The cgi people made a mistake and did not make the arms the same length! 

,....funny, when I first looked at the picture on the kamera display I thought the same thing

it's striking what perspective and a kamera lens can do, they are only about 15cm apart, but they are of course of the same lenght.
Made some different Decals for the thinner arms,....Looks much better this way !
Nice! Amazing detail. What do the decals say? Are they lap characters?
At this point, HPO, can you reflect on the supposed model hoax theory? I mean now that you have a good handle on how much work actually goes into building only one of these from scratch (even without all the work to design these things).
Makes me scratch my head when I consider from just the object standpoint alone how much work goes into something like this and for what? To give the internet something to laugh off?
Yes they are all Lap characters, and all readable

, about the model hoax theory,... when I look at the sharp edges on some of the details on the drone on the photo, when it was a model, it must have been a lot bigger then my drone model of 70cm.
Our machine can produce amazing details, but when sanded and painted, edges lose their sharpness and small details are getting blurry,
even when I use an Airbrush for painting.
But when it was a big model you get other problems, like bending of the arms under their own weight, and of course the costs involved when using strong and stiff enough material.
And like you said, why would someone make such a big model and never take the credits for it?
When it is a hoax, I still would go for a CGI hoax, but again, why ??, for a coming movie ??, for a laugh ??
And yes it's easier to recreate something then actually design from scratch, but of course not impossible, as a Rapid Prototyper I see new designs every day from car manufacturers or architects or new electronic products, and some of them are very complicated designs.
