Robert,

Where in the world have you found an R-680 powered Twin Beech? That
has got to be an incredibly rare beast. I thought only one or two of
the very first ones had other than Pratt and Whiskey R-985s. The
early ones were much lighter, but, still, the performance had to be
marginal at best.

Have you ben able to get your hands on a manual for the R-680 powered
model? Given that it would have been written in the 1930s when most
manuals were pretty basic, I'd be curious what it reported about
performance. Does the airplane even have feathering props? What is
the serial number of this airplane?

All the best,
Rick

Does anyone have time in a R680 powered Beech 18? If so, what sort of
performance numbers are they capable of and are they reasonably safe on one
engine?
