I think as the remote needs resetting it’s likely to be a problem with the receiver. Typically the flier esc’s run for a few seconds after loosing signal from the receiver so I’m guessing every time the motor starts it’s killing the receiver somehow. Then the ESC shuts the motor down a few seconds later.
If this is the case then a small 48v? to 5v circuit on the main battery outputs to power the radio may solve it.
Is difficult to see how you’ve wired it all up as there are a few smaller wires disappearing into the battery block.
But testing with a separate power source first would confirm.
The receiver is already powered by the main battery through a step down converter. The flier 400a itself doesn’t provide power to the receiver. Edit: and the receiver is always on (LED light) and the remote stays connected with it… But the signal doesn’t go through have one attempt.
I will try to have the ESC learn the throttle. If not, you are suggesting that I should enter the data manually in the program?
Yes , you would have automatic and a couple of preset values to try , if it is that problem
I had the same problem after trying to re calibrate the throttle on the beach…
not sure what went wrong. As I had no computer with me to re-program it, I kept trying to re calibrate by holding the throttle to the max, then powering the ESC, wait for the long beep, then release the throttle and hope for the best. After a couple tries, it went back to working good. I’m not 100% sure, but i think the normal procedure calls for holding reverse to the max, which we don’t use, but that might confuse the ESC.
Also, to help troubleshooting, you can try unplugging everything else and use a USB powerbank and a cutoff USB cable to power your receiver.
Alright so I tried on automatic with the throttle at the max position then the motor started spinning like crazy and I was able to play with it up and down but then when I stopped and try to restart …it wouldn’t… Then I tried preset at 15 and 30% and I was able to start from 0 throttle to the max and play with it but as soon as I let go of the throttle… it doesn’t start again unless I power off the remote and power it on again. So now I can have the motor run as long as I want until I let go of the throttle… I feel like the ESC is preventing signal from my remote after one try! The remote is still paired with the receiver but nothing happens unless I pair it again. I will try a couple more things but let me know how I could fix this
if you can put your hands on a second remote, it would be worth checking…
I might do that! I just tried putting the reverse mode back on even though my remote doesn’t have a reverse mode and the motor started spinning continuously without me being able to stop it even by turning off the remote… I had to disconnect the power to the ESC so for those who are testing their new efoil on the water, make sure that the program on your ESC is adequate for your remote!
i guess the esc doesn’t find the end point of the middle since the remonte has not reserve mode, the esc “thinks” maybe you are in reverse when you let go the trigger (?)
try to set the first end point manualy like 1.2ms or more or less …
Yeah this was my thought about the reverse mode. So I set the forward set point to fixed 1.7m/s which is the lowest there is and it doesn’t do anything different. The motor spins well for the first throttle attempt then nothing goes.
sorry i meant move the reverse point : try 1.0ms and 1.3ms
the other value 1.7ms-2.0ms is for full trigger so it hits max rpm
Would that matter since I turned off the reverse mode?
i don’t really know, i had the same problem this orther way with one esc, remonte had reverse, esc not… this is a reason why i choose vesc so you can see and set the value you need
usually:
1.0ms full reverse
1.5ms center
2.0ms full forward
since your remote doesn’t have reverse, the trigger at rest isn’t probably at 1.5ms
you can play with setting 1.0 -1.3 and 1.7-2.0ms to try to center if that the problem, or try settings with the reverse actived to see if the motor is always spinning, good luck, i know how it can be frustating
My ESC seems to understand how the throttle on my remote is… After I power on the remote, I can spin the motor at low or high speed by playing with the throttle so this works great. The problem is that once I release the throttle fully and try to spin the motor again… Nothing! I need to power off the remote then power it on again then I get another try… But once I release the throttle fully and try to reaccelerate… Nothing again! So I’m not sure if the remote is the problem or maybe my ESC is still not programmed right!
hard to tell because you have a delay apply by the esc before reversing, i don’t know if it never sees the center line between forward and reverse it doesn’t shut itself…
this can take forever, best to try with another “classic” remote
Only some ideas: The ESC works if you move your throttle gentle, so only low current is possible. Where is the remote controls power supply coming from? Nearby ESCs Capacitors or more at the battery? I suspect the switching noise and overvoltage halting or resetting the receiver while the motor brakes.
I see the setting PWR Limit is OFF for both forward and reverse and the Delay Time is a quarter second. Is there no voltage limit? Do you use a Solid State Relay? What happens if the batteries are only half full?

magnet on the wire for the recever
another power supply for recever
This is my current set up. I do not use a solid state relay. The power limit is off so I can have access to the full power of my battery pack not just 75%. As the battery drains, the power available will be less but that’s ok. I’m also using a smart BMS for charging and discharging. Excuse my ignorance but could you elaborate more on what I could do to fix this problem? I am now able to normally use the remote and make the motor spin at any speed I want but if I let go of the throttle and try again… nothing! I need to restart the remote to get another single attempt etc…
The problem must be the remote… Is it an arduino remote?
