I've posted this question a couple places but haven't got alot of info so I thought I'd ask here.

I'm trying to decide on an engine and it's between the Rotax 582 or the HKS 700e for an early Kitfox/Avid.

I haven't found any performance data for the plane with the HKS to help me decide one way or the other but I like the reliability of the four stroke with the long TBO and the lower fuel consumption.

Anyone have some input, good or bad to share?

btw this plane has extended speed wings.
