XLX2 Question

[racer504]

Does the auxiliary wire from the esc need to be connected to the rceiver(if you're not using aux functions) for normal operations? I know it doesn't on the X8 but thought I'd ask before I messed something up. TIA!

Aux wire is the same for all, check the instructions that come with the ESC or from castles site.

Yes. Second page on the hydra quick start guide.

Nope

Thanks for your replies. Mike

What if you are running twin XLX2's? (it will be my first twin)
Do BOTH aux wires need to be attached?
Can I use a Y splitter, like on the throttle?
is a separate BEC necessary / recommended?

I would like to know the answer to this one too. I am also building my first twin. Running two X8s

I find that connecting the aux wire to the 3rd channel input makes the startup with a new setup a lot less of a PITA. Once everything works, the ESC will usually run with the 3rd wire not connected. I have no idea if a Y splitter would work. Do you need the 3rd wire included in the splitter? I can test it.

Quite easy to call or email Castle. If auxiliary wire isn't needed for a single, why would it be for twin applications?

Shot an email to Castle this morning. Waiting to hear back.
The instructions are very clear that you need to connect the aux cable, using it or not.
Only makes sense that in a twin you would have to connect both ("Y" cable).
I will post here when I hear from Castle.

From x8s faq, should be relevant to all:

6. What is the auxiliary wire and do I need to hook it up to my receiver?
By default the auxiliary wire is disabled and does nothing. If you are not utilizing this function you can leave the auxiliary wire (white wire) disconnected from the receiver. The auxiliary wire gives you the ability to adjust 1 of 7 ESC settings from your transmitter, via an auxiliary channel and dial/toggle switch, while you are operating the vehicle. To use this function you must program the auxiliary wire to one of the 7 available setting on the Castle Link; it is located on the ?Advanced? tab. The 7 selectable settings are:

None (Default) - AUX wire does not affect controller parameters.
Max Throttle Adjustment - The controller's max power is controlled by the AUX wire signal. The power is scaled from 10% at 1.1ms signal received on the AUX wire to 100% at 1.9ms. If the AUX wire becomes disconnected, the controller will use the max forward power set in Castle Link.
Max Reverse Adjustment - The controller's max reverse power is controlled by the AUX wire signal. The reverse power is scaled from 10% at 1.1ms signal received on the AUX wire to 100% at 1.9ms. If the AUX wire becomes disconnected, the controller will use the max reverse power set in Castle Link.
Max Brake Adjustment - The controller's max brake is controlled by the AUX wire signal. The brake strength is scaled from 10% at 1.1ms signal received on the AUX wire to 100% at 1.9ms. If the AUX wire becomes disconnected, the controller will use the brake strength set in Castle Link.
Drag Brake Adjustment - The controller's drag brake is controlled by the AUX wire signal. The drag brake is scaled from 0% at 1.1ms signal received on the AUX wire to 100% at 1.9ms. If the AUX wire becomes disconnected, the controller will use the drag brake value set in Castle Link.
Reverse Enable/Disable - Reversing is disabled when the AUX wire receives a signal above 50% (>1.5ms). When the controller receives an AUX wire signal below 50% or the cable becomes disconnected, reverse capability is enabled.
Torque Control Adjustment - The controller's torque limit is controlled by the AUX wire signal. The torque control is scaled from 0.1 at 1.1ms signal received on the AUX wire to 5.0 at 1.9ms. Torque control is disabled when the input exceeds 1.9ms. If the AUX wire becomes disconnected, the controller will use the torque limit set in Castle Link.
Idle Datalog Erase (Auxiliary Wire) - The controller will clear its data log when the AUX wire signal quickly alternates between greater and less than 50% (1.5ms) for a few seconds. This will only occur while the controller is idling
