90 ton 1/14 metal excavator scratch build w/embedded PC

[SteinHDan]

It's always a question where to put the required RC-components on a machine. I'm talking about things like the on/off switch, charge connector, etc. I want them accessible, but not visible.

On this machine, they could all go underneath, but I'm thinking that there might be a lot of dust, dirt, braches, leaves, etc there, and also it's not that accessible on the underside.

So on this model, I opted to put them on top, but conceal them under a lid.

I'm mimicking the engine lid from the original:





And then underneath the lid, the control panel is located. It has:
- The on/off switch
- A battery voltage meter
- A sound volume dial

The charge connectors are just a standard XT60 and a balancing connector that are accessible under the lid, not attached to the control panel.








The control panel stand also serves as the mount for the audio amplifier.

The amplifier is a 2x50w D-class amplifier. The volume control is a stereo logarithmic pot - A1k.
