Hi Guys

Ian’s email address is Ian Beadle <iwbeadle@iinet.net.au>
I forwarded your question to him.
Ian uses some kind of muffler but also reduces his oulet pipe down very small as it exits the cowl, from memory perhaps 1.5”.
We plan to reduce our outlet down to 1.75” and see that does.

I sent him an e-mail, I hope he has the same  address.

I found where Ian was on this list back in  ’05.  He unsubscribed then.  I tried to send an msg to him at that  old address.  It just bounced back so if anyone can inquire of him I  would like to know what he did to muffle his  RV7.

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
