Plastic flaperon tips

I just slid them in and pop riveted them in place, with a little filler at the trailing edge. If they ever get dinged up, they will be easy to replace.

I know I just ended up spending more time on this than was probably warranted, but I just could not bring myself to simply stuff the tips inside. (Even though the earlier responses show that it can look real good that way.)
I used a 1/2" balsa sheet to provide a flange for the molded tip. I put some sheet aluminum in the trailing edge of the tip as support for that SuperFil wedge.

This just proves that there is more than one way to do things and it is the result that counts.
