"The motor has 70 in-lb thats not no power. We are looking at it through a 10:1 Gearbox to get some power low speed from it."

The 70 in-lbs is the stall torque at zero rpm. You should plan to use half of that if you want to do any useful work.

The free speed is already only 100 rpm. With a 10:1 gearbox that's down to 10 rpm max (or 1/6 rotation per second). At half load speed your looking at closer to 1/12 of a rotation per second. Probably way to slow to climb with.
