SPECIFICATIONS
The plane that started it all, the Model Tech Magic is a classic among 3D enthusiasts. For today's pilot, Model Tech has updated this
original Mark Leavesley design to incorporate everything the modeler has desired. First, we made it more easily electric compatible.
A door on the bottom of the fuselage, in addition to the removable throttle servo tray, allow easy access to the battery. For the glow
engine enthusiast, the rewall has been modied to make engine installation easier, including slots for the engine mounting screws
that allow the installation of different width motors. We also upgraded the hardware with traditional pull/pull cables (not rods) for the
elevator and rudder. We even made the wing bolt-on with nylon bolts threaded into hardwood, which is tapped at the factory. All
this in a model that is now laser-cut for precision and covered with a new, more aggressive color scheme in high-quality Model Tech
iron-on covering material. Model Tech engineers have been hard at work giving you a plane you know ies great, with the features
you want, in a plane that is affordable and fun. Put some Magic in your ying with the Magic V2 from Model Tech.

SAFETY WARNING

Page 3
This section describes our recommendations to help you in deciding which types of accessories to purchase for your new airplane.
Please read through this entire section very carefully. We have provided you with recommendations that,
if followed, will result in a great ying airplane. Failure to follow our recommendations may result in a poor
ying airplane.
OUR RECOMMENDATIONS - GLOW POWER SYSTEM
WHAT ENGINE SHOULD I USE?
WHAT RADIO SYSTEM AND SERVOS SHOULD I USE?
HERE'S A LIST OF WHAT WE USED TO FINISH THE GLOW VERSION SHOWN IN THESE INSTRUCTIONS
QTY. 1 Hitec Eclipse 7 FM Radio Control System
QTY. 1 210756 Magnum XLS .46A Two-Stroke Engine
QTY. 1 237153 Magnum 2-1/4" Diameter Chrome Spinner
QTY. 1 608684 APC 12.25 x 3.75 Composite Propeller
QTY. 1 440501 Cirrus CS501 Low Prole Ball Bearing Servo
QTY. 4 440601 Cirrus CS601 Standard Ball Bearing Servos
WHAT OTHER ITEMS DO I NEED?
IMPORTANT The Cirrus servos are compatible with all receiver types. The Magnum spinner includes a 1/4" x 4mm adapter nut that ts any
engine that uses a 1/4"-28 threaded crankshaft.
There really isn't too much else that you'll need to nish the airplane. Most of the hardware is included, so about the only thing else
you'll need is a spinner. You'll also need typical modeling supplies, such as foam rubber to protect your receiver and battery, and
fuel tubing.
QTY. 1 115559 Thunderbolt # 3 High-Performance Glow Plug
QTY. 1 115923 Global XX Silicone Fuel Tubing
QTY. 1 868638 Dubro 1/4" Protective Foam Rubber
The airplane can be own using either a two-stroke or a four-stroke engine. We suggest using a .36 - .46
size two-stroke engine or a .52 size four-stroke engine. The airplane will y great using any engine within
the recommended size range, although for the best aerobatic performance we suggest using an engine at
the upper end of the size range. For 3D ying, you'll get the best performance
using a lightweight yet powerful engine, such as the Magnum XLS .46A two-
stroke engine matched with a large diameter, low pitch propeller, such as the
APC 12.25 x 3.75 composite propeller.
For the best ight performance, we suggest trying to keep the ready-to-y weight of the airplane as light
as possible. Using an engine that's bigger than recommended will only add extra weight to the airplane,
negating any of the extra power from the larger engine. In most cases, you'll get better ight performance
from a lightweight but powerful engine than from simply a higher displacement engine. 

To get the most out of the airplane, we suggest using a four or more channel computer radio system with mixing capabilities. Since the
ailerons use separate servos, they can be plugged separately into the receiver,
allowing you the capability of aperon and spoileron mixing, differential mixing and
aperon/spoileron to elevator mixing. The transmitter should also feature dual rates
and exponential adjustments.
Standard servos can be used on the ight-control surfaces, although we do
recommend using the ball bearing type. 

servo can be used. We recommend using a Cirrus CS501 Ball Bearing Low Prole servo for elevator control and Cirrus CS601 Ball
Bearing Standard servos for aileron, rudder and throttle control.
Although you would lose mixing capabilities, the airplane can be own using a basic four-channel radio control system. If you do this,
you will need to use a servo Y-Harness to join the two aileron servos together.

