The Webra ran fine on the test stand. I have not yet run in the plane.

I didn't let it get above about 8000 rpm on the stand with a 16x8 prop. I kept it at a rich 7500-7800 most of the time. Idle was impressive; it would tick over at just over 2000. Transition seemed fine considering that it is not yet broken in fully. There was minor hesitation, but nothing unusual. I'll tweek the low speed needle a little more when I run it in the plane.

Any recommendations on what prop to use for the first flights?
