Hi All,
I have a brand new 300A Lite Swordfish ESC. What happens is when I connect it to any motor with any battery or radio I'm getting pretty severe cogging in the motor for a second or so before the motor runs smooth. However, many times the motor cogs badly and simply stops. The ESC has done this from new straight from the box. Pretty happy with my solder jobs and connectors but am in the process of redoing them nonetheless. Pulled the shrink wrap from the unit and couldn't see anything untoward. Connecting 6S through it only at the moment with an additional 35v 6000uf cap bank. Motors tried have been Nue's (1521, 1527) and Leopard 1600kv. All suffer the same thing. This is bench testing only I might add.
Can anyone shed any light on what might be going on here. Dead ESC????
