Thanks, Virginian. I'm in Florida...I'll see where they're located.

My glue test results. Both the titebond and 3M 77 pieces were in water for over an hour. Neither showed any signs of coming unglued. The titebond piece actually looked better than the 3M 77 piece as the edges were glue-filled. I could pull the edges of the 3M 77 piece slightly apart. I'm going with the Titebond II. I'll cover the foam with paint of epoxy to seal it.

I got started cutting and glueing my foam pieces together. This blue foam really sands beautifully. I just ordered a radio set, so I'll have to wait for that to arrive so I can set up the parts to balance the boat and see where to install the engine. I decided on making it pull rather than push...less complications.

Already, the plans have evolved. The hull has gotten a half inch thinner, the engine turned around, and more shaping of angles to curves. I'm undecided about putting a skeg on the bottom until I see how it performs. A true airboat is flat bottomed so it will slite...that's what makes them fun. It will be a week or so until it gets asembled and then I'll post a build thread.
