Now I am new to this 'game' but I think the Flysky i6 and Turnigy version are the same. Now I have seen that the i6 can have custom firmware loaded that unlocks all 10 channels. It also has mixing and two way comms for sensors,rpm volts etc. This thread is talking about mixing on planes but I would imagine the principal is the same. I bought one just 'cause it was mega cheap at £32 for TX and RX
