Is there any way to reassign the right slide lever(aux3) to operate aux 4 or aux 5?




The 10x uses only the first 8 channels for failsafe/hold operation.I need to use the right slide lever to operate brakes ,but I cannot tie up aux 3 for brakes.
Aux 1 is used for flaps and aux 2 is for right ail(crow). I want to put my smoke system on Aux3 (mixed to snap roll button for use and also
for visual failsafe indicator.)

If slider cannot be reassigned,then how about aux1 (flaps ) reassigned to aux 4/5?

I thought I read that aux 4/5 are not 1024 but 512 (lower resolution).This may not be a problem on flaps ,but what happens if/when failsafe occurs on aux4/5?

This is on my Kingcat and I've finally run out of channels!

Thanks ,

OK.. first up.

Aux 4 and 5 are in fact 1024 resolution, they're just sampled at 1/2 the rate of the other channels. This is why we don't recommend you use them for primary flight controls such as aileron, elevator, or rudder.

Now.. you can move the aux 4 or 5 to the slider no problem using Origin mixing. Origin mixing says to take the physical value from the trasmitter control and apply it to only to the mixed channel while ignoring the channel it's originally intended to drive.

1. Disable the right slider in Code 17 (aux 3). This tells the radio not to use the right slider for Aux 3.
2. Create a mix with Aux3 as master and your brake channel as slave
3. Press page twice and select Origin mixing. This now tells the radio to use the right slider, but only for the mixed function, and not the original function.
4. Press page again and setup the mixing values as needed for what your brake actuation.

This logically disconnects the slider from the Aux 3 channel in the transmitter allowing you to make it operate the brakes.

Now you need to setup your smoke.
1. Create another mix, this time Aux 3 to Aux 3.
2. Press page once and assign this mix to the snap button.
3. Press page twice to get back to the original screen and adjust the values to make the smoke turn on and off as you want.

That should do it. I know it's a bit confusing.. but once the light goes on you'll find origin mixing to be incredibly powerful and useful.

Doug, can you elaborate? What does this exactly mean, sampled at 1/2 the rate?

That means that the other 8 channels are updated from the TX to the RX in every single "frame" that is transmitted, whereas the Aux 4 and Aux5 are updated every second frame. (A frame is just a collection of information that is sent out by the TX at discrete intervals, and includes both information on required servo positions and data used for failsafe purposes).

If you were to put the split elevators on a Bobcat on channels Elev & Aux 4, and you gradually fed up-elevator input in, one of the elevators would move up every single time a frame was sent, whereas the other would update every 2nd frame; that would make one elevator half seem very smooth, while the other seemed a little "jerky" (though, depending on the setup, the minor discrepancy could be very hard to see). That's why JR says it's better to use these channels for something other than primary controls. I use Aux 4 and 5 for things like speedbrake and wheelbrakes - there's more than adequate response for controls like that.

Thanks for the clarification Gordon. I appreciate it.

Thanks Doug,

You explained it very well- it was easy and now makes sense!
