Propeller Turns (or Stops) Intermittently Without Remote Action

Hello, I have an issue with my efoil. It no longer responds to the remote control. Initially, I thought the remote was faulty, so I bought a new one, but after reconfiguring it via VESC Tool, I encountered the same issue. I’m wondering if the problem might be with the receiver. Sometimes, when I press the trigger, nothing happens, and other times, the propeller spins on its own.

I noticed that the very first time I reconfigured the remote in the software, the blue PPM mapping bars were unstable, unlike in the tutorial video. It still worked for a while despite that. However, the problem has worsened, with greater instability in the bars, which affects the motor’s operation. I’m not sure if my explanation is clear, so I’ll include a video link that shows the issue more clearly. Thank you in advance for your help. https://youtu.be/2WhdRVtNJvk

nobody have an idea of my issue? Please try to give an advice, i don’t have idea how to fix?

What remote?

What vesc?

How is it connected?

Ever got wet?

Does it happen out of the water

Using UART or PPM

Are you getting data back to the remote?

Hi than you very much for your answer.

remote is: MTSKR1905WF (new)
Receiver: MTSRR1905 Receiver (old)
VESC is: VESC 75200 MAkerbase (new)
motor: Motor flipsky 65161 120Kv (new)
IT’s connected with Bluetooth I think I used the normal way to connect it (like in Maytech video)
Never been wet but I changed the VESC for a new one last year (but never been ride after changed)
UART or PPM (i’m not sure but i believe PPM ) , actually i followed Ludwig video about VESC to setup everything:https://www.youtube.com/watch?v=QaVPISP8BF4&t=1086s

And It worked well until the remote setup as you can see on my previous youtube link, the blue bar doesn’t stabilize and run the motor.

“Are you getting data back to the remote?” , i don’t know what do you mean exactly, sorry i’m a bit noob. :sweat_smile:

Hi mate have you had salt water anywhere near the reciever or in the board. When you are getting random things happening especially the motor turning on and off usually means bad connections between the reciever and esc. Replace the reciever and corrosion x all your connections.

Hi,yes I always have water there and the receiver is the last thing that I haven’t changed.
I gonna to change it thanks , i hope it will fix.

Thanks
