NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power . [ 1 ] [ 2 ]
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...
Many notable individuals in the 1960s through the 1990s and beyond created the landscape of modern RC modeling. These included many starting their own companies. The families of many of these individuals lost interest in continuing these businesses. The incoming supply of ARF planes from overseas made it hard to sell kits requiring assembly.
RealFlight RC Simulator is a radio-controlled airplane and helicopter simulation software series developed by Knife Edge Software and now published by Horizon Hobby. The software allows for the flying of numerous RC aircraft, helicopters and drones so that the user can learn to fly RC, practice their skills or fly with others in multiplayer mode.
30 size : Engine 0.3 cubic inch, Main Blades 550-600mm; 50 size : Engine 0.5 cubic inch, Main Blades 600-620mm; 60 size : Engine 0.6 cubic inch; 90 size : Engine 0.9 cubic inch, Main Blades 690-710mm; Modern RC helicopters are generally classed by the length of the main blades (with few exceptions). Common classes are: Micro (under 200mm main ...
1:10 scale radio-controlled car (Saab Sonett II)A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
The US National Electrical Manufacturers Association (NEMA) standardises various dimensions, marking and other aspects of stepper motors, in NEMA standard (NEMA ICS 16-2001). [11] NEMA stepper motors are labeled by faceplate size, NEMA 17 being a stepper motor with a 1.7 by 1.7 inches (43 mm × 43 mm) faceplate and dimensions given in inches.
For example, 1:48 scale is 1/4" to 1-foot (or 1" to 4 feet) and 1:72 is 1" to 6 feet, while in metric scales such as 1:100th, 1 centimeter equals 1 meter. 1:72 scale was introduced with Skybirds wood and metal model aircraft kits in 1932 and were followed closely by Frog, which used the same scale from 1936 with their "Frog Penguin" brand. 1:72 ...
