Does this mean to make a plane do an upright flat spin, the only difference is to give the plane full up elevator?
Yep, usually. Strangely though, it doesn't work that way with the MAGIC, a high wing fun fly plane. If you hold UP elevator, LEFT aileron and RIGHT rudder, it will enter an inverted spin. I thought it was weird the first time I did it. I was expecting it to be uprihght. Instead it entered and even flatter, sort of tumbling flat spin. It works every time. That "UP elevator, LEFT aileron and RIGHT rudder" spin entry has become my preferred way to spoin that particular plane.
