Hi,
Have skins on the first two wing panels - top wing.
They weigh 85.5g
That's ;
Core - 27.5g (top wing)
Skins - 25g x 2
Glue - 8g - ; = 4g per skin.
There is some more sanding to do on the skins while the facings are being prep'd. So Maybe 80g equivalent is possible for these top panels.
The bottom ones will be 7g to 10g more.
A little concerned re finishing method after the discussion on the 'post a photo thread' just now.
Some quantitative testing req'd over the next few days.
