As I have mentioned several times in the past, more and more readers have been asking for sources for parts or identification of an old-time engine they have obtained. Such is our first letter this month. I imagine that this can be attributed to the swing to electric power rather than internal-combustion
engines, which seem to be dying a slow death judging by the number of
engine manufacturers that have closed their doors. Our first letter is
typical of ones that we have received lately.

From Dennymites to Four-Strokes and More!
Email your questions to Clarence Lee at MAN@airage.com. q&A
UI have a small collection of
older spark-ignition engines
that include an O&R 60 and 23,
Super Cyclone, and McCoy 60.
However, I rec ently visited a
yard sale and bought a beat-up
control-line airplane with a
motor that says “Dennymite”
on the plate on the side of the
engine, opposite the exhaust. I
have never heard of this engine
and wonder if you can tell me
anything about it.

Answer: Yes I can, Ken. The
Dennymite was a very popular
free-flight engine back prior to
WW II due to its light weight and
power output. A lot of fellows
also used it in tether car racing.
A famous British Hollywood
actor named Reginald Denny had
been a modeler in his younger
years and opened a hobby shop
Radioplane Company employee Norma Jean Baker later became known as Marilyn Monroe.
The 1938 Dennymite Airst ream (later called the “Tin Can model” by engine collectors)
was a popular free-flight and tether race-car engine prior to W W II. The first ad for it
appeared in the July 1938 issue of MAN.
