I have built the Sig LT-40 from kit and it is a very nice building kit like all the Sig kits I have built except for a couple. The Sig Citabria kit is not for the faint of heart and the Sig 1/4 scale clipped wing Cub can be a good challenge, but all the updated newer kits from Sig all build very nice and something like the LT-40 kit would be an easy first build for anybody wanting an LT-40. Goes together very nice with great instructions.
