ok, new problem arisen,
Tried to power up the esc today and it wouldnt work, just had a green flashing light on it and the fan spinning.
had to recalibrate to get it to work, after that it worked fine until I powered down and back up again, lo and behold green flashing light again and had to recalibrate again.
It seems I have to recalibrate the esc everytime I power it up.
also noticed that the throttle dead band adjusts itself from the default 80us to 60us everytime I recalibrate which is weird.
here is a video link of the problem
