Radio-controlled aircraft (abbreviated RC aircraft or RC plane) is a model aircraft that is controlled remotely via radio control. It is typically controlled with a hand-held transmitter and a receiver within the craft. The receiver controls the corresponding servomechanisms that move the control surfaces based on the position of joysticks on the transmitter, which in turn maneuver the plane.

RC planes as a hobby have been internationally growing due to the availability of smaller, relatively inexpensive parts and advancing technologies. A variety of models and styles are available to suit any preference or budget. Due to the availability and advances in high performance electric batteries and motors, a growing number of hobbyists are flying electric powered craft instead of fuel (most often methanol or gasoline based but also diesel) powered craft, because of their ease of construction and the absence of fuel mess and fuss.

Below are some pictures of the types of model aircraft available and the fun that can be had with them! See more photos here.

Aerial photography

February 19th 2007 09:55

Aerial photography was first practiced by the French photographer and balloonist Nadar in 1858. Today aerial photography is used in cartography, land-use planning, archaeology, movie production, environmental studies, espionage, commercial advertising, conveyancing, and other fields.

Below are some excellent examples of aerial photography, see some more examples here.

Model Plane

September 26th 2006 03:24

Model aeroplanes have been constructed since the days of the Wright brothers. They range from simple planes from a kit that fly unassisted, to complicated scale replicas of real planes with equally complicated controls.

The model below is one of the largest jet models in the world today. It is a 1/9th scale radio-controlled model C-17 Globemaster III that was built in the United Kingdom. It was built as part of a 15 program television series produced in the U.K. for the Home and Leisure satellite TV channel.
It took one year to build and is powered with 4 Jetcat P-120 turbines with a total thrust of 108 lbs. Complete with retractable landing gear and pneumatically operated flaps, the rear cargo doors open and can drop a remote controlled (r/c) jeep on a pallet, as well as 2 free-fall r/c parachutists. It was constructed mostly of balsa and ply and included many glass and carbon fibre mouldings to reduce weight, it was covered in fibreglass and epoxy resin.
The model weighs over 250 lbs fuelled, and carries 12.5 litres (3.3 US gallons) of 95% kerosene and 5% turbine oil fuel.
The model has a 2.4 GHz data link to provide real-time data to a laptop computer on the ground while in flight. Data transmitted includes airspeed, turbine RPM, EGT and fuel consumption.
Other details include 5 Futaba PCM receivers, 16 battery packs (93 cells), 20 Futaba servos, on board air compressor and electro/pneumatic retracts. Its wingspan is 20 feet 8 inches, and the top of the fin is 74 inches (6 feet 2 inches) above the ground. Takeoff weight is 264 lbs.

The model in flight, you can't even tell it's not the real thing!

The landing was a bit shaky but no damage done.

Now you can get some perspective of its actual size.

Formation Parachuting

September 7th 2006 03:45

Skydiving or parachuting has complex skills that can take thousands of jumps to master.
Parachutists can participate both in competitive and in purely recreational skydiving events. World championships are held regularly in locations offering flat terrain and clear skies.
One type of parachuting is formation skydiving which is making formations during freefall, or canopy formation which is making formations with other parachutists while under canopies - also known as canopy relative work.

A canopy formation is a formation built by parachutists by flying their parachutes in proximity to each other and then taking grips ("docking") on other jumpers' parachutes. Some photos of a canopy formation are below.

Smoke Angel

August 29th 2006 03:05

The cloud you can see below is a result of a series of flares released by an air force jet over the Atlantic Ocean in May 2006. The jet that released the flares, a C-17 Globemaster III, is seen on the right.
The flares release smoke and the resulting pattern is known as a smoke angel. The circular eyes of the smoke angel are caused by air spiralling off the plane's wings and are known as wingtip vortices.

C-141 Starlifter Leaves a Contrail Over Antarctica

May 25th 2006 04:32

A C-141 Starlifter leaves a contrail over Antarctica. (from Wikipedia)

A C-141B Starlifter aircraft leaves four plumes of exhaust behind it as it prepares for an airdrop during Operation Deep Freeze. Can airlift combat forces, equipment and supplies, and deliver them on the ground or by airdrop, using paratroop doors on each side and a rear loading ramp. It can be used for low-altitude delivery of paratroops and equipment, and high-altitude delivery of paratroops. It can also airdrop equipment and supplies using the container delivery system. It is the first aircraft designed to be compatible with the 463L Material Handling System, which permits off-loading 68,000 pounds (30,600 kilograms) of cargo, refueling and reloading a full load, all in less than an hour. The C-141 has an all-weather landing system, pressurized cabin and crew station. Its cargo compartment can easily be modified to perform around 30 different missions. About 200 troops or 155 fully equipped paratroops can sit in canvas side-facing seats, or 166 troops in rear-facing airline seats. Rollers in the aircraft floor allow quick and easy cargo pallet loading. A palletized lavatory and galley can be installed quickly to accommodate passengers, and when palletized cargo is not being carried, the rollers can be turned over to leave a smooth, flat surface for loading vehicles. In its aeromedical evacuation role, the Starlifter can carry about 103 litter patients, 113 ambulatory patients or a combination of the two. It provides rapid transfer of the sick and wounded from remote areas overseas to hospitals in the United States.
