Paul,  I want to contact Mazdatrix about the single rotor.  Who
should I address the e-mail to?  Also,  I believe what I want to
order is a balanced e-shaft and rotor combination.  That would take
care of it, do you agree?    I have two 13B I can rob for the rest.
The single will have a short oil pan.  I worry about taking an
additional 3.5 inches off for the S-beam.
I wonder if we could increase tank capacity by storing oil in the S-
beam?   It is just an empty box.   Jerry

Yes e-shaft, counter weights  and rotor  should do it.

It will get heavier due to no holes. Plus you have the plumbing
which is always a potential source of leaks. Other than that it should
work.
