Umm, Dave,

Where'd you get that 1200 fpm climb rate calculation? I think you forgot to
factor in some things... like the prop efficiency and the (flat plate)
drag... :-)

The problem is that 18hp gives you a rate of climb near 1200fpm.
(they all do that don't they???;-]) To drop the climb rate down to
reported
figures then 300-400fpm then it would appear that it's getting a
thundering
10hp into the air and would need that .85 fp to see the speed.
