Hi Todd;
Sounds like your friend got a good deal. The 0-290 is useable for the BD
but limits the plane to a 2 place at about 150mph top speed. With an engine
that will produce 200hp or higher (possible on the rotary with good porting
and intake/exhaust design) the BD is a four place capable of 180-200 mph.
There is a very good web site for the BD-4 http://www.bd-4.org/
Bob White is installing a rotary on a flying BD. He has a web site
http://www.bob-white.com
There are several other builders that are still working on the structure of
thier BD's that are planning to use the rotary engine also.
I have purchased an engine from a '91 N/A RX-7. I stripped the engine down
to a short block and it looks as though the rotor housing closest to the
front cover is badly grooved (the oil injector line to this housing was
melted off). Also the rear (flywheel end) end housing has part broken off
(the thin portion on the plug side). Does anyone have a good rotor housing
and end housing cheap?

Hi Brian;
I wasn't aware of anyone on this list building a BD4. Coincidently, just
last week an old friend of mine who has been talking about building a
plane
since we were in high school, finally bought a BD4 project($9500cad). It's
a
BD4 that was started in 1972 by a couple of teachers, then in 1975 after
their final inspection, but before first flight they had a falling out and
the plane was dismantled & sold. It has spent much of the last 30 years in
a
barn and requires allot of work now. The engine isn't mounted any longer
and
is a Lyc O-290, which is a little underpowered for a BD4.
Naturally I immediately suggested selling the Lyc and going with rotary
power. The original mount was cut up and a modified attempt was made to
make
another (very unsuccessfully) sometime over the last few years, so he
really
is starting the FWF from scratch.
If you have a web site or know of any good ones for the BD4/Rotary, I'd
like to pass them on to him, to help sway him over to the righteous side
:-)

Jarrett,
Great work! How bout a design for the BD-4. We have several builders
including myself working on BD-4 projects that intend to use the rotary
engine.
