This is a rebuild/upgrade of my first tow truck. Features are as follows:
- 8x4, powered by 2 L motors geared down 3:1
- proportional steering on 2 front axles using servo
- pendular suspension on rear axles; independent suspension on front axles
- side and rear outriggers
- tow fork
- tilting cabin
- fully functional, 360° rotating crane
- fake engine (straight 4)
The cab is a mod of the Arocs; the side outriggers are pretty much the same as 42070's. All the functions are driven by an L motor and 9 2-way selector switches (6 on the truck and 3 on the crane).
Here are some quick pics - will take better ones and shoot a video when decent lighting is available.
It's pretty heavy, so I had to use eight hard shock absorbers on the front wheels. In spite of the weight and the ridiculous amount of friction due to the old wheel hubs (8297), the servo still works smoothly.
