Tommie,

nice board! The servos you have in mind should be fine. Futaba and JR tend to be more expensive. You could certainly use standard Tower servos on the empennage and an HS-55 for throttle.

Re the elevator, first make the holes at the right distance, then notch the LE of the inboard sections to countersink the rod. Roughen the rod up, stuff some epoxy in the holes and slots and cover the rod (except the exposed middle portion. The assemble on the plans insuring that the spacing is correct and put some weight on the assembly to make sure it is absolutely flat.

Once done, you can then hinge the elevator to the stab. Again, absolute centerline by drawing two lines on elevator LE and stab TE. A simple slot with a #11 will do for the CA hinges. You can later drill a small 1/16" hole in the center to allow the CA to flow when the time comes. Once everything is hinged, flat and symmetrical you can then bevel the elevator LE to 45 degress about the centerline. Stab LE and elevator TE are then rounded and everything sanded smooth. Done!

Rudder/Fin - same process. Ailerons much the same.

David.
