Introduction
The classic aerobatic plane Zlin 50L is used from the Flying Bulls Aerobatic Team for a long time. On a lot of ight
shows and events, the Flying Bulls Aerobatic team demonstrated amazing gures and stunning maneuvers. The
Flitework Zlin 50-M is a very powerful and stable ying replica of this famous plane.
Enjoy at http://www.yingbulls.cz/start_e.html
Attention please!
Remote controlled model planes are not a toy! For assembling, ying and servicing such models, you need a high
grade of technical comprehension and liability.
Careless assembling and operation may cause personal and material damage.
Because the Flitework GmbH has no inuence on assembly, RC installation, operation and servicing of the ight
device, any liability is rejected under explicit advice to these dangers.

Flitework quatily
We, as the kit manufacturer, provide you with a top quality kit and instructions, but ultimately the quality and yability of your
nished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed
model and no representations are expressed or implied as to the performance or safety of your completed model.
SAFETY PRECAUTIONS
1. Your Zlin Z-50L 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 Zlin Z-50L 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 a
unsafe or unyable model. In a few cases the instructions may
dier 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 rst-class
condition and a correctly sized engine and components (fuel
tank, wheels, etc.) throughout the building process.
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
ight 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 already an experienced R/C pilot, you should
y the model only with the help of a competent, experienced
R/C pilot.
8. While this kit has been ight tested to exceed normal use,
if the plane will be used for extremly hight stress ying, such
as racing, or if an engine larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the hight stress points and/or substituting hardware
more suitable for the increased stress.
9. WARNING: The cowl and wheel pants included in this kit
are made of berglass, the bers of which may cause eye,
skin and respiratory tract irritation. Never blow into a part to
remove berglass 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 berglas parts.
Vacuum the parts and work area thoroughly after working
with berglass parts.

BALANCE THE MODEL (C.G.)
More than any other factor, the C.G. (balance point) can
have the greatest eect on how a model ies and may
determine whether or not your rst ight will be successful.
If you value this model and wish to enjoy it for many ights,
DO NOT OVERLOOK THIS IMPORTANT PROCEDURE. A
model that is not properly balanced will be unstable and
possibly unyable.
At this stage the model should be in ready-to-y condition
with all of the systems in place including the engine, landing
gear, covering and the radio system.
1. Use a felt-tip pen or 1/8"-wide tape to accurately mark
the C.G. on the top of the wing. The C.G. is located 118
mm (4.6 ") back from the leading edge of the wing.
2. With the wing attached to the fuselage, all parts of
the model installed (ready to y) and with batteries in
position, 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 battery
pack and/or receiver must be shifted forward or weight
must be added to the nose to balance. If the nose drops,
the model is“nose heavy” and the battery pack and/or
receiver must be shifted aft or weight must be added to
the tail to balance. If possible, relocate the battery pack
and receiver to minimize or eliminate any additional
ballast required. If additional weight is required, nose
weight may be easily added by using a “spinner weight”
(GPMQ4645 for the 1 oz. weight, or GPMQ4646 for the
2 oz. weight). If spinner weight is not practical or is not
enough, use Great Planes (GPMQ4485)“stick-on”lead. A
good place to add stick-on nose weight is to the rewall
(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 rewall 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.
GET THE MODEL READY TO FLY
CHECK THE CONTROL DIRECTIONS
1. Turn on the transmitter and receiver 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 clevises on the pushrods to center the control surfaces.

3. Make certain that the control surfaces and the carburetor
respond in the correct direction as shown in the diagram. If any
of the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have remained
centered. Adjust if necessary.

PREFLIGHT
IDENTIFY YOUR MODEL
No matter if you y at an AMA sanctioned R/C club site or
if you y 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 ying
sites and AMA sanctioned ying events. Fill out the identi-
cation tag on the decal sheet and place it on or inside your
model.
CHARGE THE BATTERIES
Follow the battery charging instructions that came with your
radio control system to charge the batteries. You should always
charge your transmitter and receiver batteries the night before
you go ying and at other times as recommended by the radio
manufacturer.
NOTE: Checking the condition of your receiver battery pack is
highly recommended. All battery packs, whether it's a trusty
pack you've just taken out of another model, or a new battery
pack you just purchased, should be cycled, noting the discharge
capacity. Oftentimes, a weak battery pack can be identied (and
a valuable model saved!) by comparing its actual capacity to its
rated capacity. Refer to the instructions and recommendations
that come with your cycler. If you don't own a battery cycler,
perhaps you can have a friend cycle your pack and note the
capacity for you. gemessenen. Hier können große Unterschiede
auftreten.
Note: Do not rely upon the adhesive on the back of the
lead weight to permanently hold it in place. Over time, the
adhesive may softern and cause the weight to fall o. Use
#2 sheet metal screws, RTV silicone or epoxy to permanently
hold the weight in place.
4. IMPORTANT: If you found it necessary to add any
weight, recheck the C.G. after the weight has been
installed.
BALANCE THE MODEL LATERALLY
  1. With the wing level, have an assistant help you lift
the model by the engine propeller shaft and the bottom of the
fuse under the TE of the n. 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.
SET THE CONTROL THROWS
Use 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 have dual rates, we recommend setting
the throws at the low rate settings.
NOTE: The throws are measured at the widest part of the
elevators, rudder and ailerons.

