I would have loved to use my mining excavator as entry for this contest, but as it was already pretty finished it was a no-go. I therefore will try to create something new for the contest. My plan is for a tracked loader out of the parts of 2 x 42121. As my mining excavator (which needs about two copies of 42121 and another shovel) isn't digitized yet and is also needed in real for another planned photoshooting of the functions and I don't have enough copies of 42121 available - yeah I know, luxury problems - I need to disassemble my dozer and dumper 42121 alternates for the loader. I'd like to have kept the dumper at least as companion for the loader but that will have to wait until later I'm afraid. So these are the parts I have available: I think I will start with the basic functionality of the loader and setting the dimensions. It's already late now, but I couldn't make time earlier because of other stuiff. We'll see if this goes anywhere until the end of the contest but I hope for the best. Fingers crossed... -
Just checked the "volume" of my (not yet published, only shown to a friend so far) 42121 triple alternate model - a mining excavator - and it sadly is too big for TC22 with 16 x 25 x 28 (W x H x L) Well, after folding the arm and shovel completely it looks a little different and measurments change to 16W x 18H x 34L = 9792, so in the limits then. But I'm also reusing submodels of 42121 to keep the scale it would have been most likely also not accepted anyhow. So "Not TC22" just for now, I hope. But as it's a "small" construction model, I think it still fits good at the moment with TC22 starting. Functionality: lower arm can be raised and lowered with knob (12z gear) at the rear upper arm can be "raised" and "lowered" (if its movement can be called like that) with knob (12z gear) in the arm shovel can be moved from the upper arm, either with the knob (12z gear) on the left side or the 12z gear attached to the small LA The pictures are showing an older version and in my current version the upper arm can now be controlled from both the arm (now with a 20z gear) and from the rear of the superstructure (with a 12z gear). Unfortunately I haven't yet created pictures of the current version (which also features some additional details like tiltable headlights in the superstructure). Apparently this needs 3 x 42121 set inventories when using the big shovel. But I tried to build it in a way that one can also build a second model out of the remaining parts, namely my two already existing 42121 alternate models: Tracked Dump Truck Futuristic Dozer But as I haven't yet digitized the mining excavator, I'm not yet sure if the dozer can really be built in addition, at least there are enough LAs left for it. The dump truck is definitely possible, though. My aim with these alternate models is to provide construction equipment that matches the scale of the original 42121 A model. Therefore I am reusing some assemblies (though sometimes changed depending on parts usage), mainly the cabin and in this model and the dump truck also the base and tracks. Here are a few pictures of the previous version of the mining excavator (and later also together with the dump truck):

I converted the 42121 Heavy Duty Excavator to a RC version that can be driven and moved. * Instructions are being distributed by Recrickable. https://rebrickable.com/mocs/MOC-69683/Seo-onDaddy/42121-heavy-duty-excavator-full-rc-mod/#details * A 4-port receiver such as 'MOULDKING' receiver or, 'CaDA' receiver or 'Buwizz' is required, and case separation is required.'MOULDKING' receivers do not require any work other than case separation.The 'CaDA' receiver or 'Buwizz' must be removed from the case and the battery must be replaced in a small size.Battery size should be less than 14mm x 25mm x 50mm. * I modified some parts of the exterior because the space was cramped. * fixed the range of operation of the arm operation. -
A surprisingly good set here. I'm really impressed by how LEGO managed to make such a relatively small set look so realistic.
