The VAPOR weighs 17 grams ready to fly (60% of one ounce).
If it weighed one ounce - and had 144 sq inches -
it would figure out at - one ounce per sq ft
N/Y?
my math was done in my head ( SWAG)
I was going to try for one ounce.
This little bitty stuff is a real challange -
My UMX300 weighs 32 grams and the wing loading is higher than I would like.
