E-Sky has created a newly designed 2.4GHz frequency band,"2.4GHz" RC system with advanced Spread Spectrum Technology and digital FSK(frequency shift key)Coding Technology. This offers many advantages compared to traditional 72 MHz transmitters.

Traditional remote control distance for helis and park flyers is about 250 meters,requiring a transmitter with 750mW transmitting power consumption. But 2.4GHz transmitter just needs 14mW power to perform at the same level.

2.4GHz uses binding or FSK,to prevent signal interference when flying in large groups.

2.4GHz remote control systems employ an integrated frequency synthesis and FSK(frequency shift key) technology,which automatically programs and sets the working frequency via the microprocessor. Flyers can enjoy a glitch free flight without changing crystals.

The signal between the transmitter and receiver use a redundant data stream to ensure accuracy.

The Radio system offers quick response and reduced servo chatter.

2.4Ghz RC System frequency wave range is 1/4 of the usual used frequency wave range. The transmitter antenna is just 14.5cm in length and the receiver antenna is greatly reduced over 72MHz. Normal binding operation is simple:
1. Power on the transmitter, the indicator on 2.4G transmitter will blink for 3 seconds. This indicates that transmitter is sending code binding information.
2. After 3 seconds, the blinking 2.4G transmitter indicator becomes solid.
3. Connect the receiver or 4in 1 mix controller, observe the receiver or 4 in 1 mix controller. 2.4G transmitter indicator blinks two times and turns solid, which indicates that the reception of the channel data is successful and you are ready to fly.
Transmitter manual For use with E-Sky 6 channel 2.4GHz receiver (EK2-0424) Note- 8 "AA" batteries not included. The manual indicates that the transmitter comes with a charger. This version does not come with a charger. Note: The E-Sky 2.4GHz system is not compatible with any other brand of 2.4GHz radio system. If we find out of a brand that it compatible, we will update this note. It appears that the different manufacturers have their own proprietary software. Important Notice: To use this transmitter in airplane mode, there are dip switches under the battery compartment that may need to be changed. Please refer to the picture (click for larger format) to see the switch locations. This information was missing from the manual.
