Nick, these are a few of the things that I have a problem with:
FOC is an issue for conventional fletched arrows because they are not spinning when they leave the bow and in that first few feet of flight any unbalance because of weight or flex due to weak spine is magnified down range and results in loss of accuracy. The TURBO which spins instantly 10 times faster than any other arrow does 20yds down range, basically eliminates spine and FOC.
They effectively increase the spine of a shaft because of the instant high rotation, and virtually eliminate any FOC issues.
Are these theories, or is this something that has actually been tested.
Our first problem was that the original nocks were made from polycarbonate , which was strong, but had a tendancy to break vanes on impact. We solved that problem this past spring when we retooled our molds to accept a new glass filled nylon
So, if I bought the turbos from you in sprong 2003, they were the old style. Correct? Any weight differences?
Another thing that I had a problem with on one of my bow was clearance. I e-mailed you on the subject when it happened, and I believe that you told me that I was the first person to mention that problem. I don't want to put words in your mouth because it was a while ago, but it went something like that. I bleieve that I have read from others on the board that they also had problems. Have you ever considered setting them up differently to avoid the problem, maybe having them come off the bow on an X?
