Do it over short grass if possible. Use Stab1, first switch position, self leveling. Don't increase motors slowly it is best to jump into the air soon after the motors start.
Since you don't have a feel for how hard to jump, I suggest you blip the throttle up and immediately back down. Always adjust it so that the tail is pointed toward you and the nose away from you each time before you take off. Each time blip it a little more until it jumps a very short way (say 150mm) off the ground. It will either have jumped straight up or it will have tried to flip over. If it tried to flip, you have something wrong and need to fix it. If it didn't flip, try a little longer blip, but don't let it get more than knee high and it if starts to travel, chop the throttle and let it fall. Slow flight from knee high and with no cameras or extra antennas on it, it should not get hurt.
You will be surprised that it is actually controllable. First thing to learn is to control your height to knee high. Then get left-right and forward-backward bank. Do not touch the yaw it will just confuse you.
