The Blade 400 3D — Horizon Hobby's 400-class electric collective-pitch helicopter for outdoor 3D flying.
The Blade 400 3D is part of the Blade product line, sized for the 400-class — slightly smaller than the dominant 450-class but capable of similar 3D handling. A natural sibling of the broader Blade collective-pitch heli family.
A small electric helicopter for indoor and small-field rotorcraft practice.
