The thing that's suspicious is that 450 is the limit of rotation. I 
don't know which end of the movement potentiometer that represents, but 
you might have a loose position sense connection or dirty pot wiper. The 
controller would think it's not where it's supposed to be, and tries to 
move in that direction, eventually (hopefully) hitting the limit switch 
and stopping.

Is it otherwise reliable in tracking a bird during a pass? No jumps or 
other erratic movement?

Just a thought,
