As mentioned above, just wondering if this is possible on my set up as I think my remote receiver is broken / not working. Pictures attached to show what im working with. Thanks
What are you trying to test? Does the remote pair?
It might be possible to use an maytech or flipsky receiver and remote to replace the whole receiver board.
Thanks for your reply. This is my other post about the broken efoil I was given -
I wanted to try a servo tester just to make sure that the ESC and motor are working.
The main issue I have is that the remote is not connecting and its a brand new remote. I have not seen the board working at all though as I was just given it, so wanted to check the motor and ESC first before sorting the remote issue.
If I was to try the servo tester, I think that I need to connect this to the wire that is currently connected on the right side of the circuit board in the last picture above. The one that says PGND, PVCC, POUT. Does this sound about right?
Would the maytech / flipsky receiver and remote be an easy install? Any idea of price of these units? Thanks again
Hello, I tested many time my ESC ( not VESC ) with servo tester in impulse generation mode.
It is OK.
I’m not sure about the servo tester, but It looks like the receiver board takes the full voltage from the main pack and drops it’s down to 5V. I would be checking to make sure there is 5V on the receiver board as a first step and then go from there.
You mean check that the receiver is actually getting the 5v? I believe the 5v must be working as a red LED lights up on the receiver when turned on? Not sure if this is the right way of thinking though.

Great. Would I connect the servo tester to the PGND, PVCC, POUT cable that is currently connected to the receiver? I’ll test that there is 5v from the multimeter.
Also, I dont suppose anyone knows what the cable in the first photo top left might be for? Its just sitting there unplugged from factory. Has black red white and yellow wire and seems to be coming directly out of the ESC. The other small wire in that photo connects back to the PGND, PVCC, POUT cable on the receiver.
I tried connecting the servo tester to the setup but cant get it to work for some reason. For this kind of system, does anyone have any idea where to connect the servo tester on the pics above? Thanks
Hello
I have quite the same problem than you, I just buy a cruising 1 in special deal and TAKUMA just close in Europe. I have to try to do by myself.
How did you solve the esc problem? Thanks for you help …
this is my post with all the details:
Hello Alberto,
I was able to get both the first Takuma board, as well as the second board with the Omnispecial EFoil2 ESC (Takuma mini ESC), working again with a Maytech/Flipsky remote. It’s actually quite simple and doesn’t require any special tools. As @Strongarm mentioned earlier, the receiver PCB is powered directly by the battery voltage from the main supply line and acts as a buck converter providing 12V and 5V… The ESC itself doesn’t have a BEC, which is why the initial test from @inappropriatetotal didn’t work with the servo tester (no 5V).
Before you install the new receiver, make sure that the ESC and the receiver are at the same potential (a voltmeter is sufficient for this). Now, grab into the PWM GND and PWM VCC from the Takuma PCB and connect them along with the black and red wires of the PWM line (not the two battery voltage wires) to the Maytech receiver. This will power the receiver and allow you to pair the remote.
To stop the ESC from beeping and you need to provide a PWM signal, therefore you need to disconnect the yellow PWM out cable coming from the ESC to the Takuma Reciever and connect it only to the Maytech receiver. If you want to keep an eye on the battery status, it would be helpful to connect that to the receiver as well.
Let me know if you have any questions or need further assistance!
