RaceFlight Bolt 4-in-1 BLHeli_S ESC V2

( 0 Reviews )

Built specifically to go hand in hand with the RaceFlight Revolt flight controller, the RaceFlight Bolt 4-in-1 ESC packs ungodly power into a tiny package! And now it comes with connectors, so you can quickly connect the FC and ESC without any soldering, simplifying the build even more!

The Bolt ESC is 6s capable! It also comes with external capacitors so you don’t need to get those separately. And rubber grommets are also included, preventing vibration and shock from reaching the board, increasing its durability! The board is also conformal coated, which gives the components an extra protective barrier against humidity, allowing it to perform well even in harsh conditions!

Thanks to the BLHeli_S firmware, it’s able to provide smooth performance and great flight characteristics, making it a great choice for both racing and freestyle quads that need a compact, neat, and weight efficient solution!
