VESC Cutting Flipsky 75200

Build, Repair & Mod
21

Hi,
Maybe this info helps someone.

I have recently built an efoil with Flipsky 65161, 75200 ESC foil and foil board set from Gong for winging. First run I had a lot off cutoffs, before cutoff remote control screen showed ~100A and ~5000W. It was more like jetboard :sweat_smile:

My problem was a duck around proppeler. Before second atemt I have removed it and efoil changed like day and night. Without duct I need max 60A to get on foil, if I give more power itā€™s almost impossible to keep nose down.

P.S. I have also limitted power to 5000W with VESC profile.

The consistent feel across the whole voltage range is the advantage. Also every commercial product does this.

I donā€™t use a duck I read that it limits performance and range a lot but I didnā€™t know it was that bad. Thanks for sharing.

Although the idea of a smoothing of the available ā€œpowerā€ sounds appealing Iā€™m not sure I want to give up the top end that the rig is capable of. Iā€™m not likely to try to foil at 40+kmh but itā€™s nice to know that capability is there if I need it.

My current settings are providing the quality of ride that Iā€™m after, this discussion however has prompted me to look at some of the other parameters to ensure they align better with my actual hardware as opposed to whatever the medium inrunner wizard came up with or that are ā€œstandardā€ in vesctools.

Thanks to you, @Larsb, @ludwig_bre and @sat_be for expanding my knowledge of this. :grinning:

I just got my Flipsky 75200 set up and encountered the same problem with the power cutting outā€¦

Gonna go try these new fix ideas ā€¦

Thanks for asking the question and thanks everybody fkr your replies!

What helped us was setting the sensor mode to HFI (general > set sensor mode hfi) and setting HFI to
HFI Samples: 16
HFI Start Voltage: 40,0 V
HFI Run Voltage: 25,0 V
HFI Max Voltage: 25,0 V
Sensorless ERPM HFI: 1000,00
HFI Start Sample: 65

You will need to change the voltage accordingly to your specific setting.

I implemented a lot of the suggestions I got here. I changed many settings so I canā€™t say for sure what was the good one but I suspect it was the setting for total watts I had it too low it was a 1500 watts so the motor was cutting The motor is rated 6000 watts so you want to go to 6000 or higher. I put some setting higher than rated but the motor never uses more than 150 Amps when I start from a standstill. I run a 10S setup so 150A at 40V is 6000 watts so thatā€™s ok and itā€™s only for a few seconds once you gain speed the power goes much lower. I rode my efoil all summer so donā€™t despair itā€™s a good combo you just need to find the right settings.
