My students would beg to differ with you on that.

Also, yes, a 1 second lift is unlikely. Mostly because gearing to max power means you stall your motor if you double the load. But c'mon. Aiming for a paltry 12.5% stall torque on a CIM still gets you from 0-20 in under 2.5 seconds. 5 seconds just to lift yourself with a CIM means you're doing something wrong. Using a different motor will obviously be slower, of course. But still, it's just 20".
