Plan file details

Royal Rudder Bug. Wingspan 62 in, wing area 300 sq in. The Royal Rudder-Bug (oz1730) first appeared in Flying Models, Feb 1954. This here is the design as it appeared when kitted by Berkeley. Includes detailed build instructions. Quote: "The Royal Rudder-Bug is an extremely easy to build rugged Radio Control design in the medium size class. Designed by Dr Walter Good, one of the countries best Radio Control flyers, you are assured of an all around performer. The tricycle gear and ample dihedral make the model stable on the ground as well as in the air. Spiral stability is excellent, ample load carrying capacity is no problem for this model. Start construction with the wing. As the first step, remove die-cut ribs etc. from the sheets, and trim up with sandpaper it necessary. Layout the wing spars first, and join with the plywood spar gussets. There should be 4-1/2 in dihedral at each tip. After the cement has set thoroughly, slide the wing ribs onto the spars, starting with the 5 center section ribs. Lay the wing over the plan, align and cement ribs cs usual. When the panel is dry, remove from plan and repeat proceedure with other half of wing, following outline indicated on the plan. The leading and trailing edges should offer no problem. The center section is now added and planked with 3/32 in sheet . Extra balsa is included on the die-cut sheets for this purpose. The stabilizer is easy to build and takes little time. Pin one 1/8 x 1/4 in spar spar to the plan, blocking the tips up 5/32 in. Cement each rib to the spar, and to the trailing edge. Align carefully as cement dries. This is followed by the leading edge, die-cut balsa gussets and the 3/32 in center section planking. This brings us to the fuselage construction. The crutch is the load carrying backbone in this fuselage, and must be constructed first. Note in the fuselage details above, a 1/2 in sheet balsa floor is used for strength. Cement together at the center line and trim to fit perfectly in place on the fuselage top view. Make sure all edges are square before pinning and cementing the 1/4 x 1/2 in crutch members in place. We suggest you splice the crutch as indicated before pinning over the plan..." Direct submission to Outerzone.
