Wiring for DIY excavator setup
 

Hi guys I have a custom excavator project I’m working on. I have a t8FB controller and receiver along with an esc. My throttle will be controlling the brushless motor for the hydraulic pump. I have the 3 valves to control hydraulics on boom then 2 small low amperage DC motors that will control forward and backwards on the tracks, which will have high torque gearing to help keep motor load low. And the last motor will be controlling the spinning rotation of the body. I’m curious what channels I should be wiring each of these controls too. This is my first project with 7 channels

a few channels short in iho..10 ch min.

• Left hand left = Swing left.
• Left hand right = Swing right.
• Left hand forward = Stick Boom (Dipper) away.
• Left hand back = Stick Boom (Dipper) close.
• Right hand left = Bucket curl in (closed)
• Right hand right = Bucket curl out (dump)
• Right hand forward = Main Boom down.
• Right hand back = Main Boom up.

The left right is one channel running on dc motor
the boom/ bucket movements are run off servos on channels that will open bi directional valves

Put the hydraulic pump on a toggle channel. Why would you waste a throttle control for the pump. :confused:

pump will need to be increased and decreased. set psi will work? I dont think so

How often do you need to adjust the pump rpm?

yes so I did settle on just setting the pump to a high low toggle. But I still am trying to figure things out for arm movement and driving. I will be using four channels just control arms. Then I have a differential controller for the two DC motors on the tracks. The best solution I can think is two controllers. One for driving and one for arm control. But I know that’s overkill and probably a better solution

If you're considering buying second radio, it might just be better to pick up a computerized radio like a Radiomaster TX12 or Jumper T-Lite. This will enable you to set up toggles to set whether your sticks are controlling movement of the tracks or hydraulics at the flick of a switch. A setup like this will give you much more flexibility than your current radio.
