Free Online FPV Drone Builder
JoinFPV is a free online FPV drone builder. Pick a frame, flight controller, ESC, motors, VTX, camera, LiPo battery and propellers, and the builder checks electrical and physical compatibility as you go. See the build in 3D, estimate thrust-to-weight and flight time, preview the Betaflight CLI configuration, and ask for an AI review of the finished build.
Open the builder — the builder needs JavaScript and WebGL.
