Using adhesive for a hinge takes a little getting used to (above left), but once learned will provide you with a tough hinge that has no gaps and is perfectly sealed. Start by masking 1⁄2 to 3⁄8 inch on either side of the hinge line and about 1⁄4 inch outboard of the inboard edge of the aileron. The last bit of masking will prevent the gluing operation for gumming up the working of the aileron. Detail of end masking (above right) to prevent excess adhesive from causing hinging problems. Once all the hinging has been done, it is time to begin marking the details for the trim (below left). This seems most easily done while the parts can still be laid flat on the table. There are several examples of the Dyke Delta that


have been recently detailed in magazines like Sport Aviation. Once the fuselage is detailed, the next item is the top and bottom of the wing (below right). Try to come up with some distinguishing markings so the top can be easily differentiated from the bottom. Things like landing gear holes work well as many of these planes are marked in a similar manner on both the top and the bottom. It would also be good to add the holes for the servos at this time. Then all that is required is to glue the lower fuselage and the upper fuselage assembly to the wing assembly, finalize the hinging of the rudder to the lower fuselage and add the plywood motor mount assembly.


The detail parts used for the motor mount assembly (above left). The firewall is 1⁄8-inch ply and the barbs are 1⁄8-inch diameter dowel sharpened in a pencil sharpener and cut to length. Assembled motor mount (above right) ready for

installation. Drill five matching holes (four for the barbs and one for the motor shaft) in the front of the fuselage assembly. Coat the mount and barbs with adhesive and drive into place. Avoid getting adhesive into nut plates.
