Not withstanding the fact that combining a drone and a flamethrower is a bad idea, Throwflame (the company behind the commercially available flamethrower we saw a few years ago) wants to sell you one anyways. Throwflame is not selling the entire drone, though; the company is selling you a kit that will turn your otherwise mundane drone into a fire-breathing flying menace. Obviously, not every country and state allows this, so you ought to check with your local authorities before proceeding.
Also quite obviously, it is NOT for all types of drone. Your drone had to have at least 5 lbs (2.2 kilograms) of payload capacity to haul the 4 lbs (1.8 kilograms) contraption. And if it does, then good news because, once equipped, your lovely drone will be bestowed with a carbon fiber body flamethrower with a plasma arc ignition system and a gallon (3.8 liters) fuel capacity that affords 100 seconds of spewing fire up to 25 feet (7.62 meters). Something tells me this could be super fun and at the same time super dangerous.
A flying flamethrower isn’t as sinister as it sounds. It can be a useful tool, like for clearing agriculture land or getting rid of trash on power lines. But TBH, if I want a fire-spewing flying contraption for ‘fun’, I’d rather go for something more apt like, you know, a RC Fire-breathing Dragon, for example. Just saying… In any case you are enamored by the prospect of a fire-spewing like, for example, a DJI M600, then you can pick up the TF-19 Wasp Flamethrower Drone Attachment for $1,499.
