Hi all,

I see that the original DJI FPV system transmitter isn't compatible with the new DJI 03 Air Unit. I also have a Radiomaster Zorro 4 in 1. Am I right in thinking in order to use this in place of the DJI Tx on DJI FPV kit prior to 03 e.g. caddx vista I would need to modify my old drones to include an ELRS reciever? I would also need an ELRS mini module for the remote as it's the 4 in 1 version? For new drones with DJI 03 I just need to specify a version of it with ELRS reciever added? Basically I just want one Tx for everything if possible. Thanks for the help

The answer is yest to all of your questions. Install an ELRS receiver on each of your quads and an ELRS module in your Zorro, or just swap out the internal 4-in-1 module for an internal ExpressLRS module (see HERE). Doing the latter will probably depend on whether or not you currently use your Zorro with any FrSky, Flysky, or Spektrum receiver equipped quads / whoops.

Ok thanks for all that, I didn't know you could swap internal module out.
