    The E-flite® Delta Ray® One airplane is the perfect choice for anyone who wants to learn to fly RC. Its compact size, innovative delta wing design and exclusive technologies combine to deliver an airplane that’s not only incredibly easy to fly, but is also capable enough to help you succeed and go beyond basic flight. The Delta Ray One makes it easier to learn to fly in less time than ever before, and without the need for any experience at all.

    The E-flite® Delta Ray One airplane features an innovative delta wing design that provides a futuristic combination of stability and efficiency. And beyond its advanced aerodynamics, it’s also equipped with exclusive SAFE® (Sensor Assisted Flight Envelope) technology which makes learning to fly even easier, more relaxing—and most important of all—more fun! Plus, you can easily upgrade to SAFE Plus GPS-enabled drone technology that offers features such as AutoLand and Virtual Fence that makes learning to fly easier and safer than ever. Its compact, ultra-micro size makes it possible to fly in smaller spaces such as parks and soccer fields, while its lightweight construction with advanced EPO material and a rubber nose cone makes it extremely durable. Best of all it arrives 100% factory-assembled and ready to fly right out of the box!

    And the fun doesn’t stop after you learn how to fly! The powerful and efficient brushless power system delivers long flight times and provides plenty of speed and power to perform aerobatic maneuvers including loops, rolls and even inverted (upside down) flight. Plus, the delta wing design and low wing loading deliver a very wide flight envelope and incredible handling that even experienced pilots will appreciate and enjoy. For them, the BNF Basic version (EFL9550) is ideal because it allows them to use their favorite Spektrum™ transmitter along with the batteries and chargers they may already own to fly with.
