FPV Racing Drone Builder
Racing is won in grams and milliseconds. JoinFPV's racing builder helps you trim every unnecessary screw, validate the lightest VTX/RX combo that survives a tank-wall slap, and verify your ESC can sustain the peak amperage of a 6S 2400 KV burst out of the gate. Compatibility checks block the silent killers — under-rated capacitors, mismatched DSHOT protocols, prop clearance on a 200 g sub-250 race frame.

Frequently asked questions
What's the minimum weight for a competitive 6S race quad?
Top builds land between 440 g and 480 g all-up with a 6S 950 mAh pack. Anything heavier costs you out of the gate.
Does JoinFPV calculate thrust-to-weight for race builds?
Yes. Once you pick motors, props and battery, JoinFPV computes total weight and predicted static thrust to give you a thrust-to-weight ratio — aim for 12:1 or higher for racing.
