This document is an assembly guide and parts list for two Monster Truck models, the 555-44400 Torch and the 555-44500 Hooligan, manufactured by JEGS. It provides detailed instructions for assembling the remote-controlled (R/C) monster trucks, along with important precautions, required tools, and a comprehensive spare parts list.
Function Description:
The JEGS Monster Trucks are remote-controlled vehicles designed for off-road use, capable of high speeds (some models exceeding 25 mph). The assembly guide covers the construction of various components, including shocks, front and rear end assemblies, center differential, radio tray, battery tray, chassis, wheels, tires, and an optional wheelie bar. The trucks feature waterproof electronics, allowing for use in various conditions, though prolonged submersion is not recommended. They are controlled via a radio frequency transmitter, emphasizing the importance of proper setup and avoiding interference.
