I have included the link to the designer of this pad. It's a little more than a pad with lights. As I stated in my post it will be able to link with multiple pads for pattern landings or hover control ect. The lights will go out one by one the closer you get to the pad. So if your doing a game with a friend to see who has the best control of their heli. You can pick the number of lights you want to be illuminated and see who can get that target first. With  the wireless sync mutiple pads can be linked together to do take off and landing patterns. Or skid hops from one to another for fun challenging routines or garage comps with friends. No sir these heli pads are for smaller indoor helis. So no offense taken at all it won't be for everyone as with a 700 sized heli lol. With a few of this linked you could do a low control pattern chase sorta like flying through gates or obstacles. With smaller indoor helis in mind.
