Smart Throttle

The AR8020T receiver throttle port includes Smart Throttle. When equipped
with Smart Throttle the normal servo connector delivers the throttle signal to
the ESC, plus the ESC can send telemetry data like voltage and current back to
the receiver. The AR8020T receiver throttle port will automatically detect when
a Smart Throttle compatible ESC is plugged in and the throttle port will begin to
operate in Smart Throttle mode.
ESCs with Smart Throttle and IC3
battery data from compatible Spektrum Smart batteries.
If a standard ESC or servo is plugged into the throttle port on the AR8020T
receiver, the throttle port will operate normally (PWM signal) like any
conventional RC system. The AR8020T receiver is compatible with the
Spektrum Avian line of ESCs for Smart Throttle.
For Smart Throttle to function you must have a Smart Throttle ESC paired with
a Smart Throttle telemetry receiver, and a Spektrum DSMX transmitter with
telemetry. An update for your transmitter may be required for Smart features.
See www.spektrumrc.com to register and update your transmitter.
AR8020T Receiver Installation
For optimum RF link performance, mount the antennas for optimal signal
reception accounting for all possible aircraft attitudes and positions. Orient the
antennas perpendicular to each other; typically vertical and horizontal and at
different angles.
Optional SRXL2 Remote Receiver (not included): If using an optional SRXL2
remote receiver, apply double-sided foam tape and mount it perpendicular to
and at least 2 inches away from the main receiver's antenna.
Airplanes with significant carbon fiber construction can create an RF shielding
effect, reducing range. The AR8020T is designed to overcome these critical RF
issues in carbon airplanes by outfitting the aircraft with two external antennas at
specific points that will ensure secure RF coverage from all angles of the aircraft.
The AR8020T incorporates two feeder antennas; one antenna is 6.10 inches
(155 mm) and the second antenna is 7.32 inches (186 mm). They are designed
to be easily mounted through the fuselage in carbon airplanes. Each feeder
antenna includes a coaxial portion and an exposed 31mm tip antenna. The last
31mm is the active portion of the antenna.
