I like it. I've always said if a prospective builder builds a kit or 2 from each manufacturer (IE Sig, TopFlite, GreatPlanes, Midwest, Goldberg, and a few more)... they will come away with so many techniques that will carry them through the hobby. Each kit and manual will have tips and techniques that are unique, and put them all together and you can build anything with confidence.

Great start with the Sig LT40. If those are built by the book you're nearly guaranteed a good flying plane... and it will get easier and better from there. Very nice thing about the Sig kits, for the most part they can be built with ordinary tools found around the house, and you'll get a chance to see what/where you want to go as far as tools and your shop as well.

A few other nice planes as you progress might be a Goldberg Tiger2 or Tiger60, Great Planes Sportster, or one of their Extra300's... depending on what type of building you find you like.. just a few thoughts, as I've built a few or more of these over the years and progressed from there (built a few dozen of different sorts since then..). Each kit I've built taught me something, and every one of them flies well.

Welcome to building!!
