I tried out the Flytrex 3G yesterday it seems to work well and mission was updated to site fine, last seen position was correct too. Nice to see two or three new metrics being logged over the Core 2, one of which is battery level. I am a bit curious about why with a perfectly healthy battery (which gradually degraded normally from 12.5v to 11v during the flight) was logged at 0.21 v on four occaisions. The quad was not being thrown about much, which makes me doubt whether the battery pins are the cause. There were no power problems observed or heard on the quad it flew perfectly. Is this a bug in the logging or something even more sinister ?
