cock Feather up/down

[bengal13]

I just read the review on the Thunderhead Broadhead. In the review it was stated " cock feather up" usually gives the best flight. I would appreciate an explanation on this. Why is this so? When I got my first bow, the shop I went to at the time set me up with the cock feather down.......You mean it makes a difference? How so?

I am in a huge learning curve since finding this site! I've learned a lot and look forward to a continuing education. Thanks

BT was refering to indexing the blades, not the vanes. with some heads the position of the blades, in relation to the string, can cause better or worse flight. Having your odd feather up or down has to do with what rest you shoot. I drop away or whisker bisquit should be shot odd vane up, 2 prong rests should be shot with the odd vane down.

Hey , thanks for the information. You still helped me, in that I got my new rig in January and it has a whisker biscuit rest. I've been shooting with odd feather down. I'll start to shoot as you suggest. It will be interesting to see if things improve. Thanks

Glad to hear that the site is providing some useful information.
Don't forget that our sponsors afford the opportunity for us to do so

Always make sure that your broadheads fly correctly regardless of how they are indexed.
The fletchings can go however they need to but it is the head that is important.

I have (on occasion) been able to correct broadhead flight (somewhat) by placing the vanes in contrast with the head but that is only in cases where the fletching were 5" and fletch straight.

I'm of the school of thought that the 3 blade heads most always fly better with one blade at 12 o'clock. My cock fletch is out from the riser and this has always been my most successful position. I also use my fletch as a kisser in this position but only because of my unusual long draw that I have shooting a short AtA bow. Bottom line is to try all combinations and see what works best for you and the head of your choice.

My friends dad told me to shoot my cock feather out when I had my first bow.... Whenever I was shooting my bow @ the shop he told me to shoot it up..... I should try to shoot em different ways and see how they fly different..... With my broadheads there isn't a difference,......

The difference in location of the fletch comes at the desire of the rest.
If you have a drop away or whisker biscuit it is irrelevant.
With rests such as a shootout through , the cock vane should be at 6O'clock and with shoot around rests the cock vane should face away from the riser.

The idea is to place the vanes in the area least likely to have contact or at least have the minimum contact.

With the Quickshot Biscuit, you shoul have all vanes going through the brown bristles and none in the black ones or the opening.

Good catch Skipmaster

The other caveat is this: "It don't matter where you put the cock feather - it's your preference; but you do need to have the best fletch clearance possible!" Some people are used to cock feather out - with a shootthru rest like BT was describing the cock can be "out" at 10oclock and one of the hen feathers clearing between the rest at 6oclock.

For me it's easist to remember if I put the cock feather down on shootthru's and up on biscuits and drop-aways.
