W-MM configured chassis equipped with a high-performance 8500KV motor, EVO chassis set is the perfect step up from the Readyset. First released in December 2018 the MR-03EVO series delivered amazingly fast processing speed and featured a separate receiver board that provided the flexibility of transmitter choice. Two years after its stunning debut, the MR-03 EVO lineup has been strengthened with a race-based chassis. A 8500KV motor is combined with a standard specification chassis that you can customize to your liking with various optional parts available. While retaining the full bearing specifications and Ball Diff Set II, align the base chassis with the new standard speed range and open a wider group of users.
