Hi Paul,

    I did my first taxi test last Friday.  I taxied for about 30
    minutes and it didn't even get close to overheating.  Of course, the
    Texas summer isn't here yet, so we'll have to wait and see how it does
    then.  Everything worked as intended and it was great to experience my
    little creation moving under its own power.  First flight is still

a
    month or so off.

    Thanks,
    Mark S

    Congratulations Mark. Your 3 rotor engine installation looks great.     Got any later pictures?

 Here are three very recent ones taken just last weekend (3/4/07).

Thanks,

You do beautiful work Mark.

Great work!  I see you are not (apparently) using an air filter.  Is
there a current consensus on the value of using an air filter?  This
would add considerable complexity to my project, and would be nice to
do without.

Scott,
Look a little closer, its there.  There is a butterfly valve which
diverts the air through the filter element until I get up to a thousand
feet or so and then I can switch it to ram air.  This was one of the
more difficult items I had to build.  It didn't have to be, but I made
it more complicated than necessary.  It uses a flat, rectangular HO
Mustang filter element.  I have some other pictures I took during the
fabrication process.  Either way it is "ram air", but one is filtered
and the other isn't.
