Hooking up twins

[dasboata]

Hi on the parallel connector going from the ESC?s to the RX do I need to disconnect the red wire. Both Motors are cutting out ,, under load but not on the bench ??? Im pretty sure I have all the programming right thanks

Assuming you're using a Y-harness (both ESCs plugged into the two 'top' connectors, and the single 'bottom' connector plugged into the Rx)...on the Y-harness, cut one of the red wires. This will allow the BEC power of one of the ESCs to reach the Rx, while preventing the other ESC's BEC power from reaching the Rx.

Chris, what ESC's are you using? If they're an OPTO model and do not have BEC's in them, no need to cut or de-pin any wires. As Panther mentioned, if they have a BEC in them, you only need to cut or de-pin the red wire on one of the two Y-harness legs.

Receiver setup aside, cutting out under load could be a sensitive LVC circuit in the ESC. Since i time my runs, I disable the LVC whenever possible, or set it to the lowest voltage if it can't be disabled.

Do you think this is why the motors could cut out assuming I have the ESC programmed correctly ? my ESC's are water cooled converted XLX they do have a Bec circuit adjustment I have it set to 6V thanks Guys !!

When does it cut out? In the water under large load?

On the XLX 2 castle esc you must remove both red wires from the Esc to the reciever to run a reciever pack. If you are not installing the red, white and black lead in the third or fourth channel of he reciver it will glitch when ran. If you do not remove both lead rec wires and hook up the reciever pack it will short out the system and destroy the esc. also you need a 4 channel reciever for twins and all the leads from esc to reciever.

Perhaps we have different definitions of twins, but it the common scenario of two motors, two ESC's, single throttle, you only need a 2ch receiver as both ESC's can be wired with an appropriate Y harness.

On most appclations you are correct. I am taking about the XLX2 onlyIMG_2452[1].jpg

not running a RX pack Randy ,,

I can't imagine the castle works any differently than any other ESC for a twin application. I believe what you're telling me though. Is it because the Castle has telemetry built in? Why must two XLX2 ESC's each be run off their own receiver channel?

why do you cut the auxiliary wire ? My ESC is a XLX and I am not running a RX pack thanks

Yes the XLX2 ESC's each be run off their own receiver channel for twins. In the case of running both twins on Bec distance becones a liminitation. I had problems with my twin it was glitching when it got far away over 600ft. I set up Opto and the problem went away.

I do not cut the red wire on either lead I remove from plug's only. In the case of needing to read the telemetry the red wire must be pluged back in and the auxiliary wire in plugged from reciever. This info we obtained from Castle tech's when I was working out the proplems with my drag boat. I just saw you were running 12S, my XLX2 is different will only run to 8S and I have never ran that one, sorry for hijacking your thread just trying to help. I burned up both esc in my boat setting up Opto and wanted to save any one $325.00 in hard lesson learned.

6s and XLX not XLX-2
