I bet if I were to unearth my Energon Storm Jet and Armada Sideways, I can almost guarantee that I wouldn't remember the transformations. Maybe not so much on Sideways.
Universe Silverbolt. I keep forgetting to stand the jet on it's end and say, Transformation complete.
Occasionally. Figures like Leader ROTF Prime and ROTF Mixmaster always confuse the heck out of me, but they're still fun to try and transform!
On Alt Sunstreaker, I occasionally have a hard time remembering the arm placement to go under the back end. But I usually just fiddle around with them until I get it right. However, this morning, my 4-year-old wanted The Burning Fallen into jet mode & I had to stare at it for a moment to remember what it looked like to get it there. I have the 1st release & didn't change it very often since he never seemed to transform in the movie. Other than that, I don't seem to have any problems with getting things where they need to go.
I forget all the time because I don't mess with mine. They stay in a case and I just look at them in passing.
Sadly my memory's stuffed with transformation steps, music and other stuff. The drawback is I can't seem to learn new, actually useful things.
I haven't forgotten a transformation before. Strangely enough however, I've forgotten how Revoltech Gurren Lagann's articulation works.
every time i forget a transformation,i simply go to youtube and look up a "review" video how to transform it! problem solved! but i dont seem to forget, except for rotf leader prime back to truck mode. talk about a REAL pain in the Ass!
deluxe or human alliance? i had him as a deluxe once, and it was almost impossibly to keep his "backpack" up
I've never completely forgotten the transformation scheme of a figure, but I sometimed will forget small details.
