One of the first decisions to make when purchasing an Unmanned Aerial Vehicle is what configuration will suit your requirements.
Several configurations are available when considering to purchase a multi-propelled copter type of drone.
On paper, a quadcopter (a craft with four or motors and propellers) is more efficient than an octocopter (eight). The added motors mean more energy sucked out of an already limited battery life and the large footprint makes it more challenging to transport. But despite this, there are several reasons as to why the octocopter is the industry’s preferred choice.
- THE EXTRA MOTORS AND PROPELLERS OFFER REDUNDANCY AND SECURITY
There is nothing worse than seeing your craft, gimbal and camera shattered into a million pieces so with an octocopter, it is much cheaper to replace a motor as compared to an entire quadcopter when a motor fails.
Flying without a redundant motor is not only a hazard to your equipment, but also to others so being able to recover from a malfunctioning motor is important.
- FLY WITH MORE
Octocopters can lift more weight. More motors mean more thrust and more thrust means more weight which allow you to fly with more cameras and lenses.
The BBC famously made their hexacopter debut in October last year which allowed them to film locations and angles that previously would not have been possible when they published a story on what a high speed rail line through the UK would do for the country.
This is a fine example of how these little machines have transformed the world of news and the lives of news reporters across the world by being able to provide a brand new perspective.
Equipped with GPS and having a flight time of approximately 30 minutes, the German-built device also comes with wireless communication and camera mounting.
Essentially these models have all of the same major benefits of a quadcopter with a lot more thrown in like power, height and added safety (flight is still possible even if one motor is damaged).
By far the most popular of the multicopters.
They are fast, easy to manufacture and affordable.
QUADCOPTER DESIGNS HAVE ALSO BECOME INCREASINGLY POPULAR IN UAV RESEARCH WITH THEIR ELECTRONIC CONTROL SYSTEMS AND SENSORS USED TO STABILIZE THEIR AIRCRAFT. WITH THEIR SMALL SIZE AND AGILITY, QUADCOPTERS CAN BE FLOWN INDOORS AS WELL AS OUTDOORS AND ALSO HAVE ADDITIONAL ADVANTAGES:
- Quadcopters do not require mechanical linkages to vary the rotor blade pitch angle as they spin which simplifies design and maintenance of the vehicle.
- The use of four rotors allows each individual rotor to have a smaller diameter than the equivalent helicopter rotor, allowing them to possess less kinetic energy during flight which reduces the damage caused should the rotors hit anything.
- For small-scale UAVs, this makes the vehicle safer for close interaction
Due to their ease of construction and control, quadcopter aircraft are frequently used as amateur model aircraft projects.
So which one should you pick?
KEEP THIS IN MIND WHEN MAKING THE CHOICE:
- Quad: These models are inexpensive and less durable. Perfect for beginners and non-professionals.
- Hexa: The ideal choice for semi-professionals or hobbyists that want a very durable, steady-flying copter that can carry heavier weights.
- Octo: The top of the line. These are copters that have a high price tag, but they are powerful, stable and fast. Advanced functionality and stabilization features make an octocopter a must-have for professionals.
As the prices of hexacopters and octocopters drop, you may find models within your price range. If you do, these are the preferred choice over a quadcopter. (source: http://dronebly.com)
