Randy,
Have you ever seen the twin-engine Cozy the brothers in Argentina built
using two Suzuki car engines? The engines are installed in a
Siamese configuration. I read that they actually had an engine
failure over open water while on one trip back from Oshkosh, reportedly
caused by an ignition failure. They were able to continue flying
and safely landed with only one engine. As I recall, it used twin
counter-rotating props driven by cog-belts. They could shut off
either engine and run on the other engine for economy. It may be
possible to do the same thing using two 13B engines. For weight
reasons you would likely need to use the Racing Beat aluminum end
housings.

My rejection of the Defiant is
based on
1. The lack of builder support. This is a perception on my
part as I
have "only heard" that RAF no longer supports one-off plans
builders.
2. Too expensive to operate when compared to the Mk-IV. (including
fuel
and insurance)
3. It doesn't fit my mission profile. By that I mean that I
will
occasionally fly long distances over water and will therefore
occasionally need the supposed "ultimate" reliability.
The rest of the
time, that extra engine is just extra weight making airplane
noises.
4. I just don't like it, and I don't want to build one. Not
gonna make
me, either! :-) How's that for being
"defiant?"
But still I think you are missing my point. I never set out to find
the
"ultimate reliability" in the first place. I only wanted
to see if I
could improve the reliability of the airplane that I was going to
build.
The answer to that question still may be no. And that's ok.
That will
lead to some level setting of my expectations as a result. And I
do
appreciate the locater service that Jesse provided and I'm sure it
will
be a good fit for someone.
