Aerial Photography can be defined as a type of photography in which images are clicked of the ground from high altitudes. Earlier for this purpose, so many instruments and platforms were used like parachutes, kits, poles, helicopters and many more. The other names in this category were planes, balloons and dirigibles. Still people are dependent on planes and helicopters for shooting different scenes or clicking pictures. Time has changed and so do the technology. We have something very creative and smart to perform the same task, but in a much easier and cheaper way. This is known as multirotors. This multirotor is a rotorcraft with more than two rotors in which fixed-pitch blades are used and vehicle motion is controlled by changing t relative speed of each rotor. This changes the thrust and torque that is produced by each rotor.

The most frequently used names of multirotor in radio control aircraft projects are octocoptor, hexacopter and Quadcopter Kits. These are the low budget options of performing aerial photography. If you have any knowledge related photography, then you must be aware of the applications of these multirotors. Digicams are easily available that can be afforded by average consumer to perform aerial photography. Both these tools are used to perform cartography. Creating topographic maps is a quite difficult task as without proper photographs these are quite difficult to make. With the help of processing software and photographs clicked through these structures, topographic maps can be easily constructed.

If we just talk about quadcopter kit, then you must know this kit comprise of :

• Motors
• ESC's
• Propellers

It is DJI is a multi-rotor flying platform premeditated for recreational aerial photography, general flying entertainment and first person view applications. When these are combined with the autopilot system, balancing and cruising becomes almost unproblematic, while gently sloping and other complex maneuvers can be performed in a highly efficient way. It is quite easy to build the frame and the PA66+30GF material is used in the frame arms which are believed to be extremely hard-wearing. The optimized frame design brings lots of space for an autopilot system. PCB frame board has an extensive strength makes wiring of the batteries and ESC's effortless and protected. One should prefer going for a Flame Wheel as multi-rotor aircraft will be a great fun for you.

The complete kit actually comprises of:

• (4) ESC (18A)
• (4) Blades (8 x 4.5)
• (4) Motor (2212)
• Complete Frame

The other things that are required to complete this whole structure is:

• 3S ~ 4S LiPo battery & charger
• 5-Channel aircraft transmitter system (minimum)
• Autopilot system

So many companies and even online dealers are there which deals in these quadcoptor kits and also provide similar hexacoptor and octacoptor kits. You just need to find the one that suits your purpose and even budget. Many reliable companies provide complete information like what is in the kid, which company it belongs to, material used for making them and many other things that buyer should know.
