Something about rc helicopter parts

Torsion-tension straps
Blade weight creates tensile forces from the knife. Used as a centrifugal force and speed or weight of the upper lamina in accordance with the greatest strength. Engineers
RC helicopter gyro is a challenge, because while the card must be attached to a solid cube is able to change the tone.
Each manufacturer has developed its own approach to the problem. In 1960, Bell Helicopter has developed a kind of tension Time torsion (TT) for use of the 206 series helicopters. The belts are made of strong, flexible, resemble a pair of elongated strips reinforced holes at each end. One end is connected to the hub and the other end of the blade. They are very strong in the train and at the same time can rotate (spin) the transition phase of the balance rc helicopter blades.
In the mid 1970s, three incident 206B in which failure is associated with a shutter TT belt breaks down the main rotor of the centrifugal forces. In August 1976, the band corresponding to the Bell state of the components of life 1200 hours of limited space. Then, in 1980, after the failure of the fourth part of the banda Bell TT-212, the company only has a life of retirement 24 months.
Sino study showed that four failures are the result of operations in hostile environments. The company's engineers worked to resolve TT strap through experimentation with new materials and corrosion resistant coatings. However, customers have complained that the requirement that 24 months is too short, increasing operating costs and without the need for operators to regularly maintain the sand and salt water nearby. But Bell Metal Gyro RC Helicopter is convinced that it is advisable to err on the side of caution, and given the fact that it is advisable to save the life of the 24 calendar months removed until you can build a secure exchange.

Simulator sickness
Simulator sickness is a form of motion sickness and / or physical held in visual simulator. Regarding symptoms usually belong gastro-intestinal tract film. Symptoms include nausea, dizziness, eye fatigue, hot flashes, headache, confusion and fatigue. So it is a conflict between the senses of expectations vestibular, visual and pilots flying past experience. Thus, drivers with a high percentage of the actual experiences of students are more susceptible aircraft simulator with a little air time. Flight time in particular, some drivers may have a very fast machine and other difficult times.
Each simulator has the potential to cause disease simulator, simulators rc helicopter rotor blades wing, but the disease obviously superior to fixed wing simulator. Simulators helicopters, usually large visual areas, which increases the risk of conflict. Some objects require guidance maneuvers, which amplifies the difference between what the driver sees and feels expectations.
Various methods and limits are designed to help reduce this phenomenon in the helicopter:
• Limit the length of sessions, 2 hours per day
• gel for the eyes of the pilot include images or repositioning
• Limit hovering and training simulator for auto-rotate to adjust the direction
• careful maintenance, optical distortion eliminate any irregular or poorly calibrated optics
• Health and well rested
• Safe for ventilation and cooling in the simulator
Flight simulators are sure loss, cost, and power is a valuable tool for learning. As the helicopter pilots are simulator, the simulator reduces the tendency for the disease. Evolving as technology and computer simulators buy rc helicopter gyro can improve.
