4 the record, the Airtronics 94761 lasted around 20 hours & failed at odometer reading 13 hours.

Today was 40 minutes in the light wind, no gyro skewing observed, & no computer crashes. Unfortunately, our beloved wind has died. Once avoiding wind at all costs, now chasing after it to expand the envelope.

Unfortunately, with the rate damping done in software, there's not enough PIC power to send telemetry to the groundstation. Get nasty servo glitches with the groundstation on. Kill the groundstation & the glitches go away. A battery display on the ground would still be very useful. A battery LED on the airframe might also work.

Your blog is confusing.
