Product Description



Small, lightweight 3 /18 - channel 2.4 GHz FASSTest® S.BUS receiver weighing only 7 g, with full range and integrated telemetry transmitter. 

Ultra-slim for models with narrow fuselages. With the S-BUS system for up to 18 channels, making it suitable for all models from mini-helicopters to large-scale aircraft. 

Normal PWM output 

The 3 PWM servo channel outputs can be divided into 11 groups for output ports 1 and 2; the output sequence is freely variable within broad limits. 


S.BUS output 

Up to 18 of the new, programmable S-BUS servos or peripheral devices such as gyros, flybarless systems or speed controllers can be connected directly to this output. 

• One feed cable for all channels. 

• No cable "spaghetti", and reduced weight. 

• Additional standard servos can be connected to receivers using S.BUS PWM adapters.

. Outputs can be switched to S.BUS and / or S.BUS2 protocol. It could not be simpler.


High Response

Switchable output frame rate for the digital servo control signals - 6.3 ms instead of 16 ms - resulting in even faster response.


Aerial diversity 

The dual-aerial diversity system constantly checks the signal quality at both aerial inputs, and switches to the stronger input signal virtually instantaneously, without any transition delay. 



Devices or sensors can be connected via the S.BUS2 socket, and up to 32 telemetry data sets can be transmitted. The receiver's integral transmitter sends the telemetry data present at the S.BUS2 socket to the FASSTest® transmitter, where the data are displayed on-screen, spoken, or generated in audible form. 

Alternatively, the data can be transmitted to a separate Telemetry-Box. 


External voltage monitoring

When the receiver is connected, data are automatically transmitted to the ground by radio. The data include receiver battery voltage, external voltage (max. 70 V DC) and aerial signal strength, i.e. the essential telemetry information. If an external voltage (flight battery) is to be monitored, output port 2 is switched from servo operation to voltage measurement. The optional "Extra Voltage" lead (No. F1001100) is used to complete the connection.



Broad voltage range of 3.7…7.4 V nominal voltage. 

Note: if a 7.4 V LiPo battery is used to power the receiving system, all the connected servos must also be compatible with the high voltage. The receiver does not feature an internal servo voltage limiter for the HV servo voltage.

Recommended accessory: 

F1001100 "Extra Voltage" connecting lead with fuse.
