R/C Roamer (oz5362)
About this Plan
RC Roamer. Radio control sport model.
Quote: "Ruggedly built, this license-free 62-inch ship can boast the most in advanced radio control designing. R/C Roamer
AS radio control flying has become more and more popular in recent years, several design characteristics have proved desirable for good performance, They are tricycle landing gear, moderate wing dihedral, twin rudders and a fuselage profile having a low center of lateral area - features that have been designed into Roamer.
General dimensions of the ship are: wing area, 670 square inches; wingspan 62 in; weight 4 lb; Wing loading 10 ounces per 100 square inches. Power is a glow-plug Arden .199; power loading is over 300 ounces per cubic inch, so the ship doesn't have a screaming climb, but it flies and glides fairly fast. Larger engines up to .29 cubic inches could also be used for speedier performance.
Roamer is not intended to be a beginner's project. It takes an old free-flight hand to tackle the building of this ship, therefore a detailed explanation of construction is not included here. The plans and photos tell the story.
Fuselage construction can be tackled first. Since the fuselage is longer than 36 in, the sheet balsa sides are made in twb pieces with a diagonal splice under the side windows. The Plywood-side doublers are cut out and the spliced balsa sheets are glued to the plywood. Clamp and let dry thoroughly.
Next cut out formers. Note the lightening holes in the plywood formers and the holes for the escapement rubber in the rear former. The two sides can be joined to the formers upside down over the plan top view. Omit the plywood cabin formers until the structure is taken up from the workboard..."
Quote: "Hi Everyone - Here is another rare model airplane design scanned directly from my copy of Cal Smith's Book of modeling 1952.... This was a single channel rudder only 1952 vintage RC - it looks like it would fly wonderfully with the trike gear and distinctive twin rudder design!"

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
