I just purchased a used fantom ion v4 (D3.5) 7.5 motor off of here and upon inspection noticed that the rotor had no balancing putty. I have never seen a trinity rotor that didn't have balance putty on it yet there are no gouge marks from removing putty which makes me believe it never had any. Any thoughts on this rotor issue?

May have been born good enough as to not needing any balancing.

If it had come off, it would've damaged the motor. If it runs well, don't worry about it.

You could check the balance with 2 razor blades. Take rotor out and place the ends on the razor blades and see if it is balanced.

I wouldn't worry about it too much, but you could always check it. I used to balance check my trinity rotors, and even with the clay, they were terribly out of balance.
