Glow Ignition Racing Engines

[lohring]

Some of you may be interested in a series I wrote about the development and construction of high power model engines. It's an attempt to preserve the heritage of a dying breed. I still have memories from the late 1950s of screaming control line speed engines fueled with shoe polish smelling nitrobenzene in exotic mixtures with names like Missile Mist. I hope there is enough information in these articles for an ambitious person to design and build these engines. Unfortunately, I doubt that they live in English speaking countries. Links are below:

Hi Lohring, Non of these links work for me !

Control line speed is alive and well in the US. These days it's more taking production engines and modifying them -- but the mods get pretty heavy.

I fell for that issue, everything after the last "/" is not part of the link. I've put a corrected list below.

Good reading at those linked pages, thanks for the heads up.

There's a small java app for tuned pipe design I have somewhere from way back when we used to operate on stock engines for pylon racing. See if I can find it.

Lohring,
Many thanks for that series of articles, I'm just getting interested in tether cars and some great info there.

 

[Bazzer]

Here is the link that I think Bluejets is referring to.

JavaPipe: Tuned Pipe Designer (mh-aerotools.de)

Another great source of information on tuning two stroke engines including design of the exhaust.
