The RaceFlight Bolt 4in1 electronic speed controller (ESC) was designed for power and performance. Coupled with the Revolt FC the Bolt makes a thin stack while keeping the escs save inside the frame, protected from prop strikes. The escs are also safe from vibrations thanks to the integrated RaceFlight Gummies.
The RaceFlight 4in1 is also extremely easy to install. It is compatible with 4s through 6s batteries and has a built-in current sensor that hooks up directly to the Revolt to provide amp draw and mAh consumed information. The Bolt can pin into the revolt and provides the Revolt power.
