Film from full sized or remotely piloted helicopter?

It should be made clear that, at present, a remotely piloted Helicam is not a direct replacement for a full-sized helicopter with a camera mount. While there can be some overlap in the operational ranges for either, to try and use one entirely in the domain of the other is neither safe nor wise. For maximum benefit the user should apply each towards its own inherent strengths. If you need a long continuous shot over a tree covered landscape, filming from full size is the best option. If you need a shot flying under a bridge or chasing a car through an abandoned building - then this is the sweet spot for a Helicam.

If budget permits however, it can be quite spectacular to blend both technologies together, combining wide, high altitude panoramic views with tighter shots like those from a birds POV.

Regarding comparative costs, hiring a Helicam with an experienced, professional crew is usually 30% to 50% less than say renting a Jet Ranger with a Tyler mount for a days shooting. I should also qualify what I consider a "professional crew" in this equation. This would be a company that carries insurance, has more than one aircraft available, has numerous examples of smooth, steady, vibration free footage and has captured this footage in a wide variety of settings and weather conditions over a period of several years.

As mentioned previously, the typical range of a Helicam is about 1200 feet in the horizontal plane due to the need for the pilot to have continuous "line of sight" connection to the helicopter. This range can be increased dramatically however by using a variety of vehicles such as boats, ATV's, golf carts, cars, trucks, snowmobiles, etc. to fly from.

Perhaps the greatest advantage of remotely piloted camera platforms is their ability to obtain movements and angles that are uncommon and grab the viewers undivided attention. The most significant advancements being made with these systems is in the area of camera stabilization. Systems are now available that can hold a level horizon at +/- .5 degrees or less with small lightweight cameras. Similar systems for cinema quality cameras is not far behind.

RC Aerial Cinematography Basics?

For aerial cinematography, think of the RC Helicam as a hybrid dolly and jib with an insane range of motion. Since the helicopter is not connected to the ground, it can move the camera freely to any point in 3 dimensional space, providing some often spectacular angles, dynamic movements and unique views. These aircraft are most often flown in what is commonly known as "line of sight" or LOS. For a larger, brightly colored helicopter, this range can be as much as 1200 feet in the horizontal plane and 400 feet vertically when operated by a well experienced pilot. Why is the vertical distance less than the horizontal you might ask? Well this is primarily due to the policies of the FAA in the United States. It is in everyone's best interest if these unmanned aircraft do not try to occupy the same airspace, at the same time, as full size manned aircraft.

From a creative perspective, the potential of such a device quickly becomes apparent. Taking only about 15 minutes to set up or tear down, you can quickly appreciate the versatilty of such a platform, particularly in remote filming locations. The next question is usually one of image quality. Capturing photographs from a helicam is not a overly complex task for a competent pilot, but capturing smooth, stable film or video is an entirely different matter and requires the skill set of a true ninja/guru/master in several different arenas. This quickly explains why there is truly only a handful of companies that can consistently and reliably provide such a service using cinema quality cameras like the Red Epic. For these elite few, it is possible to provide very high quality imagery that is worthy of the big screen. As technology advances, sophisticated electronics and software will make cinema quality aerials within the reach of the less skilled, and at a price that many can afford.

There are a variety of helicopter types and sizes used for HD aerial video and film-making. They can be powered by internal combustion engines, turbine engines and electric motors. Our personal experience has shown that turbine powered models, while smooth, are overly complex and not practical for daily use "in the trenches". Electric powered models are both smooth and quiet but have limited flight duration. Around 10 minutes flight time is typical for one set of lithium based batteries. Since aerial shots are typically short, this is usually not an issue and only a few moments are required to change batteries. Internal combustion powered models may be either methanol or gasoline powered. Once again, our personal experience has been that opposed twin cylinder engines are much smoother than single cylinder types. We have been able to obtain smooth, vibration free video from such platforms that rivals our electric powered models. A side benefit of these platforms is the ability to be continuously available for up to one hour. These platforms are also larger than current electric powered aircraft and so, are more stable, particularly in moderate winds. This is not just our opinion, it is the law. More specifically Newton's law. For HD video, the practical benefit of gas power is being able to do multiple takes, loitering in the sky if needed to reset the shot. Over the course of a day of filming this can be a huge time savings. For 35mm filming this is less important as the cameras can only carry film loads of up to 200 feet. Recent advances in direct drive gimbals we very likely bring renewed interest in gas powered rigs, as it will become much easier to get footage that requires no post stabilization from a rig with a small amount of vibration.
