I built a 75mm with the new BetaFPV board and the O4 lite. I love it. Flies great on 1s. Albert Kim posted a tip about a glue he uses to secure the cable, which I did, so it is very secure. I also picked up the BetaFPV canopy built for the O4 so mounting was not a problem. As good as the O4 pro picture is, and it's very good, the lite is the big innovation here.
Let's take flight together and elevate the world of FPV drones to new heights.
