10CH Essential Instructions R1.2 

 

2022/11/05 

Given an eight or more-channel transmitter, even with Always-ON active Stabilization can still be turned down 
to a negligible level by setting CH8 (Master Gain) to -100% (but for zero gain CH8 must be at -150%).

5

  

To set Stabilization Always-ON, proceed as follows: 

1.

 

Make sure the receiver is programmed to one of the five options listed above (page 5). 

2.

 

With Transmitter ON and receiver bound, power receiver ON and 

wait at least 60 seconds

3.

 

Press and hold Button F until the blue Setup light turns ON. Release button. 

4.

 

The green Status light should now also be ON to indicate that stabilization is active. 

To cancel Always ON, repeat. Hold Button F until the blue Setup light and the green Status light turn OFF. 

Step 5: Using Stabilization 

 if activated. 

The following assumes that you are using a Generation 2 or later Spektrum transmitter and that you have 
already programmed the receiver with one of the stabilization options explained above. Using the receiver with 
other transmitters is discussed in a separate pending document

It is usually most convenient to complete receiver programming (see Step 4, above) and items 1 to 3 below 
before mounting the receiver in the plane.  

1. Set up the transmitter  

Set up a new model definition in the transmitter or reset an existing model. In particular, disable any delta wing 
(elevon) or V-tail mixing in the transmitter 

 if these mixes are required when stabilization is active, they must 

be done in the receiver. Make sure servo Travel (end points/limits) is set to 100%. 

Set up a switch on channel 7 (or optionally on channel 5) to control Stabilization ON/OFF. 

Set up channel 8 (if available on your transmitter) to be controlled by a knob or slider for Master Gain. 

2. Bind the receiver 

Bind the receiver to the transmitter, as explained above (Step 2). 

3. Test the receiver  

Power up the transmitter then the receiver

The red Status LED should be ON. 

Check that the Stabilization ON/OFF switch works correctly.

6

 

Temporarily plug a servo into each of the Ail, Ele, and Rud outputs and check that they operate normally in 
response to the correct transmitter sticks. Power OFF. 

4. Mount the receiver in the plane  

The receiver can be mounted upright or inverted and must be aligned with the direction of flight. Either set of 
servo connectors can be at the front.  

The receiver will not work properly if mounted across the fuselage, on edge, tilted forward or backward, or at an 
angle to the centre line. This receiver, unlike some other stabilizers, does not need to be mounted particularly 
close to the centre of gravity of the model.  

 

5

 Even with stabilization turned down to zero gain, Delta Wing or V-Tail mixing must NOT be done in the transmitter. 

6

 The green Status light on the receiver will be OFF if channel 7 is at 0% or 100%. If channel 7 is at -100%, It will be ON, 

indicating that stabilization is active. The same applies if channel 5 is used for stabilization ON/OFF.
