How to model a curvy wing tip

[numbthumb]

OK, so I must be missing something really obvious, but I just cannot wrap my head around this.
I´ve decided to rebuild some of my airplane models, but I am having trouble understanding the right ( or the most convenient ) way of closing a wingtip it usually ends with a quite smooth & round cover, as shown in the image

Or should I just stick to square wings?

You can either use EEbyR or Curviloft. Attached is an example to run either plugin on...

I didn't spend much time with the Trailing Edge as you asked on how to create a smooth end. I could be misunderstanding the question too?

Here's a screen-shot of a three step solution based on Rich's curves & my EEbyRails - took two minutes...

Darn it, I should have stuck to balsa wood - I totally forgot about these plugins
I also assume that, depending on the airfoil shape, you can model the upper and the lower part separately, and then "glue" them together?
Thanks for you replies, guys! Tutorials I have found usually involve some kind of mesh smoothing, but I don´t think that SDS would be a better solution.
Thanks again!

No problem. To improve the mesh you can increase the number of segments in the polylines. Curviloft does allow you to play with the mesh somewhat so that's a good choice.

Thanks, Pilou!
Now it really gets me thinking about building a whole thing that way - something like this could be a good start
