lately Ive been seeing alot of ADs for this "KuDrone" a 4k Micro Quadcopter (about the size of a Nano QX) priced at about $109(us) advertised but its more towards $200. its an IndieGoGo campaign $50,000 goal but they achieved that and are currently around $120,000. im just wondering how evryone feels about this. apparently it has a 8 min flight time, runs on a 650 mAh, shoots in 4k (turns out 15FPS), sonar hovering, GPS, more listed below. is this possible? i dont think its possible to fly 8 mins while running all these features? IDK what do you guys and gals think?
