I bought the 17.5 MMM motor and it arrived at the end of February but I've been having some problems with it. When I accelerate it kind of bogs and hesitates a bit before it gets going. I also noticed it's not any faster than my old Speed Passion motor that had no timing adjustment on it. I thought it was the sensor cable so I ordered a new one and tried that but I still got the same problem. I'm using a Reventon Pro with this motor too to replace the old Citrix ESC I was using before. So I took out the sensor board and did a bit of troubleshooting with a multimeter to test the connections and I noticed that there are two empty solder pads. It looks like a capacitor or resistor should go there but I"m not sure. Can anyone confirm if my sensor board is missing a component in the area I have circled in red?
