AR500 FAILSAFE

• Prevents unintentional electric motor response on
start-up.
• Eliminates the possibility of over-driving servos on
start-up.
• Establishes low-throttle failsafe if the RF signal is lost.
• The AR500 removes servo output pulses to all channels
except the throttle channel during failsafe.
• The AR500 throttle failsafe position is stored via the
throttle stick position on the transmitter.

HOW AR500 FAILSAFE WORKS

RECEIVER POWER ONLY
• In electric aircraft, when the receiver only is turned on
(no transmitter signal is present), the throttle channel
has no output, to avoid operating or arming the
electronic speed control.
• In glow-powered models, the throttle servo receives no
input so it remains in its current position.
Note: Some analog servos will coast slightly even
though there is no signal present. This is normal.
• All other channels will move to the positions set
during binding.
AFTER CONNECTION
• When the transmitter is turned on, and after the receiver
connects to the transmitter, normal control of all
channels occurs.
• After the system makes a connection, if loss of signal
occurs, the AR500 failsafe drives the throttle servo only
to its preset failsafe position (low throttle) that was set
during binding.
• All other channels receive no output pulses/ commands,
and are not active during failsafe.

SERVO REVERSING

The DX5e features servo reversing on channels 1–4. The
switches are located at the lower front of the transmitter
and are used to select the direction of each channel. Use
a small screwdriver to change the switch position to
normal or reverse.

HI/LO RATE

The DX5e offers a high/low rate function on aileron,
elevator and rudder. When the HI/LO rate switch is in the
upper position or "HI" position, 100% travel is achieved
on the aileron, elevator and rudder channels. When the
switch is in the lower position a reduced travel of 70% is
achieved on the aileron, elevator and rudder channels. This
is useful allowing the aircraft to have a high control rate
(switch in the "HI" position) for aggressive maneuvers and
a low control rate (switch in "LO" position) for smooth,
precise maneuvers.
• High 100% rate on aileron, elevator and rudder
• Low 70% rate on aileron, elevator and rudder
