That's pretty good! The only Alternator to stump me now is the Skids mold but only because I couldn't make sense of how to store the arms to make everything fit. It was one of those things where I probably could've gotten it over time but I just got frustrated because I was just trying to get my Binaltech Blaster into my display cabinet  .

Wheeljack/Grimlock never really gave me issues as I added those figures to my collection though. I kind of wish Has/Tak would've done a better job with them because I'm a pretty big fan of both characters and I absolutely hate that huge flap hanging off their butts.

 

Oh man that's like the only movie toy I get excited to own more than one version of. I thought Sentinel had a slightly easier transformation but man I really struggled over the weekend when I was fiddling with mine. You get pretty comfortable transforming something like the ROTF Optimus mold when you own 5 different versions but I just didn't realize how much I would forget about Sentinel after not handling him for a little over a year    

 

Oh but to answer the original question in this thread:

You know you've made it when you can transform FP Diesel without instructions. That thing kicks my ass every time.

 

I never bother with transforming the Alternators now. Skids, Dead End and Tracks were maybe the only ones I could do.
