Futaba R7206SB FASSTest receiver 6k

Six-channel FASSTest-2.4GHz Futaba transmission system telemetry receiver with a pair of full-range diversity antennas. It is intended for general use in models of all categories; thanks to its compact dimensions, low weight and connectors inserted in the longitudinal axis, it is also suitable for models with a slim hull, such as F3B, F3J gliders, etc. Thanks to selectable channel modes and the possibility of dual receiver operation, it will also serve excellently in models requiring a large number of channels - in such a case a pair of R7206SB will provide up to 16 classic PWM channel outputs or 10-12 PWM outputs, S.BUS serial output and S.BUS2 for two-way communication enabling the connection of S.BUS2 servos, telemetry sensors and other compatible devices, as S.BUS2 ports can also serve sockets of channels 1, 2, 4 and 6. Operating states of the receiver are signaled by an LED indicator.

Transmission system

Futaba FASSTest-2.4GHz with telemetry for flying models.

Note that only digital servos can be used in FASSTest 12CH high repetition rate mode.

Power supply

3.7-7.4 V (nominal voltage), the operating voltage range is 3.5-8.4 V – i.e. e.g. 4-6 NiMH, 1-2S LiPo, 2S LiFe and Li-ion batteries, BEC power stabilizers in the given voltage range.

Antenna

The receiver is equipped with a pair of diversity antennas in order to maximize signal reception regardless of the relative position of the model and the transmitter. These must be fixed in the model with a mutual orientation of 90°.

Receiver outputs, channel modes

The receiver is equipped with sockets for standard Futaba connectors (with a protrusion), into which you can of course also insert UNI connectors (=JR/Graupner, Hitec) without a side protrusion.

Channel outputs (PWM/S.BUS/S.BUS2): The R7206SB allows changing the channel assignment as shown in the table below allowing the use of a combination of classic PWM outputs and S.BUS output or dual-receiver operation (requires the use of a Futaba transmitter enabling dual-receiver operation) in which the R7206SB pair can offer up to 12 classic PWM channels or 10-12 PWM outputs and 1-2 S.BUS/S.BUS2 serial outputs, or other combinations with additional S.BUS2 input/output ports. Channel modes are selected using a button on the receiver in a special setting mode – channel modes cannot be changed in normal operating mode.

Dual receiver operation with automatic backup

It is also possible to activate the two-receiver mode with automatic backup on the receiver, which automatically switches from the main receiver to the backup receiver (or vice versa) in the event of a signal failure of one of the receivers (pair of R7206SB or one R7206SB and another FASSTest S.BUS2 receiver). The function is basically the same as that of the FDLS-1 backup system, but you don't need any additional equipment.

Telemetry (only in FASSTest system)

The R7206SB transmits data about the receiver's supply voltage to the transmitter without the need to connect any sensors.

The R7206SB allows the use of all Futaba telemetry sensors and other sensors compatible with the bidirectional S.BUS2 bus system.

The receiver set includes: receiver R7206SB, user manual.

What is S.BUS2/S.BUS

• S.BUS – Futaba serial bus with one-way communication enabling the control of servos, controllers, switches, gyroscopes and other compatible RC devices connected to a single output port of the S.BUS receiver.
• S.BUS2 - Futaba serial bus for two-way communication allowing (as S.BUS) control of servos, controllers, switches, gyroscopes and other compatible RC devices connected to a single output/input port of the S.BUS2 receiver. In addition, it allows you to connect telemetry sensors and transmit data from them through the receiver for display on the transmitter; from some S.BUS2 servos can transmit information about the operating current, temperature or angle of the servo output lever to the transmitter.

Unlike classic RC kits, the S.BUS(2) system uses serial data communication to transmit control signals from the receiver to a servo, gyro or other device. This data contains commands like "move channel 3 servo to 15 degrees, move channel 5 servo to 30 degrees" for multiple devices. S.BUS(2) devices only execute commands belonging to their own set channel. For this reason, it is possible to connect several servos to the same signal cable, while setting and controlling them individually as needed. The servo identification code (ID) is used for this. You can find the ID on the sticker on the servo box.

The S.BUS2 servo can be connected to the S.BUS2 and S.BUS ports of the receiver. Its function is determined by setting the channel in the servo memory (it is performed using the programming interface of the Futaba transmitter, the SBC-1 programmer or the CIU-3 USB interface with the S-Link PC program - for some servos, the channel can only be set with the help of the transmitter).

An S.BUS or S.BUS2 servo connected to the channel output of a classic receiver (PWM) works like a classic servo. Its movement is given by the signal in the channel of the receiver to which it is connected. The settings of the programmable servo functions remain in effect.
