High Tech - made in Germany
Transmitter module DV4

Use your existing radio and convert it to a system with all the possibilities of the latest 2.4GHz technology. The proven more advantages and features:

2.4GHz weatronic transmission technology is easily connected to compatible radios via plug and play. The PPM signal from your radio is then converted and transferred with the unsurpassed safety and reliability of a truely redundant system. All additional settings and configurations are made with the weatronic GigaControl software which for example would give a 4 channel radio the capability to control up to 30 servos.

Easy and convenient - but the latest technology:

  • Safety ensured by 2 independent transmitting and receiving systems (true redundant system)
  • Data transmission by 2 integrated patch antennas
  • Use of all possible 80 hopping frequencies inside the 2.4GHz band
  • Highly sophisticated programming possibilities by freely programmable channels
  • Professional, simple software for all your needs
  • Easy conversion of many common radios (most are plug and play)

More advantages and features:

  • Recording of all transmitted and received data on a Micro-SD card inside the module
  • Visual and audible warnings with adjustable thresholds
  • Speechoutput of telemetry data and warnings during flight on up to 3 different customized modes
  • Telemetry sensors are using the downlink directly
  • Can be updated for free, thus always up to date
  • Optional transmission of telemetry data via Bluetooth
  • Huge Range: 3.1 miles with unobstructed view
  • Can also be used as a "listen module"
  • Apple Bluetooth authorization (only DV4 BT a)

Use the DV4 as a "Listen Module"

"Stream your flight-data for spectators!" You have also another possibility using the DV4 module, called "Listen Module" to live view all the flight data, mainly telemetry values on a large screen or on other devices. Thus, spectators are watching this data in real time - speed, altitude, reception quality, transmitter temperature, receiver voltage, the rate of climb of the model and many other values.

It requires just one additional weatronic transmitter module DV4, which receives all of the data in parallel. Then the data can be displayed with the weatronic software GigaControl. Even up to 10 different values are displayed at once. If a transmitter module with Bluetooth is used, the telemetry values can also be displayed on an Android device or even on the SkyNavi app on an iPad.

Originally the "Listen Module" was specifically designed for the GPS Triangle pilots. The position of the "Listen Module" is essential for a good reception. It should be placed according to the transmitter module specific angle of radiation and the receivers should be in line of sight. Especially in the beginning practical tests should be helpful.
