RC4WD Trail Finder 2 LWB RTR 1987 Toyota XtraCab

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. Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how. 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.

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.

How these numbers were settled

RC4WD's specification for this truck, as carried by RPP Hobby, prints the whole drivetrain: a 14T pinion on a 64T spur (4.57:1), the R3 single-speed transmission at 1.78:1, the Hammer transfer case at 1.47:1 and 15/40 axle gears at 2.67:1, for a printed final drive of 31.9:1.

• The ratio after the spur is the product of the three printed stages, 1.78 x 1.47 x 2.67 = 6.99, and 64/14 x 6.99 = 31.94 matches the printed total.
• The motor is RC4WD's 45T brushed 540 crawler can, so there is no KV.
• This listing prints the total as 31.93:1.
• The tires are Goodyear Wrangler All-Terrain Adventure 1.55; RC4WD's tire copy reproduced by RPP Hobby gives 'Outer Diameter: 3.74in / 95.0mm', so the diameter shows as estimated.
• The Outcry III ESC is rated '2-3S LiPo or 5-9 NiMH' in RC4WD's own ESC sheet; the truck ships with a 6-cell NiMH pack.
