Re: How many seconds to climb the rope?

I think why you are seeing such long climb times is that you are not properly gearing your CIM/mini-CIM motor. Remember that a motor's maximum power output (watts) is usually roughly around 50% load. Not accounting for friction and other factors, one should be able to climb in 2-3 seconds with only a mini-CIM -- at least according to our calculations.

For reference, we are using a 1 3/4" winch with a 20:1 gearbox and a mini-CIM. If this isn't fast enough, we can easily upgrade to a full CIM.
