I did bought an avionic RCB6i 2.4Ghz 6 chanel transmitter 1 and half years ago. I was able to receive it after 3 months of the order when i was too busy in exams and studies that i kept it  untried. And now after 1.5 years i am putting the batteries and switching the power on, no indicator-no lights, it ain't responding. I am shocked, though it is my fault for not checking before, i may be doing it wrong or the process is something else. The manual ain't helping,please tell me what should i do?

Check your batteries or recharge them, keeping transmitter idle does not mean they lose working

No they are good radios, i have been using it last 6 months, there are no faults, please check properly.

I have bought a fly sky T6 transmitter and a real flight simulator but while connecting with my transmitter the software is showing
"No authorised controller device found,
If u have interlink, Please plug in
If u have a realflight interface, Please plug in and make sure that radio is connected and powered up"

So, What does it mean? Why is it not connecting with the lappy?