QTY. 1 158370 Pro-Peak Quattro LiPO Charger
WHAT OTHER ITEMS DO I NEED?
IMPORTANT The Cirrus servos are compatible with all receiver types. The Hitec Electron 6 FM receiver is negative shift that's compatible with
Hitec and Futaba transmitters. This receiver is also available in positive shift mode for Airtronics and JR transmitters. The Electron 6 FM receiver
requires a Hitec 72Mhz FM crystal purchased separately that's the same frequency as your transmitter.
There really isn't too much else that you'll need to nish the airplane. Most of the hardware is included, so about the only thing else
you'll need is a spinner, hook and loop material, heat-shrink tubing, double-sided tape and high-quality connectors for your ESC,
Motor and LiPO battery.
For the best ight performance, we suggest trying to keep the ready-to-y weight of the airplane as light as possible. For the most
power, lightest weight and best performance, we suggest using a direct drive, brushless Outrunner motor, such as the KMS Quantum
4120/05 brushless motor, APC 13 x 6 composite propeller, Castle Creations Phoenix 60 amp brushless ESC and Impulse Power
4C 4000mAH LiPO battery. This combination will provide ample power, resulting in great overall ight characteristics.
To get the most out of the airplane, we suggest using a four or more channel computer radio system
with mixing capabilities. Since the ailerons use separate servos, they can be plugged separately into
the receiver, allowing you the capability of aperon and spoileron mixing, differential mixing and

TIPS FROM THE PROS
lDuring the covering process, sometimes color may smear slightly from the seams. If you see any smeared colors on the covering
material, it can be quickly removed by simply wiping it off with a paper towel and a small amount of acetone.
l Make sure to test-t the parts together before applying glue. This will ensure that the parts t properly before gluing them together.
lWhen gluing anything that has a smooth surface, it's important to lightly roughen the gluing surfaces with 220 grit sandpaper. This
will allow the glue to stick better. Also, never glue directly to the covering material. Always remove the covering material from the
gluing surfaces prior to gluing the parts together.
lWhen cutting away the covering material from the gluing surfaces, be careful to cut only through the covering material. Try not to
cut down into the balsa structure because that can compromise the integrity of the airframe.
lWe do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct sunlight) for any length
of time. The extreme heat could cause the covering material to wrinkle or sag and possibly damage the fragile components of the
radio control system.
lEpoxy can be cleaned up before it dries using rubbing alcohol and C/A can be cleaned up before it dries using C/A Debonder.
TOOLS AND SUPPLIES REQUIRED
The covering material used on your airplane is real iron-on, heat-shrink covering material. It is possible with heat and humidity changes
that the covering material on your airplane may wrinkle or sag. This trait is inherent in all types of heat-shrink material. To remove
any wrinkles that might be visible you will need to use a heat-sealing covering iron.

qPlug in and turn on the sealing iron to the medium-high temperature setting. Allow the sealing iron to heat up for approximately
5 - 7 minutes.
qAfter the sealing iron has reached temperature, lightly apply the sealing iron to the wrinkled section of the covering material. Move
the sealing iron slowly over the wrinkled section until the covering material tightens and the wrinkles disappear.
A NOTE ABOUT COVERING MATERIAL
+If the color layer smears from any of the seams the temperature of the sealing iron is too hot. Turn the temperature dial down
and wait about 5 minutes for the sealing iron to adjust to the lower temperature. You can remove any excess color streaks using a
paper towel soaked with a small quantity of acetone.
IMPORTANT You will notice that the color of the covering material will darken when it is heated. When the covering material
cools back down, it will return to its normal color.

