Thank you for purchasing the latest version of the Flyzone L-39. A more powerful motor is now included which will enable speeds
approaching 100mph! The L-39 flies like it’s on rails and the vibrant color scheme looks great as it cuts across a blue horizon. Durable EPO
foam construction resists damage from bumpy landings and repairs easily with regular CA glue. A display stand is included to show off your
model on your trophy shelf when it’s not busy carving up the skies above your flying field!

For the latest technical updates or manual corrections to the L-39 visit the Flyzone web site at www.flyzoneplanes.com. Open the “Airplanes”
link, then select the L-39. 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.

WARNING!

The L-39 requires advanced flying skills and is not suitable for beginning or intermediate pilots. It reaches speeds of over
90 mph (145 km/h) and should be flown only at the flying site of an AMA-chartered club. Because it can quickly disappear
from sight, pilots should remain focused on the plane at all times.

DECISIONS YOU MUST MAKE

This is a partial list of items required to finish the L-39 EDF that may require planning or decision making before starting to build.
Order numbers are provided in parentheses.

Radio Equipment

The L-39 EDF requires a 3+ channel transmitter and a receiver. If you already have a transmitter you are going to use to fly the
L-39, you can get the receiver separately:

❍ Futaba 617FS FASST 2.4 GHz receiver [FUTL7637]

OR

❍ Tactic TR624 6-Channel 2.4GHz SLT Receiver

Using the Tactic AnyLink2 2.4GHz Universal Radio Adapter (TACJ2005) will make virtually any transmitter with a trainer port
compatIble with the above mentioned Tactic receiver. Optional cables available through your hobby supplier may be necessary
to use the AnyLink2 with some transmitters.

A lithium-polymer battery pack and suitable charger are also required (batteries larger than the recommended Great Planes LiPo
may not fit in the battery compartment):

❍ Great Planes ElectriFly LiPo 4S 14.8V 2200mAh 30C (GPMP0862)
❍ Great Planes ElectriFly Triton EQ AC/DC Charger (GPMM3155)

ADDITIONAL ITEMS REQUIRED

Adhesives and Building Supplies

Foam safe CA glue and 30-minute epoxy are used in the
assembly of the L-39. Order numbers are provided below:

❍ Great Planes Pro™ Epoxy 30-Minute Formula 4 oz.

(GPMR6043)

❍ Great Planes Pro Foam Safe CA- Thick Glue 1 oz.

(GPMR6072) (used for display stand assembly)

❍ Denatured alcohol (for epoxy clean up)

This manual also refers to using a #60 [.040"] and a 3/64"
[1.2mm] drill bit:

❍ Hobbico® Pin Vise 1/16 Collet w/6 Bits (HCAR0696)

Optional Supplies and Tools

Here is a list of items that will help you build the L-39:

❍ CA debonder (GPMR6039)
❍ Epoxy brushes (6, GPMR8060)
❍ Mixing sticks (50, GPMR8055)
❍ Mixing cups (GPMR8056)
❍ CG Machine™ (GPMR2400)
❍ Hobbico Flexible 18" Ruler Stainless Steel (HCAR0460)

BEFORE YOU BEGIN

Before building the model, please follow the break-in

❏

instructions found on page 10 of this manual.

ASSEMBLE THE AIRPLANE

1. Attach a 6" [152mm] servo extension to the ESC receiver

❏

lead. Secure the extension with tape or heatshrink tubing (not
included).

3. Coat the wing saddle on the fuselage with 30-minute epoxy. Insert the aileron servo wires through the hole in the fuse and

❏

into the radio compartment. Place the wing onto the saddle by fitting the alignment keys on the top of the wing into the mating
cutouts in the wing saddle. Tape the wing to the fuse while the epoxy cures or place a weight on the top of the fuse (recommended)
to press it against the wing (prop the plane up between the aileron control horns so it doesn’t damage the aileron hinges). If using
tape, avoid damaging the paint by first lining the outside of the model with sheets of paper or something similar. Wrap the tape
tightly around the paper instead of directly onto the model.

2. Route the motor wires and ESC lead along the underside

❏

of the fuselage and through the hole into the radio compartment.
Trace around the servo extension connector as it fits in the wire
channel. Cut away the foam inside your traced lines so that the
connector sits flush inside the channel. A small piece of double­sided tape (not included) will hold it in place.

4. The vertical fin and horizontal stabilizer are keyed to fit together and it is recommended that they be glued in place at

❏

the same time. Coat with epoxy the key on the bottom of the fin, the slot in the horizontal stabilizer, and the stab saddle on the
fuselage. Do not put epoxy on the front of the fin that fits into the ducted fan access hatch. The hatch must remain removable.

3

5. Position the parts onto the fuselage, making sure that the vertical fin is being glued square to the horizontal stabilizer. The

❏

parts can be taped in place while the epoxy cures.

6. Insert the 90° bend (at the aft end) into the outer hole of the elevator control horn. Secure it using the 90° pushrod connector.

❏

Make a small, upward bend in the elevator pushrod as shown. Fit the pushrod through the screw-lock connector and attach the
servo arm to the servo using the servo arm screw. Use your radio system to center the elevator servo. Position the elevators in
the neutral position and securely tighten the screw-lock connector against the pushrod.

7. Attach a dual servo extension to the aileron servo leads.

❏

Connect the dual servo extension, elevator servo lead and ESC
to the receiver. Bundle the excess servo leads out of the way
of the elevator servo and use the included self-adhesive hook
and loop material to secure the receiver to the side of the radio
compartment as shown.

8. Apply the hook side of the included self-adhesive hook

❏

and loop material in the radio compartment (depending on the
battery height, you may need to attach the hook and loop on
the side as shown). Brushing on a thin coat of epoxy and letting
it cure before attaching the hook material will help it adhere to
the foam. Apply the loop side to your battery pack.
