I weighed the two wings...

They are both a tiny bit on the heavy side... particularly the Fun Fly wing which when produced from the revised kit bits will be a teeny bit lighter....

Both wings have JR591s (ugh), and 3mm pushrods, and M5 steel wing bolts in place at time of weigh in.

Aero Wing weighed 530 grams : 18.5oz
Fun Fly wing weighed 490 grams: 17.2oz

My scales are digital but they aint great... but this seems to be about right I think
