Yeah, it sucks been there.
P2V+ $1,400 never flown a bird, just a couple of RC cars.
It was defective day one intermittent video signal, I didn't want to send it in, flew it anyways 10% of the time, video signal worked for 30 secs then it wouldn't come back..
Made me a careless flyer, always had a sd recording, it always came back (RTH).
My attitude was, it is already broke.
Finally sent it in, got it back, now it works.

Then I would loose video and telemetry at the same time. Bring it back maybe it would hook up, or maybe required a full restart.
Was up in the woods, lost signal I could still see it, this was normal to me, kept flying my plan, started getting harder to see, then it disappeared.
I had relied on RTH so much, I didn't think I could loose it.
So this is the short version.
I and friends spent much fuel and time looking for it. ALOT.
I'm here now because I have no friends.
Anyways I still look for it every year.
Today I think a bird took it out.
I have a memory problem, I remember way to much and I irritate my (no) friends.
Thanks for the video loss refresher.
Keep the questions coming in.
Before I forget look at some of
