Default Measurement of CofG

Thanks for a good technical reply.

Now I just have to check and see if any of my measuring devices have
decimal
inch/cm graduations. Seems most are graduated in 1/16th, etc... Let/s
see... That would be 200 inches long and 2 and 14.4/16 inches high. Oh,


crap! There's that pesky decimal again. I know - I'll make my triangle
2,000 inches long and 29 inches high! Now, if I could just find a surface


on the glider where I can make that fit.

Really, how accurately can you measure 2.9 inches, mark it, and cut it? I


don't have a machine shop. This all reminds me of the old Air Force

adage:

Why would you want to use inches specifically? the ratio 2000:29 could be
inches, millimeters, bananas or ay other unit you might wish to use, that
is why it is expressed that way, works whatever system of measurement you
care to use. A distance of 10000mm with a drop of 145mm would seem to me
pretty easy to set up.
