4PX 4-Channel 2.4GHz T-FHSS Telemetry System

Product Description

Introducing the 4PX, the most cutting-edge 4-channel radio in the Futaba fleet. The 4PX is 30% faster and 0.5 oz. (15 g) lighter than the 4PKS-R, for ultimate response and comfort. It’s fully stocked with all the features today’s drivers want — and then some.

At the heart of the 4PX is a full-color TFT (Thin Film Transistor) display that's easy to read in any light condition. This large, 3.5" (89 mm) LCD has intuitive menus and clearly labeled graphics for hassle-free operation. Racers can even monitor lap times and battery voltage in real time without having to scroll through multiple menus.


The 4PX also includes a synthesized voice for telemetry data, so drivers can hear the latest updates through the built-in speaker or headphones (sold separately). A large, assignable button on the bottom of the transmitter lets users activate key features instantly.

Compatibility with T-FHSS, S-FHSS and FASST protocols gives drivers the freedom to use the 4PX with their favorite Futaba 2.4GHz receivers. Durable, long-lasting potentiometers result in improved, precise calibration; insert a micro memory card (sold separately) to update software and transfer models from one 4PX to another.

Other highlights – like multiple crawler functions, two trigger choices and a steering wheel with drop-down option – are proven features by drivers all over the world. Of course, they only represent a small part of everything the 4PX has to offer. Click on the overview tab to get the full scoop.
