RE: hot glue
I'm not using the glue to actually hold the plane together, but more as something to affix certain things. Things like the landing gear and the servos (couldn't screw them in, was originally using super glue). I also had to get some new piano wire to use as pushrods. The only wire avialable was a little too slim and had a tendency to bend rather than push. I bought some aluminum tubing and ran them inside of it. It works great. The tubing is hot glued to 2 parts of the frame on either side of the model.
A servo is just a motor connected to gears isn't it? If that's true then it would just be figuring our what wire goes where. I don't know for sure, but I'm going to try some things out. Give it some trial and error and see what I come up with. It's not like there will be an explosion if I mess something up. Worst that will happen is that I burn up some replacable electronics.
