[NSRCA-discussion] OS exhaust

[Ron and Nancy Lawrence]

Hi Guy's,  Our Vivat's are also mounted in the center of the pipe.  We just 
clamp a little aluminum mount on a lord mount and fish it in from the front. 
Sounds hard but it's not that bad.  In 2 years with mine I have never broke 
a header or pipe.   Ron Lawrence

Not if you have a dremel tool.  <VBG>
I mount mine much the same as noted below.
And yea, my Vivat has a 2 by 3 inch double Immelmann shaped hole
to access the O ring and lord mount.
Bottom of plane is black, hole is not noticeable in flight.

  But with designs like the Brio and Vivat, aren't you limited to the inlet 
and/or stinger?  Access to the mid-pipe area is a problem on this type of 
airplane.

    The only thing I could add to Nat's statement is that in my exhaust 
set-up the pipe is also soft mounted on a single Lord mount. Same location 
as Nat. Been doing that for at least the last 10 years and have never had a 
failure in any exhaust component in a 2 stroke powerplant. Really don't 
remember the last time a coupler blew either, but then again I don't fly as 
much as many do.

Anthony
With soft mounted engines I have never had a header failure with a single
pipe support placed about 1/2 to 1 inch behind the CG of the pipe/coupler.
