āĀ The RPM limit also has a soft back-off strategy.Ā
āĀ Commutation works perfectly even when the speed of the motor changes.Ā This is due to the fact that the magnetic flux is integrated after the zero crossing instead of adding a delay based on the previous speed.
āĀ When the motor is rotating while the controller is off, the commutations and theĀ direction are tracked. The duty-cycle to get the same speed is also calculated. This is to get a smooth start when the motor is already spinning

Ā Changes:
1. Power advantage
In order to effectively and safely protect the power contact from oxidation caused by electric spark burn and the electronic components of integrated circuits from breakdown and to prevent the occurrence of an electric spark which may cause explosion, we added an anti-spark switch to the front of the power supply to allow a maximum current to pass up to 300A. Also, itās more convenient to use.
In order to make the power supply filter better and the voltage more stable, we replaced the original C46 and C47 with large electrolytic capacitors with larger capacity and better energy storage. Meanwhile, C37 ,C39 ,C41,C40,C43,C44 were all replaced by 10uF 100V with High voltage capacitors. In this way, the voltage change of the MOS becomes more stable and efficient.
2. Processing Advantages of GND on the Circuit
In order to better handle the large current GND and the mutual interference between the GND of the MCU circuit and the GND of the NRF circuit, we added three O ohm resistors to better achieve the filtering effect.
3. Output optimization of Power Supply 3.3V
Replaced the LM3671 chip with the two-channel MIC5219-3.3YM5, upgrading from the original 3.3V, 600MA to 500MA*2=1A output, better supply power to peripherals, meanwhile, adding two IN5819 diode rectifiers to achieve 3.3V for short-circuit protection, replace the C9 2.2uF on the capacitor with 10uF and add a 4.7uF filter capacitor.
4. Output optimization of Power Supply 5V
Replacing capacitor C31 2.2uF with 22uF
5. Other optimization
Replacing capacitor C15 2.2uF with 22uF
6. Optimization of Mosfet
12 Power MOSFETs NTMFS5C628NL is specially processed on heat dissipation and over-current to achieve continuous 60A output and more stable performance.
7. Optimization of PCB layout and process
1). The PCB adopts a gold-thickening process with a 6-layer PCB layout design. The thickness of each layer of copper foil is 3OZ, and the total copper foil thickness is 3OZ*6=18OZ. meanwhile, the PCB increases heat dissipation and the over-current treatment process at key part--sunken sunroof, making the overall effect better and having more advantages!

This is my review of the FlipSky Dual FSESC4.20 100A. This dual ESC is the same price as many other single VESC’s, it's definitely a value. I am so surprised at how well this ESC performed. Your not going to build a racing board with it, but for a mid-range ESC it performs above average.

Hello, Grace
Just a little update about the FSESC, they're doing great!! Here is the current temporary setup to test the two motors and temperatures:Of course the lectronics will go in a proper enclosure once I have done all the tests!This is also interesting, I have a thermal camera, and as you can see in the following image, The ESC's remain properly cool (about 35°C after a 13km ride!)The motors get about 45°C warm, and the black motor left side, gets a bit warmer due to more limited airflow than the red one.There is also a warm spot on my left tire, due to the belt rubbing against it, very interesting!

“Hi Gemma, it's very good. Easy set up and install. I'm using a friction drive N5065 motor on my mountain bike. Tested it at 12volts and got 22kph, then tested at 29volts and got 39kph now I'm waiting for another battery and will test it at 42volts and hoping to hit that 50kph mark. Will most likely push it to 54 volts in the near future to see just how much it can handle. Is there somewhere I can leave a review to help you guys as I'm very happy with the controller so far “
- From Australia customer
"i bought this for my vesc and fts right in, product is well finished and it comes with thermal paste already applied at the places where the mosfets are. It gives the vesc a good protection and the ability to directly mount it wherever you want to. I plan to mount it on a copper plate which will then lead out of the enclosure to some cooling fins. For the money great value."

"The finish is really good. There are many small details like seals; a trap to gain access to the connectors, which also has a specific seal; just like on motor connectors.
I have not tried yet level finish is really good at all, even surprising enough. We are clearly on a product reflected in its entirety."

"FlipSky happen to be the ones we’ve found most willing to assist and they seem willing to incorporate suggestions / feedback and take real world data and use it to make the product better. We don’t ultimately care who does it, but if FlipSky ends up being the ones to bring bullet proof ESCs to the world with VESC lineage then we certainly won’t be complaining and we’re doing what we can to help. We just need reliable product at a reasonable price. Right now, it’s not.
disclosure: We are looking at FlipSky as a potential supplier. We have not made a decision yet but hope their ESC can meet our requirements. The no.1 issue for us currently is reliability … it cannot fail and you don’t have to look far through these forums to find them still failing. We are trying to get their ESC to work in our product/s and hope that it can be sorted in time for us to use it. Our feedback and testing is also looping back into the project through FlipSky. We’ve found them to be responsive and willing to undertake continuous improvement.
