Speedy's GF01 Heavy Dump Truck Build Thread - The Builds
Mar 29, 2016 · Tamiya markets this model as a 1/24 kit, so full scale speed is about 21 feet/second, 14.3 mph, or 23 km/hour. If we're comparing the model to a full-size Caterpillar 797F, on the other hand, the scale is more like 1/41. In that case the scale speed is 36 feet/second, 24.5 mph, or 39 km/hour.
