Default RE: 3-bladed prop size?

Yes but like any other engine/plane combo you still need to test prop sizes to find the one that will fly the plane the way you like. Prop testing was one of those things I couldn't get into when I started flying RC, that's a big bunch of money to be tossing at them when you have something hanging off the end that is flying your plane. Then one day a friend handed me a bunch of props to try and when I hit that magic prop it was an eye opener. I tend to like my planes to fly slower but have better thrust so I use longer props with a smaller pitch. During testing on one of my planes I discovered the plane didn't fly well with that thinking so I went shorter and more pitch and the plane flew just how I wanted it to. There is a starting point but no set rule for prop size, it's how you like the plane to fly that counts. As long as the prop doesn't lug or over rev your engine it's all up to you. Have fun with it!!
