Motor specs

+Frederick Deryckere  over @ man made mahem found the vendor and specs for the motor.

From his blog: "After a while though I got lucky and stumbled upon the website of the original manufacturer of the motor: http://www.baolongmotor.com. In the end, the ‘dragon’ logo was a dead giveaway. I contacted their support team, and they proved surprisingly helpful. Below is the spec sheet they sent to me, accompanied by the sheet of the replacement motor I bought (not from them ;-)). Seems close enough to me."
