Yesterday I installed a MAUCH HS series 100A current sensor. I have a Tarot 650 Sport frame. FC is a Pixhawk 2.4.6 running the latest stable AC firmware.
The previous sensor was the ubiquitous 3Dr style rated for 6S and 90 Amps.
The MAUCH sensor is mounted between the rail mounted battery tray and the lower frame plate.
Pixhawk is mounted on a vibration damper mount that is attached to the top plate. The Pixhawk is approximately 50mm above the current sensor.
The M8N GPS/compass puck is mounted on a fiberglass canopy. The GPS puck is approximately 85mm above the MAUCH sensor.
I am using a Taranis X9E running Flight Deck telemetry
Prior to installing the MAUCH I have had NO issues with either compass. I did a test flight this morning and after about 5 minutes or so of hovering I switched from Stabilize to Loiter and shortly there after my radio started “pinging”. I glanced down at the display and saw “EKF2 IMU1 ground mag anomaly, and EKF2 IMU1 switching to Compass 1.”
