Instead I used the following:-
1) cp to cp or cp to wood binding. Sand the CP surface to make it rough, use cement glues yamato brand (I bought 1.00 buck at the general store).They stick very well.
Some people uses flame flashing the CP surface to remove the oily residue before gluing. Unless you know the technique, its best to use other method.
2) For surface movement horns, I use mostly discarded PCB cut it into an inverted T shape or buy commercial horns.
3) Servos mount, either I use the EVO mugi method, Strong double sided tape with cable tie, servo tray method to hold the servos. sometimes double sided tape and strong duct tape to hold the servos.
You can go to this link...
It shows step by step how to built a SPAD. This SPAD has the wing specially folded to yield nearly symmetrical airfoil between the top and lower wing. Symmetrical chord wing are very good for aerobatic performance.
In addition its chord thickness is well tapered. This result in a very reasonably good wing airfoil design.
