Gday, I have switched the blades on my Benzin to the 427's. When I start throttling up I'm getting the "fwaaap" sound and of course you can see one blade at a higher aoa than the other.
I do not have a tach so i'm really not sure what my rpms are.
Any advice?

Howzitgoin' eh? Goin' fast in the "Great White North"

What blades did you have on there before? Did you not have the head tached with them either?

When doing your setup on the bench did you check the blade pitch on the new blades. From your description it sounds like your blades are out of track, but I really recommend you get your head tached, check your blade grips, and go back over your bench set up.
