I thought the 601 was a rotax/jabiru type of machine.



The Rotax, Jabiru and O-200 were all FWF options that the factory
directly supported. They now list the William Wynne Corvair conversion
on their website and have had his plane at their booth at the last two
OSH and SnF shows.

In fact a guy recently had the DAR inspect his Corvair powered 601XL for
an E-LSA certificate and was given only a 5 hour phase I test period
because he felt that it was one of the engines that the factory suggested.
