Cac, close you eyes, imagine her and eagle, a live jet or stunt plane. Feel the wind, feel, hear her motor. Fly the bird!
There is a SciFi story, Equal Rites, where a seventh child of a seventh child thing turns out to be a girl and is turned into an eagle soaring over the country side. Or Atriiu[sp] from the Never Ending Story. Listen to her motor, and hear the shift points and get the timing right...but you have to do it by ear, by feel, no instruments for ya...

Pity me that the heart is slow to learn
What the swift mind beholds at every turn.
