30 Minutes Missions invites you to build a model and then change its silhouette, equipment, or configuration. The easiest first purchase is a complete model you already like. Option sets make more sense once you know which base kit they will work with and what you want to change.
Choose one complete kit, build its standard configuration, and add one verified customization afterward. That approach keeps your first shopping list understandable and gives you a reference for how the original assembly should fit.

A base kit and an option set are different purchases
Check the product name, contents list, and instructions. A complete robot kit, a weapon set, an armor set, and an accessory or vehicle kit can appear together in a catalog without providing the same starting experience.
Promotional photographs may show multiple separately sold products combined. Find out which items are actually included in the box you are considering. A dramatic customized model in an image is not evidence that every component shown comes in that purchase.
For a first build, write a one-line inventory: “This box builds the model I want; these accessories are included; these displayed additions are separate.” If you cannot complete that sentence from the listing and official information, clarify it before buying.
Choose the silhouette first
Look at the standard assembled model from the front and side. Consider whether you prefer a compact shape, long limbs, heavy armor, or a more specialized configuration. Picking a base design you enjoy makes the initial build worthwhile even if you never buy an expansion.
Also consider where you will display it. A wide accessory arrangement needs a different footprint from a compact standing pose. Planning a shelf location now helps you choose additions that fit your space rather than discovering later that the finished build cannot turn without striking its neighbor.
A concrete example: Gardonova
Artrovo Gundam lists the 1/144 30MM bEXM-29 Gardonova in green. Check that page for current availability and purchase options.
Bandai’s official product page describes its long articulated arms, reconfigurable large claws, and included submachine gun. It also identifies a combination with the separately sold Revernova. That named example is more useful than assuming every part from every related range fits every other model.
The official Gardonova manual page provides a reference for the specific release. Compare the manual and product contents before planning a purchase around a photographed combination.
Check compatibility at the connection
A shared-looking peg is only the beginning of a fit check. Ask what the part attaches to, whether an adapter is required, whether that adapter is included, and whether the surrounding armor leaves enough clearance.
Exact products: identify the base kit and option set by full name.
Connection: compare the intended mounting point and connector.
Required parts: confirm any hands, adapters, or extra assemblies needed.
Clearance: consider nearby armor and the range of movement.
Balance: consider the added weight and leverage of the finished arrangement.
Do not treat a nominal connector size as a guarantee that all 30MM, 30MS, 30MF, or other model parts interchange. Product-specific instructions and demonstrated combinations are the stronger starting point. A connection that requires force is a reason to stop, not proof it is almost compatible.
Build the standard model before mixing parts
Keep the runners, manual, and unused pieces organized during assembly. Photograph the completed standard configuration, especially connections you intend to change. It provides a useful reference if a later customization introduces a loose fit or restricted movement.
For the first modification, change one section or accessory. Check the result gently through its intended movement before adding more. This makes it much easier to locate the cause if two new parts interfere with each other.
Store the original components in a labeled bag or compartment. Reversible experimentation is one of the pleasures of modular building; it works best when the parts needed to return to the original configuration are still easy to find.
Give yourself the time you need
The range name is not a deadline for your build. Cutting, cleanup, instruction reading, and optional detailing all affect the session. A careful first assembly can take longer than a quick promotional demonstration, and that is not a problem.
A suitable plastic-model nipper and a simple cleanup setup are enough to start investigating the kit. See the first-build toolkit for the general tools, and follow the specific model’s instructions.
Keep the first order focused
Start with the base kit, the tools you are missing, and at most one option whose fit you have verified. Browse Artrovo Gundam’s mecha catalog for current choices. Stock and purchase eligibility are shown by the live listings; a catalog entry alone does not mean an item is on hand.
If an option set’s contents are unclear, send the exact two product names through contact. Resolving that specific question before ordering is easier than designing an entire build around an assumed connection.
