Just found this. Drone looking over Carlyle lake with a 'fish eye' lens.

seems odd that it looks liked it actually scares a sail boat away,
but I doubt that's the case. But the lake is way larger than the
video makes it look..

The drone may have been harassing the sailboat a bit but not
chasing. These pictures make me want to get a drone and a Hero
camera. Bet I could launch it off my Legend boat for aerial recon.

yeah, it was probably coincidence that the drone flew close to the
sailboat and the boat took off. I take it that with a drone you'd
need a really calm day though. And I noticed that the pilot of the
drone didn't get too far down the lake to be out of signal.

If he was using a modern transmitter, his range would be at least a few miles. From
the time of the flight, I'd say he was worried about his batteries dying. That is a
definite 'no-no'. The battery charge level can also be transmitted thru the TV camera
to his headset.

John, he probably came back because he didn't want to take any chances
of loosing it. Maybe he was running low on battery strength.

Those lithium polymer batteries are expensive. Running them down too low can ruin
them. I set my transmitter so I get a loud 'SQUAWK" when eight minutes of flight time
is up. That lets me know to put the plane on the ground, before it does so by itself.

Very similar to running out of fuel in a 'real' airplane!


Eight minutes of flight time? The pre-flight check done on the ground
before you even get in the cockpit takes longer than that on a "real" airplane.

Once started, it takes longer than that to taxi from the tie down area,
do a run-up and then proceed to the active runway in a "real" airplane.
Same in reverse after you land.

More "dissimilarities".

Except the old Lear jets. They shut down one engine on the taxiway so they
will still have enough fuel to fly somewhere according to my pilot buddy.
