We think they will enjoy the hobby more and have better long-term success if they work their way up to those big projects by building some simpler FF or CL kits first. Check into the designs shown on this page. With these economical kits, novices can learn building techniques, become familiar with flight trim reactions and develop engine starting skills. As you progress to more in tricate models, the Sig line includes many other airplanes that will fill just about any requirement.
