FlySky FSi6 2.4G 6CH AFHDS RC Radio Transmitter With FSiA6B Receiver for RC FPV Drone Engineering Vehicle Boat Robot Precise details: Overview: The Flysky FSi6 Transmitter is a goto transmitter for RC plane and drone enthusiasts around the world because of its configurability and robust operation. It has an impressive list of features, it comes at a competitive price, and it's popular with combat robotics builders. It is an excellent radio for robotics. Six channels lets you control all sorts of addons: lifters, and more. The Flysky FSi6 Transmitter is a digital proportional radio control system that operates on the global ISM band of 2.4GHz frequency, making it suitable for usage across the globe. The use of standard 2.4 GHz and AFHDS protocol make it compatible with most combat robotics systems. There is both a knob and switch for both Channels 5 and 6. This allows you to set a motor speed or servo position, then switch it on to that preset position. No crystals to buy, and no need to worry about other radios interfering with your robot. The LCD display and programming buttons allow the user to set up the transmitter without requiring a laptop and a connection to the transmitter. The FLysky FSi6 has a dramatic number of options and capabilities, all configurable through the LCD display. FSi6 Transmitter Specifications: Channels: 6 Channels Model Type: Heli/Airplane RF Range: 2.402.48GHz Bandwidth: 500KHz Band: 142 RF Power: Less Than 20dBm 2.4ghz System: AFHDS 2A and AFHDS Code Type: GFSK Sensitivity: 1024 Low Voltage Warning: less than 4.2V DSC Port: PS2;Output:PPM Charger Port: No ANT length: 26mm*2(dual antenna) Transmitter Weight: 392g Package Weight: 676g Transmitter Size: 174x89x190mm Package Size: 23.5x21.2x10.6cm FSiA6B Specifications: Features: This radio system uses a high gain and high quality multi directional antenna,it covers the whole frequency band. Associated with a high sensitivity receiver,this radio system guarantees a jamming free long range radio transmission Each transmitter has a unique ID,when binding with a receiver,the receiver saves that unique ID and can accepts only data from the unique transmitter.this avoids picking another transmitter signal and dramatically increase interference immunity and safety. This radio system uses low power electronic components and sensitive receiver chip.The RF modulation uses intermittent signal thus reducing even more power consumption. AFHDS 2A system has the automatic identification function,which can switch automatically current mode between singleway communication mode and twoway communication mode according to the customer needs. AFHDS2A has builtin multiple channel coding and errorcorrection,which improve the stability of the communication,reduce the error ratio and extend the reliable transmission distance. Package Included: 1 x Flysky FSi6 transmitter (color box) 1 x Flysky FSiA6B Receiver
