PowerBox Cockpit 4620

$ 419.99

PowerBox Cockpit SRS is identical in design and construction to the PowerBox Competition SRS, with the addition a programmable door sequencer for warbirds or jets.

In a Serial Receiver System (SRS) servo data is sent via a digital serial signal generated by the receiver. This protocol reduces the connections between the receiver and the PowerBox to a single cable. It is also allows for a second receiver to be added to the model’s control system. As such, the second receiver will control the model’s servos if the first receiver should fail to pick up a signal. (In the case of Spektrum® and Jeti® equipment additional receivers are not required; only the satellite receivers are connected to the Cockpit SRS.)

The integral door sequencer provides unique programming options. The operation of the doors is programmable; i.e., it is not restricted to pre-set sequences. And, the programming is easy thanks to the software-based setup assistant.

The Cockpit SRS can control up to twelve channels, regardless of the radio control system. Four of the channels are equipped with a servo-match function. The purpose of servo-matching is to adjust the center point, end-points, and rotation directions very accurately for each servo. So multiple servos that are ganged mechanically to a single control surface can be fine-tuned to operate in parallel perfectly, which prevents servos working against each other. Servo-matching can also extend the effective life of servos immensely. Servo-matching also allows functions to be linked, avoiding the need for two channels at the transmitter. As an example: the left and right landing flaps can be operated using just one transmitter channel because the directions of rotation and the servos’ endpoints can be adjusted in the Cockpit SRS. This saves channels and makes transmitter programming much easier.

Cockpit SRS settings are programmed using the SensorSwitch in conjunction with the high-resolution OLED screen. Menus are displayed on the OLED screen in full text on the screen.

The Cockpit SRS offers a telemetry link for various radio control systems. This enables the pilot to view the voltage and residual capacity of both batteries on the transmitter's screen. The telemetry interface connects to the receiver using a patch-lead. The Spektrum TM1000 telemetry module is required. Alarms, such as battery failure, are generated at the transmitter.

The Cockpit SRS delivers a regulated output voltage of 5.9 or 7.4 volts, making it compatible with six-volt and high-voltage servos. The regulated voltage ensures optimum performance and extends servo life.

The Royal SRS’s USB adapter provides a port for easy updating of the unit and future expansion possibilities.
