Compare Loc Precision's Decal Set 390 V2 and AMRAAM AIM-120C 4" decal sets on vinyl type, conformability, and scale accuracy to choose the right markings for your rocket.
Quick answer
Choose Decal Set 390 V2 if you need premium cast vinyl that conforms to curved, compound surfaces and want the most forgiving application. Choose the AMRAAM AIM-120C 4" decal set if you are building a 4-inch AMRAAM scale model and want accurate, budget-friendly markings.
Vinyl type and conformability
The biggest practical difference is the vinyl itself. Decal Set 390 V2 uses premium cast vinyl, which is thinner and more flexible than calendared vinyl. That makes it easier to wrap around nose cones, fin roots, and other curved areas without lifting or creasing. The AMRAAM AIM-120C 4" set does not list a vinyl type in the catalog, so treat it as a standard marking decal: fine for mostly flat body tube sections, but less forgiving on tight curves. If your build has complex curves, the cast vinyl of the 390 V2 is the safer choice.
Scale accuracy and subject
The AMRAAM AIM-120C 4" set is purpose-made for a 4-inch diameter AMRAAM AIM-120C scale model. If that is your build, the markings are already sized and laid out for the model, which saves you from resizing generic decals. The 390 V2 set is not tied to a specific rocket in the catalog, so it works best as a general-purpose marking set for sport models or scratch builds where exact scale markings are not required. In short: pick the AMRAAM set for a true scale AMRAAM, and the 390 V2 for flexibility across different builds.
Application and durability
Both sets use ECOSOL inks, which are environmentally safer and produce vivid graphics. The 390 V2's cast vinyl is more conformable, so it can handle rivets, panel lines, and curved transitions with less risk of bubbles or edge lift. The AMRAAM set's vinyl type is not specified, so if you plan to apply it over complex curves, test a small piece first or use a decal setting solution. For flat body tube markings, either set applies easily.
Trade-offs at a glance
- Conformability: Decal Set 390 V2 wins: cast vinyl stretches and curves around complex shapes. The AMRAAM set uses an unspecified vinyl, likely less forgiving on tight curves. If your rocket has many curved surfaces, lean toward 390 V2.
- Scale accuracy: AMRAAM AIM-120C 4" wins for a 4-inch AMRAAM build: markings are pre-sized for that model. The 390 V2 is generic and may need trimming or resizing for scale projects. Building a scale AMRAAM? The AMRAAM set saves time.
- Value and flexibility: The AMRAAM set is lower priced and purpose-built; the 390 V2 costs more but works across multiple sport models. Choose based on whether you want a one-off scale set or a versatile marking set. Buy for the build you are doing now, not for a future maybe.
