Flysky FS-i6X Transmitter battery upgrade & Antenna mod

If you're looking for a highly functional transmitter at a low price then this is the model for you. The FlySky FS-i6X is telemetry capable, has a three position switch, three two position switches, two potentiometers, range check functionality, a 20 model memory and a huge 1km+ range.
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 transmitter 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 only accept data from the unique transmitter. This avoids picking up another transmitter's signal and dramatically increases interference immunity and safety.
This radio system uses low power electronic components and sensitive receiver chip. The RF modulation uses intermittent signal which reduces power consumption even further - no need to worry about having a thousand spare batteries.
The AFHDS2A system has the automatic identification function, which can switch between single-way communication mode and two-way communication mode on the fly. It has built-in multiple channel coding and error-correction, which improves the stability of the communication reducing the error ratio and extending the reliable transmission distance.
The FS-i6X is much smaller than many other transmitters with comparable feature sets - it won't weigh you down or take up unnecessary space in your flight bag!
