My starscream always had its shoulder 5mm port loose (just his...left?) and I can't tighten it no matter what but among the rain makers their tolerances are different, if anything the under wing ports on ionstorm are loose on the right side but the rest are mildly better than my starscream, redwing is a tad better than all of them but only ever so slightly.
Gonna give thundercracker who just came in a good looking into because apparently his box is smothered to death, thank you amazon!
