For those who do not know the history:
The Sunbird S-1X was designed from the ground up by Dan Rihn using the ideas of the Pitts S1 reimagined for higher performance
and engineered to accommodate the Lycoming IO-540 engine. It
was designed to compete with the high performance monoplane
up to the Ultimate category which it does well.
