A garden hose would stop it real quick. I’m not telling how I know that though.actually there are many things that would kill that thing, it's jammed packed with electronics, lipos and not ready for real combat. A simple stun grenade would f*** those servos up like mofo, the tolerances on those are razor thin to produce so much torque efficiently, they are not geared servos. A cattle prod would def f*** it up.
