The REX A receivers enhance the REX series of receivers and extend
for airplane models and multicopters. This stabilization works in all
three axes of the model and facilitates flying in windy or otherwise
challenging conditions. Aerobatic maneuvers will be more
accurate and smoother. With the help of several flight modes,
which are also suitable for beginner pilots, flying practice will be
really easy.
The REX A receivers are compatible with all existing 2.4GHz Duplex
You can set them directly via DC/DS transmitters, alternatively you
can use the USBa adapter and JETI Studio software (free download

it with the intelligent flight stabilization feature, which is designed
(e.g., receiver quality, inertial unit status and G-force level). They
also process telemetry from external sensors compatible with
Duplex EX or EX Bus

ź Up to 16 stabilised airplane channels.
ź Support for different multicopter types – from tricopters to
octocopters.
ź Up to 3 adjustable flight modes, options for stabilising the
horizon and altitude.
2.1. Properties
ź Available telemetry: Receiver voltage, signal quality, G-force,
attitude orientation.
ź Full set-up options with DC/DS transmitters or via PC.
ź Support of telemetry and up to 3 sensors connected directly.
ź Vibration analysis.
ź Always check the polarity of the lead wires so that the voltages on
the receiver and other electronics are not reversed.
ź Do not expose the receiver to heat and sudden temperature
changes that may affect the accuracy of the sensors.
ź Support for LED strip consisting of WS2812 chips.
ź Intelligent fail-safe.
ź Using the latest 3-axis gyroscope and 3-axis accelerometer.
ź Support for external camera gimbal driven by servos.
ź In-flight gain tuning using free channels.
2.2 Important Notices
ź Always use the current firmware in your DC/DS transmitter and
receiver. The minimum version of software for transmitters
supporting REX A receivers is 4.24.
ź When installing on a combustion engine model, keep in mind
ź Never use a receiver that is visibly damaged. In particular, check
the state of the antennas regularly. In no way modify or remove
the receiver electronics from the supplied housing.

ź Any major changes to the settings (especially for the initial
configuration) should be done without the propellers fitted.
ź During use, it is recommended to switch on the transmitter first
and then the receiver. The transmitter confirms that the receiver is
turned on by an acoustic signal. When turning off the system, first
switch off the receiver and then the transmitter.
ź Always use a sufficiently sized power source for the receiver and
servos. Keep in mind that with the stabilisation switched on, the
servos in the airplane model are constantly moving, resulting in
increased current consumption and subsequent heating of the
components.
ź Do not expose the receiver to excessive vibration. Sensors in the
receiver are very sensitive and vibrations are an undesirable
phenomenon. It is advisable to check the vibration level with the
built-in analyzer before flight and to take appropriate measures
to reduce vibration (e.g. attach the receiver in the model with a
soft double-sided adhesive tape).
that all electronics must be optically isolated from the ignition
unit and ideally located as far as physically possible from the
engine itself.
ź Do not expose the receiver to direct air flow. Aerodynamic forces
may have a strong influence on the sensitive barometric sensor
when the model is moving faster.
ź REX A receivers do not support Clone mode. This is because the
stabilizing receiver should always be the primary receiver in the
model. Other „A” type receivers, serving as satellites, must not
have the stabilisation enabled.

3.1. Installation in the model
ideally as close as possible to the center of gravity (especially for
multicopters). This is important for the proper functioning of
stabilisation and its correct response. It is important that the
mounting of the receiver is made in such a way that the vibrations
from the model are minimized and that the fixation is guaranteed at
Always place the receiver in the model parallel to the flight axes and
the right place. We recommend using a double-sided adhesive tape
