Hello Paul,
How are you going these days. Could you add me back on the news
letter. I am back into the Mustang now as I have almost finished the
Lightning. I hope to fly it in the next 4 weeks.
I think you also know I have purchased a Berkut that I will put a
rotary in. I have two Renesis engines but i hope the 1.6 litre will be
out by the end of the year as I would like to use one in the Berkut.
It would be good to get any info on this new engine and anything else
that has been happening with the Renesis engine.
I would like to find
a ignition unit that has Auto advance in it and can handle the Mazda
coils with some redundancy. I had a fire in flight last year and lost
my plane and was lucky to get it down and get out. [Not a Mazda powered
airplane.] I will not use high pressure fuel injection in a plane. It
was lucky in one way that the fire was through an oil spray. If I had
had any high pressure fuel lines it would have been over. I was running
a Revmaster carb with gravity feed and there was no fuel fire.
I would use them again as they are safe and the performance was well
up.
I hope to hear from you soon Don

Sorry to hear about the in flight fire. Was that a Jabiru engine?
We are working on a custom dual carb set up for the Teflon
slide throttle p-port engines. It will be cockpit lean-able unlike
a Weber and have 1-7/8" ID throats. People will actually be able to buy
it off the shelf. No need to build your own.
No sign of the 16X. It may never appear. I am after Mazda to put
the 3 rotor in the RX8 and call it the Daytona Special as they won
the 24 hour GT class last January 2008. Mazda were outnumbered ten to
one by $100,000 Porsche's and five laps ahead at the end. Mazda could
easily charge $50,000 for the 3 rotor RX8 Daytona Special.
Details of the race on youtube.
Lots of things have happened since you were gone Don.
We are now swimming in rotary aircraft engines. Rotamax showed up at
Sun & Fun with half a dozen. Some installed in aircraft. One or two have flown.
Somebody adapted the German AIXRO rotary kart engine to power an ultralight.
In case you have not heard about it that is the engine somebody pumped
up to 100 HP and flew over Mount Everest in a powered parachute.
It is about the size of a soccer ball. Foot ball for those in
the rest of the world.
We now have 27 videos, mostly on the subject of rotary AC engines, on youtube.
To view them put in "RX7 Airplane" in the youtube search engine.
The one with the greatest hit rate is our p-port mod to the RX8 engine
with a SS tube tig welded to the steel rotor linear. We got about 264 HP
out of that set up at 7500 RPM on the Mazdatrix dyno. Real easy to build but
it may also be available off the shelf. A yet another new cast bell housings is
also in the works for the Mazda. Idles real well as the side exhaust ports
are still there.
I expect Mark Suspinski to fly his p-port Teflon slide throttle Mustang
any day now. Starts right up and idles fine at 2000 RPM. He got it running last
summer. I think we got 240 HP at 7500 RPM on the Mazdatrix dyno as I recall.
Mazdatrix also built that engine. I had a lot of water leak trouble with the
bonded in p-port port tubes and I had to do it over. That is when I invented
the tig welded SS p-port tubes. Worked far better than I expected.
Robin and I have been thinking of coming out to Perth again.
Maybe some time next winter. I would like to explore the west coast
of Australia.
