Such a beautiful piece of machinery! A couple tips from someone who works with the full scale versions of these in a quarry (dont think i mean bad by it, just some things that could make it more fun and look nicer) For the loader; When digging up a scoop try to lift the boom very lightly whilst curling, keeps force on the front wheels and gets a bigger bucket load When your transitioning from digging to loading keep the bucket/load under your cab height to keep a low center of gravity, raise as you approach to dump keep the edge of the bucket close to the inside of the dump truck bed and lift the boom higher as you dump to keep as much as you can from spilling For the ADT (articulated dump truck) Pretty much nailed it (they are pretty straight forward, all id say is less is more, as time would teach taking movements like articulating slower looks prettier and gives you more time to think and react, and if your after realism points, ADT hydraulic pumps work on motor speed so they can really only pivot well whilst going forwards or backwards, i guess that all really comes down to a smooth fluid action Again i hope i didnt come across as offensive, just things i experience and see every day at work that makes this kind of stuff look awesome, iv only got a couple huina machines at the moment but i hope i can afford these someday, awesome stuff man!
