Like Frank, when I started launching rockets regularly in 2020 I have been keeping relatively detailed records of flights and motors used. Since then I have logged 191 launches between my own local fields and flying with CMASS.
I have a few rockets now at or approaching 20 flights:
21 Flights - Scratch Built Saturn V (3 18mm Motor Cluster) - Been in need of multiple repairs to the overscale sized fins. Also seen a few anomalous flights/crashes due to 1 or more motors failing to ignite. Definitely has more flights in her, although I might remove and replace the motor mount for a single 24MM option.
19 Flights - Scratch Built Falcon Heavy (3 18mm Motor Cluster) - This baby follows SpaceX's full reusability principals. Even after a significant lawn dart by Center Core once and a couple flights where the booster shock cords got caught on the release hooks at burnout causing the center stage to spin around. Many repairs to the polycarbonate fins, but my FH is ready for more payloads.
17 Flights - Upscaled Estes SR-71 (24mm Motor) - The Estes kit was a childhood favorite build of mine which was lost on it's maiden voyage, but from reading reviews it was likely desitined for a short life even if recovered. So I upscaled it to make it easier to pack a larger chute, and it flies perfectly arrow straight. On its 16th launch a faulty motor resulted in a spectacular lawn dart. But I was able to make repairs and it returned for a perfect 17th flight, with more to come.
