There is a video claiming Russia is testing these drones

The Russian Army is currently testing Ukraine's "Dragon's Breath" FPV drones, which are designed to deploy thermite incendiary munitions. These munitions can reach temperatures exceeding 2,400 degrees Celsius and typically consist of iron oxide and aluminum powders. Known for their extreme heat capabilities, these drones are used by Ukrainian forces to inflict severe damage on Russian equipment. The testing of these drones by Russia highlights the evolving tactics in the Ukraine conflict, with both sides increasingly relying on advanced drone warfare. The use of thermite munitions introduces a new dimension to the military operations.

So it's powder not liquid fuel which would be lighter

Military specialists will recognize the type of munition. There is no explosion, and no dense white smoke as there is from phosphorus incendiaries. The other tell-tale sign is that it burns hot enough to go through metal. This is thermite.

Usually made of a mixture of powdered iron oxide (rust) and aluminum, burning thermite is a popular high school science demonstration. It burns because the oxygen in the rust is more attracted to aluminum than iron, so it does not need external oxygen and will burn underwater.
