Product Information

Great RC plane for beginners

Learn to fly in less time! With a futuristic delta wing design, exclusive technology and compact size all signs point towards an RC plane that is perfect for those starting out in the hobby. You get that with the Delta Ray One from E-Flite and a whole lot more. This RC plane is super easy to fly but has a flight envelope that will cater to your improving skills once you get a hang of the basics.

Based on the combination of efficiency and stability that the Delta Ray One provides you will find this delta wing design RC airplane brilliant to learn on. Activate the exclusive Sensor Assisted Flight Envelope (SAFE) technology and you’ll notice a lot of the stress is taken out of the learn to fly stage of your RC journey. You also run the risk of having fun! To add in that extra level of safety you can upgrade your Delta Ray One with SAFE Plus GPS-enabled drone technology. This utilises Virtual Fence and AutoLand so you can program in set boundary parameters which then opens up the possibility of safely flying in smaller fields and parks.

E-Flite Delta Ray One

Lightweight, yet durable

Constructed from advanced lightweight and durable EPO foam, the Delta Ray One is extremely resilient which means it can handle a few prangs and scrapes particularly with its rubber nose cone. To make it even easier for the beginner flyer this RC plane can be taken straight out of the box, bound to the supplied transmitter and into the sky you can soar!

Beginner RC planes don’t have to be boring and the Delta Ray One is far from it. The delta wing design combined with the brushless power system gives the pilot an efficient and powerful aircraft that will do rolls, loops and inverted flight. The flight envelope on the Delta Ray One is wide enough to allow beginners to flourish and also challenging enough to give more experienced pilots some aerobatic opportunities.

The Delta Ray One also comes in the BNF Basic version (EFL9550) which lets you set this RC plane up using your own transmitter, batteries and FPV related equipment.
