Propane Flamethrower

This is a large flamethrower designed to be used with a separate backpack. The backpack holds the fuel and batteries for the flamethrower. It uses propane as the main fuel source. It also uses a small propane torch as the pilot lighter. A push button opens a solenoid valve which allows fuel to flow out of the backpack through a tube and then out the nozzle. The entire flamethrower is made of metal.
