Overview
I really like the Lego 42042 Crane. It covers all the basic features you want, and lets you switch the functions manually. That said, I do like making things remote control. When I found these instructions, and the difference was something along the lines of $20 in parts (not counting the motors/sbricks which are used for many things), I knew I had to do it.
Features of the MOC
- Make use of the majority of the parts from the 42042 set
- 6 independant Power Functions
- Independant Left and Right tracks
- Pivot
- Boom raise/lower
- Claw raise/lower
- Cabin raise/lower
Additional features I added
- Lights on top of the cabin
- Pendular suspension for the wheels on each track
- This was accomplished pretty trivially. I pulled the 2x 11 stud beams and 1x 7 stud beam out of the bottom of each track assembly and substituted 2x 7 stud beams (1 on each end) and 1x 3 stud beam in the center. The bogey wheels maintain the same positioning
