Here are a couple videos of pulse jet
engines being run. The top one is a home-made pulse jet engine mounted on an R/C Long EZ. The bottom video
presents a short tutorial on how the Dyna-Jet is built, how it is made, and how to start it.

Aircraft modeling has undergone significant
changes over the decades - both in technology and preferences. Magazines like American Aircraft Modeler, and American
Modeler before that, were the best venues for capturing snapshots of the status quo of the day. Still, many things never
change, so much of the old content is relevant to today's modeler.
Whether you are here to wax nostalgic, or are
just interested in learning history, hopefully you will find what you are seeking. As time permits, I will be glad to
scan articles for you. All copyrights (if any) are hereby acknowledged.
Back in the
1950s, a company named Curtis Automotive Devices manufactured the now-converted Dyna-Jet engine (they typically
sell for >$400 on e-Bay - if you can find one). Are they still around today? Yep, only the company name is now
Curtis Dyna-Fog. One of the first pulse-jet
products aerospace engineer Russell Curtis produced was the Dyna-Jet "Red Head" miniature engine for use in
model rocketry (per their website).

According to the U.S. Bureau of Labor
Statistics' inflation calculator
the $35.00 price
in 1957 would be $269.89 in 2010 money.
Below is the e-Bay auction mentioned.
