SS Blackout is a huge helicopter (1/4 empty) that folds onto itself and form a shorty robot. I picture an evil manager at Hasbro that dictates the packaging box cannot exceed so and so dimensions.
The robot body shape also bothers me a lot. It has a huge upper body, huge hoodie over the head, and little skinny short legs. Finally I spent a day and kinda fixed it. (Like Hasbro designers, I strive for the barely good enough.) The prototype parts are in green. If there's interest, I can upload the stl files.

 

I like how the entire thing is a passive aggressive roast on Hasbro. The modifications look pretty good. Kinda more of G1 proportions now.

I actually do like the original movie design though because of how the proportions fit his size and fighting style. I think the design philosophy on his hight downgrade was to make sure there were no hollow sections in structural areas (and to keep him in scale with the autobots and such). Starscream (angry dorito bird) has a similar design style based off of his fighting technique and scaling issues.

 

Thanks for being a voice of reason. I went to the dark side with whole Ratchet exclusive and still needing many upgrades.
The parts stay in place for transform. Feet flip up. In helicopter mode, using finger, you can feel there are tons of empty space.

 

Not for me (I am weirdly amused by his head being at the same height as Starscream's), but I can't deny the results look stellar. If they ever do a Grindor repaint I may want something like this just to differentiate the two. Also, him having more normal proportions makes his lack of wrist swivel even more egregious. It kinda feeds into his original aesthetic of big hulking monster type mass of "f*** you" but when he's normalized like this, it just... argh, dammit Hasbro! xD

 

The upgrades look amazing! If this ends up being uploaded it might be enough to finally make me get him.

Is Blackout a big hulking monster? Megatron from 1/75 world seems to agree.
