Spedix LS40 Slim 40A BLHeli-32 ESC (3-6S w/F4 Core & RGB LED)


This new LS40 Single ESC from Spedix features the latest STM32L431 F4 Core Processor which is 50% faster than the STM32F051 and accepts a Continuous 40A Current with 50A burst, and includes a programmable RGB LED! The best part is that it’s only 9mm wide x 38mm long (6mm thick) so it fits perfectly on the latest quadcopter frame arms such as the new TBS Stardust SB5 Pro/Race without any overhang!!! External ESC’s have been long known to be more reliable, less expensive, and easier to replace than their 4-in-1 counterparts!

These Slim F4 Core ESC’s also feature a heavy duty heat-sink to protect it from common broken/bent prop strikes plus there’s a built-in programmable RGB LED for increased visibility without the hassle of extra exposed wires. They are powered by a full-size 40V MOSFET making them tough and extremely durable!

Weighing in at only 7.5grams each, these Slim next generation F4 Core (STM32L431) powered 3-6S BLHeli-32 ESC’s are the bees knees! Grab a set of 4 for your newest Race or Freestyle build (or replace older ESC’s on an existing build) to increase reliability and performance and get ahead of the curve with the all new Spedix LS40Slim Single ESC’s!
