If anyone could help here I would be grateful. What exactly do you look for in an electric motor besides brushed andbrushless?I have a couple of them, my father gave them to me, they are brushed and they have various verbage printed on the side of them. I'm an electroinics technican for the Coast Guard and am used to seeing specifications written in Volts, Ampheres, Watts, Ohms, Hertz, Farads, etc. However I am not seeing anyof those measurment designations on the side of the motor. How can I figure out what size motor I need, as well as what ECSand battery, for the various kits that I may purchase (as kit building is what I would really like to get into)? Is there a mathmatical formula (I like math) for figuring out what size motor/ECS/battery you need, based on whatthe motor specificatons are,to effectivly power a plane of X weight and Y wing span etc.? Thank you all in advance.
