Swift Stream RC drones and helicopters are built to professional-grade standards and feature durable bodies. Helicopters and drones fly forward and backward, up and down, and turn. Drones fly the same way, plus side-to-side while going into breathtaking 360 degree flips. The high-quality batteries are interchangeable between most models- this is unique to Swift Stream RC.
