And they all lived happily ever after...

Heres a question then, and a good one at that (rare for me...); just how much torque do you really need to turn the rather small and lightweight wheels of a 1/8 buggy?

I have a pair of 645mgs in my 13lb truck, turning 1lb tires- thats about a total of ~250in/oz of analogue torque ( :P ) turning 2lb of rubber, and it does so pretty well.

Do we really need 200-300in/oz digital servos in 6-8lb buggies, turning tires that weigh... not very much?
