Both your question and level of experience with HV products are far above my pay grade.

However, I was wondering about the max rpm rating. Given that the 4.5 motor is used on 4s lipo or 12 NiMH cells, and it is a 5,000kv motor, that would place total unloaded rpms right around 74,000 rpm.

Also, if the max rpm is the same for the 4.5, 5.5, 6.5, and 7.5 motors, does this mean that the 7.5 motor (kv=3,000) can conceivably be run on 6s lipo or 18 NiMH cells? Obviously a different ESC would need to be used, and careful gearing would be necessary.

I posted this question at RC-Monster.com (http://rc-monster.com/forum/showthread.php?p=297749) and "NovakTwo" suggested I contact you.

Thank you for your time,
