Vulcan (oz9074)

About this Plan

Vulcan. Radio control pattern plane. Wing area 620 sq in.

Quote: "The Vulcan is an excellent pattern ship with jet-like appearance. It is set up wills a swept mid-wing in-line con-figuration wills no dihedral and 0-0 incidence. The original idea for the Vulcan was conceived by John Hedspeth, a fellow member of the Tucson Radio Control Club. Since that time, both of as have been working and improving on that design with the plans, as presented in this issue, being the latest version in the series.

It is truly an outstanding performer, and being a very clean design is quick but still very easy to fly. Although it lacks dihedral, the swept wing does give it extremely good stability. I am sure that you will find the Vulcan as exciting to fly as it is easy to build.

Construction. Fin and Rudder. The empennage is constructed from 1/4 in balsa which is cut to planforrn and then sanded to shape. Use a DuBro wire horn or bend one from music wire for the rudder control linkage. You must install the rudder and fin on the fuselage prior to installing the stabilizer. In addition, be stare to hook up your pushrod at the same time. Then, glue the 1/2 in triangular stock at the fin and fuselage junction for ad-ditional strength in this area.

Stabilizer and Elevator. The stabilizer is also swept making necessary the use of two separate control horns. The DuBro strip aileron set, # LB89 works well for this application. The push rod will need two adjustable Kwik-Links at the stabilizer end (see pattern plan for pushrod). After you have cut out the foam blanks, trim the center to obtain the right amount of sweep. Epoxy the two halves together..."
