From my own experience I’m tempted to agree… will probably never touch them again.
Very interested in the neoBOX development. I think Torque Boards are also developing their own.
Guys, I need your help on this…
Flipsky engineers said this is normal behavior and is working as designed.
As I show in the first video (https://youtu.be/MFuzuoao1hI), it doesn’t happen at all with an ESC from diyeboard.com. However, because I don’t have other VESC variants to compare besides the FSVESC, could you give some feedback whether you also experience this difference between the two motors when not loaded?
Here is the response from Flipsky technical team:
They has explain is normal, as below:
1.Because this is no-load,and the load is very light, and the frictional forces on the structure are different. When the same output of low power is caused, one side moves and the other side has not moved. This is a multi-faceted problem, there is normal .
2.ESC output power control also has a small deviation.
3.When the person stands up, under load, these deviations and small frictional differences can be ignored, and balance can be achieved.
Call them out on their bullshit. Tell them they have a slave CAN communication issue. I had to make a video to prove it was junk. Then had to pay to send it back. Record you turning on the board hit throttle and both wheels spin, go ride or whatever and keep filming. When you feel one side stop working, flip the board over and spin up the wheels showing only one spinning

Actually I just show that in the video 
Also on the other video I show it working flawlessly with other ESC…

Sounds like you need to be more stern with your wording. Tell them you are going to file a chargeback due to defective products

Hi, I’ve similar problem with my Flipsky 6.6 plus, when I’m trying to configure with mobile app I’m getting notification about firmware doesn’t mach, and when using VESC tool application for PC sometimes it cant read information from motors.
