Flysky FS-A8S 8CH Mini Receiver with PPM i-BUS SBUS Output

Price: $10.17

This is the first small original AFHDS2A receiver from Flysky. Their first version had issues with rare brownouts on powerful brushless quads, but no issues were noticed with brushed motors. Also it was impossible to swich to SBUS mode as receiver was always forgetting the setting after power off-power on cycle. It was real shame to release such an anticipated receiver with such a major flaws. Currently Flysky is manufacturing and selling version 2 of this RX with SBUS/iBUS switching fixed, improved casing and probably brownout issue fixed. This RX has failsafe, despite stated as without it, but only in iBUS(SBUS) mode.

Update (2017-08-28): Currently the brownout issues are not fixed with this receiver. We are waiting for the version V3 of this RX. Read the dedicated RCG thread here.

1. Press and hold the key on the receiver and connect the power to the receiver. The blue light on the receiver flashing, get into bindind mode.
2, Set the transmitter into bind mode (confirmed AFHDS 2A protocol). After getting into bind mode, the receiver light changes from flashing to slow flash.
3, Transmitter get out of bind mode, then the receiver blue light becomes bright. Indicates that the signal receive is successful.

Failsafe settings:
The receiver can normally receive the transmitter signal, push the rocker to the the failsafe set, long press the receiver bind button, the blue light flashes quickly several times and then always bright , failsafe settings is successful.




Oversky Micro receiver 0.6g FlySky AFHDS 2A 8CH receiver

Price: $15.99

One of the smallest FlySky receivers with a weight of only 0.6g (including antenna). Supports 7 independent PWM signal output or PPM and SBUS output (selected by shorting S/P-EN ground connection). Has failsafe function (throttle to zero, other channels to center). Compatible with AFHDS 2A protocol.




Hardware structure: MCU+RFIC+ ANT;

Size: 15.0*12.0*3.2mm (not including antenna);

Weight: 0.6g (including antenna)

Supports 7 independent PWM signal output

Supports PPM and SBUS output at same time(S/P-EN ground connection)

Working voltage: 3.0~5.0V

Control Failure protection:
When the receiver loses signal, throttle (CH3) will be cleared (value is 850), CH1-CH2-CH4 will return to center (value is 1500), the rest channels will keep unchanged.

How to set up SBUS and PPM signal output:
Solder “S/P-EN with GND together (check the above picture), SBUS signal will come out from CH1, PPM signal will come out from CH2.
