This is how I went about Building a Scale Trail Truck using parts of other R/C cars and trucks. Many of these parts come from the ECX 1/18 Temper which is the same as the Redcat Racing Everest 16. From these trucks I built something very similar to the ECX Barrage, HSP and the RGT line of trucks (Like the Rock Crusier). So if you're interested in building your own 1/10 or 1/12 Rock Crawler or Scale Trail Truck, read on.