IMPORTANT The hinges are preglued into only the control surfaces. You must still hinge the control surfaces to the ying
surfaces.
C/A-style hinges are used to hinge the control surfaces. These hinges are designed to be glued into place using thin C/A. Do not
glue these hinges into place using any other type of glue, such as thick C/A or epoxy. Use of any adhesive other than thin C/A
could result in failure of the hinges during ight.
For utter-free control surfaces and crisp control response, it is imperative that the hinges be glued in properly. This is achieved
by having the correct hinge gap and using plenty of thin C/A glue. Poor hinge installation can lead to control surface utter which
can result in a catastrophic failure of the airframe.
STEP 1: HINGING THE AILERONS

Page 9
qWorking with one wing panel for now, remove the aileron from the wing
panel, then push one T-Pin through the center of each of the four preinstalled
C/A-style hinges.
PRO TIP The T-Pins will set the proper hinge gap when you hinge the
aileron to the wing panel.
qPush the aileron and hinges into the corresponding four hinge slots in
the trailing edge of the wing panel. If you cannot push the aileron rmly up
against the T-Pins, remove the aileron and cut the hinge slots in the wing
panel deeper.
q Push the aileron rmly up against the T-Pins and double-check that there
is no more than a 1/16" (1.5mm) wide gap between the tip of the aileron and
the wing tip.
qWhile holding the aileron tight against the T-Pins, pivot the aileron down
45º and apply 5-6 drops of thin C/A to the exposed area of each hinge, then
turn the wing panel over and repeat for the other side of the hinges.
qAllow the C/A to dry for about 15 minutes, then remove the T-Pins and pivot the aileron up and down several times to free up the
hinges. When done, repeat the previous procedures to hinge the second aileron to the other wing panel.
IMPORTANT Check the integrity of the hinges after the C/A fully cures by gently pulling on the ailerons. If one or more hinges
feels loose, apply more C/A to the hinge(s) and allow it to completely cure. The last thing you want is for a hinge to come loose
during ight.
IMPORTANT Do not hinge the aileron too tightly against the trailing edge of the wing panel. There needs to be a slight hinge
gap (no more than the width of a T-Pin), so that the aileron can pivot far enough to achieve the suggested control throws.
STEP 2: INSTALLING THE AILERON SERVOS
qCut away the covering material from over both the aileron servo mounting
hole and the aileron servo lead exit hole in the bottom of one wing panel. The
servo mounting hole is located 6-3/4" (171mm) out from the root end of the
wing panel and 4-1/4" (108mm) in front of the aileron hinge line. The servo
lead exit hole is located on the root end of the wing panel, 4-1/2" (114mm)
in front of the trailing edge.
IMPORTANT The servo output shaft should be toward the trailing
edge of the wing panel.
qRun the servo lead through the wing panel and out the servo lead exit hole.
qInstall the aileron servo into the mounting hole, making sure to drill 1/16"
(1.6mm) diameter pilot holes for the mounting screws, then repeat the previous
procedures to install the second aileron servo into the other wing panel.

Page 10
STEP 3: ALIGNING THE WING PANELS
qCut away the excess covering material that overlaps onto the root ribs
of each wing panel, leaving about 1/16" (1.6mm) overlapped so it does not
pull away.
IMPORTANT It's very important to the integrity of the wing center-
section joint that you remove as much covering material from the root ribs
as possible. Do not omit this procedure or the wing center-section joint
may fail during ight.
qLocate and draw a vertical centerline on one side of the wing joiner.
IMPORTANT The wing joiner is straight. There is no top or bottom.
q Test-t the wing joiner into each wing panel. It should slide easily into
each wing panel, up to the centerline you drew.
IMPORTANT When the wing joiner is installed, it should not t tightly
into the wing panels. It should actually be slightly loose. This will ensure
that when you glue the wing joiner into place, epoxy can get into the joints
between the wing joiner and the wing joiner mounting box. This will ensure
the strongest joint possible.
+ If the wing joiner does not t properly, use 220 grit sandpaper with a sanding block to lightly sand the wing joiner until you are
satised with the t.
qCarefully slide both wing panels together with the wing joiner temporarily
installed (without using glue).
q While holding the two wing panels together rmly, make sure that the wing panels are lined up at both the leading and trailing
edges, then look carefully at the center-section joint: the wing panels should t together tightly with few or no gaps in the joint.
IMPORTANT If the wing panels do not t together properly, remove the wing joiner and use 220 grit sandpaper with a sanding
block to lightly sand the edges and tips of the wing joiner until you are satised with the t. Remember, when the wing panels are
pushed together, there should be few or no gaps in the center-section joint.
STEP 4: JOINING THE WING PANELS
q When satised with the t and alignment, pull the wing panels apart and
remove the wing joiner.
q Apply a strip of masking tape to the top and bottom edges of the root rib
on each wing panel.
+The masking tape will prevent excess epoxy from getting onto the wing
panels when you join them.

