Hey guys I just got an eachine novice 2, this is my first drone using an fc and beta flight. I used the quad 2 days ago and everything was fine. I went to take it out the next day and all of the sudden when I was trying to arm the drone, then switch to stability mode it would flip over to the left. I could get it to fly in air mode but im not skilled enough yet to do this. I also notice when using one of my switches that also arms/disarms the drone, the throttle jumps to like 47%. I went home and found the fc seemed to need to be calibrated and used the backup I had made. This seemed to help but when I take off it seems I need more throttle and it banks left while moving forward and up. Im brand new to all this stuff and im not sure what's going on. Im using an flysky fs-i6 remote and the drone is a eachince novice 2 toothpick drone. Anyhelp would be greatly appreciated.
