Try a Graupner - You'll never go back. Of course, you can always use your old props for stirring paint

What size prop will you put on a Seagull Extra 300S (60) with a ASP 71 Four Stroke engine upfront?

Okay then I guess my friend is using the right prop. He says his plane is slow and says the plane has little vertical now wants to change the prop (he is comparing it to my 61 2 stroke which is on my 46 Edge). Thanx Minn. So if he changes it shouldn't be to far from the 12x7.

Start with a 12x7. If he wants more vertical, he could try a 13x6

Why does the 7 drop to a 6 - is this your pitch?

Minn, should that Extra with that engine perform well?

Yes, the second number is the pitch, Dropping down in pitch is the equivalent of going from 4th to 3rd gear on a car
