So, I have logged about 47 flights for like 6.1 hours of flight time with the MM. Today for the first time I got this weird "sensor error" seems pretty broad to me. Everything was flying normal however the return to home had it landing about 20 feet away (fixed it on the land, but also made sure there was good GPS before takeoff). Either way, it was around dusk so light was getting a little darker... could that be what the "Sensor Error" is? lack of light?
