Flew the other day and reached a max altitude of 196 feet with a distance of 150 feet directly in front of me. I was experiencing no issues whatsoever. However, no matter how much I searched, I could no see my Mini. So, I got to thinking about adding lights to my Mini. Along this same line of thought about adding to my Mini, I've been contemplating adding landing gear/extensions also. Another however. By adding several accessories to my Mini, it's weight will exceed 250 grams. I want to do the right thing and stay out of trouble. I assume by exceeding 250 grams, I will now have to register my Mini. Is that where Part 107 comes into play? If so, will I have to take any additional steps every time I fly?
