2. Flysky FS-i6 6CH 2.4G AFHDS 2A LCD Transmitter Radio System for RC Heli Glider Quadcopter DIY Drone
 

The Flysky FS-i6 is a affordable, 6CH 2.4G radio system and also a very simple setup for your RC vehicle. The automatic frequency hopping digital system provides a strong, reliable 2.4GHz signal, so rest assured you'll always be in control. Included in the package is a 6-channel mini receiver that will fit in most vehicles. The ergonomic feel of the trasnsmitter will feel good in your hands even after long track sessions.

Features:
Reliable, interference free 2.4GHz AFHDS 2A signal operation.
6CH operation.
Use only 4 * AA batteries for transmitter.
Quick and extremely stable in performance.
Simple binding procedure.

Highlights:
Works in the frequency range of 2.405 to 2.475GHz.This band has been divided into 142 independent channels,each radio system uses 16 different channels and 160 different types of hopping algorithm.Silm design on transmitter for easy handling!

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.

AFHDS2A system has the automatic identification function,which can switch automatically current mode between single-way communication mode and two-way communication mode according to the customer needs.

AFHDS2A has built-in multiple channel coding and error-correction,which improve the stability of the communication,reduce the error ratio and extend the reliable transmission distance.
