  A while back I was playing around with CATIA working on an alternative
Motor Mount Idea for the Thrust Vector concept.  I was trying to move the
pivot point closer to the centerline of the engine. Now you have me thinking
about it again. what do you think?  Sorry for the .pdf it was the only way I
could get the screen shots small enough to email.

If you move the pivot point up there you will  have trouble stabilizing
the mount laterally. Joe Berki is having that problem as well.
That is why I put all those diagonal tubes under the oil pan.

There is another way of doing it with rubber ball jointed struts out
and forward to the spar.  Basically it is two tripods one on either
side of the engine. You may not have room in the cowling
as the thrust lines is much higher than the trailing edge.

A third way is use a structural composite cowl bath tub to hold
the engine. The Questair Venture is built like that.
The upper cowl adds torsional rigidity. This is the most elegant.

Then there is the four bar link with a virtual pivot.
