I’m sorry to hear that You are having issues with your Flipsky Dual 6.6. I
My first thought is that if you plug in the USB Cable in to the Slave side and connect to the VESC Tool Program successfully, then there is probably a “Setting” somewhere that says something like: “How many minutes of inactivity should the ESC wait until it shuts down”. Basically, the ESC will automatically turn off the Flipsky ESC after a certain length of time.
I am guessing that maybe you need to set the “How many minutes of inactivity should the ESC wait until it shuts down” for both the Master Side and then again on the Slave Side.
For example, this setting might currently be 10 minutes on the Master side and only 2 minutes on the Slave side.
Now with regard to supporting Flipsky, I basically asked Paypal to get a refund for me. They have a great looking product with great specifications for Power capabilities, but I could not get the ESC through programming without irreversible hardware damage
So check this out: I originally started pursuing the Flipsky Dual 6.6 Plus ESC because the FOCBOX Unity ESC was on Back Order at the time when I ordered it, whereas the Flipsky unit was available to ship right away.
I observed that the Power and Motor Wires on the Flipsky 6.6 were bigger than the FOCBOX Unity ESC. I figured that this meant the Flipsky 6.6 Dual ESC unit was designed to handle greater Electrical Power throughput as the specifications seem to suggest.
So in the middle of my trials and tribulations with the Flipsky ESC, the FOCBOX Unity Dual ESC finally shows up. I put it in and it worked perfectly. I have put about 75 miles on it and I can say that it has plenty of capacity to handle my system which includes 12S6P Sony VTC5A Batteries and Raptor Enertion 2.1 Hub Motor Wheels.
It is so important to be able to rely on your ESC when you are in potentially dangerous riding conditions. I am now definitely a fan of the FOCBOX Unity ESC and would highly recommend that You try the FOCBOX Unity ESC next time instead.
The FOCBOX Unity ESC has a simplified Cell Phone App for programming which tells me that someone became intimately familiar with the firmware and hardware of the FOCBOX Unity ESC to be able to write such a simple first try home run App form it. With the Flipsky, You need to use the General Vesc Tool which I am sure is a great tool, but I couldn’t get through the programming because certain windows that are supposed to pop open at certain times when going through the wizard didn’t pop up. Then, you take your best guess at what to do next and its 1 click and your done with irreversible hardware damage. This is Flipsky’s new product so maybe they are just working out the bugs.
Anyway, the real renaissance of riding FOCBOX for me came after doing a little adjustment of the “Input’s Advanced Configurations”. Basically, you can tell the ESC how much time to use when making the adjustment to the power output to the motor wheels based on changes in the joystick position. So if the power is jerking you to hard when you push the joystick forward, just make it take longer to manifast the change on the output side until it is sufficiently smooooth… riding… Baby… WHOOOO YEEAAAHH!!!
You can also implement functions on the Input so that when the joystick is closer to the zero position, say from zero to 30 percent of the joysticks forward range, then the output changes at a lesser rate than 1 to 1 with the input.
SO like at 10% Joystick your at like 3% Output, then at 20% input you are at like 9% output, and at 50% input your like 35% output, and at 60% input your at 50% output, then by like 80% input your at 75% output, and at 90% input your at 90% output.
This is kind of hard to follow and these numbers aren’t exact, but you can see a graph that shows the entire range of input percentages and corresponding output percentages and you can drag the curve up or down to vary it. You can also apply Polynomial, Exponential, etc function characteristics.
For me, this was the key because at first, I would just be touching the joystick the littlest amount and the board would fly out from under me. But by adjusting the acceleration time to take longer, and by making it require more joystick movement when the throttle is close to zero, my board is like a 600 cubic inch Cadillac with some 4.56 gears Man. You hop on and push the throttle forward a reasonable amount and the acceleration comes up nice and easy, but after you get past about 50% throttle, it starts tomove back towards a 1 to 1 correspondance between the input % and output % which is sweet because the second half of the throttle range has some scary speed. I’m not sure i’ll ever go past 75% throttle unless i’m wearing a wingsuit!
And also, until you get it adjusted just right, beware of over throttle. This is when you push the joystick like all the way forward when your just starting to roll at like 1 mile per hour. This can cause something like a stall to occur. I’m not sure exactly why this happens, but it doesn’t happen anymore now that I made my adjustments to the input to output correspondence. But just remember to apply the throttle gradually.
Anyway, the moral of the story is that I would strongly recommend trying one of the latest and greatest FOCBOX Unity ESC’s and then programming it via Bluetooth using the Cell Phone App. then, do a little adjustment in the "Advanced Throttle configuration " menu and life will be GOOD!
