RE: Arrow rotation, is it important?
PSE tested the TUBO NOCK on high speed video and found it to spin an arrow two times in the first five feet of flight.
If you do the math that comes to 4800 rpm as soon as the arrow leaves the bowstring from a 200 fps bow. That is better than ten times faster revolutions than a conventional arrow can get up to at 20 yds.
At the same moment in time when the arrow just leaves the bow , a conventional arrow has virtually no spin , while the TURBO at 4800 rpms already has stabilized your arrow.
I have just been reading all the messages on this site about TURBOS and found that most of the complaints are the result of lack of tuning the TURBOs properly. TURBOS fly best around 1/8 inch nock high from most bows using fallaways or whisker biscuits. We have found that the new cam and 1/2 hybrid bows tune best about 1/8 nock low.
We provide tuning instructions with each package, and also have a website where anyone can get help setting up their bow.
When set up properly they provide more consistant accuracy in the real world ,(outdoors in the wind) than any arrow with conventional fletching.
