Paul, I think you are wrong about being able to remove the PSRU from
the motor plate with the motor mounts on it. You just undo the 1/4 " bolts
instead of the long 10 mm bolts. To inspect the psru you must remove the

1/4"

bolts anyway. I have done it many times. Here is a pic with just
a couple of the 1/4" bolts holding the psru to the motor plate.

You don't necessarily have to use the motor plate for the mounts.
You can use a Schertz beam and motor plate and
all will come off with the engine still in the mount.

Hi, Paul....you are correct that the system depicted in the picture allows
removal of the PSRU without removal of the engine. What I was referring to
was the original drawings that Jerry Hey did for me in an attempt to make a
mount for me using my Ross PSRU. He proposed welding the mounts to the PSRU.
That would have made removal of the Ross PSRU difficult.  With Tracy's
redrive and the present system, removal of the PSRU would, of course be
easy.  Unfortunately, I needed a motor mount before the later refinements.
Again, it's great that we have all these experimenters who make it easier to
turn our rotary engines into "plug and play".  Especially admire your
efforts.  Paul Conner

I guess you missed the few years of the newsletter when the original
idea of the cross beam was proposed and extensively discussed. The 
Schertz beam was an extension of the Questair Venture idea. It would 
work fine with the Ross. the pictures have been on the ACRE NL web site
since the beginning almost five years ago.

How much did you pay for your motor mount?
Please inspect it very carefully for cracks on a regular basis.
