Ok then I'll go with single servo in the middle

Should I fiberglass the center section first then cut a box for the servo or cut the box first then fiberglass last?

What adhestive should I go for center section fiberglassing ? 30 min epoxy or polyurethane or resin type?

I will head to store and get music wire to build as torque rod - what size should I get?


Thanks all for the answer.
