HPI Savage is a line of radio-controlled monster trucks manufactured in Japan by Hobby Products International of Foothill Ranch, California, US.. The overall setup of the Savage, with its massive tires and tall suspension, make it a perfect truck for bashing, and also enables the model to be able to withstand tremendous abuse.
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 servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
Amateur television (ATV) is the transmission of broadcast quality video and audio over the wide range of frequencies of radio waves allocated for radio amateur (Ham) use. [1] ATV is used for non-commercial experimentation, pleasure, and public service events.

A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a talkgroup ) with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time ...
In the early 1930s, the Adcock antenna (transmitting in the LF/MF bands) became a key feature of the newly created radio navigation system for aviation. The low frequency radio range (LFR) network, which consisted of hundreds of Adcock antenna arrays, defined the airways used by aircraft for instrument flying. The LFR remained as the main ...
The Oshkosh M-ATV is a mine-resistant ambush protected vehicle developed by the Oshkosh Corporation for the MRAP All Terrain Vehicle (M-ATV) program. Intended to replace M1114 HMMWVs (Humvee), it is designed to provide the same levels of protection as the larger and heavier previous MRAPs, but with improved mobility.
