It usually takes me around 50 flights to get an airplane trimmed correctly. even after that is remains a work in process.

I've never spent quite that much time on a fixed wing model, but during the 1990's i flew in F3C and it was around 50-60 flights to set-up the helicopter to be ready to compete and if you crash, your starting from scratch again. And like you said, it was always a work in progress.
