Doc and Jerry. Here is the prelim design.
The tubes from the lower end of the nose gear socket up to
the upper hard points are the breakthrough feature. This
supports the nose gear socket from rotating clockwise on
a hard drop in landing and still provides plenty of room
for a large oil pan  and a radiator and oil cooler mounted
under the engine. The tubes from the upper end of the nose
gear socket provide lateral support for the Schertz beam
and prevent the nose gear socket from rotating counter
clockwise (side view) in the event of a pot hole type load.
The engine has two degrees off set to the right and a 2.85:1
gear box must be used with this off set.
Only half the mount is shown.

Any comments?

Here is with a nice wide rad and oil cooler combo.

Paul Lamar ...No rotor no motor.

I see a muffler (red), a radiator (transparent light blue) and an oil pan
(grey in mm1c, black in mm1a and 1b), but I don't see the oil cooler. Oh, on
re-reading the words,  I get it. The rad and oil cooler are one piece.

The exhaust pipe seems to be pointed forward which surprises me. Where does
it go from there?

The muffler appears to be the simple one. Is there room for the tuned
variety?

In mm1b there is a light grey cylindrical object with a red fitting on the
bottom with what appears to be tubing coming out or going in. This object is
located aft (near the firewall) and at the bottom of the engine. What is it?
Part of the fuel supply system?

The above prompts me to propose the following nomenclature. Use front and
rear/behind to refer to how the engine is mounted in the car. Use
fore/forward and aft to refer to how the engine is mounted in the aircraft
or marine vehicle. I suppose that even if this nomenclature is widely
adopted we will still have to add "in the car" or such like for those not
familiar with the convention. Sigh.

I am really delighted with your work and these drawings, Paul. If it weren't
for you I think that I would not even consider the rotary engine. This is
not to slight Tracy, Jerry and others who also contribute mightily including
all the builders who have gone before.

Doc

The part pointing forward is an internal cooling tube for the muffler.
The down pipe is not shown yet. Tunned mufflers have not been
tried. I expect they would radiate a lot of heat under
the cowl.

The oil cooler is along side the
rad on the right side of the airplane. About the same lenght
as the rad and about five inches wide. Stock 2nd gen oil cooler.

The light grey cylindrical object with a red fitting is a coolant
over flow container out of final position in the back ground.
Sorry.

It saves a year or two if one is able to do 3D's.
