SAFETY PRECAUTIONS
1. Your Midi Edge540 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 Midi Edge 540 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 unyable model. In a few cases the instructions may
dier 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.
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

CHOOSING THE MOTOR SET
If you choose a motor for back mount like the motor from
speed motorset, you have to use the shorter motordome
which is attached as milling parts in the box of accessories.
The longer, just assembled motor dome is only for front
mounting of brushless motors with 28mm diameter.
WINGS ASSEMBLY
Glue the hinges into the slots in wing and aileron, using CA
or PVA glue. The glue should be very liquid for better glueing
results.
ENGLISH
Mount the aileron servo as shown in the picture with 2 screws.
Search the center position with servo tester or RC and attach
the servo lever parallel to the aileron.
During assembly, look for correct angles and position of the
aileron. If the aileron is in neutral position, the servo lever and
the linkage should include an angel of 90 degrees.

Screw the motor to the motor dome, using M3x8 countersunk
screws.
ENGLISH
Find the correct position of the cowling and x it with adhesive
tape. Drill two or three 1.2 mm holes through the cowling and
the wood below.
The propeller, not included in the kit should be balanced as
good as possible. Assemble prop and spinner. The best result
for balancing you can get, if you have the possibility to balance
the propeller together with the spinner.
Mount the propeller unit to the motor shaft with the 2 M3
setscrews. Lock with blue locking agent. You can make a little
at spot onto the motor shaft at the position of one setscrew.
So you can get more stability.
Mount the canopy with the attached 2 mm woodscrews. You
can reinforce the thread in the wood with super liquid CA glue.

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.
Use the attached velcro tape, to x the battery inside the body.
Fasten the battery, using Fliteworks battery tape.
To x the receiver, you can use double sided adhesive tape.

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.

BALANCE THE MODEL (C.G.)
More than any other factor, the C.G. (balance point) can
have the greatest eect 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 unyable.
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 65 mm
back from the leading edge of the wing.
ENGLISH
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.
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.
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.
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.

PREFLIGHT
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 identied (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.
Carefully balance your propeller and spare propellers before
you y. An unbalanced prop can be the single most signicant cause of vibration that can damage your model. Not only
will engine mounting screws and bolts loosen, possibly with
disastrous eect, 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 Fingertip 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 signals 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, 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.

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 stung them into place with
foam rubber is not sucient.
ENGLISH
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.
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.
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. Conrm 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).
GOOD LUCK AND
GREAT FLYING!
14. Tighten the propeller nut and spinner.
