From Bruce's long hocus pocus post I can see he is still drinking and has
not gotten the grasp of what has at all been said about the stiffness
testing and the adjustments I made on the program I use and distribute. Even
more interesting I have received an e-mail from one of the recipients of
Bruce's "White Elephant" TWIB sale and this particular proven world class
flier (yes Bruce there are people out there that through their
accomplishments have proven to have a more valuable opinion than you) said
"Not sure at all what he didn't like about it. It will appear in a F1D
soon.". So this is another case of REAL WORLD feedback not matching your
twisted ideas.

Bottom line as pointed out by real live engineers that are on this list is
the stiffness factor is merely a helpful scale and as long as you compare
values generated from the scale it does not matter. As I have plainly
explained many times we individually test every sheet. We have taken the
range of values we see using the calculator I modified and broken it into
ranges of good, better, best. Then price the sheets using a formula that
factors in width, thickness, grain, and stiffness range. The difference in
price between 2 adjacent stiffness grades is $0.30 - $0.50. So the incentive
to discredit the product by is small. In addition Bruce's crazed balsa
busting has not at all addressed the fact that a sheet we mark as "Good" is
not as stiff as one we mark as "Excellent".

Regarding Bruce's contention that the modification had nothing to do with
thickness, he is once again purely full of shit. I added to the formulas
math a piece of logic that says if the balsa is over a certain thickness
then multiply the stiffness coefficient number by a factor that increases
with the thickness of the wood. Very clearly the math is based on altering
the results based on thickness. As I have pointed out to anyone that cared
to ask this was to make the results more closely model the real world. I was
even conservative in this factor in that if I cut sheets from the same block
varying from .020" up to .125" grade them out to all be the same density and
then compare the resulting SC of the calculator, the thicker wood still goes
down in SC a little. So once again we have talking out his ass and telling
me that an adjustment I made based only on thickness has nothing to do with
thickness. More shit for a proven bull shitter.

Bottom line is the vast majority of the indoor community understands what I
am offering and the value of the ratings. Fliers around the world keep
buying my wood and using it in planes that set records and win contests.
Bruce has for some reason decided that trying to discredit my product and
accuse me of being a crook is somehow a good thing. Guess when Bruce starts
offering a competing product we can all see if he has any clue. In the mean
time I will continue to offer my product exactly as I have in the past. If
you like what I offer buy it, if you don't then get it from someone else. In
the mean time if you want advice on building a plane from foam, Bruce sounds
like the man to talk to if you can catch him when he doesn't have his head
up his ass.
