Default Bullet Connectors

Some RTR's feature bullet connectors on the motor cables, while race rigs solder the motor wires directly to the ESC.

Simple question; why?

Resistance and reliability. However slight, adding the resistance of the connector itself and moreso, the resistance of a second solder joint to that line of wiring is something racers don't want. Racers also don't want a potential failure point in that wiring.

Also, most RTR's have connectors on the motors because most companies assume most RTR owners are going to want to change that motor at some point and said RTR owner won't be able to solder in a new motor.

In a bashing rig, even on an SCT, I can see where motor wires pulling apart is a big deal. To that end, constantly disconnecting the cable is the likely culprit.

As a racer, I have a car that is able to have the various electronic components in different places, but soldering motor wires over and over again presents it's own problems. I think connecting the wires and then applying heat shrink over them would go a long way towards mitigating possible separation.

Weight is another consideration, connectors are heavy when compared to the rest of a 1/10 or 1/12 scale car.
