Flysky NOBLE NB4 PLUS HVGA 3.5inch LCD Touch Screen 2.4GHZ 4-Channel Transmitter Radio With FGR4B Receiver

This product uses the 2.4GHz Third Generation AFHDS 3 protocol. The Noble NB4+ transmitter and FGr4B receiver constitute a system compatible with model cars, boats, and other models. It also supports the USB simulator function (default enabled).

System Features

• AFHDS 3 Protocol: The third-generation automatic frequency hopping digital system is a newly developed digital wireless system compatible with single antenna bidirectional real-time data packet transmission and data stream transmission. With the advantages of the WS2A wireless system and the new 2.4GHz chip, the system can dynamically set the number of channels, channel resolution, range, anti-interference requirements, and latency to meet different user needs.

• Single Antenna Bidirectional Real-time Data Transmission: The receiver can receive data from the transmitter, and the transmitter can receive data from the receiver, including data from sensors such as temperature and speed, and supports i-BUS. This gives more control over the model and constant information on its current status.

• Uncorrected Data Transmission: The independent uncorrected data transmission module built into the RF system can send various types of data, including flight control data.

• Intelligent RF Configuration: Depending on hardware, certification, data transmission amount, anti-interference, latency, and distance requirements, the system intelligently adapts the corresponding RF configuration to meet user needs.

• Multi-channel Frequency Hopping: The system’s bandwidth ranges from 2.402GHz to 2.480GHz, divided into 140 channels. Each transmitter hops between 16 channels (32 for Japanese and Korean versions) to reduce interference from other transmitters.

• Unique ID Recognition System: Each transmitter and receiver have their unique ID. Once paired, they will only communicate with each other, preventing other systems from accidentally connecting or interfering.

• Low Power Consumption: The system is built using highly sensitive low-power consumption components, maintaining high receiver sensitivity while consuming as little as one-tenth the power of a standard FM system, dramatically extending battery life.

Battery Attachment

The Noble NB4+ has two batteries, one located in the handle and one in the removable base.

1. Line up the base so that the transmitter handle has a slight overhang on the back.
2. Carefully insert the base contacts into the hole in the bottom of the handle.
3. Hold the handle firmly and pull the battery backward. When secure, you should hear a click.

Beginner Mode

The beginner mode is suitable for entry-level players to improve operational safety by limiting the throttle servo.

• Setup:
  1. Go to the [Custom Main Menu] under the [MODEL] menu bar, and select the [Beginner] checkbox. After selection, this function is displayed on the menu interface.
  2. Find the function in the menu and click to enable it. When enabled, the icon will change. Assign SW controls to enable/disable the beginner function.

Function Modes

Noble NB4+ supports three function modes: Trainer, Student, and H Track.

• Trainer or H Track Mode: Accepts external signals to control the model, with the ability to recognize external PPM signal input.
• Student Mode: Only outputs PPM signals and does not recognize input signals.
• Coach Function: Two transmitters (one in Trainer mode and one in Student mode) can be connected via a double-ended Type-C cable.
• Head Tracker Function: One transmitter (H Track mode) can be connected to a headset via a head tracker cable.
