You learned a valuable lesson on how radio signals work. If the goggles are close enough to the drone (and there are no other radio signals around the goggles) then the drone can be behind obstables because the radio signals can bounce around them. When the radio signals hit objects, some get absorbed and some get bounced. Reinforced concrete and metal bounces well and only absorbs a bit. Leaves bounce very badly and most of the signals are absorbed. We leaves bounce nothing and all of the signals are absorbed. So if you are close enough, there is still some signal left that can bounce and reach the goggles. But when you are at distance then there is not enough power left, because of how quickly the power dies over distance. This is the inverse square law. If you double the distance, you cut the signal strength not by 50% but by 75%!!!! Therefore on occusync 4, even if you are flying in perfect conditions, no water in the air, no radio singles around the goggles, and in FCC mode as soon as you are 300 to 400 meters away from the goggles, the drone can NOT go behind hills and mountains. Buildings, maybe. A single tree, perhaps. But tons of dirt? It can not bounce around it. Keep this in mind next time you are flying, always know your distance. 400 meters out, tell yourself if I dip behind this I will crash! So you always need to know where you are. DJI makes this easy with the H indicator. Turn around once in a while to figure out if you are still on direct line of sight. To summarize: past 400 meters you need to always have direct line of sight or you will lose all signal. Finally the control signal is different because it gets picked up by the drones, while video gets send by the drone. So when video starts dying you still have some time to send out a control signal. Pressing break would have leveled out the drone and flip in to normal mode. After that you would probably also still have altitude readings on your display. After a little wait you could have then given more trottle and see altitude go up, and then you would have signal again. When I doubt go straight up, it will make the signal go direct line of sight again!
We turned the drone over and added power. You should practice in the simulator first. But why didn't you press the emergency stop button? A very stupid accident.
Hi, I did press the emergency stop button but too late. As in my description I defaulted to gain height by putting the left stick fully up, which you would do when flying an Air 3 or Mini drone. Simply my fault.
You did not turn around on time to see if the H symbol was still lining up (meaning you have directly line of sight) and you where not aware of your own position vs the drone otherwise you have turned to the other side. It was the turn to the wrong side that made you insta lose vid signal. Beyond 400 meters in FCC mode, dropping behind anything hill is game over. You can survive dipping behind a building cause that bounces nicely, and a single tree the signal can go around it. But hills are full of sand and water and that absorbs 100% of the RF before it reaches your goggles.
Noppe, only if you also lose control signal. You can lose video (signal send out by the drone) and still have control signal (signal picked up by the drone)
Isn’t it odd how people love to take a swipe and kick someone for making a mistake? You have to hope you don’t have people like those who comment here around you in real life as you will never be good enough for them - whatever you do
You really need to keep a close look on the video mbit. anything 30 to 60 mbit is fine keep flying. When you go under 15 mbit start paying attention. Under 10 mbit? Alarm bells should start going of, it's probably time to fly back to a higher mbit rate. Under 5 mbit, you are in danger. 1 mbit? GO STRAIGHT UP NOW! The only exception to this is if you are doing a long range flight. When I fly 5 km away from myself the last 500 meters or so in some condition might be 1 mbit the entire time. But for long range the control signal is more important then the vid signal cause you can fly on readings.
@@camperanddroneguy When Avata loses its signal and dives into the ground, it is really worrying. I've seen a few videos where, after Avata lost its signal, it returned safely home without any problems. Your two crashes makes me very nervous every time signal on my Avata is weak and in the red.
@@Iron_Pan Return to home does work, it's saved me many times when I've pushed it too far. Just the crash's you've seen have happened a couple of seconds before RTH can trigger. My fault, the Avata works as it should.
I'm sorry for your crash hope it's ok. But can you tell me how to get the map on the screen like yours? It looks like google maps, or is some other third party app? Thanks
Should have gone to failsafe rth instantly. My dji fpv does that if i loose signal suddenly. Its scafy cos goggles go dark. But even if your diving straihjt at the ground and loose signal it should instantly stop (emergency brake doeant matter if your upside it just stops and hovers to your preset altitude and comes back. Any idea why that sidnt happen? Considering its the latest
Because he still had control signal, dji does not instantly do this on loss of video signal, only on completely loss of control signal. And even then it's not instant, it takes a couple of seconds.
On the avata 2 this only happens when you lose control signal. If you lose vid signal and still have control it does not happen. It also takes 2 seconds or so. If the last thing you do is give 100% throttle but you are not level, then you are at the ground before those 2 seconds have passed.
@@camperanddroneguy Yeah. Happy landings then 😉 I took the DJI care as well for the Avata 2. FPV flying is definitely way more exciting and it just screams 'hit that gap man' 😎
