I just got my spark about a week ago. It was flying just fine when I first got it. I had minor accident recently. I activate one of the one shot mode where the drone flying backward while tracking a subject. Short story it crash while flying backwards, luckily it just minor scratches here and there on the propeller and the body. One of the bottom cover of the propeller fell off, I was able to find it and put it back again. My initial respond was to turn it on again and try to fly again, it was working.  So I store it and charged it again to fly another time. I fly it again recently, and notice something is not right. After I take off whenever I just put it on hover, without moving the controller, it seems to be slightly moving forward or side way from it's current position.To test again it, I decided to fly it indoor as there will be no wind, the same thing happen again. There's nothing broken on the body of Spark, as I was quite fortunate that it only fall about from 70 cm ,to the place it drop. Is this normal? It keeps telling me to switch to Alti mode...is this the reason?

Sounds like you just need to calibrate it again.
