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 firewall has been modified 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 flies great, with the features

you want, in a plane that is affordable and fun. Put some Magic in your flying with the Magic V2 from Model Tech.

Page 9 q Working 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.
Page 10 steP 3: aLiGNiNG tHe WiNG PaNeLs q Cut 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.
Page 11: Wing Mounting
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 fill any gaps.
Page 12 q Cut away the covering material from over the predrilled holes in the wing- screw doubler. q Place 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. q While holding the wing-screw doubler in place, draw an outline around it onto the wing.

Page 14 q With 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.
Page 15 steP 3: HiNGiNG tHe eLevator q Hinge 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.
Page 16: Tail Skid Installation
steP 5: HiNGiNG tHe ruDDer q Hinge the rudder to the stabilizer, using the same techniques that you used to hinge the elevator to the horizontal stabilizer.

q Mark the locations of the engine mounting holes onto the engine mounting beams. q Remove the engine and drill 5/64" (2mm) diameter pilot holes through the engine mounting beams at the marks you drew, then enlarge the pilot holes, using a 1/8" (3mm) diameter drill bit. IMPORTANT Be careful that you drill the holes straight down and not at an angle.
Page 20 steP 2: iNstaLLiNG tHe tHrottLe PusHroD Wire q Remove 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"...

q With the stopper assembly installed, double-check to make sure that the clunk can move freely inside the fuel tank. Ideally, the clunk should be about 1/4" (6mm) in front of the back of the fuel tank. This will ensure that the clunk can't get stuck in the fuel tank during flight.
Page 23 steP 1: iNstaLLiNG tHe eLevator servo IMPORTANT Remember, you must use a low-profile elevator servo. A standard servo is too tall and will hit the bottom of the fuselage. q Install the rubber grommets and brass collets onto your elevator servo, making sure to install the collets with the flanges toward the bottom of the servo.
Page 24 steP 3: iNstaLLiNG tHe eLevator PuLL-PuLL CaBLes q Using a pair of wire cutters, carefully cut the stranded pull-pull cable exactly in half. q Slide one crimp collet, non-flanged side first, over one end of one cable. IMPORTANT If the ends of the cable begin to unravel, use your fingers to twist the ends back into shape. q While holding the crimp collet in place so it doesn't slide off, carefully thread the same end of the cable through the hole in one threaded coupler.
Page 25: Rudder Control System Installation
q Use a couple of pieces of masking tape, taped between the elevator and the stabilizer, to hold the elevator centered. q Center the elevator servo, then attach the cable from the left side cable guide to the Z-Bend coupler on the left side of the servo arm, then attach the length of cable from the right side cable guide to the Z-Bend coupler on the right side of the servo arm, using the same techniques that you used to attach the threaded couplers.
Page 26 steP 2: iNstaLLiNG tHe ruDDer CoNtroL HorNs q Cut away the covering material from over the two rudder cable exit slots in the top of the fuselage. One slot is located on each side of the vertical stabilizer, 1/8" (3mm) out from the edge of the triangle supports and 2-1/2" (64mm) in front of the rudder hinge line.
Page 27: Aileron Control System Installation
q Install the Z-Bend in each of the two Z-Bend couplers into the hole in the servo arms that you enlarged, then attach the cables to the Z-Bend couplers, using the same techniques that you used to install the elevator cables to the Z-Bend couplers.
Page 28: Final Assembly
q Install the 90º bend in the pushrod wire into the hole that you enlarged in the servo arm, using one snap-keeper. The pushrod wire should be orientated on top of the servo arm. q Center the aileron servo, then install the servo horn onto the servo, making sure that the servo horn is centered and pointing out toward the wing tip.
Page 29 IMPORTANT The hatch cover is provided for electric fliers to access their LiPO motor battery. If you're using a glow engine in your Magic V2 aircraft, we strongly suggest gluing the hatch cover securely to the fuselage. If you do decide to use the hatch cover, please make sure not to mount anything directly to it (like your receiver or battery).
Page 30: C/G And Balancing
C/G aND BaLaNCiNG IMPORTANT It is critical that your airplane be balanced correctly. Incorrectly balancing your airplane can cause your airplane to lose control and crash! BALANCE POINT (C/G): 4-1/2" (114MM) BAck FRoM The leADIng eDge oF The WIng, MeAsuReD AT The FuselAge sIDes. IMPORTANT Balance the airplane with the fuel tank empty.
Page 31: Preflight Check And Safety
eXPoNeNtiaL Expo, as it's more commonly referred to, softens the control feel around neutral. This is especially helpful when flying an airplane that uses a lot of control throw. Softening the neutral point makes the airplane fly more smoothly and makes it more likely that you won't over-control.
Page 32: Electric Conversion Instructions
eLeCtriC CoNversioN iNstruCtioNs IMPORTANT This section describes the installation of a brushless Outrunner power system that is mounted directly to the firewall. This power system features the KMS Quantum 4120/05 Brushless Outrunner motor, Castle Creations Phoenix 60 Brushless ESC and the Impulse Power 4C 4000mAH LiPO battery. These instructions are general in nature, but should be similar for most brushless Outrunner power systems.
Page 33 q After installing your motor, drill a 1/4" (6mm) tall slot in the bottom of the firewall to run the motor leads through. steP 2: iNstaLLiNG tHe eLeCtroNiC sPeeD CoNtroL q Mount your ESC to the side of the fuselage using a piece of double-sided foam tape (not included).
