I just recently fletched new arrows and I decided to put them a little more downward than usual. I thought (with my particular fletching rig) I would get more helical twist into it.

However, I ended up with an arrow having about 1,5 " between the nock and the feathers. Is that okay? Or to generalise my question, how relevant is the distance between nock and fletching?

    I don't actually know, so no answer. However, there is some parallel to rocketry. To maintain stability, I need the center of mass and the center of drag pressure as far apart as possible. Moving a rocket's fins (an arrow's fletches) forward, I move the center of mass forward a bit, and the center of drag pressure forward more, reducing the separation and thereby reducing stability. Here's some people way smarter than me to explain it: sciencelearn.org.nz/resources/392-rocket-aerodynamics – cobaltduck Dec 28 '18 at 16:25
