Why?

Why the coaxial dual-blade and gyro can make the RC helicopter flight more stable and smoothness?

• The coaxial RC helicopter has 2 sets of main rotor blades mounted one above the other. The main blades spin in opposite directions to each other, thus cancelling out each other's torque force. So, because there is no torque when both rotors are spinning at the same speed, the fuselage of the helicopter has no tendency to spin round in any particular direction. And that makes the RC helicopter while on hovering will be more stable
• Directional control is achieved by changing the speed of one of the rotors, in relation to the other. In doing so, a small amount of torque is then generated and that force will naturally cause the helicopter to yaw one way or another, hence changing direction

The Gyro:

• The use of yaw control in RC helicopters is made easier by a gyro which is an electronic device that is connected between the receiver and the tail rotor control. The gyro senses any rotational movement of the helicopter that isn't result of a signal to the receiver, and it makes fine adjustments to the tail rotor speed or blade pitch to suit the torque force at that precise moment, hence dampening out any unwanted yaw. Gyros make these calculations and corrections at lightning speed, so much so that the pilot doesn't notice anything other that a stable helicopter

Tips:

Preflight Adjustments:

• Before you are enjoy the flight, the preflight adjustments will helps you reduces a lot of problem while your RC helicopter flying in the sky

• Always check all the controls to make sure they move in the correct direction and here is no mechanical binding or noise from the servos

Hovering Training: 

Step 1:

Hovering is when the RC helicopter is floating in a stationary position in the air. Hovering is the fundamental maneuver to learn first. Here is the procedure to practice hovering

• (1): Make sure there are no spectators anywhere near the RC model helicopter. You, the pilot, should stand at least 10 meters (30 feet) behind and slightly to the side of the RC heli
• (2): Prior to lifting off, while the main rotor is spinning and the RC helicopter is on the ground, check the main rotor fore/aft and left/right cyclic to make sure the main rotor is tilting in the correct direction according to your cyclic command. Move the tail rotor control stick to make sure the RC helicopter nose will swing in the desired direction
• (3): Increase the throttle/collective to lift he model RC helicopter skids off the ground to no more than 10cm (4 inches). Initially, it will be very difficult to control the RC helicopter to prevent it from moving. For a beginner it will also be difficult to determine whether the RC helicopter is in trim or not. But with repeated practice close to the ground you will develop a feel for the controls. It is recommended to let a more experienced model helicopter pilot trim out your new RC helicopter before you attempt to learn to hover

Step 2:

It will take a few hours of hover practice with the helicopter skids at 10 to 20 cm (4-8 inches) off the ground in order to comfortably control the model

• (1): Do not try to lift the RC helicopter to more than 10 to 20 cm (4-8 inches) in the beginning because then the model may tip over readily when the beginner panics and an incorrect command is given. Once you can keep the model in one place, then it is time to slowly increase the height by a few centimeters (inches) each flight. Soon, you will be able to hover the RC helicopter confidently a few feet high. Beginners should always practice hovering close to the ground because in an emergency, throttle and collective can be reduced rapidly without causing a large drop or damage to the RC helicopter. If the RC helicopter is hovering beyond one meter (3 feet) altitude, always descend slowly. A panic drop can damage the helicopter
• (2): Always stand behind the RC model helicopter when learning how to hover. Then you can watch the nose of the RC helicopter. A left tail rotor command will yaw the RC helicopter nose to the left, and a right command will yaw to the right. Similarly, a left cyclic command will cause the RC helicopter to translate left. After you can comfortably hover the model at one meter high without drifting, then start practice hovering while standing to either side of the model. Eventually, you need to be comfortable at hover the RC helicopter from any orientation, including with the RC helicopter nose pointing at you. This is challenging because control directions are reversed
• (3): Once you can confidently hover a RC model helicopter at any altitude and at any orientation, then congratulate yourself because you have mastered 80% of the fundamental control movements of a helicopter

Foward Flight Training:

• (1): Start practicing moving the helicopter laterally to the left or right slowly from a 1.5 meter (60inches) high hover. This is the beginning exercise of translational flight
• (2): After a few hours of practicing step (1) and you are comfortable with translational movement, start using some tail rotor control so the helicopter nose will point slightly to the left or right as you fly it to the left or right. Eventually, this pattern will become a figure-eight in front of you. Please visualize these movements in your mind

Suggestions:

• Buy a Flight Simulator such as the Real Flight G2 simulator. A Pentium IV PC is more than enough. Flight simulators allow you the luxury of crashing without the danger and expense
• Use training landing gears to enlarge your helicopter footprint, making it easier to make safe landings
• Have an experienced helicopter flyer teach you how! Look for a local club or flying field and talk to the experts. Or ask your local hobby shop owner... the good ones will really help you out

NOTE:

• Recharge it again before the power is off. Otherwise, it would be damaged dramatically, even resulting that you can never recharge it again
• Please do not touch, when the motor rotates in high speed and the battery is charging
