Hi Peter
Please correct my math... sink rate of 350'/min @ 87kts gives a glide ration
of 25:1... Something must be wrong with my calculations...
That surely is as good as many gliders??
How's the weather? I should get there Sunday later in the afternoon am
getting excited.

Jerry and all,
my Classic Mono, with feathering Airmaster prop and two up, sinks at close
to a 1000' per min. with the engine off. When feathering is complete the
sink-rate settles at 350' per min. at 87 knots and the glide ratio is
considerably better than some of the gliders I used to fly in my youth.
Mind you, an engine failure shortly after take-off would not leave time for
anything other, than getting the nose down and looking for a suitable place
ahead. I have not tested the sink-rate or glide with flaps and gear down
yet.
BTW, we did not bother to re-start the engine and slipped off the excess
there is nothing wrong with your math, Tom, there is usually some lift
where we flew, at least part of the way. I fully expected to have to
re-start the engine. We'll try it again and you do the flying! It is quite
amazing what the Europa can do in the clean configuration.
The weather turned nice in the afternoon after a drizzly morning. Sunday
should be similar and Monday and Tuesday are predicted to be better. We'll
have enough flying to see you through.
Looking forward to seeing you!
Peter
