OK folks, some comparative weight data WRT the Poly prep method....finally.

You'll recall that I listed the following starting reference weights back on page 5 of this build.
-Fuse (minus belly pan, motor, and nosegear) = 562 grams
-Single wing panel including aileron (no gear or servo) = 205 grams
-Stab half, including elevator = 72 grams

Now that the aircraft is ready for paint, I weighed the same parts again to see how much weight was added by the cloth and Poly.

-the fuse weighed an additional 127 grams
-each wing panel (w/ail) weighed an additional 48 grams
-each stab (w/elev) weighed an additional 16 grams

Therefore the overall weight gain from this prep method is approx 255 grams, or .56 lbs. I'll re-weigh one last time after the paint has been applied. Should be interesting.

O'Kelly, thanks!!
