Fire, Water, Steam, Motion. A fun build of a r/c live steam powered tank with turret & gun.
I've always enjoyed live steam powered machines, but Crabfu's steamtoys inspired my imagination.
This is my spin, with dual engines for independent track control, a working turret, and simulated cannon fire action. The tank uses 100% live steam power for propulsion. Batteries only power the radio/controllers, lights and effects. It's based on an old Tamiya 1/16th scale King Tiger off eBay.
Yes, this uses flammable gas (camping fuel), fire and water to produce pressurized hot steam. The boiler gets hot, the pipes get hot, the engines get hot, the exhaust pipes get hot. You'll need to use a torch to solder brass & copper pipes. Burns & blisters happen easily if you're not careful. Whatever you do never modify or block the boiler safety valve. Always wear safety goggles & keep a fire extinguisher handy.
There is a lot to do. Let's get started!
