Bouncing around what to do about monitoring my single rotor, on the
ground and in flight, I looked at a zillion of possibilities. Non met my
requirements of being simple and affordable and still doing the job. I
even went so far as building a timer for my small camera taking a
picture every few seconds. I never finished it.
Now I discovered GoPro, and suddenly my problems were solved.
The first picture is what the camera is taking, and the second is zoomed
in to whatever I want to look at.
The camera is clipped to my front harness taking pictures at the rate I
set it to.
I think every first flight should have it so the pilot does not have to
worry about not reading engine data, and can safely fly the airplane.
