No Nomad.

Yeah - longer wires will add resistance, and be more noticeable with motors or anything drawing high current. However, how long are the wires? Because adding a few inches won't make a difference. You'd have to add a wire two or three times the length.

For example, using servo extension cables will reduce battery life because servos use quite a bit of energy.

Also, a thinner wire will be much higher resistance.

It must be a very long wire Dj, and i dont belive that Nomad´s robot has 20 meters of wire.

i use 3 extention cables each servo.
