I wanted to do a dry run on my TBS Caipirinha before installing all electronics. TBS Crossfire Tx, Diversity Rx, with TBS Current sensor, TBS Blackbox, TBS GPS/Compass. ESC and motor connected and working. Left my switched on Tx at home, put the bird on the car dash, plugged in the Lipo, all electronics get detected. Normal OSD screen, I waited until I had a GPS lock (solid blue on the sensor). I drove a few miles, but I did not get a "Takeoff detected" message. Did not get any distance or altitude, all at zero. I do have a message "Battery not full" on the OSD because the Lipo is at storage capacity. Is this the reason I don't get a takeoff detection?
