    Anyone have time to crack out a quick Rocksim for me? Working on my scaled down/test version of my L3 project and just realized I cannot correctly locate CP with Open Rocket since it can't place fins on a curved surface. Canards need to be re-located to 3.8" from the tip of the NC. Can't justify spending $120 on software that I doubt I'd ever use again. If the small scale version works out I'll be needing further sims for my 6" version. Only thing I really need is an accurate CP(s) 2 total, for the canards in the both file above and the following. Thanks in advance...And I'll send Ya something cool for your efforts...

    You're right. In OpenRocket there isn't a way of putting fins on curved surfaces... But it can be faked...

    I have two methods... A surface mount. Or the easier method using fin tabs (like I used to this lil' beauty).

    The method is the same, you just need to move them a little farther forward than I did.
