RC India

Two hours back I was flying my Cf hunter mini quad with full fpv gear from hobbysea and osd with dji naza lite (no gps fortunately, was using flysky t6 from rcmumbai,
Within 400m either it lost control or got drifted by air and flew away, I ran behind it, but it was very fast, I had my no. Written on the battery but no one called yet

My heart cries

But it's time to be practical, it could've hurt someone, am I supposed to file an fir?
Can someone cause me some trouble because of this?

It hit an old woman carrying vegetables to make a stew for her new grandson, your quad fell on her like a projectile, she is in coma now.

People are hunting you down, I'm surprised you haven't got a call till now ( perhaps with the impact the number is un-recognizable )

... hope it doesnt happen, just kidding..

and good luck.

BTW how much did it cost ?

Hope all goes well

 i almost though it was real  :giggle: and i hope that would never be the case.

open google maps and chart out the rough direction of flight and the approx range. and start
searching in that direction in a approx 15 degree arc. seek a few friends help

do it fast as time is of the essence here as the chances of someone seeing it in flight are high
and the faster you start searching the better your odds.

do not lodge an FIR yet ...


in future put your name and address on everything (there are more honest people
than dishonest ones .. )

What sort of place were you flying in? Hopefully, it is not too populated. You could try finding it from the FPV feed (if it was active) as described here: http://www.rchelicopterfun.com/fpv-crash.html (http://www.rchelicopterfun.com/fpv-crash.html)

Was flying in DU cultural fest antardhwani, in du stadium, it flew south west and kept going, it was at a crazy height, couldn't judge the direction to go as video signal was breaking, 200mw system :( no idea how the signal can break if they claim a kilometer range,
already filed a complaint to nearest PS so that following was a result of natural obstructio, couldn't find it now where, I feel like killing myself :( :'(

Did you set the Failsafe mode in the controller.

How long did you fly and the battery life left.

@asupan failsafe only works with GPS..( return to home and land..)
ribz was flying without gps.. :banghead:
 
regards

yeah, but someone told me that failsafe works without gps in naze and others, it doesn't return back, but does a safe landing on signal breakdowns..

a forum member, and my flyer friend pushpreet also lost his tricopter with the same radio,

i have figured out the flysky radios, both th9x and t6 (i was on t6) don't go upto 1km (though the seller promised me that, i'm assuming that was a marketing strategy) and you can though get a swappable module to boost range (only in th9x)

the copter just follows the last transmitted command and keeps going, though in my case i was on altitude unfortunately, so the copter maintained alltitude and kept drifting with that velocity

it goes upto 110kph and thus its pointless to locate it, was flying on a full charge 2200mah which gies it 15mins of flight, its way far and beyond reach, also i could see the point getting further but not losing the altitude

also don't fly 250's to high altitude, unless you're experienced with telemetry flights ..
the wind is capable to drift it significantly

anyone of you can provide a cheap efficient tracking system? it'll be great
how good are the gsm trackers?

I am so sad on your Loss Robin .

If you was flying with out GPS, then it is sure that the quad didn't flew away because of signal/ control loss - because under such circumstances, a Naza with out GPS will only fall down at the spot where connection is lost .

This might be due to wind - However it's not time to probe the cause for flyaway - Search as far and vast as you can - do you had a battery low voltage alarm ?

Any way you can limit your search to 1 -2 Km radius , as that is the max. range for your radio - at the moment the signal is lost, the copter will fall down - that is what happens if there was no GPS and failsafe .

If it is populated area, more chances are it is on top of a building or some thing - Might be a tree or anything, so that it doesn't get caught the attention of public, If it had a low voltage alarm , there are chances of people to find it (I found my flew away quad after hours of searching with help of low voltage alarm) .

Any way, the search can be limited to the 2 Km radius in the direction of flight (Should consider the wind at that time too !)

check this video may b this may help you...

@ribz,
Feel sorry for your loss.
Had spoken to you for the first time only 2-3 days back.
Most likely on a rooftop, so may take time to be found.

Eight years ago, my first electric airplane, an own design bipe, which i used to dismantle and carry in a Casio keyboard box on my travels, was lost in Ratlam due to high wind and getting the plane between me and the sun. I left Ratlam on completing my job there without finding it. But some of my colleagues there ran a notice on local cable TV.

