The two-stage gears are made in one piece, so there's no extra parts, but you have two surfaces to share the load, so wear should be lower.The main reason that I object against motors like the Q128 is their double stage reduction gear. It's kind of the same argument with Hall-less motors, fewer mechanical parts is more in reliability and cheaper maintenance.
That's a very good question. I'm still trying to figure it out. I guess you mean if they both have the same current, voltage, controller, maximum speed and actual speed. They both have the same reduction ratio (AFAIK) and you can't get something for nothing, so logic says that you can only get more torque if one has a higher efficiency than the other. Without figuring out all the ins and out, I'd say that the outrunner should be more efficient than the inrunner, so I'd say yes, but not by muchDo you think the torque will be about the same as the q128c D8veh?
