Okay, this may come as an ignorant question....I've got one of these kits, and the instructions provided have twice told me to reference the included plans. The fact is, there were no plans in this box brand new from Sig. I've since built the aircraft, straight and true, but do I need to call them so I can retrieve a set or were they just never included in the first place and the instructions assume that everyone knows how to essentially build without a set of plans?
