There's still more to do, it will have a full luffing jib boom and Maxer wheeled counterweight.
About this creation
This model is semi scale, 2 studs = 1 foot. All functions are powered, everything above the crawler base is controlled with the power functions IR receivers. Eventually it will have a full luffing jib boom, engines, operator's cab and some other smaller details. Then a hole in the ceiling so I can put it all together...
