Paul, With ALL due respect, what am I missing? It seems to
me that you have been preaching the necessity for lateral
bracing with triangularization for motor mounts. Are my
eyes deceiving me, have I totally missed the message, or
is this a trap? I have waited as long as I can for some one
else to bring this up but I can not see any lateral bracing
in the attached JPG.

The lateral bracing was hidden in that picture :) Sorry!
Here are some more pictures.

I am not happy with the rear mount as shown and that will be modified
slightly. I will extend it down to the tabs on the oil pan
and use rubber isolated ball joints. The angle of the down thrust line
is adjustable to optimize cruise or top speed. Your choice.

In case you are wondering the rear panel on the custom oil pan
is 3/16 thick. I don't I don't feel a single ear on the Mazda front
cover is strong enough. You could build a bracket that picks
up both ears as Bob White has done if you don't want to go the
custom oil pan route. Let me know if you want to see some more
examples of this style mount as Jerry Hey as made several for
several different types of airplanes. These are rather easy
to build and are of modest cost.

Here are some pictures of Bill Schertz's similar mount using a beam under
the oil pan on the flywheel end housing instead of the motor plate. 
Now known as the Schertz Beam.

The clips were added to accommodate gyro loads from the prop.
Bill do you have a picture of the latest config?
