Ok, so today I was doing a midbody repair which involved cutting the rocket about a third up, right above the motor mount, install a new shock cord mount and then couple everything back together. no big deal.
since i didn't have a 2.1" coupler i had to make one out of a spare part of tube, slit, and then used that as a coupler. after i coupled everything back together i rotated the tube around to get a good epoxy layer between the two tubes.
after it is all said and done, i noticed that the two tubes aren't perfectly aligned laterally, as in there is a small kink in the rocket in general at the joint. the rocket is 54mm" diameter with a 29mm mount, about 4.5 feet long. the coupling is about 1 third up the rocket from the back end, and the gap between two tubes on one side of the coupler is a little less than one mm, translating to about ~1.01=B0 differential.
if you hold the rocket and look laterally down the tube, you do notice the kink, but it isn't that bad. i'm wondering how and how much will this aberration effect flight tracking under power (~H180)? any ideas?
thanks!
