For good reason, the QR-1 Quad-Rotor Helicopters are flying off the shelves (no pun intended). Why, you ask? Well, it could be the 2.4 GHz transmitter that fully eliminates those pesky frequency issues. Or maybe it’s the 6-axis stabilization feature of the quad-rotor thrust. Actually, it’s probably the fact that you can easily master stable hovering and flight in Normal mode, which isn’t always the case with remote aircraft. Whatever the reason, this makes a great gift for flight enthusiasts, kids, and adults alike.
