Hello, I recently build a 210 quad. First 2 flights was really good, but when i was flying it 3rd time it just falls from the sky. It was really strong snowfall so maybe it is the cause of this? My Betaflight log here
No worries what you wrote is clear and the black box log is pretty hilarious . Was imaging it as watching you take off a little wobbly at first then start flying forward for a bit and then all of a sudden it tumbles sorry to laugh at it but was a bit comical to watch and play out in my head/on screen.
Anyhow to me it looks like the back left motor either got disconnected or otherwise blocked (wasn't producing thrust but was trying to go full throttle on that motor to recover from the tumbling most likely).
Make sure your battery wire is totally clear of the props and held up in place well with a zip tie I've had that or antenna get into the props many times (usually on landing or crash but it's happened in flight before as well)
If you can't identify any physical damage would bench test with the props off each motor individually to be sure the connection between motor/ESC is working reliably and signal is getting from FC to ESC, from black box logs it appears the receiver input was consistent.
