Stepping a bit over the line me thinks with the Darwin Award and always bit.
Other
flying risks outrank the subject by factors.
Exhaust cabin heating can be done safely, with careful inspection and inflight
monitoring- especially with the stainless construction. In fact, my classics
cabin CO levels are determined not by the heat channels but instead by the
outlet
position of the stock exhaust (I extended it), in combination with flap
position,
speed, cabin vent/heat pressurization and the europas open fuse flap slots
in a high pressure zone.

but if you can learn the other industrial commercial level packages thats
great too; same same results... Blender has just upgraded to a full CAD
capability;
another free open source package... after a while they all taste like
chicken to me though.

ends in sudden death. Recipe for disaster and up there on the top shelf for
a Darwin Award. It needs a separation medium layer to be even remotely
considered
as an option. And with a rotax why even bother, just run it off the coolant
system.

but if someone want to through a CAD model at me i'll give it a whirl.. exhaust
is a bit more tricky due to hot gasses cooling rapidly, so speed of sound
is transitioning from x to y to z; so not that straight forward designing on
paper or computer...
