RC4WD Trail Finder 2 RTR Chevrolet Blazer

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 the Rust Bucket Edition, 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.
• The axles are K44 cast axles at 2.67:1.
• The tires are Mickey Thompson 1.9 Baja Claw 4.19 scale tires, listed at an outer diameter of 105.8mm; the 4.19in in the tire's name works out to 106.4mm, a difference of under 1mm.
• 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.
