SPEKTRUM DX5e • RADIO USER’S GUIDE
ENDEFRIT
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“utter”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ight

information.
• Checkallcontrolsurfacespriortoeachtakeoff.
• Donotyyourmodelnearspectators,parkingareasor
any other area that could result in injury to people or
damage of property.
• Donoty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ight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.
