| I paid fifty-five dollars for my OS40LA,
A pity -- it's not a very good engine. Oh, it works, but it's lacking
in power and I've heard they're finicky. A Thunder Tiger 36 or 46 at
$75 or $79 would be a lot better. But more money, so ...

As suggested, it's very much a niche market. Davis wants to make some
money, but doesn't sell too many, so he charges a lot.
| Who else makes diesel conversion heads?
As far as I know, nobody. There's little demand for diesel R/C
engines (though our stock engines work on the same principle, except
that the glow plug helps the fuel ignite) so there aren't many sold.
Why? I know some people don't like the smell of the fuel. Beyond
that, I don't know, but it's true -- they're rare. I've heard that
the diesel conversion heads are very finicky to make work, but that
the engines that were designed as diesel from the beginning are not.
From what I can tell, you've got a very limited budget. So I'd
suggest not messing with diesel for a long time, if ever. You
mentioned you wanted to do it to keep the noise down -- well, if you
want something really quiet, you go electric or unpowered glider. But
you can quiet a glow engine too by using a prop on the larger end of
what's suggested, and sometimes you can improve on the muffler.
