Failsafe is not supported for servos connected to the X-Plus 
Module. We recommend that no failsafe should be expected or 
attempted for a servo connected through the X-Plus Module. 
However, servos connected to the X-Plus Module will hold last 
command in the event of a failsafe condition.

1. Open the Frame Rate Menu in System Setup. 
2. Scrolll to X-Plus and press the scroll wheel to activate. The 

X-Plus Inputs screen is now active in the Channel Assign 
menu. 

AUX6 and AUX7 channels are available on 12-channel receivers  
when X-Plus is active. AUX6 and AUX7 are 2048 resolution and 
22ms frame rate (12-channel receivers only).

Channels X+1 and X+2 are duplicate channels of channels 11 
and 12 on a 12 channel receiver with X-Plus active.  If chan-
nels 11 and 12 require any adjustment for travel adjust, servo 
reversing, sub trim or any other function, adjust channels X+1 
and X+2.  Note that channels 11 and 12 will also show on the 
X-Plus monitor as channels X+1 and X+2. 

If you select 11ms frame rate before you activate X-Plus, the 
transmitter reverts to 22ms frame rate when X-Plus is active.

Do NOT connect throttle or any primary 

control surface to the X-Plus Module. The X-Plus chan-

nels are intended to be used for auxiliary functions only. X-Plus 
channels have a resolution of 512 and variable latency from 
22ms to about 88ms. When X-Plus is active, the fi rst 10 chan-
nels default to 22ms. 

Refer to community.spektrumrc.com for more information about 
X-Plus options.
