The Searchlight mold is my favorite PCC I own, though I suspect there's some bias there.
In any case, it's quite a good mold. The rotors are just on 5mm pegs and come out fairly easily. My Searchlight's are tight but will slide out easily enough, while my Windburn's are REALLY tight, but they do come out, just takes getting your nail under the lip of the black part with the peg, so mileage may vary, but they do come out easily enough. The mold's fists are rather deep, so I display Windburn with both of the rotors in one hand as a big rotary blade weapon.
And yes, there's no locking mechanism for the side sections that the arms and Power Core pegs are on, but both of mine are tight and it's designed well; you won't have any issues with the parts rotating freely away from where they're supposed to sit.
I'm really fond of his jointings, his legs are great, and he can pull off a "powered armor" sort of look quite well since his arms are completely free in torso mod.
