Re: motors/torque

Then what do you recommend?? What kind of torque is needed to turn? I know torque is 
based on motor design and voltage adds rpms. Though bumping up the voltage usually 
increases torque due to the extra power available. However 24v requires very large 
batteries and you lose ALOT of capacity. For example a 24v SLA and a 12v SLA can be 
the exact same weight but the 12v will have almost double the capacity. SO I should 
try to find a VERY strong pair of drill motors...right? I DON"T KNOW...argggg.

Mike,

Two 600 motors can move a 60lb Musashi through water .  Via kiddy car 
gearboxes they can move a tank 1 mph on concrete. On grass they can't 
turn. Not enough torque to over come the friction of the other track.
