First these types of Micro are the hardest to fly, I would start with making sure your COG is on (Center of Gravity) and that the swash is level and the blades are tracking.

It will have a tendency to go to the right on take off but once in the air and out of ground effect it should fly fairly level. But like I said these bird are very twitchy. But it will come with practice and you’ll be glade to know that once you can hove one of these micros man you can just about hover anything
