It's both. DJI drones while expensive they are rather user friendly. Some fighters in Ukraine do use them with aftermarket droppers[1]. Payload is limited to a single VOG-17M grenade. Dropper has a light sensor and is triggered by aux light. They also build custom drones as well. For example there's R18 by Aerorozvidka[2]. Which is largeish octacopter from higher quality hobby parts. Payload is ~5kg which allows taking multiple anti-armor grenades or small mortar rounds.
