I'm more than leaning - I'm completely tipped over! I installed my
rotary engine mount from Conversion Concepts a couple days ago and
pickup my rebuilt 13B in a couple days!

Still have to work out all the plumbing in and out!

Thanx,

Paul,

 In early August you suggested Paul Conner send his SQ2000
motor mount back,
suggesting it was going to fail. That engine mount looks like a
Conversion
Concepts mount. Care to elaborate?

Conversion Concepts changes their design with regularity. I have not
seen the latest. If Joe Hull sends me a picture I will comment.

 Well Joe, how about it? I would think that the canard community would
be very much interested in this.

You can see lots of photos on the web site:

OK I will assume these are the latest.

First problem.
This problem jumped out at me when I just accessed the web site.

When they calculated the CG by NOT including the 8# starter and the 30# prop
the CG on the engine is further forward (pusher) than it is in a real
installation. This erroneously made the the four mount system that they
use look better than it really is. Very clever or dumb depending
on how much credence to their motivation you give them. The real 
engine CG is further aft in a pusher installation. About where the
rear housing is located. Honest mistake? Perhaps!
