The first solo is both exhilarating and scary. Looking over and seeing an empty seat instead of the person that has prevented you from killing yourself up until now, is quite a moment. You're now a helicopter pilot!
Keep it up as long as you're having fun. You hopefully will become more comfortable over time. There will be a point where you will say to yourself: why was this once so HARD? Some people on here think they were born with several thousand hours. You are a helicopter pilot and this is where to ask your questions.
