Hi Wayne ! It looks like the Langley Vamp got a makeover . It was looking a little rough when I climbed over it with my camera a couple of years ago. I had some isues with the parts fit . A few of the laser cut parts where not the same as the plans . Some of the stringer notches where not correct and one former was not high enough on the top so I had to build it up to allow a smooth curve . I'm away from home right now so can't give specifics. There are a few outline inaccuracies that I'm trying to correct as well . For anything other than the MK 1 , the stab chord needs to be increased by 0.9". When I get back home I'll give Sierra another call . It's been "next week" for months now !
