Jarvis,

yours does sound like the Saphir II. It was designed for a 120 4-stroke I believe. The bottom pan is a single piece - chin cowl and fuse bottom? If so, it is a II.

I don't recommend CA hinges on foam core surfaces (wing & stab), CA will eat the foam. There is foam safe CA but personally, I find it doesn't work that well. I also find that the design of the surfaces doesn't lend itself well to CA hinges but it could be done if you really want to. I just don't know how well the foam safe CA stuff holds on to the hinge material. One is supposed to use thin CA and foam safe ain't thin!

I'd suggest using poly glue or epoxy. You can use DuBro or Robart type hinges. If you haven't tried the hinge points, you might want to give them a try. It is very easy to install them and they are solid. It's a fairly large bird and the controls are not light which is also a reason why I prefer plastic hinges.

If you don't use hinge points but use flat hinges whether plastic or CA, install the hinge just under the sheeting of and along the top airfoil. I really can't see CA working though. Fine on the rudder though if you wish - it's solid balsa.
