Harry: Before you buy the new Ultralite version of Choppy, take a look at
the gross weight, 254# +360#= 614# to meet the normal rule of thumb of
10#/hp the Ultralite would need in excess of 60hp. Now the coning angle
of
the blades is designed based on max gross wt and rotor rpm. Of course the
hp and rpm required are based on the lifting ability of the particular
blade
airfoil and whether there is a linear twist or not. One of the things
that
I have not seen at any of the 13 events that we cover each year for the
past
8 years, is any ultralite helicopters other than an Ultras****t and a
Mosquito. One thing to insist on for the advertised claims: Show me a
demonstration. It is easy to produce specifications on paper and another
to
actually have a flyer that meets those specifications.
My Safari weighs empty 1,000 #. It's payload capacity is 500#. If it was
easy to pickup 2,000# with the Safari, I'm sure the kit manufacturer would
do it.
