NEWS: Eachine DTX3, switchable power 5.8G VTx with builtin DVR

It’s not an AIO FPV camera but a switchable power 5.8G VTX including a builtin DVR and up to 72CH: You select either 25mW, 50mW or 200mW. Works fine from 1s up to +5V but you will need a BEC/Vreg from 2S systems. Definitively, I hope the DVR part will be superior to their former 4-in-1 module where when recording was turned on, the FPV connexion became so laggy…. Impossible to fly FPV in such conditions. It seems to be since I can recognize the three button of a HMDVR module. 7g standalone… so you will have to add two extra gram for the FPV cam. Clearly more adapted from 120mm brushless machine.

  • Mui Chee How says:

    Low band?
    Legal to use those frequency?

  • Ben says:

    There is the usual 2 wires (black and red interlaced) to give the power to the camera/transmitter. Still badly named on the manuel and Banggood photo (red wire is called “ground”, as on the TX03 description/manual, but of course red wire is “positive” and not ground).

    What are the other 3 wires (red/black/yellow) => I guess it is audio/ ground/video, but is it an input or a local output ???
    It’s no described anywher …
