Signs that fly are a brand new invention by Kurt Shafer.
FIRST KNOW THESE ARE GUARANTEED TO INCREASE YOUR TRAFFIC!
If the sign does not in 90 days you can return it for a full refund.
AND NOW YOU GET AN EXCLUSIVE ON YOUR ZIP CODE!
Once you buy one, no other will be sold in your zip code.
The simplest implementation is a 4 ft by 6 foot cloth sign printed on both sides like a flag and held up by a drone and held down by a tether cable.
The tethering cable provides power to the drone so it does not rely on a battery.
The tether is held by a reel assembly that is designed to allow you to reel the sign down if the wind gets too high.
There is a power supply at the ground end of the tether that plugs into an AC power outlet (or can be powered by a 12 volt battery).
WHAT ABOUT WIND??
This sign is guaranteed to operate in wind up to 30 MPH. Over that you will need to take it down using the reel that reels in the tether.
