And even then, learn on a head holding gyro first, then progress onto the scale heli's and rate mode gyros. The PG-03 features great crash and impact resistance plus new circuit developed to improve temperature and neutral. The unique sensor has been specifically developed for this state-of-the-art gyro system and features an ultra-rapid, super-accurate detection and respinse system. In conclusion, only purchase a head holding gyro unless you are wanting to go scale. Shop from Indias No.1 Online Robotics Store: Arduino, Raspberry Pi and the largest collection of Electronic Components, DC motors, Drone Parts, Sensors. The PG-03 has been designed using a new micro piezo sensor. It will also reset the gyros stored position to the new position you move your heli to. With a head holding gyro, the rudder signal from your transmitter no longer directly controls the tail – it simply tells the gyro how many degrees to turn per second. Heading hold gyros are very popular and pretty much standard among RC helicopter pilots for that very reason – they’ll hold your tail in a constant position no matter what you’re doing as long as you don’t input a rudder command, even if you’re doing 3D aerobatics or flying in a strong wind. Therefore, as you increase the throttle or headspeed of your heli, the head holding gyro will counter the main rotors thrust automatically keeping your heli’s tail in its original position. Based on the deflection from the set position, the gyro will control the rudder servo such that the gyro returns the helicopter to the set position. In a heading hold gyro, a built microprocessor that keeps track of and remembers how far the helicopter has turned from its set position. Heading hold or heading lock gyros are a conceptually simple extension of rate gyros. The reason for this, is that the servo will always go back to center when you release the stick. The only time that we will use rate mode on the gyro is when we are setting it up. Rate gyro’s are often used in scale RC helicopters because they lend themselves to a more realistic flying experience, while heading hold gyros are used by almost everyone else because they make flying easier. There are two types of gyro functions, rate mode and heading hold.
