Add a compatible_motors column as a comma-separated list (C6-5, D12-5, D12-7). A list mapping renders it as a structured block on the page, and a meta mapping includes each motor in JSON-LD additionalProperty. Builders verify motor compatibility before they buy a kit, and exposing the list structurally answers that directly.

Yes. Add columns for total_impulse, peak_thrust, burn_time, and motor_class. Map each to a structured specs block. High-power flyers calculate motor selection from impulse and burn time, not just letter class, and exposing the numbers structurally beats burying them in a manufacturer datasheet.

Add a shipping_method column with values like ground-only-with-ORM-D, hazmat-required, or no-ship-pickup-only. Map it to a callout on the page. High-power motors ship hazmat or not at all in some regions; surfacing the restriction upfront prevents the cart-abandon at the shipping calculator step.

Yes. Niche-maker pages are where SleekRank earns. Madcow, Wildman, BSD, Public Missiles, and other smaller high-power manufacturers get 50 to 200 monthly searches from cert candidates, and a per-kit page outranks any generic high-power rocketry category consistently.

Add a motor_format column with values like single-use, reload-kit, reload-only, or hardware-only. Map it to a structured badge. Buyers shopping a reload pack need to know if hardware is included or required separately, which is critical for high-power purchasing decisions.

Yes. Add a power_class column with values like low-power, mid-power, high-power. Run page groups with URL patterns like /model-rockets/estes/{slug}/ and /model-rockets/high-power/{slug}/. Filterable archives by power class give builders a clean entry point matching their certification level.

Add a build_required column with values like RTR-ready-to-fly, easy-to-build, mid-build, expert-build. Map it to a structured badge. Beginners filter to ready-to-fly; experienced builders specifically want fiberglass mid-power kits requiring building. Labeling clearly aligns expectations.

Default: keep the row with a stock_status column driving an out-of-stock or backorder badge. The page still ranks for the kit because Google indexes the URL regardless of stock. Discontinued kits get their rows removed and URLs return 404 on cache refresh.
