Ron,

The fact is, Diamond initially sold the Katana with the Rotax (DA-20), then
apparently offered a upgraded 100 HP Rotax conversion (DA-20-A1), then finally
abandoned the Rotax for a Continental in the DA-20-C1.

Yeah, but why? Pure market acceptance problems in the US. They continued to sell
the Rotax variant in Europe.
