[TC26] 6x6 Arctic Crane Truck

[TechnicRCRacer]

If time permits, I plan to enter this new contest, it seems exciting! I have settled on a 6 wheel drive crane truck with rugged tires and several pneumatic functions. Currently I have the drivetrain working with a pneumatically locked central differential. Once I work out the front end, I will add the compressor and start on the crane.

My plan is to have an XL motor for drive, a servo for steering, an L motor for the compressor, and another servo to operate the valve for the diff lock.

Looks like a good start!

I've made some more progress on the model, mainly the area hosting the compressor and differential lock valve. Since this model will be packed with functions, I decided to forgo the interior of the cabin and place the two function motors and compressor inside. I also did some work on the front of the model; the red and dark green parts are placeholders.

Here's a view of the underside:

I don't have the remaining two wheels yet 

 

The next steps are building out the cab bodywork and roof, routing the pneumatic hoses, and building the base of the pneumatic crane arm. I imagine routing the hoses and finding places for the manual valves will be the toughest part of the model.
