Paul,
Is this a good size for fabricating a tangential muffler?  Is 5" diameter

tubing be large enough and .035 thick enough to handle the heat and flow
from a three-rotor?

Mark;

IMHO, 5" is small for effective tangential muffler but will work.  And .035
is will probably last since inconnel is very tough, but because it is so
thin; it will "ring" and transmit a lot of noise in the cowling.  Probably a
bit hard to weld reliably, if you want the runners to carry the weight of
the muffler.
