The poles can be varied at a ratio of 1:2 and thus the speed can be varied at 2:1. [ 7 ] [ 8 ] [ 9 ] Normally, the electrical configuration of windings is varied from a delta connection (Δ) to a double star connection (YY) configuration in order to change the speed of the motor for constant torque applications, such as the hoists in cranes .
Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics. [citation needed] Most servos are rotary actuators although other types are available. Linear actuators are sometimes used, although it is more common to use a rotary actuator with a bellcrank and pushrod.
2.400-2.485 GHz: 13-cm UHF Spread Spectrum band for general use (amateur radio license holders have 2.39-2.45 GHz licensed for their general use in the USA) and using both frequency-hopping spread spectrum and direct-sequence spread spectrum RF technology to maximize the number of available frequencies on this band, especially at organized ...
Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
The RC-3 Seabee was designed by Percival Hopkins "Spence" Spencer. An aviation pioneer who first soloed in a powered airplane in 1914, he designed the Spencer S-12 Air Car Amphibian . Construction of the S-12 began on March 1, 1941 and the small, two-seat S-12 prototype, registered NX29098, made its first flight on August 8, 1941.
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.
A competitive offshoot of the radio control model warships hobby that involves the firing of projectiles, usually propelled by gas, at opposing ships to sink or damage them. Models are usually simplified to facilitate repair. Ships are fitted with bilge pumps; bb, 3/16", 7/32" or 1/4" weapons that fire ball bearings.
The MX-7 uses the same fuselage as the M-6,which is a modified M-5 fuselage but the same wing span as the M-5, [2] [3] and incorporates the increased fuel tankage, Hoerner-style wingtips and five-position flaps designed for the M-7. [4] The M-7 family has been produced both with piston and turboprop engines. [2] [3] [5]
