HOBBY PARTZ GT3X Digital Proportional Radio Control System Instruction Manual

HOBBY PARTZ GT3X Digital Proportional Radio Control System

Make sure moving direction of all motors be same with the operating direction. If not, please adjust direction first. The shutdown sequence must be to first disconnect the receiver battery then lo switch off the transmitter, if the transmitter is switched off while the receiver is still powered, it may lead to uncontrolled movement or engine start and may cause an accident.

DIGITAL PROPORTIONAL RADIO CONTROL SYSTEM

Do not operate outdoors on rainy days, run through puddles of water or use when visibility is limited. Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control may occur. Do not operate in the following places. Near other sites where other radio control activity may occur, Near people or roads. On any pond when passenger boats are present. Near high tension power lines or communication broadcasting antennas, Interference could cause loss of control, Improper installation of your Radio Control System in your model could result in serious injury. Do not operate this R/C system when you are tired, not feeling well or under the influence of alcohol or drugs.Your judgment is impaired and could result in a dangerous situation  that may cause serious injury to yourself as well as others. Do not touch the engine, motor, speed control or any part of the model that will generate heat while the model is operating or immediately after its use.These parts may be very  hot and can cause serious burns. Please have an overall check about the model before any operation. Any problem in radio control system or improper installation may cause out of control. Simple distance test methods:One hold the model, and the other one carry the transmitter to a proper place to check the servo system condition. Please stop operation if any exceptional case occurs. Please check the model memory to make sure the matching is right. Turn on the power, please check if the throttle neutral position is in its lowest position .while turning on the transmitter every time.When making adjustments to the model, do so with the engine not running or the motor disconnected, you may unexpectedly lose control and create a dangerous situation.

SYstem Characteristic

This radio system works in the frequency range of 2.405 to 2.475GHz. This band has been divided into 142 independent channels. Each radio system uses 16 different channels and 160 different types of hopping algorithm. By using various switch-on times, hopping scheme and channel frequencies, the system can guarantee a jamming free radio transmission. This radio system uses a high gain and high quality multi directional antenna. It covers the whole frequency band. Associated with a high sensitivity receiver, this radio system guarantees a jamming free long range radio transmission. Each transmitter has a unique ID. When binding with a receiver, the receiver saves that unique ID and can accepts only data from that unique transmitter. This avoids picking another transmitter signal and dramatically increases interference immunity and safety. This radio system uses low power electronic components and a very sensitive receiver chip. The RF modulation uses intermittent signal transmission thus reducing even more power consumption. Comparatively, this radio system uses only a tenth of the power of a standard FM system. This system uses the two-way communication, which could control the working state of current model better and make the operation more enjoyable and safer than before.
