point the plane into the wind
and apply power. Once the plane gains some speed the
rudder can be used to control the direction. Because the
plane does not have a steerable tail wheel, taking off in a
cross-wind is very difficult and a hand launch is
recommended. Once the plane has gained speed,

gently

apply

up elevator , lifting the model into the air.Be smooth on

the elevator stick, allowing the model to establish a

gentle

climb to a safe altitude before turning into the traffic pattern.
If you do not have a smooth runwa y to tak e-off from, the Mini

Super Sportster EP can easily be hand launched. For the
first flight we recommend that the plane be hand launched
by an assistant. This will allow you to make quick control
corrections if the plane is out of trim.The plane only requires
a gentle level toss straight out.Do not throw the plane hard.
This usually results in a plane being thrown at a poor angle
requiring sudden drastic control corrections.Once the plane
has been trimmed to fly straight and level, it is very easy for
the pilot to hand launch the plane.

For reassurance and to keep an eye on other traffic, it is a
good idea to have an assistant on the flight line with you.Tell
him to remind you to throttle back once the plane gets to a
comfortable altitude.While full throttle is usually desirable for
takeoff, most models fly more smoothly at reduced speeds.

Tak e it easy with the Mini Super Sportster EP for the first few
flights, gradually getting acquainted with it as you gain
confidence. Adjust the trims to maintain straight and level
flight. After flying around for a while, and while still at a safe
altitude with plenty of battery power remaining, practice slow
flight 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. Continue to fly
around, executing various maneuvers and making mental
notes (or having your assistant write them down) of what trim
or C.G.changes may be required to fine tune the model so it
flies the way you like. Mind your battery power and use this
first flight to become familiar with your model before landing.

To initiate a landing approach, lower the throttle while on the
downwind leg.Allow the nose of the model to pitch downward
to gradually bleed off altitude. Continue to lose altitude, but
maintain airspeed by keeping the nose down as y ou turn onto
the crosswind leg. Make your final turn toward the runway
(into the wind) keeping the nose down to maintain airspeed
and control. Level the attitude when the model reaches the

Landing

Flight

Takeoff

CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If,
while flying, you notice an alarming or unusual sound
such as a low-pitched “buzz,” this may indicate control
surface

flutter

.Flutter occurs when a control surface (such
as an aileron or elevator) or a flying surface (such as a
wing or stab) rapidly vibrates up and down (thus causing
the noise). In extreme cases, if not detected immediately,
flutter can actually cause the control surface to detach or
the flying surface to fail, thus causing loss of control
followed by an impending crash. The best thing to do
when flutter is detected is to slow the model immediately
by reducing power, then land as soon as safely possible.
Identify which surface fluttered (so the problem may be
resolved) by checking all the servo grommets for
deterioration or signs of vibration. Make certain all
pushrod linkages are secure and free of play. If it fluttered
once, under similar circumstances it will probably flutter
again unless the problem is fixed.Some things which can
cause flutter are; Excessive hinge gap; Not mounting
control horns solidly; Poor fit of clevis pin in horn; Side­play of wire pushrods caused by large bends; Excessive
free play in servo gears; Insecure servo mounting; and
one of the most prevalent causes of flutter;Flying an over­powered model at excessive speeds.

runway threshold, modulating the throttle as necessary to
maintain your glide path and airspeed. If you are going to
overshoot, smoothly advance the throttle (alw ays ready on the
right rudder to counteract torque) and climb out to make
another attempt. But, if your battery power is low do not
attempt to go around again. It is better to land long than risk
stalling the plane by flying too slow because the motor battery
is low on power .When you’re ready to make your landing flare
and the model is a foot or so off the deck, smoothly increase
up elevator until it gently touches down.

One final note about flying your model. Have a goal or flight
plan in mind for every flight. This can be learning a new
maneuver(s), improving a maneuver(s) y ou already kno w, or
learning how the model behaves in certain conditions (such
as on high or low rates). This is not necessarily to improve
your skills (

though it is never a bad idea!

), but more

importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly finding that you’ve run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive.For example, if you’re going to do
a loop, check your altitude, mind the wind direction
(anticipating rudder corrections that will be required to
maintain heading), remember to throttle back at the top, and
make certain you are on the desired rates (high/low rates).
A flight plan greatly reduces the chances of crashing your
model just because of poor planning and impulsive moves.

Remember to think.

Have a ball!

But always stay in control and fly in a safe manner.

GOOD LUCK AND GREAT FLYING!
