How does weight and power affect an airplane in regards to choosing an engine for a homebuilt AC?
Example, a Lycoming 0-320 is heavier than a Continental O-200, but has more horsepower.
Assuming all conditions are the same and engineering was in place, would you gain a greater useful load out of a higher horsepower engine, or does the higher HP just mean that you would have better climb/cruse performance? I don’t quite understand how that works.
