A large diameter prop with a small pitch won’t give high speed.
Ideally you find an appropriate diameter prop, then incrementally increase pitch until you reach the speed/amp limit. Other than relying on the experience of others (valuable!), you have to find a balance between enough diameter and the pitch required to reach your speed goal.
