- It increases up to a point, then it drops off. Which is why you can
- only go a certain speed with a low pitched prop but can exceed that
- speed with a higher pitched prop. Which is why one often can't have
- unlimited vertical climb even if static thrust exceeds weight (see
- Francis Reynold's column in Model Builder 3-4 months ago on vertical
- performance). Which is why props can act as brakes in a dive.
