Furitek MicroPython RXF – Micro Crawler Brushless ESC with Built-in RX for MicroFlex 4WS

Introducing the Furitek MicroPython RXF – All-in-One Micro Crawler ESC with Integrated 4CH Receiver The Furitek MicroPython RXF is a revolutionary electronic speed controller designed specifically for micro RC crawlers where space and simplicity matter. This compact ESC combines the full power of the MicroPython with a built-in 4-channel receiver, eliminating the need for external components and saving critical space inside your rig. By integrating the wireless communication module and receiver directly into the ESC, the MicroPython RXF streamlines your build and simplifies wiring. It also enables seamless tuning and configuration using the Furicar mobile app, giving you quick access to all essential ESC parameters on the trail — no PC or dongles needed. Say goodbye to bulky receivers and hello to clean, efficient installs — all without sacrificing performance or control. To make it even more convenient, we’ve included all the necessary power cables compatible with SCX24, TRX-4M, and virtually all micro crawler platforms available on the market — ensuring plug-and-play compatibility no matter what rig you run. Why Choose the MicroPython RXF? If you’re building a micro crawler where space is limited but performance can’t be compromised, the Furitek MicroPython RXF is your perfect solution. This advanced micro ESC features a built-in 4-channel receiver, eliminating the need for a separate RX and freeing up valuable space in your rig. With its upward wire layout, compact footprint, and seamless integration with the Furitek MicroFlex 4WS transmitter, the MicroPython RXF brings ultimate convenience and control to your micro crawler build — without sacrificing power or tuning flexibility. Discover the freedom to build smarter with the Furitek MicroPython RXF – tiny in size, massive in capability.
