    Got the motors today upload_2019-9-28_20-18-49.png upload_2019-9-28_20-19-24.png

    Punched the rivets out of the gearbox and used a hole saw to cut hole for the shaft on other side of gearbox and made into lefthand box. Metal gears looks solid no backlash.

    I should have ordered left and right hand gearbox in hindsight. :)

    Open gearbox - brass gears is a good sign.

    Mounting motors and turning arms - checking motion limits, roll 12 deg, pitch 8 deg.
    Not sure if this is normal?
