ROSE PARAKEET - George Jordan
Review by Chuck Spencer 821

Now, this quarter I have four sets of plans for the guys right out of the Twenties and Thirties! The first is of a Home-Built, I think, called the ROSE PARAKEET. This plan was drawn by George Jordan out of Cocoa, Florida and is marketed through Scale Plans - Photo Service, address listed above. The plans are of a full sized Rose Parakeet based in Florida. The plans look great. The scale is One Third: Span of model is 80 inches.

Plan Sheet One: the plan shows a Q-35 for power but it would be great with a Saito 270 or an OS 240 four cylinder. Fuselage is built up of 1/8" ply formers and quarter inch dowel as longerons and stringers. Cabane struts are 1/8 inch music wire faired with balsa. Landing gear is 3/16 inch music wire and the shock struts are simulated. Fin and Rudder are built up of balsa and a CB tailwheel or the new scale tailwheel out of Australia could be used. A nice touch is the provision for an adjustable incidence stabilizer, which is ground adjustable and can be adjusted without taking the plane apart. Wheels are 6 inch DuBro. The Q-35 is mounted on a box attached to the firewall. Engine cowl is available from Fiberglass Master. The fuselage plans shows a half top and half bottom view of the fuselage.

Plan Sheet Two: this sheet shows the left bottom wing panel, the top center section and the right stab and elevator. Airfoil is symetrical and ribs are cut from 3/16 inch balsa sheet, with the root rib 1/4 inch ply. Ribs have compression bracing and the ailerons are on the bottom wing only. Both front and rear spars are of the "I" beam type. There is one false rib between each full rib. Ailerons are top hinged, with the bottom slanted leading rib and are almost full span on the bottom rib only. The center section of the top wing is built the same way with compression bracing and quarter inch ply end ribs. The cutout in the center section is of laminated balsa strips. Four threaded hardwood blocks in each corner hold the top wing to the cabane struts. The stab and elevator are of balsa and construction the same as the fin an rudder.

Plan Sheet Three: this sheet shows the right lower wing panel, the interplane struts and the wing rib pattern. All ribs are the same except near the tip and the top wing is constructed over the bottom wing plan and is one bay shorter to allow for the center section. Between the wings bracings is sort of a Warren Truss deal consisting of a piece of 3/16 inch wire faired over with balsa forming a lift strut. Wing panels are held to the airframe with steel straps. This is a very good set of plans and should make a very substantial and flyable Giant plane.

Construction Notes: these drawings show basic outlines and constructions and are intended for the experienced builder who likes to do his "own thing" as far as details, radio installation, and style of building are concerned. Using these drawings and detailing with the 3 views supplied, will produce an accurate replica of a great flying aircraft!

Fuselage and Tail Assembly: the original model was built using 1/4" to 3/16" diameter dowels for the fuselage, tail assembly and wing tip construction. They are inexpensive and have proven very strong. The wing tip and tail surface outlines are spacing nails around the inner outline of the surface. The more common balsa/spruce construction is shown on the plans as an alternate method.

Wings: For ease of transportation, the upper wing is drawn as a 3-piece assembly; the wing panels and separate center section. For easier construction and assembly, the upper wing may be built in one piece. All wing struts on the original were built using K&S streamline tubing with machined aluminum fittings. Piano wire with spruce fairings are shown on the plans, not as scale but far easier to build!

Landing Gear: the original model has a scale built-up landing gear assembly with bolted machined fittings and strut ends and working bungee cord shock absorbing system. For simplicity sake, a typical piano wire type is shown. The real type shock system is well worth the effort if you want to take the time to build it. Refer to the enclosed three views for details. The tail wheel shown is a C.B. Associates pre-made assembly. Be sure and put in a slight amount of toe-in in the main landing gear for smooth tracking on take off.

Cowling: the fiberglass and aluminum cowling is available from the designer at the address shown. The dummy engine cylinders are available from Balsa U.S.A.
