Been flying with it for the last couple of days. I would have reported back sooner but I'm having too much fun.
Caught a lucky break tonight. Showed my son the RTH function. Took control at about 50 feet and brought it to a good landing area at about 4 feet. Too low to grab. But I couldn't gain the 2 feet of elevation I needed for an overhead grab. So I landed it. Seems my battery was down to 4%. This was unexpected. The battery had been fully charged and flight time was only about 10 minutes. Is power use dramatically higher in "windy" conditions? Did the RTH message override the other warnings?
