I just made a set of winglets using 7725 and a core material called
Soric SF. I used the resin infusion process. The other day I bonded
the skins together and a few days later, with much excitment, I split
the molds apart and liberated the parts.

I gotta say, these are some nice looking parts, they are incredibly
stiff even prior to the spar being added.

Here is my question. These winglets include the transition plus the
blade, and right now w/o the closeout rib, spar tube and other doo-
dads weigh less than 2 pounds.

Any of you guys with similar topology winglets know what yours weigh?
The LS-8 winglets come to mind, as well as the DG-300 winglets.

Thanks!

FWIW
My ASW-24 winglet, 20 inch span, 5 1/2 mean chord, finished with root
rib, mounting
pins, etc come in at or below 15 oz. Contact me privately if you wish
to share.
