The all-up weight is just under 8 #. I am going to inject glue into the spar area [due to experiences of J-3 and others] and I have added CA to the tall bulkhead that holds the front of the wing. I have load tested the wing and overall the woodwork, glue and covering are excellent. It weighs exactly the same as my blue Sig Kadet SR [dry] which has a Magnum 70 w 12 oz tank. Keep a close eye on that front bulkhead that holds the wing on, sort of a marginal design by Sig IMHO.
