Meet the Proto X from Estes, the brand you know and trust. Not only is the Proto X super-small, it’s also one of the world’s lightest quadcopters! The Proto X is tiny, ideal for indoor flying – and it weighs less than half an ounce. Bright, built-in LEDs make it easy to see the Proto X in low-light conditions. A 2.4GHz radio not only allows for interference free flight – it makes it easy for multiple Proto X helis to fly at once. A 3.7V 100mAh LiPo battery, USB charge cord and spare rotor blades are also included in the ready-to-fly package. All you need to add are two “AAA” batteries!
