Spektrum NX8+ 20 Channel DSMX Transmitter Only - Advanced RC Control

Our review of the Spektrum NX8+ finds it best suited to experienced RC pilots and hobbyists who need advanced mixing, telemetry and Smart technology support in a single transmitter. The NX8+ stands out for its combination of 20-channel capability and out-of-the-box Smart compatibility, making it a compelling choice for pilots flying complex models such as EDF jets and giant-scale balsa airplanes. For those after a robust programming interface, the backlit 3.2in, 320x240 resolution screen and Wi-Fi firmware convenience are strong reasons to consider the NX8+.

Key Features

• 20 channels: Provides the channel count required to manage complex mixes and multiple control surfaces on large or multi-function models.
• AS3X+ Forward Programming: Enables advanced stability and handling tuning so models track better in turbulence and during maneuvers.
• Smart technology compatibility: Works with Smart batteries and Smart Avian ESCs so pilots can view essential telemetry during flight.
• Backlit 3.2in display: A 320x240 resolution screen with multiple palettes and user-customizable colors makes navigation and programming easier in varied lighting.
• Wi-Fi connectivity: Simplifies product registration and firmware updates without needing a wired connection to a computer.

Who It's For

The NX8+ suits intermediate to advanced RC pilots who fly EDFs, giant-scale models, or aircraft needing extensive mixing and telemetry feedback. Those who already use or plan to use Smart batteries and Smart Avian ESCs will get the most value from the transmitter's telemetry integration and convenience.

Less experienced flyers seeking a basic beginner radio, or pilots who need a simple two- to six-channel controller, should look elsewhere for a lower-cost, simpler transmitter. The NX8+ is feature-rich and best appreciated by users ready to program and fine-tune their models.
