Caddx Vista

Setup MSP for DJI FPV Vista / Air Unit

Take away:

  • When MSP is working, you get the quad voltage instead of N/A and the low power mode message when you plugin, then as soon as you arm the quad the unlocked message and frame rate message appear
  • Temperature protection set to Off will make the unit output its full power as soon as you plug in the quad (requested to get the video out via USB)
  • Vista and Air Unit have protections against over heating, they will not allow themselves to be damaged because they over heat

Joshua Bardwell made a good video about DJI FPV short range because of MSP misconfiguration.

How to tell if a Vista or Air Unit is damaged

  • Take a multimeter
  • Check the continuity between Ground and TX, then RX : there should be none
  • Check the resistance between Ground and TX, then RX : it should be mega ohms worth
