Regardless of the brand and its cost and quality, all rc links are prone to failure. The best we can do  is to set failsafe, rth with gps or fly in safe distance in los. Either way, flysky is good enough as other radios but there could be other issues that no other radios couldnt have handled too. Wait, we havent confirmed its the radio link failure.

   Even I won't say a Naza or any such Autopilot systems can be foolproof - same the case for any radio .

just out of curiosity how is your fail-safe set ? b/w tx-rx or tx-rx-ap ?

We can't set up failsafe if using NAZA M lite with out GPS .And Flysky FS-T6 don't have it's own failsafe .

Mine is frsky djt module on tdy9x. Failsafe is set with ele up , ail left and throttle zero, so when there is signal lost, it should glide left and probably can come within the range to regain control. A failsafe and timer is minimum you can ask for a radio.

A picture of the so much loved late hunter drone 

pravesh736 15+ trips to nearly 2-3 kms area with considerably tall buildings and no sign of it..

a little research and i found normal copters (450) have been taken to 126kph
http://www.rcindia.org/self-designed-diy-and-college-projects/using-cellphone-as-fpv-system
see sunlikestar's post and proof photo,
and with a full front stick, a 250 racer goes upto 150kph

also the copter gives 10mins on a 1500mah, with 2200 its gonna be more (theoretically, haven't tested max flight time)

for the third thing, copters with no failsafe keep moving with last ip with altitude enabled,
and no building is 500-900m high

these points are enough to predict its in some another state right? such a fun thing

i couldn't see the orientation of the copter at that height (the dot was that) and it was far, i gave the max stick, it went even far, too late to realise this and reverse the stick direction i realised that its just going the same way, switched my tx off, but it kept going, followed it till i was stopped at several checkpoints and the dot disappeared

30 kms southwest from here is haryana, possible?

I am in Haryana now. It takes a lot for a human to get here from delhi. Quad impossible.
Btw u need to go more than 2-3 kms, I stated 5-8kms. u say it flies far, why searching only 2-3 kms. That don't make sense.
Btw that 126kmph is a plane. Gotta read.
250 quads are slower than proper 450 but it's easier, cheaper to fly 250. I Fly a 250 too. Saying it does 150kmph is bulldung. The racer name doesn't make it faster, nor does calling it a drone make it failsafe on its own.
It's known copters with no failsafe move in last input given, I was the one to mention it here first. 500m- Why were u so high up? Dont get offended(I know it's hard at this age), it's partially ur fault(flying untested, beyond ones capability and understanding, no failsafe) for loosing it, as much as it hurts, I am trying to put sense so that u don't loose another. Also once it flies away u never know what it could hit or do. Half kg brick it is.
I know how fast quads go-

+1 to pretty much everything Pravesh wrote. Love this video and would like to know, were you flying with a different camera than the video.

@pravesh736,
Great video and fantastic flying! 

Hope Robin gets his model back...

nice video pravesh, don't know about the camera in video ashimda, but i had a mobius and a sony 420 tvl in it, well now i aint doing fpv with uhf modules
