Paul,   I am going to attempt to send JPEG renderings of some of the
 aluminum side housings. I also did iges in solidworks surfaces style and
 stl
 which I hope to give to you if you get to sun-n-fun also there are 3Dm
 rhino
 files, with the curves used to generate the parts to allow changes. This is
 about a third of the rendered immages. I can send a few more tomorrow. I
 haven't done the replacement wide housing for the three rotor which is a
 two
 piece "O" ring sealed part similar to the center housing except with oil
 galleries and a stationary gear. I am waiting to see if I can spec a two
 rotor front stationary gear since the flange will be inside the housing.
 There is a total of 21 pieces to do one thru four rotor and with the wide
 center housing six rotor configurations.
         I didn't  get some of the interesting bits on the attachment list
 and can't seem to delete them so I will just send it and have to do a
 second
 list later.

 Looking good George. I am sure glad you got into Rhino. Now we can talk :)

 I guess the next thing after I get my plane flying and my oil well comes in
 is to work on getting this plane a bit lighter. Right now, I've got two fuel
 pumps, at about ten or 11 lbs each, two batteries at 13 lbs each, my coolant
 lines are a total of 12 feet long and 1 1/2 diameter, I could save half
 their weight by going to 1" inside dia, lighten my solid aluminum ingot of a
 shertz beam, and think about things from there.

 If I had some big money, I'd build up another engine with peripheral ports,
 thus lightening up the intake manifold by around half, and get aluminum side
 and middle housings. How they wear isn't really of any consequence because
 that isn't going to happen anyway, at least not in the forseeable future.

 But I am going to try to take at least 70 lbs off in the next few years.

 I would not reduce the size of the water pipes.

 Paul,   I stacked up the aluminum side housings designs into an engine to
measure how long the 4 rotor will be and check cowl clearance requirements
and thought you might be interested in what it looks like. I am short on
computer ram so it is shown as the front 2 rotor section and an add on back
two rotor section. Any 4 rotor combination is the same length of 35.2545"
from the face of the PSRU plate to the front accessory cover mounting
surface. I started on a 20B type housing today that uses an RX7 front
stationary gear for a 3 rotor or two of that same gear one forward and one
back to be a center housing for a 4 rotor with RX7 intermediate housings
between each pair of rotor housings. The length of a two rotor section is
the same as stock except that the PSRU spacers are eliminated with the
extended bellhousing flange.
