What is THAT ?

 

THAT is a Hexacopter, sometimes called a Hex-rotor. It is a heavy-lift remotely piloted aerial photography platform.

AC1 V3 Heavy-Lift SkyCrane

It is very like a remote controlled helicopter, and is flown in a similar way, but because it has 6 rotors, it is inherantly much more stable and controllable than a helicopter of similar size.

You may have come to this site following links from aerial photography, you may need my unique help or services with whatever project you’re working on, or you may have just met a man in a field flying a strange but intriguing machine, and popped over for a chat.  How ever, or why ever you are here, this is a good place to start.

AC1 Discovery 1.0 launched for her first flight on the 17th July 2012, and was my first semi-pro aerial rig. It was based on the DJI Flamewheel F450 model frame and used DJI motors, ESC’s, Flight Controller and GPS.

As its main use is for aerial photography, it also carries an FPV (First Person View) system that allows me and others to see what it sees from the ground, as it flies, and also a GoPro2, which records 1080P HD video and /or takes 11 MP photographs. This is linked to my ground control via a 2.4 GHz Transmitter / Receiver combo and a 5.8 GHz video / sound link.

Since the beginning,  AC1 has been through a series of upgrades that have now turned her into AC1-V4, an F550-based power-lifter christened ‘SkyCrane‘, with arm extensions, Tiger Motors, 11 inch Carbon Fibre propellers, and a refitted power system. Almost a meter wide, this new version has some serious lifting power and thrust behind it. Cameras are now the GoPro2 and the latest GoPro3 (Black Edition) on a special 2 axis stabilised gimbal. This provides up to 4K cinema resolution footage and 12 MP stills.

So what that adds up to is a fast moving but stable and precision-controllable flying machine capable of traversing all types of terrain, water, and air in the sort of spaces that it would be very difficult to get a camera into any other way.
