About RC Changelog

A bashing truck gets a new letter or number tacked onto its name every year or two, the manufacturer's product page quietly swaps in a fresh set of numbers, and nowhere does it say what actually moved between the old version and the new one. Owners end up piecing it together from forum memory and side-by-side guesswork. RC Changelog exists to replace that guesswork with an actual diff.

For every generation pair listed here, both sides come from the manufacturer's own spec sheet and exploded-view parts diagram, run through a normalizer first so formatting quirks don't get counted as real changes — 4.3 one year and 4.30:1 the next is still the same ratio. What comes out the other side is a side-by-side table: values that genuinely moved, fields that only show up on one generation's page (which is not by itself proof a feature was added or dropped), and exploded-view part IDs sorted into new, no-longer-shown, or carried over unchanged.

How the sourcing and normalizing actually works is written up on the method page.

Nobody at Horizon Hobby, ARRMA, Losi or Axial runs or endorses this site, and it's independent of all four — nothing on it is sold or sponsored. Every part ID that has a manufacturer product page links back to it purely for reference, with no affiliate tag or tracking parameter riding along. Found something wrong?