A month later, a peon from our Ratlam office, turned up to meet me in Bhopal, with a bagful of bits. Only one of the four wing panels was intact, and someone stole the battery, but i got the Receiver, ESC and motor.

It may take a while, but i think you'll get it back.
Here's wishing you luck.

Its heart breaking to see posts on lost quad-rotors, i nearly lost my model today as i forgot to install Snap-Click clevis and realized it after landing (1st sortie) when low battery cutoff kicked in  :( .

Reason : had to go to field on a two wheeler so the entire model was dismantled and taken in a box .

I think you quad guys should perform range testing, set up fail safe etc and do extensive testing.

Hope you will find your lost quad.

So sorry to hear about this Robin.
I was with you there so I know how upsetting it was.

After I lost my copter the same way, I have figured that these FlySky (and other chinese ) systems are crap.
If you have to use them, keep them as close as possible.

Fortunately, I have the TH9x so I will be buying a FrSky DJT module soon, you should do the same.

As far as GSM module based GPS trackers go, I heard good things about a few.
There is also something called the loc8tor lite, look into that, and if you do plan to buy any such module, do contact me, I'll order one for me too.

Sorry for ur loss.
It's a combination of human and tech error.
Don't use flysky Rc link for anything more than park fliers LOS. In city there is wifi and what not on 2.4 so high noise floor therefore range of 1 Km is not at all guaranteed. Regardless of what others are saying, set fail safe always. The rx has to note the pulse position first to tell naza when to autoland/drop. Otherwise it will follow the last command Sent from tx.
Gsm trackers are also Rf emitters and u need to keep them far from Rc rx and GPS or it is trouble again.
Hope u find it.

Just tested the behavior of NAZA Lite with out GPS on signal loss. And I am sorry, my previous post was wrong .

The Receiver Outputs the last command from the transmitter until the Signal is regained - that means NAZA follows this signal .


PS : This is checked by switching off Tx while the quad is hovering - My quad stayed in hovering, as I haven't given any other I/P than Throttle at time switching off Tx .
I did this test in safe environment (Bedroom :rofl: ) - Don't recommend anyone to do this .

But i have encountred a similar problem while flying my plane.. was using a curred antenna receiver.. it was working fine when i switched on didnttested range and just thrown after giving 75% throttle was very fast 2200kv with 500gm model pusher..
In 50meters the receiver signal lost and suddengly it stopped all servos motor and everything and glides down...

I tested 3 - 4 times , by switching off transmitter while at 50% throttle , the quad did hold the last throttle value till signal is regained .
After that with help of friend, holding the quad in his hand, switched off Tx with a little aileron to a side - the quad continued on it's attitude to move in that direction, till the signal regained .

And Now - connected the Receiver channels to arduino and checked each channel output on serial monitor - the o/p is hold once the transmitter is switched off .

You're right Sooraj, it dint loose the altitude, and I feel like it kept following the last IP input, does that mean I have no hope finding it? With a full charge 2200 mah a racing hunter will be 30km away in 15 mins if it keeps heading the same direction

First thing is it won't fly for 15 mins on 2200mah(each motor flies at 3-4a), not going to reach 30kms away. It has to fly at 120 kmph to go 30kms in 15 mins, even a plane won't go that far.. It could max go for another 8 mins at about 5-8 kms away.
But I won't go more than few kms before hitting something. It's small form factor tricks the eye into believing it's very fast but it's not. All the best for ur search.

Ribz.sorry for the loss.i too encountered the same problem with rcb7x which is why i lost my  quad.it flew to infinity and beyond and those chinese radios are a total crap,i suggest you to buy a good radio system

few months back , i by mistake took my rcb7x for relaxed flying...... BOOM lost signal, no response. thank god the quad was coming towards me. crashed to my building. my HD camera was in the casing, so no damage!!

never trust a cheap system, just ordered a graupner!!
JK

i hope Turnigy 9xR doesnt have these issues ??

Turnigy 9xR can accept modules, so if you are going to buy that, get a FrSky module, because the Turnigy module is just a rebranding of FlySky and will have similar issues.

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.

:iagree:   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 (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- https://m.youtube.com/watch?v=Xgux5FKBBBQ
 

+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!  :salute:

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 :D
