CAUTION.
A Remote Control Model Aircraft is not a toy. It is a flying model that functions much like a full size airplane. If
you do not assemble and operate this product properly you can cause injury to yourself and others and damage
property. DO NOT FLY this model if you are not qualified.
You are ultimately responsible for the mechanical, aeronautical and electrical integrity of this model and it’s struc-

all components before and after each flight. Do not fly until it’s right!
INTRODUCTION
Thank you for purchasing a VMAR product. VMAR Manufacturing is committed to delivering superior value to the
RC modeler. Your new EDGE - 540T is the market leader in features, ease of use and flexibility. Please review
these instructions before beginning the simple assembly procedure.
We’ve used metric measurements throughout these instructions. We know that some of you like metric while oth-
ers think that furlongs per fortnight makes a nifty velocity indicator. If you are in the furlong camp, bear with us….
It’s not a big deal…3 millimeters is stated as 3mm and 3mm is about 1/8 of an inch. Fire up your calculator and
you will find that 25.4 mm makes an inch. In places where you have to actually set up something according to a
recommended measurement, we’ve listed an approximate imperial measurement in inches in brackets.
Whenever we’ve used the directional terms left or right , they are with respect to the model when viewed as you
would when sitting in the cockpit…that is when viewed from the back looking forward.

CHECK OUT THE CONTENTS.
You’ve taken the lid off the box and grabbed the instruction booklet…you are about 6-8 hours away being ready to
go flying! Now is the time to look over what’s in the box. Please go through the contents and make sure nothing
has been damaged in shipping. Damage or missing components must be reported to your vendor BEFORE any
assembly begins. Please DO NOT START if something is damaged or missing. As you can imagine, once you join
the wing halves or install your radio or engine your options for returns are very limited. Your vendor will not be able
to provide you with exchanges or replacements of parts that have been assembled. DO NOT START UNLESS IT’S
RIGHT!

INSTALLING THE PLUG-IN WING OF THE EDGE 540T
To install the plug-in wing of the EDGE - 540T to the
fuselage you will need the following parts.
- 1 front aluminum tube spar joiner 20 inch (510mm)
long and 2/3 inch (16mm) diameter
- 1 rear aluminum tube spar joiner 20 inch (510mm) long
and 2/3 inch (16mm) diameter
- 2 aluminum collars
- 2 steel nuts (4mm)
Stage 1
Step 1. Turn over the fuselage, by
remove screws and push slightly
to the other end of the hatch cover
to take out the cover (as shown)
Step 2. Insert the front wing spar
joiner and then the rear spar joiner (as shown 1.3 )
Step 3. Remove the nut and aluminum collar from the wing root
(opposite end of the wing tip)
Step 4. Carefull insert the 2 wing
spar joiner tube into the wing.
Notice that you will not forget to
acess the wiring harness of the
aileron through the hole (as
shown)
Step 5. Repeated this procedure
to another side of wing

FITTING AILERON SERVOS
To install the aileron servos into the wing you will need the
following items :
- Servos
- Servos mounting screws and grommets as supplied with
servos.
- Servo control arms as supplied with the servos.
- Two aileron control rod assemblies supplied with the kit.
The assemblies consist of a metal rod with a plastic clevis
screwed onto both ends.
- Low tack masking tape.
- 2 aileron control horn assemblies
2.1 Prepare the servos by fitting the rubber
grommets & ferrules supplied with your radio
Stage 2
Carefully remove the white cover plates from the aileron
servo cavities. Ensure you know which cover plate is for the
right wing and which is for the left. Remove the white cover
plates and retain the mounting screws. Notice that there are
wooden servo rails pre-installed into each servo cavity end.
Locate the wiring harness tubes that are protruding slightly
into each aileron servo cavity. The tube can be moved slightly at this point. Check out the other end of each tube for a
clean position and then using C/A glue secure the wiring harness tubes at the aileron servo cavity end.
Install a servo in each aileron servo cavity and connect the
servo wire to the servo extension wires and run the extension
wires through wiring harness tubes to the centre of the wing
Install the aileron control horns
2.3 Aileron servos mount 2.4 Srew servo in position 2.5 Install aileron control horn
Aileron servos cavity
2.2 Aileron servos location
Step 1 Consult your radio instruction manual and center each aileron servos by plugging it into the aileron channel
in the receiver. Turn on the transmitter and then the receiver. Center the aileron trim lever on the transmitter.
Remove the servo arm mounting screw and the servo arm.
Step 2 Mount the servo arm back on the servo. Position the arm to be parallel with the back edge of the wing. Screw
the arm into place with the servo arm mounting screw supplied with the servo.
Locate the two aileron control rods in the hardware bag. Ensure the clevises are screwed well onto the threaded
portion of the rod. Rotate and tug aggressively on the clevises and ensure that they are not loose on the rods.
Tape the ailerons into their neutral position so that they are even with the trailing edge of the wing and not pointing
either up or down.
Stage 3

Step 3 Ensure that the aileron control horns are screwed onto the threaded aileron control horn bolts and that both
control horns are in approximately the same place on their respective bolts.
Step 4 Connect the aileron servo rods to the aileron control horns. If one of the two clevises on each rod has a
metal pin or screw, attach that clevis to the servo output arm.
Step 5 Connect the other clevis to the servo output arm
Step 6 Remove the masking tape holding the ailerons.
Step 7 In the case of computer radios the servos together by connecting them to the appropiate receiver channel
. In the case of analog radios couple the servos together using a Y harness
Step 8 Turn on your radio and activate the ailerons, using the aileron stick and ensure a smooth full motion can be
achieved.
Step 9 With the wing top side up and viewed from the back, ensure that moving the transmitter aileron stick to the
left raises the left aileron and lowers the right aileron. Movement of the stick to the left will roll the aircraft to the left.
(Counterclockwise roll of the wing when viewed from the back ).
Step 10 With the wing top side up and viewed from the back, ensure that moving the transmitter aileron stick to the
right raises the right aileron and lowers the left aileron. Movement of the stick to the right will roll the aircraft to the
right.
