I updated the web site to show Jeff's new PSRU
adapter-plate/engine-mount combo.
This is a bargain. It eliminates the Schertz beam which can weigh up
to 9 pounds and is also actually a couple of pounds lighter than Tracy's
adapter plate. Scroll down to near the bottom on the front page.

cosmetics of the engine installation. Real hi tech military look.

The pictures are of a slightly earlier version mounted on an RX8
p-port engine.

Thanks so much for the good word. I did not expect to see this on the
front page of your web..This could be the beginning of many quality
parts needed to get these engines in the air quickly.
again thanks and keep sending files.. I had C. Smith's Tracy unit but
sent it all back with his order..I now have nothing here to measure or
analyze .

Thank you Jeff. You solved a major problem because every Mazda installation
needs a good motor mount engine bracket. The Schertz beam works fine but it
is expensive to make and is rather on the heavy side. In part, due to it close
proximity to the exhaust, the Schertz beam should be made of 4130. This adapter
plate is removed enough from the exhaust where the aluminum is not a problem.

The Schertz beam gets expensive because it requires a large press brake to bend
up, lots of detail tig welding and lots of large holes made in the box beam sides.

The other major advantage of the plate is it reacts the 600 foot pounds
of prop reaction torque directly without passing it through the plate
spacers, into the aft end housing and then into the Schertz beam.
