"It was cool to see this offering for 2018, a big fan of technic trucks. I also have the Acros Truck too and it would be good to compare the two The build was straight forward but it took some time. The most intense part was building the cab, there were a lot of small parts for it construction. Comparing it against the Acros, there are two main differences, one is the control of the vehicle. The Mack control system is more stable than the Acros, where the Acros system gives you the feel it was going to break based on the tension being applied. the accessibility to the engine is relativity the same as the Acros.
I was initially disappointed with the engine in the Mack, using standard pieces to build the cylinders rather than the engine mimics as in other products. But after building it I was quite happy with the turnout, gives you a nice clicking sound and is the right size.
I find the hitch to be strong in the Mack, the Acros kept falling off during the drive. What I do not understand is the insertion of the bed in the cab with no easy access to use it. The mechanisms for the cargo hold is nice, I think it was best not to include the motors, the movement is overall very strong and stable through the whole process. While I like the pumps and motors, the can complicate the design For playing, I find the engine hood to be sensitive with part easily falling off.
