 You are correct, just should have kept my mouth shut. I don't do business 
with Fred Sage anymore. I like to have a manufacturer that
 will not take a planform that is provided to him and sell it to customers 
direct. I don't think that is too much to ask.
  My apologies go to anyone I have offended.
  
How about knocking off this childish crap Sal, then you won't have to 
apologize.  You always have to put someone down in an attempt to justify your 
business ethics.  IMHO   Bill Grenoble

Fred, I did not say you copied the laser planform for the Addiction. I do know
that you have made copies of the wings that we make for other pilots.

FRED SAGE wrote:

 I haven't weighed in on the thread concerning the Schpot Dorker being a
 clone of the Addiction because I thought the allegations didn't warrant the
 dignity of an answer. I know Daryl Perkins is a premier pilot and glider
 designer and certainly doesn't need to copy an existing design to make a
 marketable glider.  The truth of the matter is that both the Schpot Dorker
 and the Addiction are fine examples of light weight unlimited designs that
 are optimized for typical AMA thermal duration tasks.  Either glider is
 capable of winning with the right pilot at the controls.  However,  a pilot
 that wins with either glider is probably equally capable of winning with any
 number of alternate gliders.

  After reading Sal Defrancesco's recent post,  I find that I can no longer
 remain quiet.  Sal states that I copied the Laser 3MC plan form as the basis
 for the quad taper Addiction.  This is simply not true.  First of all,  I
 offer the Addiction in any number of configurations including double, triple
 and quad taper variants.  In addition,  I allow a pilot to select the span
 of the glider he wants  from a minimum of 112" to a maximum of 125".  In
 other words,  the wings are custom designed to customer specification
 depending on the proposed use and skill level of the pilot involved.
 Furthermore,  I offer the wing in multiple airfoils including the 7037,
 7035,  7036,  7035,6,7 blend,  RG15,  SD7080,  RG15,  etc.  When I take an
 order with the span and  airfoil stipulated,  I simply run the numbers
 through John Hazel's fine plan form optimization program to achieve an
 efficient wing.  I'm able to do this because I've been accumulating
 templates for about 10 years and am not constrained by the restrictions of
 production work.

 The real truth of this "who copied who" scenario is that as gliders become
 more optimized around a particular design parameter (light weight three
 meter thermal duration optimized),   they become very similar.  Given an
 airfoil,  wing loading and aspect ratio,  panel breaks and taper ratio's are
 going to be almost identical.  Does this mean that one glider is a clone of
 the other?  Certainly not.

 As a final statement,  whenever inflammatory opinions or derogatory remarks
 are made on the RCSE such as Eric Farmer's post of three days ago or the
 post that prompted this response,  the logical consideration should be to
 determine the motivation and credibility of the drafter.  With a little
 common sense and reading between the lines,  the truth becomes apparent.

Funny, I didn't know that there were any copyrights on airfoils, dimmensions or tapers.

Sal, do you think you can jump high enough to get both feet in your mouth? I 
don't think I ever saw an apology with a right hook attached! Just my 2

2000-05-06 Thread FRED SAGE

Sal;

I don't want to argue semantics with you on such a public forum.  If you
want any further responses from me on this subject,  you'll talk with me
personally,  either via e-mail or by phone.  However,  to refute your post
of earlier this evening,  what you actually said was "The Laser 3MC was the
first quad tapered wing designed and now copied by Fred Sage."   Since I've
never copied any of your products,  I still take exception to that
statement.  What I do when taking an order from a potential customer is to
spend several minutes talking about  his background,  experience level,
geographic location and objectives for his new glider.  Depending on his
answers,  I'll make recommendations involving airfoil,  plan form and
wingspan.  The customer then picks and chooses from the various design
compromises involved with those decisions.   In this manner,   I can deliver
a custom glider that will give maximum satisfaction to the individual
customer.  There's no copying in this process unless you consider NSP the
sole proprietor of the quad taper wing.  Please Sal,  may  I have permission
to develop a quintuple taper wing?  No matter how many tapers are involved,
I do use John Hazel's excellent plan form optimization program to ensure
that I build an efficient wing.  If my wings turn out to be similar to
yours,  that just indicates we're both proceeding toward the same goal.

In case you're interested,  of the 67 e-mail responses I've received either
over the RCSE or personally concerning this thread,  only one differed from
the majority opinion.   Although I'm too much of a gentleman to point out
the obvious,  I'm sure you realize which side of the disagreement people are
supporting.   The overwhelming preponderance of the numbers  tell us to give
up this futile discussion and turn the band width over for more productive
use. Perhaps we should listen.

Fred
