[QUOTE="nilanjan118, post: 87329, member: 13902"] Yes, you have a faulty bottom sensor which is sensing ground or an obstacle even at altitudes where it is not supposed to. The AC going up on its own is normal in such circumstances. Also the altitude display flickers between IMU altitude and VPS altitude giving you absurd outputs. One way to avoid such erratic behavior is to turn off the bottom sensors. Now the official Go4 app doesn't have this option for the Spark but I have heard that you can turn off the sensors by using Litchi app. I don't have any experience with using Litchi but if I recall correctly, I remember reading in some old thread that it is possible to use Litchi app to just turn off the bottom sensors and then fly with Go4 app. Of course when you do so, you will lose the damping effect of the AC coming down while landing and should be very careful not to cause a hard landing or crash. If you do not want to spend money on repair, you can at least invest $25 on an app which will solve your problem and also give you a handful of new features as well. [/QUOTE]
