DUPLEX REX3 Assist SHV A20cm

Art. No.:
JDEX-RR3A-SHV-A20

Description

The system is continuously improved. Thanks to online updates the improvements are easily accessible to users from any part of the world. From the very beginning bidirectional transmission has been a distinctive feature of the Duplex system, this not only handles telemetry data, but it also helps to ensure secure primarily transmission safety between the transmitter and receiver.
 

The Duplex EX telemetry system uses an open protocol. This gives the advantage of compatibility with a large number of telemetry sensors from both JETI model and third party producers. For the display of telemetry data you can use purposely designed equipment like the JETIBOX profi and DC/DS transmitters or you can display the data on PCs.

The 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.


3-channel receiver compatible with JETI EX and EX Bus protocols, with Assist. Supports telemetry functions. Features a PPM input, PPM output, an integrated expander for devices supporting EX and EX Bus protocols, and a UDI digital output.

The receiver belongs to the SHV (Super High Voltage) category. It is designed for onboard system voltages of 3.5–28 V.

This receiver has a 20 cm antenna with a counterpoise.
