ARRMA RC trucks: what changed from one version to the next

RTR bashing trucks get a new generation every year or two, and the manufacturer's own site rarely says what actually changed. We re-parse the manufacturer's published spec sheets and exploded-view parts lists for each generation and line the numbers up side by side, so you can see exactly which values moved, which ones just changed how they were written, and which part IDs were added or dropped.

How this is built

Each spec value on the comparison pages links back to the manufacturer page it was pulled from and carries the date that page was checked — the method page spells out the whole process. Reformatting doesn't count as a change on this site: 4.3 on one generation and 4.30:1 on the next are the same ratio in different notation, and the diff logic here is built to tell that apart from a spec that actually moved.
