Help!
Dragon link glich ? Almost had a heart attack!

Ok so for the first time I flew my quad over water an kinda low over it, I had two glitches on two different flights it happens both times while flying low an close .i really have no clue why any ideas? I'm thinking it was a radio dl glich "fail safe"
Here r the glitches on video.

Look at this video minute 3:17

Look at minute 1:57

That's just multipathing. Every UHF radio I have used will do that from time to time.

Much more likely that severe vibration I see in your videos is shaking something
loose intermittently on your quad. Balance your props/motors.
Almost every time I've had a "random drop" on my quad, it's ultimately been
traced to a loose connection, be it an SMA connector, ppm or pwm connection from
RC Rx to controller, or much more often, one of the wires to/from one of the ESCs.
Sometimes I can't even find the exact problem, but I'll solve it by simply going through
every single connection, unplugging, cleaning, and replugging, and voila.. the problem
is gone. In your case, do that, but also eliminate your vibes first.
