Excavator electronics help
 

Hi all,
I am going to be making an excavator soon and I need to know some electronics that I will need. I am also wondering if any programming is needed and if I need resistors and other components in my circuit. It's going to be a John Deere road builder excavator. Thanks!

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..)

Thanks for the help! I plan to make the machine soon. Is the rectangle with 2 circles on it the battery?

Re: Excavator electronics help
 

No that would be the hydraulic tank.

Re: Excavator electronics help
 

On a second thought, that makes more sense. Now on the hydraulics, is there an auxiliary relief valve in the valve block?

Re: Excavator electronics help
 

It's external, between the valve & the tank.

How do I put wires through the turnable without them twisting?