Page 11
q Slide the wing joiner into the wing panel up to the centerline mark, then quickly remove any excess epoxy, using a paper towel
and rubbing alcohol, and allow the epoxy to set up before proceeding.
q After the epoxy has set up, test-t both wing panels together again to double-check that they still t together properly, then apply
a thin layer to the exposed half of the wing joiner, the inside of the wing joiner box in the second wing panel, and the entire surface
of BOTH root ribs. Make sure to use enough epoxy to ll any gaps.
q Working with only one wing panel for now, apply a thin layer of 30 minute
epoxy inside the wing joiner mounting box and to only half of the wing joiner.
Make sure to cover the top and bottom, as well as the sides, and use enough
epoxy to ll any gaps.
WARNING Use only 30 or 45 minute epoxy to install the wing joiner
and to join the wing panels together. Do not use 5 minute epoxy. It

qSlide the two wing panels together and realign them. Quickly wipe away
any excess epoxy, using a paper towel and rubbing alcohol, and use pieces of
masking tape to hold the two wing panels aligned until the epoxy fully cures.
IMPORTANT It is of the utmost importance to the integrity of the wing
center-section joint that you apply a generous amount of epoxy to both
root ribs and the wing joiner. Not using enough epoxy can result in wing
failure during ight.
STEP 5: CHECKING THE WING CENTER-SECTION JOINT
qOnce the epoxy has fully cured, remove the masking tape and double-check the center-section joint. If any gaps are present, mix
a small quantity of 30 minute epoxy and carefully ll any remaining gaps.
IMPORTANT Do not omit this procedure. The wing panels should t together tightly, but it's possible to have some small gaps
that appear after the epoxy has cured. To make the wing center-section joint as strong as possible, it's important to ll any gaps.

qCut away the covering material from over the top and bottom of the two
predrilled wing-screw mounting holes in the trailing edge of the wing. The
holes are located 3/4" (19mm) in front of the trailing edge and 3/4" (19mm)
out from the center-section joint.
STEP 1: INSTALLING THE WING-SCREW DOUBLER

Page 12
qCut away the covering material from over the predrilled holes in the wing-
screw doubler.
qPlace the wing-screw doubler onto the top of the wing and align the predrilled
holes in the wing-screw doubler with the predrilled holes in the wing.
qWhile holding the wing-screw doubler in place, draw an outline around it
onto the wing.
qCut away the covering material from inside the outline you drew, then
glue the wing-screw doubler to the wing.
STEP 2: MOUNTING THE WING
qApply a couple of drops of thin C/A into each threaded wing-screw mounting
hole in the fuselage and allow the C/A to fully cure before proceeding.
IMPORTANT The C/A will soak into the plywood, strengthening the
threads. Do not omit this procedure.
qPlace the wing into the wing saddle, push it forward completely, then push
the trailing edge down into place.
qAlign the holes in the wing with the threaded holes in the wing mounting
block inside the fuselage.
qSecure the wing into place, using two wing mounting screws.
+Don't overtighten the screws. You don't want to crush the wing or break
the screws off.

qRemove the elevator from the stabilizer and set it aside for now.
qCut away the covering material from over the top and bottom of the slot
in the middle of the stabilizer.
qMeasure and draw a centerline on the trailing edge of the stabilizer.
qMeasure and draw a centerline on the bottom of the stabilizer mounting
platform on the fuselage.
qSet the stabilizer onto the stabilizer mounting platform, then line up the
centerline you drew on the stabilizer with the centerline you drew on the
fuselage.
qWith the two centerline marks lined up and the trailing edge of the stabilizer
even with the back edge of the fuselage, hold only the trailing edge of the
stabilizer in position, using a T-Pin.
IMPORTANT The front of the stabilizer should be able to pivot from side to side and the back should stay rmly in place and
aligned. The trailing edge should not be allowed to move from side to side.

