Xguard RC Back Plate Self Calibrating Back Plate RPM Sensor V2 With AGC Heli Servo ●TN70 Tail Boom Mount-Left xThe XGuard Self Calibrating Back Plate RPM Sensor with Static discharge protection and sensor power buffering is the most advanced Back Plate RPM Sensor to date. This sensor instead of having a fixed trigger point that might work or not with your particular engine, it works by sensing the magnetic field variation of the first pulses and calibrates itself to the ideal magnetic field trigger point for that particular engine. It measures the max and min
