Steve Joblin:
some servos are pretty powerful, but they can also get expensive... for something of the size and weight you are looking for, I would go with DC motors.

What are you an avid Doctor of?

tomnt12:
sorry i meant an avid "Doctor Who" fan the british Sci-Fi Drama

benji:
cheap ones (10 $) gethya around 4 kg.cm

superchiku:
4 kgf / cm is quite a good amnt its like 40 N/cm so it will work
