I have been building model airplanes for about 40 years and have built every one that Guillows produces. I would recommend them to anyone that would like to get into building. The balsa is good quality,the plans are great and they have step by step instructions for the beginner. I usually just build them and either hang them from the ceiling or put them on a shelf or build them and then give the finished product to someone I know that likes the plane. Usually my dad. When I can get a child interested in modelling I teach them as my dad taught me.
