I have an Apogee Katana kit and am ready to assemble. I like the rocket design a lot - except for the fin profile.
I don’t like that the trailing edge of the fins is pretty much in line with the end of the rocket. Also, the gap looks odd to me - especially near the tip. (see pic 1)
I’d like to cut off part of the trailing edge so that it sweeps more forward. (Of course I’d need to recalc CP.). If I modify the trailing edge, I think it could cause the fin to be weak in the area of the “gap”. I’d like to fill in the outboard gap with something to strengthen. (See pic 2)
The question is: What would be good to use to fill in the gap? Rocketpoxy?
I’ve seen that done somewhere else on the forum, but now can’t find it.
Any advice would be appreciated. Thanks!
