E-flite Blade 400 3D Electric Mini Helicopter RTF

The Blade 400 3D is designed to give intermediate to advanced heli pilots a ready-to-fly experience like no other. It comes 100% factory built and flight tested so you can get flying right away. There is nothing left to assemble or set up. The Blade 400 3D is ready for hovering and 3D aerobatics as soon as you finish charging the battery. And you can fly it just about anywhere, anytime thanks to the included Spektrum 2.4GHz DX6i radio system that avoids interference with other RC users, even those on other 2.4GHz systems. You also get the benefit of the DX's advanced DSM2 protocol that provides the kind of locked-in, solid response that will let you fly even the most demanding 3D maneuvers with absolute precision.

The Blade 400 3D is the first ready-to-fly mini-heli to come equipped with Spektrum's advanced DX6i 2.4GHz DSM2 6-channel programmable computer aircraft system. Besides providing freedom from frequency restrictions and interference, the DX6i's DSM2 technology offers other unique advantages like faster control response and innovative features such as ServoSync. ServoSync automatically resequences transmitted data so mixed servos receive their pulses at the same time so you can fly extreme 3D aerobatics with absolute precision. The system also includes the feather-light, 4.4-gram Spektrum AR6100e Microlite Receiver.

E-flite uses top-quality engineering and materials in everything it makes, so you always get the maximum level of value and fun. And E-flite backs all of its products with the best customer service and support in the hobby so your electric flight experience is always a positive one.
