That's the 2nd time that what I would consider a top flyer or top designer has talked completely differently about weight in a ship depending on where it's placed. Hmmm.
The following is cut-and-pasted from RCgroups. It is written by Mark Drela. Maybe this is what you remembered:
--------------------------------------------------------------------------At the tail, and especially at the wingtips, the main concern is yaw inertia.
For example, if you add 5g to each wingtip, you will... Increase weight by 0.7% Increase inertia by 5%So it really does pay to shave grams at the wingtips. As a reward you will get a -glider which handles better and signals lift better. --------------------------------------------------------------------------
