A simple way to get mostly accurate results is to use the potential energy gained at the top compared to the power output of the motors.

Gravitaional potential energy: mass*gravity*height (mass*gravity=weight)

Once you know the potential energy you have, you can divide it by the power output of the motors, and it will give you the time it will take. I would add about 20% to that time to give you a buffer zone aswell. Power ratings for the motors can be found here: http://www.chiefdelphi.com/forums/sh...ghlight=tetrix

Speed calculations are pretty straight forward, and I would assume you know how to do them because you should use them for your drivetrain as well.
