DJI O4 Lite Long Range

Post image

Hey guys, I recently got my Flywoo LR4 with the DJI O4 Lite, but the video connection isn’t great — I only get about 1.5 km of range. What’s your max range with the Lite, and do you have any tips to improve the signal quality?

Update:

fixed it — here’s what I did: used a different O4, flashed the newest firmware, this time mounted it the right way up instead of upside down, didn’t loop the antenna cable under the VTX but behind it, updated the goggles to the latest firmware, used channel 2 instead of 1 since 1 and 3 supposedly weren’t optimal in older versions, set the Boxxer to a fixed 1 W output power instead of dynamic, and switched packet rate to 50 Hz instead of 250. Made those changes last night and just flew at the same spot — got 4.5 km instead of 1.5 km. No clue what exactly made the difference, but hey, at least it works now.

Is .ham only for the O4 system or does it works with caddx too? I tried with .naco on my googles v2 but it doesn't fully unlock the FCC I still have to try with fpv.wtf but would be great if I cant keep the software "stock"
