Material for control surfaces... - what to choose.
How about sheet Lexan polycarbonate, which comes in different thicknesses. Much less brittle than plexiglas, sands and shapes/machines easily, and takes paint well. I made some bow planes and skegs that worked out well.
I like to save a buck where I can, so I have used plexiglass for all of my control surfaces. The kind of plexiglass I am using (if there are different kinds) is not brittle at all, and even though I have not tried them out yet, they seem to be very durable.
Jon,
I guess I'm not the best driver, but I have run my subs in some tight places around docks and in test tanks that have interior metal beams to support the glass walls, and have broken quite a few "original equpment" control surfaces.
Plexiglass is a brand name for acrylic. I have broken and repaired many acrylic products including an acrylic WTC, which fractured when I tried to insert an end cap.
I still recommend polycarbonate, like Lexan, for these uses, in spite of the additional cost.

Yeah, you're probably right.
One problem I have with the translucent and transparent materials is even when painted they let an unscale-like bit of light through. What do you do about that? Just live with it?
Jon
