Rapid Racing Drone Spare ESC

These ESCs (electronic speed controllers) are the same as the ones used in the Rapid Racing Drone kit, 70-1141, so are ideal spares or replacements. They can also be used in your scratch-built projects for brushless motors up to 20A.

Armed with BL-Heli_S these Pocket Rocket 20A ESCs match all modern standards. They have an EFM8BB21 MCU, dedicated drive chips and a 3 oz gold-plated PCB. The components have been placed and soldered to an amazing standard that puts the big brands to shame. The outputs are plated solder pads rather than wires, allowing for the cleanest possible build.

These ESCs run Multishot at 48MHz, providing the very latest in performance. They are highly compact and smaller than many other common 20A units so they can be squeezed into even the tightest of drone builds. They can push a sustained 20A on a 4s lithium polymer battery.
