This is my entry into the Sail the Technic Sea contest, and Allanp is going to love all the pneumatics

The model has many remote control features, including:
1. right track
2. left track
3. blade up and down
4. blade rotate
5. blade tilt
6. compressor override
7. excavator slew

The cab was the most difficult part for me to build, and it took several nights to get the proper shape. Overall I am pleased with the shape and detail of the interior.

The model also has a ton of manual controls, including:
1. boom up and down
2. boom in/out
3. dipper extend
4. bucket curl
The excavator is slightly recycled from my previous walking excavator and it is a lot of fun to control. It is powered by a automatic compressor with the remote override, to keep the pump going even if the pressure valve turns it off.

here you can see the switches for the excavator. Originally I was going to put the switches on the body of the groomer but I ran out of room so I put them here instead.

You can also see where the battery box is hidden. Since I ran out of room in the body, the compressor and battery boxes were both placed inside the tracks on opposite sides.
Here you can see a profile shot of the whole model.

And the original(i cant re-size it because it is not my picture):

Finally a video to show all the functions in action:
