While your arm design does seem fairly accurate, the way they connectors are attached that allow for the shadow trap as shoulder armour seem like they are a bit problem filled;
Problems that occur from this design include the rod piece not connecting fully, the rib piece being bent outwards and not connecting properly to the balljoint, general flimsiness with the connection and potentially bending pieces to ensure they are lined up.
I’ve built a rough version of the arm to test if these issues can be fixed with the current design the way it is, and it is not possible in my view. As such, I’m going to vary slightly from the official design when it comes to doing the upper arms on my version, as i feel the proper design for the upper arm has a high potential to cause issues.
True, sadly i feel you may have been 100% accurate and that the official version is full of these sorts of things. It was likely something in its very early stages either as a prototype for a potential 2017 summer set or simply as a design to encourage the Makuta building contest. I’m just concerned that the design may be made in a way that is not sustainable due to illegal connections that could cause damage to pieces.
You could always remove one of the small thin technic beams and push the shadow trap forward. It may be a little more loose but it could fix you’re problem.
Managed to get quite a bit of progress done, very doubtful that its built the same way in the official version, but i like how its coming along so far. Lots of pieces are temporary and need to be replaced with correct size/colour pieces later.
I tried several attempts with the gearbox - however due to the design of the arm connection even if he happened to have a gearbox it wouldn’t be able to move properly as the pieces clash against his chest. Its possible to avoid that by making the model have more ‘depth’ or by extending out the arms however both options just ended up looking weird.
What country are you in? If you live in Europe, you shouldn’t pay much more for postage if you buy from another country within the EU. I live in the UK, and if I ever buy from, say, France, it’s only ~£1 more on postage and a couple of days longer to wait for the items to arrive.
Hello I am RAKRONDEWL, I see you guys are trying to build the Overlord Makuta, I am also working on the model in LDD but I am unsure how to share it with you guys. I’ll try to figure it out because, I think I may have figured out a little more than whats been posted here.
