Theres an SAE paper you can purchase, $9.95 i think, that explains the use of radio tracers in tracking ring rotation. I havent read it in about 8 years so i dont remember all the specifics. I just remember reading the top ring spins faster than the 2nd ring, about 6 times faster if memory serves. I also dont remember how "broken in" the motor as and how many pulls they put on it to track this.

seal.... I'd like to know the WHY part... I've heard
they turn(I still dont know for fact) but if they
do then why
