Yeah, I had a set done for my Arrows, and they were $86.26 including shipping. They have to do them in three sections because of the extreme taper in the wing, so there's three times as much machine time as a conventional wing. I'm glad to have them, tho, as the built up wings were always getting such a beating in the water.
Anyone who doesn't want to pay that price could always order the plans for Laddie's Arrow from RCM Plans and make the built up wings. They will come out about 5-7 oz lighter than the foam core ones. (I used finishing epoxy to bond the 1/16 balsa skins to my cores is probably why they came out a little heavier. After much bad luck with contact cement, I wasn't willing to use anything else.)
