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.
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.
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).
