VESC Tool Help for new build

Hi Guys,

Was hoping for some help here. I just got a flipsky 75200 VESC and I was learning how to program it using the following video recommended on the site.

When I get to controller settings and attempt to progam via PPM I get nothing in the setup. Controller throttle doesn’t show when pulling the trigger.

The controller is a Flipsky VX3 remote

However when I try the nunchuck option it works, and the motor spins. It’s hard to tell if it’s working as it just goes to full throttle since I have no load on it. Any tips on if this nunchuck option is the way to go and what settings I should choose for it? Or did I do something wrong so it’s not working for PPM?

I hooked it up using the UART connector as I’m hoping to get battery life on the controller.

plugged into this port on the VESC

Have you gone through the menue on the VX3 to choose PPM as the output?

As well, I could be wrong, but I think you are using the wrong VX3 cable. The PPM cable should have three wires not four; Power, Ground and PPM.

Sorry…here should have been another cable supplied with the VX3

When only using UART, do not use the wizard.

Within VESC Tools, under App Settings > General, make sure APP to Use is set to UART.
Now go to App Settings > VESC Remote. Set the Control type to what you would like to use (I have it set to Current)

Press the arrow down A (:arrow_down:A) to write the settings to the VESC.

Thanks! Is there any way to set the power settings for UART or you just use it? I saw PPM had a whole setup process where you could configure the trigger set the 0% to 100%.

We only have UART connected and no other connectors are needed (even the extra blue wire to the battery is not needed!) to see all needed data on the remote.

Power settings are not needed as far as I know, but you could play with the Input deadband a bit for some tweaking

Thank you for the picture. I confirmed I have the same wires connected so I should be OK. appreciate it!

I use this same setup, VX3 and Flipsky 75200 on UART. I didn’t do any power settings or throttle configuration in VESCTool like seen with PPM in the video above. I do however use the power mode button on the VX3. That second button on the side of the remote cycles between L->M->H which are the 3 power modes. I think it just limits the max current/power that you get from a full trigger squeeze, no fine adjustment of the power ramp or anything. I think it always starts up in L and then I switch it to M. I found H makes it a bit too sensitive.

Hello Guys I am new here. I am Sebastian from germany and right now I have my Setup finish. I am using the Flipsky 65161 Motor and the Watercooled 75200 with the vx3 . I connected first via ppm but I want all parameters on my control so now I connected the vx3 via uart. It work but the trottle control is terrible and I dont know why. If I press trottle it is suddenly 100% trottle but the remote shows 40% Why is that what I am doing wrong?

Are you experiencing this with prop spinning in the air or in the water?

I seem to be the only here who uses ChatGpt, and found it helpful for setting up my ESC.

Out of curiosity, and so I can learn something, I entered your problem exactly as a your comment and many possibilities were raised and solutions in the response, you can try yourself or I will message you with the response.

ChatGpt “Yeah, I’ve seen that issue pop up a few times with VESC + VX3 on UART — it’s usually not the hardware, but how the remote and VESC are talking…”

The most common cause has already been hinted at.

You try it on land without resistance and have VESC set to current control.

If set up like this, the behavior is exactly as it should be and will work fine in the water.

set it to “Duty Cycle no Reverse” or “Duty Cycle Control”

Ok thank you guys i did it of course on my table and not in the water. Didnt know the behaivor is normal.
