Cat 340D Excavator build

[crueby]

Got enough of the wiring done to test things out, and swapped the main boom motor for a slower/stronger one which is pretty close but could be a little faster. Here is a short video testing the different functions out, moving slow so I didn't whack anything on the table and so I could learn which stick did what!

Another major assembly almost done - got the track frames/tracks assembled this afternoon, moving quite well. Still some more trim panels and brackets to go on, and need to pull the tracks off one more time to install the drive chains and sprockets on the inside. The chain sprocket on the center of the track drive sprocket is there, but there is another one in the center of the frame that still needs to be fitted. The drive motors will sit on the inside edge of the track frames, under the middle of the cab (one per track). As mentioned early on in the build, these are NOT true scale tracks for this machine, but are re-purposed from a RC Tiger tank model - getting me running a lot sooner, to see how the whole thing functions. They can be replaced later with better scale tracks if I get the time for it.

More done on the tracks - got the frames painted, chain drives installed, and fit to the frame. Here is a test assembly of the whole thing, will pull the cab/booms off again to turn the track assembly upside down to fit the motors to the bottom. It definitely is more stable now with the extra width and length to the footprint.

Got the motors mounted to the track undercarriage, ready to wire things in...
