Dear Kevin ;

Thank you for your reply.
I have bought the Twinstarr manufacturing rights, all tooling etc..
We have made an ultralight version of the Twinstarr, called the Twinstarrlite, which meets the stringent European ultralight rules.
The machine is now a lot lighter and handles well. In order to make other engine option availabe, we are loking intensively at a single rotor Mazda
aplication, in the knowledge that the Norton rotary is too expensoive and apparently had some shortcomings (at least the earlier version).
I hope somebody can help.

I heard years ago that Atkins rotary made a single rotorversion out of a 13B, but it produced only 90 HP . I think nowadays with the 20B , fuel economy as
well as output may have been increased.

Sincerely,

Woody DE SAAR-- 

Unless Richard Sohn gets his two piece alum/cast iron end housing in production a 
one rotor will weigh with PSRU about 200 pounds. Unless you go to peripheral ports
or a turbo charger 90 HP is about all you can expect out of a one rotor.
