RC4WD Trail Finder 2 RTR Mojave II Midnight Edition

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.

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.
• RC4WD's own manual for Z-RTR0054 confirms the 45T motor and the Outcry III ESC at '2-3S LiPo or 5-9 NiMH'.
• The tires are Interco Narrow TSL SS 1.55 scale tires (Z-T0182 in the replacement parts list); RC4WD's tire copy reproduced by RPP Hobby gives 'Outer Diameter: 3.74in / 95.0mm', so the diameter shows as estimated.
