I have seen plenty of FPV videos of homebuilt racing drones with wires across the front for fusing some explosive charge. I have seen another drone watch a small racing drone hit an APC with people riding on it and explode with what is probably a few ounces to a pound of C4. I have seen FPV drones supposedly carrying RPG rounds to attack lightly armored vehicles.

I have seen zero videos of racing drones not even a foot long and foot wide carrying 30 pound artillery shells. I have seen zero footage of those tiny racing drones in the air under their own power carrying a 30 pound artillery shell. I have seen zero evidence of it even being possible for a notebook sized racing drone to carry 30 pounds.
