1. Introduzione
The Flysky Noble NB4+ 2.4GHz 8CH radio transmitter offers advanced flexibility and functionality for remote control applications. This updated model features enhancements in appearance, structure, hardware, and software compared to the previous Noble NB4. It is designed for precise control of RC cars and boats.
The NB4+ supports the entire series of FlySky i-BUS2 devices, as well as compatible devices from Hobbywing (XeRun Axe R2 Esc) and Power HD (GTS-3, GTS-5, GTS-6, GTS-7). Remote parameter adjustment is supported directly from the transmitter, allowing for multiple parameter adjustments to suit various usage demands. The 2CH (Ultra-fast) Mode provides ultra-low latency for critical control responses.
