Hello!
I have built an 8x8 version of the Arocs. The cabin and the rear suspension remained the same as the original. The crane arm is removed and the dump body was extended. Remote controlled pneumatic functions were added. Front axles were rebuilt, differentials were integrated, the steering linkage principle remained the same, but operated by pneumatic cylinders. The middle chassis part was totally rebuilt to integrate the motors.
Motorized functions:
-Driving (by XL motor)
-Steering (by two pneumatic cylinders, valve controlled by M motor)
-Switchable all wheel drive vs only rear wheels drive (by M motor)
-Dumping (by two large pneumatic cylinders, valve controlled by M motor)
-Pneumatic pumps (3 pieces of 6L pumps, driven by L motor)
Other functions:
-Tiltable cabin
-Automatic compressor turning off
-Suspension system
