Excavator electronics help

[Rimrock]

The wiring diagram above is a good standard for a RC excavator. Some setup/programming is usually needed concerning the radio and ESC 's(electronic speed controller), it will be explained in the manuals. It happens in some rare cases that resistors are needed to be added concerning hook-up of some certain lights in a model. But usually no need to think about small electronic components, the ESC and other electronic units comes ready from the factories, just in many cases need to attach some connector plugs on ESC's, motors by soldering.
There are mainly two types of ESC; for standard brushed motors, and for brushless motors. Brushed motors is the most commonly used in construction models. With ESC's, and other electronic units, one must watch out for never mix the 'pluss' and 'minus' cables when hooking up to the battery..then it usually is 'came over' for the unit..)
