I was flying the other day messing around with the active track trying to lock into cars, at some point I stopped and tried to fly the bird towards me and it wouldn't move. The altitude and yaw controls were working but no horizontal movement. I then tried to RTH and it rose to the set height but still didn't come towards me. I then turned off the rc and it immediately started to descend even though it was set to RTH on the rc lost signal...also I noticed it wasn't reading the height correctly because when it was at 50m and I turned off the rc it immediately read 35m....anybody know what happened? Here is my flight log..incident around 11 min mark Phantom 3 Log Viewer - PhantomHelp.com
