Q5: What are the compatible receivers to AT9S?

A: The standard packed receiver with AT10II is R9DS, which is a 10-channel receiver that supports SBUS and PWM signals synchronously with 2.4G DSSS&FHSS spread spectrum technology.

Besides R9DS, there are also other receivers with different channel quantities available.

R6DS- 6 channels(PWM signal output); 10 channels (SBUS/PPM signal output)

R12DS- 12 channels  (PWM and SBUS&PWM signal output)

Mini receivers: R6DSM- 10 channels (SBUS/PPM signal output)

R12DSM- 12 channels (SBUS/PPM signal output)


The default channel quantity of AT9S is 10 to work with the standard packed receiver R9DS. When working with the 12-channel  receivers (R12DSM,R12DS), the channel quantity of AT10II should be changed as 12
