As always, it looks good Justin. Greg Olson
Bring em up to WI, I can bevel them right quick!Justin you have some mad skills with those bevels on 1/8" G10 fins.
I had mine cropped a little more and a shout out to Composite Warehouse for not charging any extra.

When I design fins or modify an original fin design, I just iterate until I get the stability I need for the biggest engine I'll use. First get the basic fin shape you want. If the stability is too low, increase the root chord and semi-span dimensions proportionally until you get the stability required. If too high, do the reverse. When you get it to where you want it, then adjust the TTW fin tab parameters to fit your MMT. The fin tabs slightly shift the CG back, so a final iteration may be required.Neither, I'm using open Rocket. Looks much better and now I see the problem you're pointing out with a long motor case.
Since you're light years ahead of me with rocksim, do you think cropping the fins would have any stability issues?
Will there be a micro bee as well?I'm liking the way they turned out with the cropped fins. Time to start the Lotus 8.

I think the non metal tip starts out life as a FG rod.Of course, lol.
The fake metal tip turned out nice on the 3".
See you in June.
Gary,I designed the LOTUS Series for Composite Warehouse, Here are the real Rocksim files. Just change the weight and the CG to what your kit comes out to. Also I use a ratio between Rocksim and the Barroman method to determine my CP. Here is what I recommend for the CP for each size LOTUS.
3" CP - 25.65 from the NC Tip
5" CP - 39.94 from the NC Tip
8" CP - 62.40 from the NC Tip
