Is it possible to get an arrow to fly straight with fixed blade broadheads using straight vains for fletching? I've never been able to make it work. I've seen people with straight vanes and expandables but not to many people using the fixed blades.

"Hey ya'll, watch this"

I shoot 4" straight vanes on my arrows(ACC's). I
tried 4" helical feathers this fall and switched
back in the middle of the season, main reason
being, I was used to the durability of the
vanes...especially with all the rain we had
here in Iowa. I spend a lot of time making
sure my bow is properly tuned and noticed
little difference between the two with my
set up. I'm shooting 4-blade 100 gr. Muzzy's.

The aerodynamics don't really favor you with a fixed blade broadhead and straight vanes.
As we all know, fixed blade broadheads have the tendancy to plane. If you use straight vanes then your arrow will not spin in flight and allow any small misalignment of the broadhead to continue to plane in the same direction and push the arrow off course. With a helical or offset fletch, the arrow spins, continuously changing the planing force of the broadhead over the 360 degree rotation. This in effect averages out the effect of the planing and keeps you on course. Theoretically the faster the arrow spins, the better accuracy you will have as the instantaneous deviation from straight flight will be smaller (arrow will always be closer to being dead on target), but this leads to other issues in downrange energy and penetration, overall arrow balance, etc...

That was the long answer. The short answer is no, don't go with straight vanes on a fixed blade broadhead, your accuracy will suffer.
