ECX Ruckus 1/18 4WD

Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor. Not published means it exists but no source we could find prints it.

Gearing parts

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft (2.5 mm on the stock motor). Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

Horizon's spec table prints a 14T pinion, a 60T 0.5 module spur, a 2.47 internal gear ratio, a 10.60 final drive and a 2.95in (75mm) outer tire diameter; 60/14 x 2.47 = 10.59 agrees with the printed total.

• The motor is a Dynamite Tazer 380 brushed, which has no KV rating.
• The manual rates the 15A ESC for 6 to 7.4V and the truck ships with a 7.2V NiMH pack; no LiPo cell rating is stated, so it is left blank.
