•
Ensure that your batteries have been properly
charged prior to your initial flight.
•
Keep track of the time the system is turned on so
you will know how long you can safely operate
your system.
•
Perform a ground range check prior to the initial
flight of the day. See the “Daily Flight Checks
Section” for information.
•
Check all control surfaces prior to each takeoff.
•
Do not fly your model near spectators, parking
areas or any other area that could result in injury
to people or damage of property.
•
Do not fly during adverse weather conditions.
Poor visibility can cause disorientation and loss of
control of your aircraft. Strong winds can cause
similar problems.
•
Do not point the transmitter antenna directly
toward the model. The radiation pattern from the
tip of the antenna is inherently low.
•
Do not take chances. If at any time during flight
you observe any erratic or abnormal operation,
land immediately and do not resume flight until
the cause of the problem has been ascertained
and corrected. Safety can never be taken lightly.
Safety Do’s and Don’ts for Pilots
Step 1
Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 4.3V on the
transmitter or below 4.7V on the receiver. To do so can
crash your aircraft.
Note
: When you check these batteries,
ensure that you have the polarities correct
on your expanded scale voltmeter.
Step 2
Check all hardware (linkages, screws, nuts, and bolts)
prior to each day’s flight. Be sure that binding does not
occur and that all parts are properly secured.
Step 3
Ensure that all surfaces are moving in the proper manner.
Step 4
Perform a ground range check before each day’s flying
session.
Step 5
Prior to starting your aircraft, turn off your transmitter, then
turn it back on. Do this each time you start your aircraft.
If any critical switches are on without your knowledge, the
transmitter alarm will warn you at this time.
Step 6
Check that all trim levers are in the proper location.
Step 7
All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch harness
moves freely in both directions.
