My Takuma efoil loses the bluetooth connection every time water washes over the board. I’ve tried a new “ESC” with an antenna. I tried adding an external antenna to the ESC antenna. I tried a new remote. Nothing keeps the connection reliable. When it gets wet you have to hold the remote on the surface of the board in the vicinity of the ESC to get it to connect.
I think it must be the One. I’ve had it for several years and never really managed to get good use from it due the disconnect issue. I bought two others from other brands, and they are great, but I haven’t given up on trying to get the Takuma to work. They cooperated for a while and sent a replacement ESC with an antenna and a replacement remote, but it sure felt like I was the only one. In fact, that is why I’ve posted here, to see if anybody else has had the problem.
On your remote display, is your board “thunder” blinking like it’s connecting and disconnecting all the time or it goes totally black after water goes over your board?
I have similar problem with my old takuma and managed to find problem in physical connectors between esc and battery and esc and motor. Give those connectors good clean, especially small pins in battery. Those small female pins in battery could get lose over time, so try to use some thin tweezers and push those metal sides together so they would make better contact with male pins. Hope this will help
Interesting. Why would the bluetooth connection drop if the ESC loses the connection to the motor? I guess I could understand why the bluetooth connection would drop if the ESC loses connection to the battery. I will investigate this. Thank you.
However, the problem is that the range seems to go from 10 feet to 1 inch when the board gets wet. You can get the bluetooth to reconnect if you hold the remote on the surface of the board in this condition, but you can’t really stand-up.
The range when the board is dry is about 10 feet. After you crash, or if a beginner is on the board and getting it wet, the range drops to 1 inch. You literally need to press the remote on the surface of the board above the ESC.
Hm that’s strange. I either have connection, or don’t (thunder on remote display blinking)
I managed to fix it with good connector cleanup, but it would come back sometimes. Never had problem with distance in connection with remote.
You ask why connection from esc to motor? Well I don’t get it either, but sometimes board wouldn’t want to turn on (it would turn on and then quickly off) when motor connectors didn’t have good connections (or they were shorted somewhere so esc decided to protect itself)
Tbh those Takuma v1 boards are really not good.
Is you enclosure always full of water too?
Yes, my enclosure fills with water. There are two (factory) holes in the bottom. I assume that is so that it can drain. It does seem incongruous with the fact that there is a seal around the hatch.
I have a Carver 2 and am having the same problem. It only started today, on my 4th use of the efoil. I will check the connectors and hopefully it won’t happen next time. Cheers, Ken
I had the same issue with my Carver 2. It was an easy fix. Replace the antenna. This may seem obvious (to me, now it does) but the little ball on the end of the antenna is very important since it insulates the core from the shield. I purchased a spare from the defunct Australian distributor.
Hi all,
I have a Takuma Carver V1 and it was working great for a couple of years.
Unfortunately after the winter break the bluetooth connection between controller and board is not working anymore, i.e. the remote shows no connection (crossed-out symbol in the upper right hand corner of the display). Everything else seems normal.
I have tried pairing of course, charging the battery and remote fully etc etc. Nothing helps.
Would be grateful for any ideas what to do!!
Since the remote looks normal I am guessing that the problem is the bluetooth module in the board/ESC? Any ideas how to get to it or what the problem there could be?
I can only talk to the V2 with smaller ESC. The bluetooth module is a separate board attached to the ESC. It seems proprietary. I recently gave up on trying to fix mine and purchased a New Flipsky remote (on sale for $83). I piggybacked the Flipsky receiver onto the OEM receiver and wallah it is working).
I now have a remote with a trigger that in not an on/off button but rather a proportional control. Also $500 cheaper. Let me know if you need help.
Does the Flipsky remote need any modifications? Can you show how you have connected the Flipsky receiver to the Takuma receiver pcb? Much appreciated. Thanks.
