Hello guys, its my first post, I'd share my experiences about our new 8043:
- I bought this set because this was the cheapest way for me to get 4 motors and 4 ch RC, I look at the excavator as an extra with the motors.
- I see the structure is very (I mean very very very) weak, namely:
a.) standard turntables are inadequate for the task of carrying the upperstructure and a filled bucket
b.) LAs are very good for precisity (much better than pneus: try to climb a truck with your pneu excavator...), but they can not lift even an empty bucket effortlessly: motors are at their margins.
c.) the arm structure is wiggly it has way too much play, even if its quite oversized (bigger but worse than 8455)
d.) undercarriage has some gears outside. These gears like to jam on rough terrain (like a blanket). Covering the gears would have been more useful.
- The switching mechanism is quite good, power goes to tracks much better than I imagined. (the evident changes help: using frictionless axle connectors etc)
- motors and receivers can be removed without much pain: it makes using them in other models easy without braking dwn half the upperstructure.
- Instructions: someone above said very well: these newer (not 30 yrs old haha) ones make me feel very dumb, doesnt make me think, and my 5 yrs old cant see what she's building atm, she just goes for completion. When I was 10 I could easily modify constructions on-the-fly, nowadays I put together what I got, break it up within a few days and make a better version of it in a separate process.
- the size of this model would make a modular approach more sane (like crawlers, base, upperstructure, arm), now it is quite tricky to change some minor thingie without disassembling 3/4 of the stuff.

After about an hour of play I started to take it apart. It was clear I can make it better: now I started to build a more useful one with motors within the chains, roller bearings for the turntable and a brand new upperstructure. And maybe 5x parts count :D
Conclusion: it's a great set, maybe one size bigger than its building techique allows. Well, it motivates a proper rethink and rebuild, giving inspiration, so it fullfills its main task. Aaahhh, and it looks good! :) Even if I'm still not convinced about pure studless...
