I'm in the process of building an Estes Ventris for the first time. After gluing the first fin on, I learned the drawback of those otherwise-wonderful "laser-cut fins"... my fins are bent. Not to extremes, but bent enough to bother me. I've read that there are ways to reduce the bend, but with one bent fin already glued, and a lack of patience on my end... I'm proceeding as normal.
I understand any fin that is not aligned perfectly will cause unwanted forces on the rocket. And while I am sticking a G80-7T in it once it's done, I'm sure the TTW fin mounting and relatively large surface area to attach the fin to the BT will be able to take the additional forces. But how much, in practice, have bent fins on your rockets caused issues? I'd think that they'd have an inadvertent benefit of spin-stabilizing the rocket at the expense of speed and altitude... which I already have more than enough of with a G80...
