Ask Question
looking at the X2 and regular version of the 3674 2650kv motor. X2 has max V at 3S - 11.1V , the regular 1 is at 6S - 22V. Info correct?
A:
Those are the specs listed by Leopard, we did double-check. It's important to note that a motor can still overheat to the point of destruction of over-geared even when running at or below the maximum recommended voltage. Proper setup and monitoring of temps is critical: https://www.rcjuice.com/power_system_setup