Page 14
qWith the wing mounted to the fuselage, use a ruler to measure the distance
between the tips of the stabilizer and the tips of the wing. Pivot the front of
the stabilizer until both of these measurements are equal.
+When both of these measurements are equal, you're assured that the
stabilizer is square to the wing.
q When you're satised that the stabilizer is square to the wing, use a T-Pin
to hold the front of the stabilizer rmly in place and aligned.
qLook from the front of the airplane at both the wing and the stabilizer.
When aligned properly, the stabilizer should be parallel to the wing. If the
stabilizer is not parallel to the wing, you'll need to remove the stabilizer and
sand down the higher side of the stabilizer mounting platform until you're
satised with the alignment.

q Once you're satised with the alignment, draw a line on each side of the
bottom of the stabilizer where it meets the fuselage.
WARNING When cutting through the covering to remove it in the next procedure, cut with only enough pressure to cut through
only the covering itself. Cutting down into the balsa structure could weaken the stabilizer and cause it to fail during ight.
qRemove the stabilizer from the fuselage, then carefully cut away the
covering material from inside the lines you drew.
PRO TIP Use a heat-sealing iron to adhere the covering material down
where you cut it. This will prevent it from loosening up and wrinkling.
qApply a generous amount of 30 minute epoxy to the gluing surfaces on both the stabilizer and the stabilizer mounting platform.
qSet the stabilizer into place and realign it, double-checking all of your measurements once more before the epoxy sets up. Quickly
remove any excess epoxy and use T-Pins to hold the stabilizer in place and aligned until the epoxy has fully cured.
q After the epoxy has fully cured, look closely at the glue joint. If there are any gaps between the stabilizer and the fuselage, ll
them using 30 minute epoxy for added strength.

Page 15
STEP 3: HINGING THE ELEVATOR
qHinge the elevator to the stabilizer, using the same techniques that you
used to hinge the ailerons to the wing panels. Make sure that the tips of the
elevator are even with the tips of the stabilizer.
IMPORTANT Remember, use a T-Pin pushed through each hinge to
set the correct hinge gap.
IMPORTANT After allowing the C/A to fully cure, pull on the elevator to check the integrity of the hinges. Apply more C/A to
the hinge(s) if necessary.

qCut away the covering material from below both the lines that you drew
on the stabilizer and from the base of the stabilizer, too.
qCut away the covering material from inside the outline that you drew on
top of the fuselage.
qCut away the covering material from over the stabilizer mounting slot in
the top of the fuselage. The mounting slot begins 5/16" (8mm) in front of the
horizontal stabilizer and is 2-1/4" (57mm) long and 1/4" (6mm) wide.
qGlue the stabilizer into place, using a generous amount of 30 minute epoxy.
IMPORTANT It's important that the vertical stabilizer be perpendicular to the horizontal stabilizer. Double-check this while the
epoxy is setting up and curing.
qPush the stabilizer down into the mounting slot, then draw a line on each
side of the stabilizer where it meets the top of the fuselage. Draw an outline
onto the fuselage around the base of the stabilizer, too.
qGlue one triangle support between each side of the stabilizer and the top
of the fuselage. Again, make sure to cut away the covering material from
the gluing surfaces to ensure a strong glue joint.

Page 16
STEP 1: INSTALLING THE TAIL SKID
STEP 5: HINGING THE RUDDER
qHinge the rudder to the stabilizer, using the same techniques that you
used to hinge the elevator to the horizontal stabilizer. Make sure that the
tip of the rudder is even with the tip of the stabilizer and that the base of the
rudder does not rub against the top of the horizontal stabilizer.
IMPORTANT Remember, use a T-Pin pushed through each hinge to
set the correct hinge gap.
IMPORTANT After allowing the C/A to fully cure, pull on the rudder to check the integrity of the hinges. Apply more C/A to the
hinge(s) if necessary.

