RE: Sig LT40 or GP PT40 for first build in ten years?
I doubt you could go wrong either way to be honest! i have had experience with the LT-40 and it is a great flying and very durable airplane. Also it is is very easy to build as well. I am not 100% sure but I think the new kits come setup as a bolt on wing now, we made my sone a bolt on wing and it (an me) taught th boy how to fly, my frined also built one have never built any airplane before and he did a good job and learned how to fly on it. I still have the airplane here and am thinking about cleaning it up to sell cheap so someone else can learn how to fly. Either way you go, you cant go wrong!!!! thousands have learned how to fly on both airplanes. I found the LT-40 to have a great hardware apckage but I dont think it had the tank etc. Good luck.
