RE: Team OMP Presents the Boxxer ARF!
Vertical Fin Install:
1: The vertical fin is aligned by making sure there is a straight line along the rear of the fuselage to the rear of the vertical fin. This line is your rudder hinge line. The fin must be centered on the top of the fuselage. After aligning and centering, mark the location where the fin must be mounted.
2: Cut away covering from the top of the fuselage, approximately 1/16 of an inch inside the marks you made. Also, remove the covering from the bottom of the fin, to allow wood to wood contact.
3: The fin is “butt-glued” on top of the fuselage. Mix up a small amount of 30 minute epoxy and coat the exposed wood on top of the fuselage and the exposed wood on the bottom of the fin. Put the fin back in place, center, and align the fin. Use pins or masking tape to hold the fin in place as the glue cures. If using CA, run a bead of medium CA down the center of the wood you exposed on the fin and fuselage. After that, align, center, pin (or tape) and then apply a bead of medium CA around the fin. Allow the CA to soak for a few moments, then apply CA kicker. With either gluing technique, fin alignment must be absolutely correct, and the joint must be very strong. Again, 30 minute epoxy is most highly recommended for this procedure.
