I was flying an orbital around the AIG building in Houston, TX, with a Mavic Pro. Mostly because I thought it would be a really cool shot. Before take-off I set the RTH altitude to be 392 feet. I knew that the height of this building was greater than that besides I wasn't planning on losing connection. I've seen so many different crash analysis reviews on the forums that I thought I could just fly up about 75 feet more when I got to the back side of the building. Yeah, that extra altitude thing didn't happen. I went from near 100% signal to zip, zero, nada in no time flat while flying. I lost connection for about 30 seconds and all I could think of was that my drone crashed into opposite side of the building trying to RTH when it lost signal. When I finally got signal back I didn't even see the building and knew I was safe. Phew!
Ok, fast forward to downloading and viewing exactly what happened. I feel sick seeing just how close my drone came to being in pieces or stuck on the top of the building, or both. There were a couple of antennae that may not have been seen by the obstacle avoidance and could have been the downfall of my drone. I've posted a short clip of what the drone did right after it lost connection and initiated RTH as it should have.
For learning purposes, both mine and the readers, I've posted my log from this flight
Flight log
Finally, the knowledge that I would like to gain from this is does the RTH altitude stay the same if I'm already above what the max RTH is set to? The drone goes up a few feet on its own. Is that the obstacle avoidance seeing the top of the building? Right when it got to the top of the building it stopped because it sensed something. Was that the building itself or the small antennae that it somehow detected...thankfully?
