Mike,
The original PowerSport RV-3 was piloted by Alan. All
of the FWF systems were built by Everett and Steve. That airplane was a test bed
for the "Superlite" engine, which used Mazda rotors and housings but was so
modified that you couldn't recognize anything. The plane had the world record
for time to climb for prop driven small displacement aircraft for some time.
That plane was a screamer, both literally and figuratively. It had two
straight pipes dumping at the stock cowl exit. It would wake the dead. They had
to brace the cockpit floor to prevent trouble from the pulses loosening
rivets. Need I say a good muffler is in the works too? OK I am going
to check with Steve to see when we might be able to build some for the public.
As to the side plates, you can build them from aluminum, but there
is another solution that PS tried. They did a lightweight machined and
welded steel end plate only about 1-2 pounds heaver than the aluminum plate
and nitrideable just like the stocker. You would have to be running P-ports
though as there was no provision for side ports in these housings. Once I
have some quotes on the machining I'll give you some kind of price
ideas. I'm modeling the system and producing drawings for proper
produceability.

Bill,
So do you have an estimate on when these might
be available and at what price?
On a somewhat related note, anyone have any
experience with any aftermarket aluminum end/intermediate housings? I'd love
to build an all aluminum P-Port engine. The first rotary airplane I ever saw
was the original Powersport RV-3 that Alan Tolle built. That engine was all
aluminum and the airplane was so nice and light it was a rocket ship. Sign me
up!

Kelly,
Not to butt in but I am working with one of the original PowerSport guys
and we are going to work out the layouts so we can have the P-ports done CNC.
These P-ports are properly sealed, using o-rings, no goo, not welded to the
internal steel. Everett Hatch and Steve Beckham work this out years ago and
they don't leak. We plan to change just slightly from the original design
putting the butterfly outside of the port, but still at the housing face to
allow good throttle response. This needs to be available to the guys running
in aircraft. We want to make a safe and robust system.
