NOTE : The throws are measured at the widest part of the elevator , rudder and aileron. Adjust the position of the pushrods
at the control/servo horns to control the amount of throw. You may also use the ATV’s if your transmitter has them but the
mechanical linkages should still be set so that the ATV’s are near 100% for best servo resolution.

25.1 Consult your radio manual for instructions
about hooking up your receiver battery, receiver and switch
harness.
25.2 Wrap the battery pack securely in foam suitable for RC
equipment and wrap the foam insulated pack in a plastic
bag or cling wrap.
25.3 Thread the battery pack connector back through from
beneath the fuel tank to the radio compartment by passing
the battery connector through an opening beside the fuel
tank.
25.4 Connect the battery connector to your radio system
according to the radio manual.
INSTALLING THE RECEIVER BATTERY
Stage 25
26.1 Consult your radio manual for instructions about hook-
ing up your receiver.
26.2 Plan where you are going to put the receiver with consideration for routing the antenna safely.
26.3 Wrap the receiver securely in foam suitable for RC
equipment and wrap the foam insulated receiver in a plastic bag or cling wrap.
26.4 Generally in the absence of specific instructions from
the radio manufacturer, it is recommended that the receiver should be placed where it is least likely to have impact
during a crash. Keep the battery pack and other heavy
loose items ahead of the receiver.
INSTALLING THE RECEIVER
Stage 26
27.1 Consult your radio manual for instructions about test-
ing and operating your radio system.
27.2 Pay particular attention to charging your radio system
batteries and range testing the system before and after
each flight.
27.3 Check that all controls are working correctly before
and after each flight.
COMFIRM RADIO OPERATION
Stage 27
The CG for your EXTRA - 330L is located at 120 - 130 mm
(4 3/4” to 5 1/4”) back from the leading edge of the wing
when the wing has been attached to the fuselage.
For the initial flight, the CG should be located at 4 3/4”
(120mm) back from the leading edge of the wing when
the wing has been attached to the fuselage.
The CG is measured with the engine, radio gear and all
other components installed but WITH NO FUEL IN THE
TANK.
Set up the CG as it will be when you fly it BUT WITH NO
FUEL IN THE TANK.
It is very important to have the CG correct. Flying your model
with the CG too far will likely lead to loss control and a crash.
If you discover that after you have assembled your model
and installed your radio and engine that the CG is incorrect
you must bring the CG to the correct location by doing the
following BEFORE FLYING :
- Move the battery pack fore or aft.
- Move other components fore or aft.
- Change engine to a lighter or heavier model.
- Add weight to the nose or tail. If adding it to the nose,
try to make it useful by going to a heavier duty engine
or adding a spinner with a heavy metal backing plate.
As a last resort, add stick on “dead” weight where
appropriate.
BALANCING THE AIRCRAFT.
Stage 28
29.1 Once you have confirmed that the CG is correct, you
should do a thorough review of the entire model before your
first flight. Check everything twice! Every hook up, every
coupling, everything! Do it twice!!
29.2 Before your first flight , have an experienced flyer
review your work. Do not fly your model until it has been
checked out by a third party who knows how to fly and how
to set up a model aircraft
29.3 Once you have completed your first flight, get in the
habit of checking your model over before and after each
flight! Don’t fly if you find something that is not right!

Thank you for purchasing a VMAR product. VMAR
Manufacturing is committed to delivering superior value
to the RC modeler. Your new EXTRA - 330L 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
others 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.
INTRODUCTION
You’ve t aken the lid of f 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 see the attached Packing List and review 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
attach the stabilizers 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!

Connect the rudder servo to the
receiver and turn on your transmitter. Confirm that the neutral positions of the rudder servo are sustained.

specifications on page 19
You can reduce the amount of throw by doing either or both
of the following:
From the servo end, move the clevis or EZ connector to a
hole in the servo arm that is closer to the servo output shaft.
From the control horn end, move the horn out further on the
threaded bolts. Always confirm that the horn is still
thoroughly engaged with the threaded bolt after you have
adjusted it.

Stage 22
Before starting the final set-up of the model, switch on the
radio and ensure that all trims are in their neutral positions.
Check that the ailerons, elevator and rudder are centred. If
any adjustments are needed, do these by uncoupling the
relevant control and turning it clockwise to shorten the
linkage or couter - clockwise to lenthen it. Only when each
control surface has been centred mechanically in this way
should you begin adjusting the surface movement
(or throw)
FINAL R/C SET-UP
Stage 23
Now confirm that the control surfaces are moving in the
correct direction. Use the servo reversing swiches on your
transmitter to reverse the direction of a servo if necessary.
The most popular transmitter mode (with the throttle on the
left, with ailerons and elevator on the right) is shown here.

Connect the clevis to the engine throttle arm at roughly half throttle. Look
into the throat of the engine carburettor as you rotate the throttle arm and
select a position where the throttle opening is about half what it is when
fully open.
