That kind of drone is a slug. Racing drones with HD video and FPV ( first person view, headset makes it like you’re in the cockpit) will be orders of magnitude harder to hit. Judicious use of some fine aluminum or titanium sheet would also render it impervious to birdshot. Racers are up to 100 mph now and can perform insane maneuvers, they’ll draw 100 amps under acceleration.
