As I am wanting to fly higher rockets, and my budget doesn't allow for GPS trackers (pm me if you want to sell), I am curious to know how high you can fly rockets and still see them and have successful recovery. I have plenty of expirience myself, but would like to see what the rest of the community feels the answer is, expecially in terms of larger rockets, where I have less expirience. I understand that many factors may come into play when it comes to visibility such as sky clarity and rocket size, but in general, how high can you launch your rocket and still feel safe about recovery?
