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….

Kelly,

 

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