STEP 1: INSTALLING THE ENGINE MOUNTING BEAMS
IMPORTANT The following procedures outline the installation of a two-stroke engine. Installing a four-stroke engine is the
same, although you may need to install the engine further out on the engine mounting beams to accommodate the carburetor.
qUse a dab of thick C/A to temporarily glue the engine mounting beams
to your engine, making sure that both engine mounting beams are straight
and even.
PRO TIP Mount the engine as far forward as possible to ensure that the
engine mounting beams remain square.
q Line up the engine mounting beams with the precut slots in the rewall
and temporarily install the four M3 x 18mm machine screws, four M3 at
washers and four M3 blind nuts.
qCarefully center the engine mounting beams over the precut slots and
rmly tighten the four machine screws to draw the blind nuts into the back
of the rewall.
STEP 2: INSTALLING THE ENGINE
qInstall your spinner backplate (not included) onto your engine's crankshaft,
using the propeller washer and nut included with your engine.
qMeasure the distance from the front of the fuselage side (not the
firewall) to the back of the spinner backplate. Adjust the depth of the
engine so that the measurement is 4-1/8" (105mm).
qSlide one wheel onto each axle, then secure the wheels into place, using
two wheel collars and two M3 x 5mm machine screws.
+ Tighten the machine screws rmly, then double-check that both wheels
spin freely.
IMPORTANT The recess in each wheel should be toward the inside.

Page 19
qMark the locations of the engine mounting holes onto the engine mounting
beams.
qRemove the engine and drill 5/64" (2mm) diameter pilot holes through
the engine mounting beams at the marks you drew, then enlarge the pilot

STEP 1: INSTALLING THE THROTTLE SERVO
q Install the rubber grommets and brass collets onto your throttle servo, making sure to install the collets with the anges toward
the bottom of the servo.
qInstall the throttle servo into the plywood servo tray, making sure to drill
1/16" (1.6mm) diameter pilot holes for the servo mounting screws.
IMPORTANT Note the orientation of the servo. When installed, the
servo output shaft must be toward the back of the fuselage and the servo
should be pushed up against the right side of the servo tray.

Page 20
STEP 2: INSTALLING THE THROTTLE PUSHROD WIRE
qRemove the throttle arm from your engine and install the Z-Bend in the
pushrod wire into the outermost hole in the throttle arm.
+You may need to enlarge the hole in your engine's throttle arm, using a
5/64" (2mm) diameter drill bit, to accommodate the pushrod wire.
q Slide the pushrod wire through the predrilled hole in the rewall and the
forward bulkhead, then reinstall the throttle arm onto your engine. You will
need to make two bends in the pushrod wire so that it will line up with the
throttle arm and prevent binding.
qOpen and close the carburetor several times to ensure that the pushrod
wire does not bind.
STEP 3: INSTALLING THE ADJUSTABLE PUSHROD CONNECTOR
qCut away all but one arm from a "4-point" servo horn.
qEnlarge the hole in the servo arm that is 9/16" (14mm) out from the center
of the servo horn, using a 5/64" (2mm) diameter drill bit.
qInstall the adjustable pushrod connector onto the servo arm, making sure
not to tighten the nut too tightly. You don't want the pushrod connector loose,
but it should be able to rotate without binding.
IMPORTANT To prevent the nut from loosening during ight, apply a
drop of thin C/A to it. Allow the C/A to fully cure before proceeding.
qConnect your radio system and check that the throttle servo output shaft is rotating in the correct direction, then position the throttle
control stick and the throttle trim lever to their lowest positions.
qCut away the excess pushrod wire, then install and tighten the servo horn retaining screw to hold the servo horn securely to
the servo.
qOpen and close the throttle several times to ensure that the carburetor opens and closes completely and without binding. You
may need to adjust your transmitter EPA settings to achieve perfect settings.
qSlide the adjustable pushrod connector assembly onto the pushrod wire,
then install the servo horn onto the servo, making sure that it's angled
approximately 30 degrees from center.
qWhile holding the carburetor fully closed (open for four-stroke engines),
install and tighten the machine screw in the adjustable pushrod connector.
IMPORTANT You will need to make two bends in the pushrod wire so
that it will line up with the pushrod connector and prevent binding.
