Is there an advantage to building a second wing for my trainer (LT-25, I'm building it stock) vs. just flying the wazoo out of it then getting a second plane? I'm planning for a low-wing plane next (HOB Spacewalker, Sig Astro Hog, or the like) but not some crazy 3-D or ultra-aerobatic ship. I suspect that a wing kit for the LT-25 will cost nearly as much as the HOB Spacewalker anyways, so it's not really going to save me much money...
