About RC Changelog

RC bashing trucks get refreshed every year or two — a new letter or number gets tacked onto the name, and the manufacturer's product page quietly swaps in new numbers with no changelog. Forum threads fill the gap with guesses and half-remembered comparisons. This site exists to answer "what actually changed" with a diff, not a guess.

For each generation pair we cover, we take the manufacturer's own published spec sheet and exploded-view parts diagram for both generations, normalize the formatting differences (a ratio written 4.3 one year and 4.30:1 the next is the same number, not a change), and show a side-by-side diff: which values actually moved, which fields only one generation's page lists (that alone doesn't mean a feature was added or removed), and which exploded-view part IDs are new, no longer on the diagram, or shared between the two.

Full sourcing and normalization rules are on the method page.

This is an independent, unofficial reference project. It is not affiliated with, endorsed by, or operated on behalf of Horizon Hobby, ARRMA, Losi or Axial, and it doesn't sell anything. Part IDs link to the manufacturer's own product page for reference only, with no affiliate or tracking parameters. Questions or corrections: hello@rcchangelog.com.
