So I thought if I set the height and distance limits as low as they can go and went in the middle of my yard I could "safely" let my kids try my P3S. Set the height at 20 m, and distance at 15 m. Let it reset the home location and launched. To test it I climbed to about 4 ft off the ground I started flying forward... 10 m... 12 m... 15 m... 18 m (why isn't it stopping?)... 20 m... 25 m... FENCE! Shut it down and ran over. Thankfully no signs of damage, not even a visible sign of marks on the props except for minor scuffs. Re-launched and it was flying fine, except the distance and height limits were hit and miss when it would decide to enforce them. Any ideas? Also it would fly straight forward, but backwards and right/left would veer off. Re-calibrating the compass fixed this.
