You are using a nunchuk so you will need to use the canbus to control the second VESC. I have not tried splitting the leads on a wii dongle yet but it may work. Better to use the canbus though.
If you where using a conventional FHSS transmitter you could split the receiver output leads and control both VESC through the ppm input. Be sure to only have the red wire coming from one vesc if you do this.
This is my setup. Actually I just want to try and see what happen if I didnt do the setting as previous comment. But yeah, Iâve encountered some problem such as one of the motor suddenly stuck or pause. Maybe because I didnt put any ID or set the slave or master.
This is my dual setup picture and @chaka , that means I need to cut which wire? because im using a bit different color for the wire and got confused. Im also using 2.4ghz mini controller.
The center wire needs to be cut on just one. Leave it on your master vesc, it powers the receiver.
When @onloop says that we need to click the send status over CAN for the slave. Just to make it clear, u need to tick or no tick it? haha sorry for my bad English.
When I cut the slave, red wire, the receiver didnât get power at all. Maybe Iâm doing it the wrong way.

Leave it on your master vesc,
[/quote] 
Unless you have a ubec/sbec around. The center wire powers the receiver and the power should come from only one source.
haha i dont know about BEC/SBEC. I have 2 VESC and 2.4GHz mini controller.
and this is my BLDC setting for master and slave:
Master 1
Slave
and I am planning to make the VESC on the right my master and left is my slave VESC
What @chaka is saying is that you cut the red wire coming from one of the VESC and leave the other connected. You see, the red wire is what feeds power to the receiver. You only need the power to come from one of the VESC, it doesnât matter which VESC the power comes from but the receiver should only receive power from one of the VESCs.
Hope that helps. AlâŚ
If youâre using CAN bus in a master/slave configuration, the receiver should only be connected to the master.
First you need to make sure both VESCâs are working properly by connecting each one to the BLDC tool and using the arrow keys on your keyboard to run the motor. Once youâre sure they are both OK, you can set up CAN bus:
Hope this helps
So according to Raptor board, the dual vesc setup with non-Nyko Kama (or NunChuck) receiver should be like this?
No need to connect both vescâs receiver side? Then how to know or decide which side is master one?
Correct, If youâre using CANbus, the receiver is connected to the master only. The app for the receiver is configured only in the master. The master takes care of the control of the slave.
Thanks, that means WITH the CANbus setup, the one connected to the receiver becomes the master one?
So is that possible to do a different way on dual Vesc which like old esc setup that âwithout CANbus then connected both receiver side with the âYâ bridge then take one sideâs middle wire outâ
Learned those setup from : http://2bfly.com/knowledgebase/electronic-speed-controls/multi-engine-esc-wiring/
you have to program the master and slave in the BLDC tool software.
or you can set them up as 2 individual ESCs and use a Y if you prefer that.
Okay! So there are not big differences, are they? I mean these two setup.
If you use a Y connection You wonât have traction control but Iâm pretty sure you wont miss it. You wonât be able to get realtime data from both vescs over the same usb connection either, youâll need to plug into each vesc separately to look at realtime data. It will make config straightforward though, you can set both vescs up identically.
Very helpful info mate. Thank god Iâve asked those question. Didnât even know that before. Then now I know what setup Iâm going to run in future. Cheers!
Hello Everyone,
I heard that the VESC is open source which raises the questions.
