just picked up a izip motor from ebay. It runs ok when connected to a battery and controller.
I noticed when I turn the motor cog by hand (not connected to a battery) it makes no noise clockwise but counter clockwise it sounds like I'm winding a clock.
I've got a second spare motor and this does not happen on that motor when I turn it by hand counter clockwise.
Both motors run fine when connected to a controller and both look the same physically. I just wondered why one make that noise?
