Product Description

Spektrum NX8+ 20-Channel DSMX Transmitter Only

Take complete command of your aircraft with the Spektrum NX8+ 20-Channel DSMX Transmitter. Built around Spektrum’s proven 2.4GHz DSMX frequency-agile spread-spectrum technology, this transmitter delivers 20 channels of ultra-low latency control, crisp real-time telemetry integration, and next-generation model customization. Featuring an intuitive 3.2-inch backlit color display, integrated Wi-Fi connectivity for instant firmware updates, and full Smart Technology compatibility, the NX8+ provides a modern, high-performance control interface for pilots operating scale fixed-wing aircraft, helicopters, sailplanes, and multirotors.

This advanced 20-channel radio system delivers exceptional versatility across multiple aviation and remote control fields:

• RC Hobby & FPV Aviation: Gives pilots 20 full control channels to easily manage complex scale setups, multi-stage flaps, retractions, camera gimbals, and auxiliary payload switches. Features direct AS3X+ Forward Programming support and Smart Model File loading straight from compatible receivers.

• Educational & STEM Robotics Labs: Offers university engineering programs an accessible, highly capable RC platform to study multi-channel signal routing, programmable logic switches, 24 custom mixes, and 8 sequencers across autonomous vehicle prototypes.

• sUAS Contractors & Defense Operations: Acts as a reliable, highly repeatable control backbone for surrogate testbed piloting, wireless trainer-pupil links, and field payload testing requiring programmable voice alerts and telemetry tracking.

Pro Tip: Enable Smart Model File (STF) loading on compatible Spektrum receivers. When binding, the receiver automatically transfers rate profiles, switch assignments, and telemetry configurations directly to your NX8+, bypassing manual menu entry completely.

Key Features:

• 20 Control Channels: Provides expanded control paths for complex scale features, multi-engine throttles, telemetry triggers, and safety failsafes.

• Integrated Wi-Fi & USB-C: Register your product and download firmware updates directly over Wi-Fi, or plug into USB-C to drive flight simulators like RealFlight.

• Smart Technology Integration: Displays live telemetry (battery voltage, ESC temperature, RPM) on screen without external sensors when paired with Spektrum Smart electronics.

• 3.2" Backlit Color Display: Crisp 320x240 resolution with customizable color palettes for effortless reading in direct sunlight.

• Programmable Voice Alerts: Voice alerts report flight modes, countdown timers, and critical telemetry warnings so you never have to look away from your aircraft.
