The DiFly ESC 50A RE features an EFM8BB21 processor with a clock frequency of 50 MHz, ensuring high accuracy in PWM signal generation and fast response to flight controller commands. Support for BLHeli_S and Bluejay allows choosing firmware for a specific flight style — from smooth freestyle to aggressive racing maneuvers, while the J-H-50 target provides additional optimization for motor operation.

Powering from 3S to 6S LiPo/LiIon makes this ESC versatile for various drone classes, and the maximum continuous current of 50 A allows the use of powerful brushless motors without the risk of overload, provided proper installation and sufficient cooling.

Package Contents: the speed controller itself and a mounting kit, allowing for quick and correct installation of the ESC into the drone frame and reliable connection to the wiring and flight electronics.

A special feature of this module is the careful selection of connectors: the main connector JST SM08B-SRSS-TB and the mating connectors JST SHR-08V-S-B for convenient and reliable wiring. This solution simplifies integration with standard flight controllers and minimizes contact wear during intensive use.

The DiFly ESC 50A RE will be an optimal choice for those upgrading their FPV drone or building a new aircraft, requiring a balance between power, response speed, and long-term stable operation in various flight modes. Suitable for racing and freestyle quadcopters, compatible with popular firmware for fine-tuning motor operation parameters.
