Randy, you said, "Don't let "only 100 hp" fool you, a Sport Cub S2 will not give away anthing to a stock PA18-150, and on 50 less horsepower. The Sport Cub is lighter and more modern and will likely provide years of low cost operation."
You're probably right, but ........ are you sure about the performance comparison?
My guess would be that when comparing a Sport Cub to a PA 18-150 with a pilot, full fuel and typically equipped, that:
- The Sport Cub would land a bit shorter due to less weight;
- The takeoff would be a slight advantage to the PA 18-150;
- Climb to altitude would be big advantage for the PA 18-150.
I confess my ignorance as my only experience is in flying a PA 18-180. So I need an education.
