First of all, I always get the best ''power" with A.P.C. props. They're simply more efficient. We
really need to know what airplane you are using. For example, if you are flying a high-winged
trainer with a flat-bottomed airfoil, you'll want a lower pitched prop for slower flight and landing
speeds. Most novice pilots try to land too fast! I know it can seem a bit complicated and it is
when you are trying to maximize performance. Think of it this way; lower pitch is like a lower
gear in your car, better acceleration but lower top speed and visa- versa. O..K? Don’t forget to
adjust the prop diameter to maintain a similar load on your engine. Good luck and fly safely!
