computer radio control systemThe REX A receivers enhance the REX series of receivers and extend it with the intelligent flight stabilization feature, which is designed 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 Tx modules and DC/DS transmitters.You can set them directly via DC/DS transmitters, alternatively you can use the USBa adapter and JETI Studio software (free download at www.jetimodel.com). The receivers provide internal telemetry (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.In order to stabilize the airplane model effectively in flight, it is appropriate to equip the model with high speed digital servos. Stabilization is also suitable for combustion engine models.REX Receivers with Assist Functions1 IntroductionENGLISHFW. ver. 1.054ENJETI model s.r.o.Lomená 1530, 742 58 PříborCzech Republic - EUwww.jetimodel.comwww.jetimodel.de[email protected]Duplex-System EX:• Transmitter modules • Receivers • Telemetric sensors • Compatible accessories • Display units Serial number:Carefully save this serial number!www.modellmarkt24.ch

computer radio control system2.1 Properties Up to 16 stabilized airplane channels. Support for different multicopter types – from tricopters to octocopters. Up to 3 adjustable flight modes, options for stabilizing the horizon and altitude. In-flight gain tuning using free channels. Using the latest 3-axis gyroscope and 3-axis accelerometer. Support for LED strip consisting of WS2812 chips. Support for external camera gimbal driven by servos. Intelligent fail-safe. Vibration analysis. Full set-up options with DC/DS transmitters or via PC. Available telemetry: Receiver voltage, signal quality, G-force, attitude orientation. Support of telemetry and up to 3 sensors connected directly.2.2 Important Notices 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. Always check the polarity of the lead wires so that the voltages on the receiver and other electronics are not reversed. Do not expose the receiver to heat and sudden temperature changes that may affect the accuracy of the sensors. 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. When installing on a combustion engine model, keep in mind 6ENJETI model s.r.o.Lomená 1530, 742 58 PříborCzech Republic - EUwww.jetimodel.comwww.jetimodel.de[email protected]Duplex-System EX:• Transmitter modules • Receivers • Telemetric sensors • Compatible accessories • Display units Serial number:Carefully save this serial number!www.modellmarkt24.ch

computer radio control systemthat all electronics must be optically isolated from the ignition unit and ideally located as far as physically possible from the engine itself. 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). 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. Always use a sufficiently sized power source for the receiver and servos. Keep in mind that with the stabilization switched on, the servos in the airplane model are constantly moving, resulting in increased current consumption and subsequent heating of the components. Any major changes to the settings (especially for the initial configuration) should be done without the propellers fitted. 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. REX A receivers do not support Clone mode. This is because the stabilizing receiver should always be the primary receiver in the model. Other receivers, serving as satellites, must not have the stabilization enabled.7ENJETI model s.r.o.Lomená 1530, 742 58 PříborCzech Republic - EUwww.jetimodel.comwww.jetimodel.de[email protected]Duplex-System EX:• Transmitter modules • Receivers • Telemetric sensors • Compatible accessories • Display units Serial number:Carefully save this serial number!www.modellmarkt24.ch

computer radio control system3.1 Installation in the modelAlways place the receiver in the model parallel to the flight axes and ideally as close as possible to the center of gravity (especially for multicopters). This is important for the proper functioning of stabilization 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 the right place. We recommend using a double-sided adhesive tape for this purpose.3 Installation8ENJETI model s.r.o.Lomená 1530, 742 58 PříborCzech Republic - EUwww.jetimodel.comwww.jetimodel.de[email protected]Duplex-System EX:• Transmitter modules • Receivers • Telemetric sensors • Compatible accessories • Display units Serial number:Carefully save this serial number!www.modellmarkt24.ch
