Yup, just verified version 1.20. It's not listed on Castle's MM revision document, but it's there. Must have simply applied the firmware fixed they did to the MMM...
V1.2 is a good upgrade. Runs smooth and cool for me. I actually preferred the old method of cranking up power when it needs it. Sure if you have a locked rotor or something it could be a problem but you shouldn't be holding the throttle down if you know it's messed up. IMO it was useful.
All I ever wanted was an honest weeks pay for an honest days work.
