About this build
A modern 6S 5-inch freestyle quad built around the GEPRC Vapor frame and a DJI O4 Pro air unit, taken from Oscar Liang's current step-by-step build tutorial. It suits a first-time builder who wants a proven digital parts list with wiring already worked out, and lands around 630 g ready to fly.
