I've been thinking about going for the 1000' altitude mark ever since getting my aircraft. I got tired of making excuses for not doing and decided wind be damned, I'm going for it. For safety reasons, and the high winds out of the south, I picked a good open field with nothing but grasslands to the north. Everything starting off great, kept climbing and climbing, checking telemetry continuously while trying to maintain eye contact at which I gave up around 700' and just concentrated on the screen. Then I hit about 1050' and stopped ascent and I was going to rotate 360 degrees for the view but as soon as I turned 180 degrees, "Loss Of Signal"..1...2...3..."Coming Home". I thinking OK, I'll wait till it gets to about 700 then move S1 to middle and back up to regain control. Well, the thing is, it wasn't descending. I'm at about 70% on battery. I'm not sure why I didn't see or notice a descent. I'm wondering if somehow the wind could have been a factor making it an EXTREMELY slow descent. I didn't wait to find out and started toggling S1 between top and middle, and for the few seconds I had control, I'd lower about 10 feet. I finally reacquired full control about 700 feet I think and continued to bring her down. One other strange thing is that I had a nice, smooth touchdown, but as soon as I landed, I got the message. "Compass Malfunction Maintenance Required". Have no idea what brought that on but I powered everything off, recalibrated and did a quick test flight with no other compass errors. Any ideas on that? Thanks in advance. A couple of problems, but it was good experience in the end Regards, J. PS I'll have video of my 1000 ft climb and LOS in just a bit.
