For just building kits a balsa plainer and sanding bars plus razer knifes /balsa saw and pins glue plus wax paper over your plans on a building board and away you go! Its the kiss method KEEP IT SIMPLE STUPID and i live by it. I have made alot of my tools over the years because iam so dam cheap . If i had that drill thing it would be taking up a good spot in my shop where a great tool i could use all the time could sit. lol BTW i have built in balsa all my life but have been building in foam for less than a year and its fun too. My own foam desighn taken from a 70's balsa one . It flew yesterday for the first time and it flew great,its a canard stick. Now iam going to build a slightly bigger one and draw up plans for dollar tree foam to be givin out free here on rcg. joe
