Task Strakes
« on: May 23, 2010, 01:44:21 PM »
I am working on my Long Ez project, currently working on the wings/winglet installation. Things are going well. In the near future I will be working on the strakes. When I bought the project from the previous builder, it came with a set of task strakes. I have heard of problems with these strakes. Some issues with them being laid up too dry and being prone to leaks. Has anyone heard of or had similar problems? My questions are two fold.

1) Being a new construction, should I go with these task strakes, or should I build my own?
2) Has anyone come up with a simple, light, and effective way of installing these strakes that eliminates this problem?

I have thought of many ideas including laying up new plies of bid on the interior surfaces fairly wet in order to seal them. Also applying a fuel tank sealer similar to what the lancair/glasair uses. Or just simply build the per plans strakes.

Im trying to decide how best/most efficiently to build the strakes, any ideas appreciated.

I've never had any problem with my Task strakes.  You may want to coat the insides with epoxy.  I'd suggest E-Z Poxy.  If you are really paranoid, you could use a light weight cloth and E-Z Poxy to seal the inside of the tanks.  I just gave mine a thick coating of E-Z Poxy (Safe-T-Poxy back then).
