15 years ago when i was first looking into the hobby, buddy cords either didn't exist or were not the norm at the flying field I had access to. The instructor would take the tx, fly the plane "3 mistakes high" and hand the student the tx, taking it back if the plane was low and in trouble, or when it was time to land. I'll be using my old old futaba AM radio in my Kadet LT-25, and unfortunately I don't think it's compatible with modern FM transmitter buddy cords. How much of a disadvantage am I going to be at in this world of buddy cords if I need to use the older "quick, hand me the transmitter" method?
