Correct propeller
I have a pattern plane with a Himax 6330-210 pro motor. I am running a 21 x 13 prop on it and the down lines are quite fast. I want to slow it down some. I use 30% brake, but I run the trim so that the motor has a few rotations at idle. I like that on landing. Best 2 blade, or a 3 blade.
