A: All 2.4GHz signals, not just DSM, are affected by
proximity to conductive materials such as carbon
fiber or metal. Few RTF and ARF sport airplanes or
helicopters use enough of these kinds of materials for it
to be an issue. If, however, you’re flying a sophisticated
model that uses a lot of conductive materials in
its construction, a Flight Log can be helpful. The
information it collects when you fly will help you
determine the optimum location for your receiver(s) so
you can minimize the effects of these materials on your
signal performance. For more details on the Flight Log
and how it works, visit SpektrumRC.com.
GENERAL INFORMATION
Servo Precautions
• Do not lubricate servo gears or motors.
• Do not overload retract servos during retracted or
extended conditions. Make sure they are able to
travel their full deflection. Overloading or stalling a
servo can cause excessive current drain.
• Make sure all servos move freely through their
rotations and no linkages hang up or bind. A binding
control linkage can cause a servo to draw excessive
current. A stalled servo can drain a battery pack in a
matter of minutes.
• Correct any control surface “buzz” or “flutter” as soon
as it is noticed in flight, as this condition can destroy
the feedback potentiometer in the servo. It may be
extremely dangerous to ignore such “buzz” or “flutter.”
• Use the supplied rubber grommets and brass servo
eyelets when mounting your servos. Do not over-
tighten the servo mounting screws, as this negates the
dampening effect of the rubber grommets.
• Ensure the servo horn is securely fastened to the servo.
Use only the servo arm screws provided; the size is
different from other manufacturers.
• Discontinue to use servo arms when they become
“yellowed” or discolored. Such servo arms may be
brittle and can snap at any time, possibly causing the
aircraft to crash.
• Check all related mounting screws and linkages
frequently. Aircraft often vibrate, causing linkages and
screws to loosen.
General Notes
Radio controlled models are a great source of pleasure.
Unfortunately, they can also pose a potential hazard if not
operated and maintained properly.
It is imperative to install your radio control system correctly.
Additionally, your level of piloting competency must be
high enough to ensure that you are able to control your
aircraft under all conditions. If you are a newcomer to radio
controlled flying, please seek help from an experienced pilot
or your local hobby store.
Safety Do’s and Don’ts for Pilots
• 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.
