Avata LOST due to latency and overconfidence, waterfall dive in!

- I ain't gonna use any editing or colorgrading or stabilization for this video, I want you to see what I saw, the adrenaline rush I got on each clip, if you see too much shakyness, it is because my hands were shaking :)
I'm starting this FPV learning path, and I did not consider latency at all here, the avata is a great drone, but it has its limitations, I know this now, and I want to share my insights.
I have a good knowledge of electronics, and a good knowledge of software, so I made a LOT of mistakes here.
My first mistake was underestimating latency:
Avata has around 60ms latency if you set it to see the full HD image in your goggles 2, there is a base rule (that now I know) that if you fly at 50mph at 5ms latency, you are far 11 cm from what you are seeeing in your googles, that means I may have 12 times that distance at 50mph, I was flying at around 30mph (60% of 50mph), so I may be around 6.6cm distance from reality for what it is in the drone, 12 times because I had 60ms of latency, so I had a distance course correction of 80cms off aprox.
My second mistake was underestimating bottlenecks in data:
Goggles receive data from the avata's main camera, they are quite nice, detailed, and not like those low res FPV that I've seen (now I want that low res haha) if you go from a latency, your main transmitter (avata) will try to stream that into your goggles, producing a queue of data, that will over time will get sincronized and will reduce your latency.
I was coming out of no connection, so there was a stream of data to be synced with the goggles, probably not much, but It may have hurt the real data I was receiving
My third mistake was trying to capture amazing acro shots with a cinewhoop (which I should have driven more carefully)
My fourth mistake was facing down while flying:
This decreases signal and increases the possibility of a bottleneck, hence increasing the chances of creating a bottleneck, fly, facing your FPV, ALWAYS
My fifth mistake was getting too confident on the simulator, ok, I have 72 hours in the simulator, I can do pretty sick moves, look on how much you achieved, the simulator DOES NOT SIMULATE LATENCY I REPEAT DOES NOT SIMULATE LATENCY, nor wind conditions.
What is my take on this?
- This path is expensive.
- Do not underestimate latency.
- Low res is lower latency (I should have guessed that)
- Find the best equipment for what it is supposed to do
- ALWAYS wear an sd card in your goggles to use as a blackbox on a crash (all the footage from this video is from that)
- Wear a battery strap on your avata, otherwise you won't know what happened to it.
Still this was my first dive on a waterfall, so I'm pretty happy with the shots I had (even though I lost the main source of it)
Avata is very good, is very noisy, but it has the momentum stabilization issue due to wind conditions (which is ok if you fly high) but the battery falling off is a real problem.
I hope what I learned yesterday helps you tomorrow, enjoy the video!
