Smartphone-controlled helicopter enthusiasts can now unleash their fury at annoying (and unsuspecting) office colleagues thanks to the release of the HELO TC Assault . A follow up to Griffin’s HELO TC helicopter, this menacing mini-copter packs 6 “live-fire” missiles which can be launched at will with the free iOS or Android app. Using your iPhone/iPad/Android device as a remote control, you can fly the cool gizmos via either the touchscreen’s virtual joystick or tilt controls. There’s even an auto land feature and the ability to record up to 3 flight plans for maximum fun. The HELO TC Assault is now available for $59.99 and shipping’s free within the US (international orders start at $8 for “economy” shipping). Check out the rather hilarious promo trailer of a boss getting even with his underlings after the break.
