Description

The RadioMaster TX16S Mark II V4.0 ELRS is an FPV/RC radio controller built for pilots who value precise stick feel, a dependable RF link and comfort during long sessions. The Mark II version features updated internal electronics and optimised power delivery, so the radio remains stable under load, while charging is simpler and safer. Via USB‑C it supports up to 2.2A, and the improved charging circuit includes reverse-polarity protection — handy when you often swap batteries in the field.

Special attention has been paid to control feel. The V4.0 Hall gimbals deliver noticeably better centring and a more predictable throw, reducing “zero drift” as temperatures change. The S1/S2 knobs have more distinct centre detents, while the LS/RS sliders move more smoothly with a clear centre position. Additional rear grip pads help tailor the hold to your palm, and the revised shell offers neat, tight fitment with no play.

The built-in 2.4 GHz ELRS module (SX1280) provides fast response and adjustable output power up to 250 mW — a practical balance between range and energy efficiency. The radio supports up to 16 channels, runs EdgeTX (pre-installed) and OpenTX, includes a JR-compatible external module bay and a standard 3.5 mm TRS trainer port. For private listening to voice prompts and telemetry there’s a dedicated 3.5 mm audio jack, and the rear DIY port is useful for custom solutions and mods.

The TX16S Mark II is a versatile choice for anyone who wants to build a “main” radio once and then fly and control models confidently — without compromising on precision.
