Quote: "1/2 A Samurai by Rich von Lopez. Construction: There is nothing more annoying than to start a building project and find out that there is some essential item you don't have or forgot to buy at the hobby shop. A lot of time can be wasted because of this. Granted, I like to hang out at the local hobby shop's back room where modelers have been known to congregate and discuss the latest happenings (chew the fat), but not while my mind is set on building. I have limited time for building, so I like to make every minute a productive one. The task of building goes quickly and is pleasurable if all the materials are gathered and ready before the actual building takes place. I will make it easier for you by providing lists of all the needed items in four categories: Tools, Adhesives, Woods, and Hardware.
TOOLS: A modeling knife with spare blades, single edge razor blades, X-Acto hole punches #31/32, X-Acto balsa stripper #48, a paper hole punch, a center punch, a scratch awl, scissors, pins of various sizes and gauges, sandpaper of various grits (100, 150, 200), a sanding block (Mini Sander by Applied Design Corp), fingernail emery boards, a set of Swiss files (X-Acto #7361 or 7356), a set of drill bits, safety glasses, a set of screwdrivers, wire cutters, long nose pliers, a set of small wrenches, a metal yard or meter ruler, a felt tip pen, a sealing iron, a heat gun, glue brushes, dope brushes, a glue gun, a flat building hoard, a drill press or access to it, and a Dremel Moto-Shop or access to it.
Adhesives: Regular cement, such as Testors or Ambroid, 5-minute epoxy, slow-cure epoxy, cyanoacrylate glue, aliphatic resin glue and contact cement.
Woods: Two 1/4 x 1/2 x 24 inch hard balsa, spruce or basswood spars, 1/4 square x 24 inch hard balsa, spruce or basswood leading edge. 1/16 plywood for the motor mount doubler, bellcrank mount, control horn doubler, motor mount gusset and templates, 3/8 square maple or other hardwood for the engine hearers, a 1/8 dowel, 3/8 medium balsa sheet for the motor mount filler blocks, 1/4 medium balsa sheet for the tail boom, 3/16 basswood for the tail boom, 1/8 hard balsa or light basswood sheet for the stabilator and two center ribs, 3/32 hard balsa sheet for the wingtips, 1/16 hard balsa sheet for the wing ribs, trailing edge, vertical webbing, wingtip supports, and cap strips, 1/16 soft balsa sheet for the leading edge sheeting, 1/8 medium balsa sheet for the center section sheeting.
Hardware: A Du-Bro #108 or Goldberg #86 threaded pushrod with clevis, .020 or .025 music wire for the leadouts, .045 music wire for the stabilator hinge pin, 3/32 brass tubing for the leadout eyelets, 1/16 brass tubing for the stabilator hinge bushing and stops, a Perfect #233 or Goldberg #263 1/2 A bellcrank, a long nylon control horn, a small Hi Johnson fuel filter #3FF SM, small Du-Bro neoprene fuel tubing, Flite Lite #222 surgical tubing, Perfect #214 leadout eyelets, copper wire, Perfect #256 aircraft bolt set, 1/4 ounce of lead, covering material such as rascal, MonoKote, or Solar film and carbon paper for making the templates.
Templates: One needs to make templates for the wing ribs, mono-boom, bellcrank platform, wingtips, wingtip supports, and the motor mount outline. Remember, all the parts you cut out will only be as good as your templates, so take your time and do not rush the templates. To make the templates, you will need some 1/16 plywood, carbon paper, a pencil, regular typing paper, and the 1/2A Samurai plans..."

User commentsThe larger (38 inch) Samurai plan and article appeared in Model Builder May 1978. This here is the (28 inch) 1/2A Samurai, and I have no record of which mag it appeared in.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
