Check Your Radio
Before going to the field, be sure that your batteries
are fully charged per the instructions included with
your radio. Charge both the transmitter and receiver
pack for your airplane. Use the recommended charger
supplied with your particular radio system, following
the instructions provided with the radio. In most cases,
the radio should be charged the night before going
out flying.
Before each flying session, be sure to range check your
radio. See your radio manual for the recommended
range and instructions for your radio system. Each
radio manufacturer specifies different procedures for
their radio systems. Next, start the motor. With the
model securely anchored, check the range again.
The range test should not be significantly affected. If
it is, don’t attempt to fly! Have your radio equipment
checked out by the manufacturer.
Note: Keep loose items that can get entangled
in the propeller away from the prop. These
include loose clothing, or other objects such as
pencils and screwdrivers. Especially keep your
hands away from the propeller.
Double-check that all controls (aileron, elevator, rudder
and throttle) move in the correct direction.
Check the radio installation and make sure all the
control surfaces are moving correctly (i.e. the correct
direction and with the recommended throws). Test run
the motor and make sure it transitions smoothly from
off to full throttle and back. Also ensure the engine is
installed according to the manufacturer’s instructions,
and it will operate consistently.
Check all the control horns, servo horns, and clevises
to make sure they are secure and in good condition.
Repair or replace any items that would be considered
questionable. Failure of any of these components in
flight would mean the loss of your aircraft.
Range Test Your Radio
 1. Before each flying session, be sure to range
check your radio. This is accomplished by turning
on your transmitter with the antenna collapsed.
Turn on the receiver in your airplane. With
your airplane on the ground and the engine
running, you should be able to walk 30 paces
(approximately 100 feet) away from your airplane
and still have complete control of all functions.
If not, don’t attempt to fly! Have your radio
equipment checked out by the manufacturer.
 2. Double-check that all controls (aileron, elevator,
rudder and throttle) move in the correct direction.
 3. Be sure that your transmitter batteries are
fully charged, per the instructions included with
your radio.
Flying Your 4-Site
Flying the 4-Site is about as fun as it can get. Very light
wing loading and extreme control throws make for some
precise F3P flying. Verify that your CG is at the correct
location as per the manual and that you have your rates
set up to your liking.
Verify all control throws are in the correct direction and
the motor spins in the correct direction as well. Point the
model into the wind and add some throttle trim until the
motor begins to turn. This will be your flight idle. We
recommend hand launching the model if you are flying
from of a rough surface.
Apply power slowly. You will find the model will
become airborne very quickly and at a low speed. This
model excels at flying slow and easy. Trim the model
for level flight at half throttle. Only use full throttle for
maneuvering.
You will find you can adjust the CG to your liking by
moving the battery pack fore or aft on the fuselage.
To land the 4-Site just reduce the throttle to idle and feed
in up elevator until the model settles into a slightly nose-
high attitude.
Gently fly the model down to the landing spot with a
final flair at touchdown.
We hope you enjoy the 4-Site as much as we do.
Happy landings.
