CTRD4 – Double channel servo driver the trimming of the aileron or pitch
CT Relay Deck Power is a product designed to control the trim of the aileron and pitch of the aircraft. It is inserted into the circuit between the buttons (on the stick) and the servos. Pressing the appropriate button on the stick will activate the CTRD4 unit and this will supply power to the servo in the desired polarity. The servo starts to move with the trim wings. When the button is released, the process stops. Trimming is mainly used to increase the comfort of controlling the aircraft (e.g. in wind…). The product controls two channels. This means that it can be used for trim system aileron and pitch. The CTRD4 product supports the possibility of connecting a servo speed controller.
