Product review (3 stars): Good standard motor, not equipped for combat
I used these in a 2S Antweight combat bot.  The speed is ok, definitely not slow, not super fast.  One of the gearboxes stopped working after a few fights.  I haven't taken the gearbox apart yet to see if it is fixable or not.  I'd recommend these if you are in a time pinch.  Otherwise, stick to Fingertech or other motors that were made with combat in mind.
