George,
While I hate the noise and ultimately will
need to do something about it, after 15 years of building I'm ready to fly for a
while. I'll leave the experimentation to somebody else.
I was willing to give the DNA a try because
it was relatively inexpensive and being off the shelf, relatively easy. It was
also ineffective. Now if you or somebody else builds your design and proves it
works I'd be willing to give it a try, but I dont want to invest my time to
fabricate another failure.
I'd give Al's tangential a try if I could
figure out how to make it fit.

Bill,
I have net Ian Beadle in Perth, I think his
airstrip is slightly NW of Perth, but didn't get out to the airstrip to see
the plane.
With all the experimentation on exhausts I'm
wondering why people don't try the exhaust that Bill Jepson and myself
designed - I have put it up here a number of times.
Does it appear too difficult !?

If you want to have a quiet rotary powered
plane, you need to get someone in Australia to talk with Ian Beadle
to see what he has done with his RV6 powered with a
Renesis.
This plane is quiet! I don’t know where
Bindoon is located….

You just need to fly at Mach 1 so you stay ahead of
the sound. ;-)
Can anyone report on the effectiveness of the
tangential muffler in actual real world situations? (As I recall Al G.
is running a tangential muffler on his Velocity.) I ask because I'm in
the process of building one for my Lancair with the hopes that it will work
better than the DNA muffler that I'm currently running. I think it
will work better at reducing the noise level in the cabin, but at what cost
to power? Hopefully, this will save me the cost of a new Zulu ANR
headset. Comments appreciated.

Hey
gang!
I came across a
rare find this weekend.
Any serious
rotorhead will certainly appreciate this.
Bluelines from
1973 of the General Motors Wankel Rotary
engine.
I just put them
up on eBay
