About the RF-51N Receiver


Versatile & Compact Design

The HPI RF-51N 2.4GHz 4-Channel Waterproof Receiver is a high-performance upgrade designed specifically for nitro and gas-powered RC vehicles. Engineered to work seamlessly with HPI’s TF-51 series transmitters, this receiver features Digital Frequency-Hopping Spread Spectrum (FHSS) technology for a secure, interference-free connection. Its built-in signal loss and low-voltage failsafe functions provide essential protection, automatically engaging the throttle failsafe position if the radio link is lost or battery voltage drops too low.

Compact and lightweight at just 35x26x17mm and 13 grams, it ensures effortless installation without affecting weight balance. Housed in a durable hard case with a silicone-sealed PCB, the RF-51N is fully waterproof, allowing for reliable performance in mud, rain, and snow. With four available channels, it even supports a built-in light controller for future LED accessory integration, making it a versatile and dependable choice for serious RC enthusiasts.
