Hi all,
I just tried out my my new montec's and one of them makes a whistling noise has anyone had this problem and solved it? FYI, I am using a carbon express arrow and i did spin test my bh before gluing my inserts. Thanks for any info

Whistling is usually a prime indicator of a misaligned broadhead. You need to spin check it again.

Montecs just seem to whistle. I tried them last year and made absolutely sure that they were aligned and spun perfectly. They still whistled. Quite annoying huh?

For what it's worth i was using a full helical set up for my fletchings. Maybe just an offset will make less noise???????
