Fred,

After all, Thanks very much Fred for taking all this work on
writing with details all this tips. Your points of view are
priceless and makes a lot of sence, simple and precise details.

Its time to put in practice all said. As I can understand counting RPM
along all flight is very important, Its like taking a radiography of
flight. :) But... still I have to learn how to read all data,
understand what it means and how to do litle changes based on all that
info.


Right now im using your Excel program to practice some winding
and at same time comparing some different rubber batches. The
numbers (energy) I'm getting are far from the tests you have
done. I suspect im having problems reading torque correctly
because reading errors are +/- 0.01 in-oz.

For example, I'm getting averages 4300 FT-Lb/Lb from Tan II 5/99
and 3950 FT-Lb/Lb from SS 04/2006, so 5/99 has about ~9% more
energy than SS04/2006. Up to here sound reasonable, but im far of
reaching those 4700 FT-Lb/Lb you are getting. Dunno if im winding
too bad of if I measuring too bad..OR if this rubber is not so
good.


What torquemetertype you use? I mean, how much torque per
360 degree and how accurate is?
