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.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction
and with the recommended throws).
Check all the control horns, servo horns and clevises to
make sure they are secure and in good condition. Replace
any items that would be considered questionable. Failure
of any of these components in flight would mean the loss
of your aircraft.
Test run the engine and make sure it transitions smoothly
from idle to full throttle and back. Also ensure the engine
is tuned according to the manufacturer’s instructions,
and it will run consistently and constantly at full throttle
when adjusted.
Recommended Center of Gravity (CG)
An important part of preparing the aircraft for flight is
properly balancing the model.
Caution: Do not inadvertently
skip this step!
The recommended Center of Gravity (CG) location for
the Pulse
™
XT is 2
3
/
4
" (70mm) behind the leading edge
of the wing against the fuselage. Make sure the aircraft
is inverted when measuring the CG. If necessary, move
the battery pack or add weight to either the nose or the
tail until the correct balance is achieved. Stick-on
weights are available at your local hobby store and
work well for this purpose.
Note: The range for the center of gravity
is 2
1
/
2
" (63mm) to 3" (76mm).
Pre-Flight
Range Test Your Radio
Range check your radio system before each flying
session. This is accomplished by turning on your
transmitter with the antenna collapsed. Turn on the
radio in your airplane. With your airplane on the ground,
you should be able to walk 30 paces 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.
