I am building a balsa glider from a 1961 Flying Model article/plans. It is the Nomad designed by Ted Strader which I have enlarged from a 48" to a 64" wingspan. I intend to power it with an electric motor mounted on the pod above the wing. I know little about electric power other than I need a motor and prop, esc and batteries. What I need to know is what kind, size, and where to buy of all of the equipment required. Your help would be appreciated.
