And yes it is the Sandwich lol. But I do not feel I will build like that again took too much time to do so. Next time I will just use sticks and sheeting and save some weight. I was at a loss for words when my WASP came out to 3 pounds 11 oz I thought for sure it would have been lighter. Since I did cut everything lol.. Heck even the ribs have no ribs inside hardly just a 1/4 around the outside and a half inch piece between the balsa spars and everything else is built out of square stock.
