I am building an rc lego car so its weight is around 1kg. I need 2 motors to have enough torque to move that weight but also be fast enough.
Currently im using two 6v dc motors as the back wheels to drive a very light arduino car with nothing but adruino uno, h-bridge and eight 1.5v batteries on them.
Can you recommend me motors that can achieve the speed the 6v motors give on the light robot car but with more torque so that it will be able to move 1kg worth of items. the speed cannot be compromised as its a major factor in my project. i need speed and power to move the rc car but i also need the motors to not take up too much space.
