Flysky Noble NB4+ 2.4GHz 8CH Radio TX, RC Transmitter with FGR4B RC Receiver, AFHDS 3 Protocol - Remote Controller, Surface Radio TX with Receiver for RC Cars, RC Boats (HELIDIRECT)

To attach the base: 1. Line up the base so that the transmitter handle has a slight over hang 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 backwards. When it is secure you should hear a click. - Transmitter Specifications (Noble NB4+) Product model: Noble NB4+ Adaptive Receivers: FGr4B and other AFHDS 3 receivers Adaptive Models: Car or Boat Number of Channels: 8 RF: 2.4GHz ISM Maximum Power: <20 dBm(EU) Low Voltage Alarm: ＜ 3.65V Data Output: USB Type-C Charging Jack: USB Type-C Antenna Type: External single antenna Display: 3.5-inch 320*480 full dot matrix color IPS touch screen Resolution: 4096 Distance: >300m (Ground distance without interference) Online Update: Yes Temperature Range: -10° C~+60° C Humidity Range: 20%~95% Color: Black Dimensions :131.41*115.95*190.56mm Weight :520g Certification: CE，SRRC，FCC ID：2A2UNNB4PLUS00，MIC，RCM - Receiver Specifications (FGr4B): Product Model :FGr4B PWM Channels :4 RF :2.4GHz ISM 2.4GHz Protocol: AFHDS 3 Antenna Type: Single Antenna Input Power :3.5~9V/DC Data Output :PWM/PPM/i-BUS2/S.BUS/i-BUS Temperature range: -10℃ ~ +60℃ Humidity Range :20% ~ 95% Online Update: Yes Dimensions: 17*29*16.6mm Weight: 6.4g Certifications: CE, FCC ID: N4ZFGR4B000

• This product uses the 2.4GHz Third Generation AFHDS 3 protocol. The Noble NB4+ transmitter and FGr4B receiver constatute a system, compatible with model cars, boats and other models. and it also supports the USB simulator function (Default enabled).
• AFHDS 3 (third-generation automatic frequency hopping digital system) is a newly developed digital wireless system. It is compatible with single antenna bidirectional real-time data packet transmission and data stream transmission. With the advantages that come with the WS2A wireless system and the new 2.4GHz chip, the system can dynamically set: number of channels, channel resolution, range, anti-interference requirements and latency to meet the needs of different users.
• Single Antenna Bidirectional Real-time Data Transmission: The receiver can receive data from the transmitter and the transmitter can receive data from the receiver, this includes data from sensors, such as temperature and speed and support the i-BUS. This gives more control over the aircraft and constant information on its current status.
• Uncorrected Data Transmission: The independent uncorrected data transmission module is built into RF system; it can send many different types of data including flight control data.
• Intelligent RF configuration: Depending on hardware, certification, the amount of data to be transmitted, anti-interference, latency and distance requirements, the system intelligently adapts the corresponding RF configuration to meet the requirements of the user.
