he fellows,
i recently got my alias out of hibernation. was thinking of upgrading the motors.
can someone tell me what the difference is in their (traxxas), high output motors &
the coreless motors from Micro-Motors i`ve seen for it? the coreless ones from them had reviews of only 6 hrs. of like to them.

is there an explanation of the difference between the two & why i should buy one than the other
if i decide to change them?

thank you for your time!
