Watch out guys. If you close the throttle at high RPM you
could collapse the flex hoses. Move the butterflies down
stream near the rotor housing if you can.

I don't think I will be flying with those SCAT tubes, that is for
development.  The tubes will have to be contorted into such a strange
path it is impossible to predict on a CAD drawing.  So I will use those
until it's all mounted in the plane, then make fiberglasss replacements.
I use a 3" SCAT tube now between the airflow sensor and the throttle
body and have had no problems in 400 hours.  That is some pretty stiff
wire coil inside that tubing as you will find out if you have to cut it
or bend it.

If it is SCAT with an inner liner the inner liner has been known
to separate and block the air flow.

Don't say "impossible" That is like waving a red flag in front of a
bull :)

The "SCAT" with the inner liner is called something else, can't remember
now what it is called, I've never used it.

As talented as you are with Rhino, I'm not sure you could model all the
strange bends those four tubes are going to make.  I twist the whole
assembly around and the tubes just go where they can/will.

Rhino has this function called "Pipe". It will build a pipe
around any arbitrary curve in 3D space.

You could fill that SCAT stuff with plaster after
you got them in the right position so they would hold
the shape for making a mold. Wrap some duct tape around it
to smooth it a bit.

Maybe you could use that  as a male buck to make
a female mold for the runners. Or... just use it as a male
mold and use a slitting saw to get the parts off. Then
glue to the two half's back together with another couple
of wrap layers.
