Purpose of Campaign
The purpose of this campaign is to offer customers the lowest possible price. The RX Controller has many potential uses, from boating safety and training to a wide variety of kiting sports. Out on the water, the main advantage is the ability to easily launch and retrieve directly from the boat.
A wide variety of small sailing systems are now available for boats. The advantage with kite sailing is more power and quick deployment from any type of boat. Kayaks and canoes can be quipped with a rudder and centerboard for amazing performance on all normal sailing courses. Even a paddle in the water as a rudder can be used for sailing across the wind and downwind.
