Well packaged and mint condition DC motor
Just received the pair of motors in the mail. A part the duty tax to pay at custom the packaging was secured and items inside ere not damaged.
Received extra part to assemble but I ould have liked to have a nice little panflet maybe inside to give more spec on the motor like what size bolts, nuts, fits on the shaft or even the mounting on the motor so I dont have to search.
Overall will be testing these motors very shortly,
