Ma-RX42-S 5CH Receiver - Compatible With FUTABA-SFHSS With Built-in ESC And MicroRX Function

About This Product

RC hobbyists, this Ma-RX42-S receiver is a serious upgrade for your Futaba-compatible setups! The 5-channel design gives you plenty of control options, and the built-in 5A/1S brushed ESC is super convenient - no need for separate speed controllers in smaller builds. The micro size is impressive at just 18.5x12.0x6.5mm (without antenna) and ultra-lightweight at only 0.9g including antenna, making it perfect for micro and mini RC vehicles where every gram matters. The working voltage range of 3.0-5.0V covers most small-scale applications perfectly. What's really smart is the automatic binding feature - after powering on, it automatically enters pairing mode and waits for your transmitter signal, so no more struggling to reach tiny binding buttons after installation. The start-lock function is another great safety feature that prevents the brushed motor from accidentally starting up, only releasing the lock 2 seconds after your throttle stick hits the lowest position for the first time. This is the basic edition without telemetry function, but it still supports connecting to external brush or brushless ESCs if you need more power. The updated design from the 2016 version is noticeably more stable and reliable in operation. Perfect for micro drones, small RC cars, and other compact projects where space is limited but you still want full Futaba SFHSS protocol compatibility. The construction feels solid and the performance has been rock-solid in my testing. Whether you're building a new micro RC project or upgrading an existing one, this receiver delivers professional-grade performance in a tiny package that won't weigh down your build. Seriously impressive engineering for such a compact and affordable receiver!
