Our 256:1 drew 1.0A under no load at the most new and lubricated time of its life. 1.0-1.3A is definitely a good number. I'm not sure why the 2005 motor spec sheet has such high no-load current draw numbers.

Whoever on your team decided to buy so many spares should get MVP this year. We have just one. Luckily, it has survived okay so far. I thought all I had to worry about was the carrier plates. Now I have to think about gear teeth being stripped too?
