Most crane/draglines don't have independent swing and travel so you wouldn't be losing anything as far as realism goes. On the other hand, it would drive me nuts to have to run a 1:1 excavator without being able to travel and use all the other functions at the same time.
How are you planning to drive the tracks? My idea was to bury servos inside the carbody under the swing circle with sprockets on them sticking out either side and running chains back to the drive tumblers. |
When I get more parts in I'll decide on the drive source. I am thinking either small 200:1 (or more) all metal geared motors or a metal geared servo for each track.
