We did a recent flight minutes after an attempted break in to scan the area for criminals possibly hiding behind walls etc. We took off from a nearby field and allways stay directly over the flield (just in case).
The APM on AC 3.0.1 has been doing a great job in keeping the Tarot T810 hexa in the air (this frame is epic!) and I'm very happy with a flight time of 20mins (considering the load it's carrying). The Flir is mounted to a Martinez stabilized brush-less gimbal.
