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
