My build has a Flipsky Dual FSESC6.6 Plus as VESC along with a MTB kit with 8’’ Pneumatic Tires and Dual Belt-Drive 2 x 2000W 6354 Out-runner Motors.
I’m experiencing an issue where sometimes only one motor spins. I can feel it when riding and it’s also visible with the wheels spinning freely. I took a video  where one can see this happening.
Do you know what can cause this problem, could be a defect in the VESC?