BALANCE PROPELLERS
Carefully balance your propeller and spare propellers before
you y. An unbalanced prop can be the single most signicant
cause of vibration that can damage your model. Not only will
engine mounting screws and bolts loosen, possibly with
disastrous eect, but vibration may also damage your radio
receiver and battery. Vibration can also cause your fuel to
foam, which will, in turn, cause your engine to run hot or quit
We use a Top Flite® Precision Magnetic Prop Balancer™
(TOPQ5700) in the workshop and keep a Great Planes Finger-
tip Prop Balancer (GPMQ5000) in our ight box.
RANGE CHECK
Ground check the operational range of your radio before the
rst ight of the day. With the transmitter antenna collapsed
and the receiver and transmitter on, you should be able to
walk at least 100 feet 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 surfaces are
doing. Repeat this test with the engine running at various
speeds with an assistant holding the model, using hand sig-
nals to show you what is happening. If the control surfaces do
not respond correctly, do not y! Find and correct the problem
rst. Look for loose servo connections or broken wires, corro-
ded 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.
ENGINE SAFETY PRECAUTIONS
Failure to follow these safety precautions may result
in severe injury to yourself and others.
Get help from an experienced pilot when learning to
operate engines.
Use safety glasses when starting or running engines.
Do not run the engine in an area of loose gravel or sand;
the propeller may throw such material in your face or
eyes.
Keep your face and body as well as all spectators away
from the plane of rotation of the propeller as you start
and run the engine.
Keep these items away from the prop: loose clothing,
shirt 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 engine gets hot! Do not touch it during or right after
operation.
Do not use hands, ngers or any other body part to try to
stop the engine.
Do not throw anything into the propeller of a running
engine.
SAFETY CODE
GENERAL
1. I will not y my model aircraft in sanctioned events,
air shows, or model ying demonstrations until it has
been proven to be airworthy by having been previously
successfully ight tested.
2. I will not y my model aircraft higher than
approximately 400 feet within 3 miles of an airport
without notifying the airport operator. I will give right
of way to and avoid ying in the proximity of full scale
aircraft. Where necessary an observer shall be used
to supervise ying to avoid having models y in the
proximity of full scale aircraft.
3. Where established, I will abide by the safety rules for
the ying site I use and I will not willfully and deliberately
y my models in a careless, reckless and/or dangerous
manner.
7. I will not y my model unless it is identied with my
name and address or AMA number, on or in the model.
9. I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).
RADIO CONTROL
1. I will have completed a successful radio equipment
ground check before the rst ight of a new or repaired
model.
2. I will not y my model aircraft in the presence of
spectators until I become a qualied ier, unless assisted
by an experienced helper.
3. I will perform my initial turn after takeo away from the
pit or spectator areas and I will not thereafter y over pit
or spectator areas, unless beyond my control.
4. I will operate my model using only radio control
frequencies
currently allowed by the Federal Communications
Commission.

CHECK-LIST
During the last few moments of preparation your mind may
be elsewhere anticipating the excitement of the rst ight.
Because of this, you may be more likely to overlook certain
checks and procedures that should be performed before
the model is own. To help avoid this, a checklist is provided
to make sure these important areas are no overlooked.
Many are covered in the instruction manual, so where
appropriate, refer to the manual for complete instructions.
Be sure to check the items o as they are completed (that's
why it's called a check list!).
1. Check the C.G. according to the measurements
provided in the manual.
2. Be certain the battery and receiver are securely
mounted in the fuse. Simply stung them into place with
foam rubber is not sucient.
3. Extend your receiver antenna and make sure it has a
strain relief inside the fuselage to keep tension o the
solder joint inside the receiver.
4. Balance your model laterally as explained in the
instructions.
5. Use threadlocking compound to secure critical
fasteners such as the set screws that hold the wheel
axles to the struts, screws that hold the carburetor arm (if
applicable), screw-lock pushrod connectors, etc.
6. Add a drop of oil to the axles so the wheels will turn
freely.
7. Make sure all hinges are securely glued in place.
8. Reinforce holes for wood screws with thin CA where
appropriate (servo mounting screws, cowl mounting
screws, etc.).
9. Conrm that all controls operate in the correct direction
and the throws are set up according to the manual.
10. Make sure there are silicone retainers on all the
clevises and that all servo arms are secured to the servos
with the screws included with your radio.
11. Secure connections between servo wires and Y
connectors or servo extensions and the connection
between your battery pack and the on/o switch with
vinyl tape, heat shrink tubing or special clips suitable for
that purpose.
12. Make sure any servo extension cords you may have
used do not interfere with other systems (servo arms,
pushrods, etc.).
13. Balance your propeller (and spare propellers).
14. Tighten the propeller nut and spinner.
15. Place your name, address, AMA number and
telephone number on or inside your model.
16. If you wish to photograph your model, do so before
your rst ight.
17. Range check your radio when you get to the ying
eld.
Remember to think.
Have a ball!
But always stay in control and y in
a safe manner.
GOOD LUCK AND
GREAT FLYING!
