Paul,

Will this new curved design clear the mount for the KIS Crusier?
This
looks a lot more interesting to me than the previous version with
the
straight out the side exit.

Nice going Jerry.

The simple one with the side view only curved works fine Charlie.
You need to check the dimensions closely as it is a rather tight
fit
between the motor mount tubes. What does you motor mount look like.
Schertz box beam or what. Do you have a picture of the mount?

Bear in mind that blasting a stream of exhaust out perpendicular to
the
flight path is a drag hog.

For some, the vertical pipe will be the only possibility but for most
the pipe can be sloped back.  In every case, there will be less drag
than created by  hanging a muffler under the fuselage.   In my case, I
plan to tack a little piece of half round ss to the leading edge of
the
pipe where it is in the air stream, only an inch or so.    Jerry

BTW Jerry, I think it is a good idea in the future if you do a motor
mount
for somebody you do the muffler at the same time to be sure it fits.

Now you are talking!  I am still looking for a junk 13 B that I can use
for mock  up.  If I ever find one,  then I will definitely offer to
build the engine mount and exhaust system together.  Somebody out there
want an engine mount who has an extra 13B in the garage?       Jerry

Jerry, Mazdatrix has a bunch of junk housings for $30 each you might contact
them and see what they want for a set. Nothing really needs to match as all
you are going to do is bolt the housings together.
