i had similar crash and it was due to being agressive on the throttle, the esc amps which are written on the esc box or at the esc manufacturer website is the maximum amperage for the whole esc when pulling power from the battery, and so when i go to full throttle and i had amp display in my osd( calibrated !!) i had seen something around 100Amps when the esc is designed to 55A so, i think your crash may be due to being agressive on the throttle (100%) and it simply just gave up. I am maybe wrong but it could be the case, and even if it is not i suggest putting calibrated amperage in osd.
Hi my friend, first of all I hope that you get your big bird back and that it didn’t crash on a rock 🙏🙏. I think, the reason for this failure is overheating, maybe an esc. You pulled full throttle for around 20 seconds and gained a lot of altitude. In this flight position, the cooling airflow inside the quad is very low because it’s blocked by the battery. You get much more airflow through the quad when you fly straight forward. And at the end you see a massive drop in the voltage, from one second to the next. For me, this indicates a short circuit or a burnt cell of the battery pack …
@ yeah, these are the daily lessons for all fpv-pilots. Some of these lessons are extremely hard but very useful on the other side … thanks so much for sharing and I‘m keeping my fingers crossed that your big bird is back again soon 🥰✊
@@mog59 Yeah, you're absolutely right. I hope this will be useful to someone. Thanks, brother, and I'm also hoping we'll find the bird - we're heading out in a few days...
727mAh in 34s is 77A average current. I'm guessing this is a Samsung 40T 6S2P pack. 40Ts hate delivering 30A+ for any extended period, and I imagine you killed a cell if not a spot weld, or solder joint somewhere.
secont: 41 sec full throttle at end means esc or motor can be burned (damaged). failsafe and rth are not configured correctly.
first that i see, wrong position on quadricycle. radio is bloked.
More than 20 seconds 100% throttle……..

Lesson learned! Appreciate it, man - good luck up there!

Man, if I’d known that sooner… :)) It’s well-known that we keep learning as long as we live... Thanks, brother, good luck up there!

3rd: li ion can't deliver 700mah in 41 sec
LiPo
@@Wild__FPV ok. but i think it's low C cause voltage drops. battery overheated. first what i see here its voltage drop and quad disarm.
@@AlexJaniashvili Here are the specs for the battery I used when I was flying: iflight-rc.eu/en-hr/products/fullsend-e-6s-8000mah-battery

Fullsend LiPo 8000 mah... Thanks man!
isnt failsafe?? u hold trotle 100%?? omg.
It’ll be better next time! :)
