CTRDP – Single 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 CTRDP 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 only one channel. This means that it can be used separately only for one trimming system. To control both (aileron and pitch), it is necessary to install products twice. Compared to the CTRD2 version, this product can handle higher current switching. The CTRDP product supports the possibility of connecting a servo speed controller.
