To pick up on the 2 cylinder engine discussion, for those that might
be interested, I have been test flying a direct drive, v-twin Generac
industrial engine (generators, weed cutters, etc), with 38 peak hp, on
my Thunder Gull. There are others flying with re-drive versions, as
well as some Briggs, Kohler and Honda efforts too. All this is
discussed onhttp://groups.yahoo.com/group/Small4-strokeEngines/.

I did a series of reports on my development and testing there. Search
thru the old messages on "Generac" for my reports. Sorry, I don't want
to repeat any of that here, so I am back to lurk mode.

I am in the middle of a Generac fiasco now. A homeowner I built a
house for installed a Generac generator and it has an intake fire
every time it tries to start... Not a good thing for sure. I have a
video and am going to post it on YouTube soon. If I am not wrong the
Generac unit uses a Vanguard engine, basically a top of the line
Briggs & Stratton motor... They seem kinda heavy for aircraft use
though... JMHO...
