Thank you all for your kind suggestions and offers. srw1960 - I think that you better save those hinges for your upcoming hovercraft project... you are gonna need them!
I was not able to post my progress today because I had a lot of stuff on my hands... and I pulled my hamstring muscle a bit during the weekend. However, I was able to make the rudders on Sunday, and boy did they turn out great! (IMHO) They are very smooth and easy to turn yet they don't woble at all. They have 160 degrees of rotation before any binding occurs and I don't think that I even need that much. They are all removeable and can be fixed easily, and weigh slightly less than an ounce all together. I will add pictures and a description of the build process in the next post - my camera battery needs to charge.There is a minor down side to the new rudder instalation - I have to change my lift fan switch location, but I foresaw that problem and only tacked the switch on with a bit of CA when I installed it. I guess I will have to make a clever linkage for this one.

about the lobster boat - my friends call it the lobster boat because with its "unique" cover and sponsons, she resembles a lobster... and she used to be a slow one at that. That was before I put a BL and Lipo in it. On Saturday I brought her to the river with me and drove around. I still need to sort out my COG and turn fin, as she is slightly unbalanced, but even with that, she Gps'd at 32 mph in a calm pool.
