With all the muffler ideas out there like the tuned tangential
muffler,
the simple tangential muffler, the VAM and the turbo charger I have
slowly come to the conclusions that this is the only way to build a
motor
mount. You need as much clearance around the exhaust side of the
engine
as you can get and this is the best way of doing it. I call it the
beam
mount. The beam and the upper diagonal brace must lie in the same
plain. It must also be laterally braced under the oil pan.

Paul,  for the Tailwind and RV types,  can the tube  that runs from
the
front bushing to upper end of the gear receiver be eliminated?  The
lateral bracing under the engine should should be sufficient,  I
think.

No absolutely not. That is how Steve Whitman took the high fore and aft
bending loads generated in the landing gear and fed them back into the
fuselage
structure. First the loads go forward into the apex of the two motor
mount
tubes and then back along the tubes into the fuselage. One must always
think about the load path.

Thanks for the great drawings.   I see it clearly now.    What was
life like before Rhino?   Jerry

Rhino certainly has improved the communications and made fitting everything
under the cowl a lot easier. I would say it could reduce the time required
to do a custom engine installation by one year.
