Guys, how do you power on your VESC ? Do you use an antispark switch button or a regular one ? I thought a spark could appear when linking Vesc to battery connectors but not when you switch on the board (am i right ?) So what would be the interest to put an antispark button ?
Good point about the remote - I do have the Maytech remote with a display so will use the uart port for that. Having trouble to figure which cable from the VESC to connect with though as there is no documentation to speak of describing what all the unmarked cables coming out of the rubber sealing is to be used for. Any tips on which cable I will have to connect to my TXD and RXD pins on the receiver?
Okay, got it working once I figured out the logic behind all the cables, thanks for the help.
This is how the setup looks, and now I can get full info through vesc in the remote controller window.
Good experiences with 13s. No problems at all, 5.5kw for about 20sec each time to get on foil. 48v 40ah pack 120kv flipsky. Very inefficient foil and prop. But just for testing the 200a vesc at 13s at max 180a battery amp

Did you ever have problems with electronics to the point where you want to set it all on fire or shoot it with your favorite firearm just to get a little satisfaction from your expenditure of hundreds of dollars…
That’s where I am right now! So fed up with the VooDoo fsesc and the tool too… Three weeks four different controllers hundreds of different settings and no joy, rpms go from zero to full power in 1/16" of throttle and only works when my PC is connected to it and that’s the best it ever got (running on the bench no load).
I’m sure the information I need is on this site somewhere, the problem is that it’s not all in one place. Bits and pieces are infused throughout this site which is good except for the time it takes to find, read, write the important bits down, search again rinse and repeat. After hours of starring at the computer screen putting it all together and reprogramming the fsesc and no joy…
As I said in the past this site needs to be organized to the point where someone can look at successful builds and duplicate the build with a list of parts (where they are available) and procedures/build tips from the original builder.
Someone on this site once said to me "that would take all the fun out of it " It’s not fun when you are reading a post and an add change scrolls away from the post your trying to read every minute or so. I have noticed that there has been 2 or 3 times the amount of adds this month… On one page I landed on there was an add between every post!
I like the fire option… The FlipSky fsesc’s soul can be released like the Vikings used to do. In this case it would be more like an exorcism LOL
There was some guys selling efoil plans on another thread you might have better luck with that. You are welcome to spend your time making detailed build plans and updates as well.
If you are in current control mode, 1/16" is probably all it needs to max out rpm. When you hold it half way you are telling it to go to 50amps or whatever you have it set to. The motor can’t get to 50amps with no load.
I do plan to have a detailed parts list, and builders guide for my board available when I get the prototype operational and any bugs cleared.
I hear what your saying about throttle response but I have watched many videos that show a fully controlled motor on a test bench and not one jumped to full throttle but were fully controllable through the entire range on the remote with no load. My latest attempt was a FlipSky VX2 pro v6 screen remote, same results so that completes the testing of remotes (all having the same result tells me it’s not the remote)
I can spin the motor up to operating speed of 4,500 rpm using the vesc tool with no problem. I’ve had it up to 9,500 using the vesc tool but on remote control it goes from zero to maximum 4,500 rpm just moving the thumb wheel off the center position. There must be a fault in the fsesc or the information I’m punching in. Also having trouble with the vesc tool recognizing any type of remote so calibration is hit or miss. To get the VX2 pro to show any kind of control I have to use the twist grip choice to get any response at all from any throttle control except for the computer and vesc tool.
I’m thinking about using a smaller vesc not connected to the motor but connected by can ports to the fsesc to control motor speed only. I wonder if anyone has tried this before.
I’m thinking that if the computer can control speed that another vesc could take the place of the computer and do the same.
Yeah it isn’t the remote. It is likely a setting on the VESC. Do you have it current control mode? What is your max motor amps? Your throttle will control between 0 amps at 0 throttle to max amps at 100% throttle. With nothing connected on a bench it is probably only 1-2 amp max before it can’t turn any faster. Change your motor amps to 5A and try again.
Or change it to duty cycle mode and try again. I’ve found that doesn’t feel as nice in the water though.
