Prop question

[macojoe]

When buying a new motor you don't get a prop, you need to tell them what you have for motor, then what you are putting it, let say V20, weight, and use.
Most the V20 are using a 17 pitch, when I had mine and used heavy loads I used 15 x 15 1/2, great out of hole and heavy loads but you lose on top end.

Most any prop shop will get you close to what you need after you supply info, and have demo props for you to use to see if its the one you need.
