system as it fails. Large or small, our
models are all subject to crashes because
of mechanical or human failure. We try
to prevent accidents as much as possible
and make the best split-second choices
In the case of this often-discussed
crash, I think endless speculating is
pointless. Seeing the video made me think and consider what I
might do in a similar situation, and that is the only useful part
of this whole affair.
Andrew Kestin sent me a story with a sad ending. He is an
experienced RC pilot who lost more than one model to the
same faulty ESC. It was salvaged from a crash and reused after
being carefully checked.
The component tested fine on the ground, but Andrew said
the problem arose during aerobatic flight while the ESC was
exposed to vibration, heat, and power loading. By the time he
realized the cause, another airplane had bitten the dust.
We are living in the luxurious age of
reliable electronics, and ESC failures
are rare. I would have been fooled, too.
Andrew now does thorough preflight
checks and is skeptical of component
bench tests that are conducted when the
part is cool and not under load.
Real Trippy, Dude
On the subject of electronics, I
recently was at an informal fly-in held at
a public park. It was fun, but I noticed
the electrical charging setup shown
in the photo on the previous page. It
doesn’t look optimal, does it?
I guess that plugging multiple units
into one outlet is okay considering the
low current draw and the beefy splitter,
but how about the knee-high cords?
I could imagine someone—possibly a
