Homemade quad 250. Feofania park, Kyiv, Ukraine.
Unfortunately, last couple of seconds of footage was not recorded. The quad was in water about 5 min. All props got broken. There were no more mechanical damages. I disconneted battery, and after couple of hours blowed the quad with hot air.
Switching on showed not working camera and video transmitter. Have managed to fix them replacing some electronic parts. So the quad is healthy now and have already done several flights.
Frame-by-frame viewing at 0:02:38:000 showed smth that possibly is a part of broken propeller. See 3 frames at the end on the right.
