OK, I've got my trainer fuse setup, getting my water rigging done, and I'm almost good to try my maiden off of water this weekend. However, when I was testing the structural integrity of the floats (OK, I was playing with them), I noticed that one of the screws kind of reamed out the hole it was in, and came loose. I could pull it out with my fingers. These are just plastic floats and the only hardware it came for mounting the struts to the floats were screws that you screwed directly into the plastic. I replaced the hardware that mounted to the fuse, but figured the screws in the floats would be OK. Guess I was wrong.

So I'm thinking that I could buy some threaded inserts or threaded post that I can epoxy into the holes I have. I'll probably replace the screws they gave me with new 6-32 ones from the hardware store too. Would this be the way to solve the problem? Is there something better? I'm looking for any and all advice that will keep me from loosing my place to the bottom of the lake [:'(]

----UPDATE----
Just thought you guys deserved a quick update, since you all helped make this a very happy birthday for me. Despite some trials and tribulations with my floats, I got them reinforced by sandwiching fiberglass between the float and thicker piece of plastic. So far, this seems to be doing the trick and none of the screws on the floats have loosened up since the addition. I was able to make a total of five successful flight. Plane is still in one piece, so that's good. The only thing I don't like is my pull-pull setup for my water rudder. I can't seem to get it dialed in just right, it always wants to travel one way better than the other. I was able to steer, but everything I read here is right, taxiing cross-wind can be a pain. Hopefully it's something I'll get the hang of. I'm attaching some pictures of my setup.
