The KDS RC Model KDS900 SMM AVCS Helicopter Gyro + Program Card GY227 is a high-tech gyro system designed for remote control helicopter enthusiasts. This gyro system features advanced AVCS (Angular Vector Control System) technology, which helps the helicopter maintain a stable flying position by automatically adjusting the tail rotor’s speed. The system also comes with a program card that allows users to easily adjust the gyro gain, direction, and other settings to optimize the helicopter’s performance. The KDS900 SMM gyro is compatible with a wide range of helicopters, making it a versatile and reliable choice for hobbyists of all skill levels. KDS RC Model KDS900 SMM AVCS Helicopter Gyro + Program Card GY227. This is 100% Brand new item and we can ship this item to worldwide.

Introduction
KDS900 is designed specially for RC helicopter. It is a high quality and precision gyro. The gyro adopts AVCS, high performance SMM sensor and controller. It features excellent location capiblity, and stable yaw rate which can avoid influence from external variables, such as rotation speed of rotor head on helicopter, flight speed and crosswind. With these advantages, you can greatly enjoy your flight with KDS900 gyro.
The performance of gyro is closely related to servos. The quicker the respone of servos, the better the sensitivity and performance of gyro. It is recommended to use Futaba S9253, S9254, S9257, S9256 or BLS251 to match KDS900 gyro.


AVCS Gyro
Conventional gyros send control signals to the rudder only when the tail of the helicopter moves. When the tail stops moving, the control signal from the gyro becomes zero. Conversely, the AVCS gyro continues to send control signals to the servo even when the tail of the helicopter stops moving. The following sequentially describes the conventional gyro and the AVCS gyro.

Operation of Conventional Gyro


Basic operation is described by considering the case when the helicopter is hovering under crosswind conditions. With a conventional gyro, when the helicopter encounters a crosswind, the force of the crosswind causes the tail of the helicopter to drift. When the tail stops drifting, the control signal from the gyro becomes zero. If the crosswind continues to cause the tail to drift in this state, the ‘stop’ operation is repeated until the tail faces downwind. This is called the ‘weathervane’ effect.

Operation of AVCS Gyro
Conversely, with an AVCS gyro, when the helicopter encounters a cross-wind and the tail drifts, a control signal from the gyro stops the drift. At the same time, the gyro computes the drift angle and constantly outputs a control signal that resists the crosswind. Therefore, drifting of the tail can be stopped even if the crosswind continues to effect the helicopter. In other words, the gyro itself automatically corrects (auto trim) changes in helicopter tail trim by crosswind. Considering operation of an AVCS gyro, when the tail of the helicopter rotates, the servo also rotates in accordance with the angle of rotation of the tail. When the tail stops rotating, the servo judges that it has stopped in that position. This the auto trim function.


 


Features


AVCS System
since rudder drifting caused by wind, or other meteorological factors and different helicopter attitudes will by eliminated automatically, the perfect to tail (rudder) will become more easier, making it operation to 3D Flight.


 


SMM Gyro Sensor


Use of newly developed extremely low drift SMM (Silicon Micro Machine) gyro sensor virtually eliminates rudder trim changes during flight.


 


Support Boardband and Narrowband Digital Servo


You can configure 1520uS servos and 760uS servos via setup card.


 


Remote Gain Function and Mode Switching Function


Remote gain function allows sensitivity switching from transmitter and mode switching function allows AVCS / normal gyro mode switching.


 


Integrated, Compact and Lightweight


Compact size (23 x 23 x 10mm) and light weight (9g) realized by high density mounting technology.
