For some reason, in
more than half a century building and flying model airplanes, I have never owned
or operated a diesel engine. I have nothing against them, and in fact would like
to procure and run one, even if just on a test stand, before assuming dirt
temperature. Diesels have a couple advantages and disadvantages compared to glow
fuel engines, according to my recollection from reading about them over the
years. Compared to glow fuel engines, diesels produce less power for a given
volume displacement. The absence of a glow plug can make them more difficult to
start, especially when hand-flipping and/or in cold weather. To their credit,
diesels are not quite as noisy as a glow fuel engine, the diesel fuel will not
attack painted surfaces as readily, and if you need a larger diameter propeller
for your scale model, the extra low-end torque facilitates their use. Oh, and
with a diesel, you'll never have to replace a burnt-out glow plug. That's from
memory, which at 67 years old, may be a tad faulty. This advertisement for the
Deezel 1/7th horsepower diesel engine appeared in a 1955 issue of Model
Airplane News magazine. The $1.95 price in 1955 is the equivalent of
$22.95 in 2024 - quite a deal then and now!
