Basic control evaluation. I was very impressed with the ease of control. After 5.5 minutes, I selected RTL and the quad shot up to 15 meters as it’s supposed to do. I read about it in the manual but it was still a bit of a surprise. It landed within 1m of the takeoff position, but I forgot about the horse’s reaction and I was a bit concerned about how he was going to react to the new noise in his pasture.
In the end, it turned out just fine. Archie has learned about the new noise and it doesn't seem to bother him and I've had about 90 flights on the UPair One so far.
