how about FlySky FS-i6 review...?

If you are looking at good radio in budget then you can for it. Its really a very nice radio and got good range for FPV quad racing and planes.
If you plan to increase your budget then there are plenty of radios available with telemetry and many more features.

Thank you very much sir for details information..

Still.....How much range(in meters) ? If you can give some idea !!

Approx radio range 500 to 700 meter.

Thank You
But as per your experience, is it enough while flying your stuff in the air
I mean do you feel like going little further.

Did u ever face crashes because of the responsiveness or bad/low connectivity of this transmitter.
And what about failsafe.....(Hope i am not asking too much  )

Yes enough rang for far flying , without fear.
But depending present your environment. Like havey electric line.

No, not any crash related radio range, and fail safe is good for save your stuff crash 

Thank You so much
