Bought this set as a companion set to the Tracked Loader.
Spent time over several days building this set, or rather teh A model as not yet done the B model. And not having done any sets with pneumatics before, found the build an enjoyable challange.Found the pneumatics don't always work first time, yet that is as much to user as anthing while getting used to them. This set is a good introduction to the whole world of the pnematics.
There are some nice details on this set that help make this set a nice set to look at and use. The only real downside is balance. In using the arm part when the cab is rotated to either side, the completed model starts to tip to that side. That said it is a fun set and enjoyed building it. Looking forward to buiding the B model.
Would be interested in a next generation version that address the balance issue :-)
