Quadcopters are cheap, 30-300 bucks, some can fly with your smart phone...

Hexi's/Octo's/and even the larger Tri's for one that actually works, will cost you a minimum of 1k, usually refurbished... new ones are around 1500, thats without a remote, you use your standard Futaba or the likes multichannel flight twin stick remotes, that are about 300 bucks to 1k themselves...

hence why "most" everyone else has the Quad's....
