What the table does not tell you
Noise and lights. The four rechargeable 1:24 models have engine sounds, working lights and an auto-demo mode. 1:64 is silent. The Specifications table on each product page lists the exact features.
Durability. All three scales are made to be played with, not just displayed — but none of them likes a fall from a table, fine sand in the gears or water. Our Spare Parts page has the care tips that keep them running.
Batteries. A 1:35 excavator eats AAs. If the model will be used every day, a rechargeable 1:24 is cheaper over a year.
Display. At 1:64 you can line up the whole fleet on a shelf. At 1:24 a single model needs the space of a shoebox.
Our pick
For a first Cat RC, the 1:24 336 excavator or 745 articulated truck: the rechargeable pack means it is ready to play the moment the box is open, and the two work together on the same site — dig with one, haul with the other.
