When I received the RPM sensor and magnet/holder the "red line" on the magnet wasn't there. I couldn't even seen a red dot on the magnet. So I took a guess, to see what happened. I am getting a reading from the sensor, but i'm pretty sure my basically stock erbe can't go 127 MPH as the Traxxas Link tried to imply. I didn't see when it hit that mark, just that is what the top speed read at the bottom of the dashboard. Could this be from the magnet being backwards? Or is this a common occurrence from the sensor.
