I believe I saw this MOD on another of peteria's MOCs. I changed the current turntable design to incorporate a 2nd gear rack circle and use 1x1 round plates as bearings. As a result the gear engages more consistently and rotation is much smoother.

Tried to keep the color consistent and infilled more gaps than in the original. Without superstructure and boom the steering and drive work very well.

Without superstructure and boom the outriggers easily lift the undercarriage without straining the motors or causing sag.

Outriggers work very well and are very robust.

Some added detailing. 2nd battery box will power the superstructure.

Completed undercarriage with my own MODS for robustness and aesthetics. Total length is 101cm!
