Super R.O.G (oz1508)

About this Plan

Super R.O.G (Super ROG). Free flight rubber stick model.

Quote: "Some of you old timers must surely remember the ROG's (rise-off-ground) of a bygone era. Designed primarily as a training aid for the aspiring modelers, these designs usually ranged in size from 12 to 18 inches in span. As a rule, the smaller designs were constructed entirely of balsa, while the larger versions departed towards a built-up flat frame for the wing which was covered on the top side only.

However, this atomic age that we are in now has affected everything: even the lit' ol' R.O.G.! Witness the Super R.O.G. featured in this article; a fair sized model by anyone's standards, yet easily built.

In designing this R.O.G. we tried to combine the advantages of size, related to good performance, something which was very limited with yesterday's R.O.G.'s. Yet perhaps equally or more important is the fact that structural refinements have been added, which are just as easily accomplished as if one were building a small size R.O.G.

There are no ribs to cut out, yet the wing has a desirable top curvature by virtue of the way it is constructed. Such a wing is also light and strong. All the parts that do have to be cut to a pattern shape are by no means critical, so if you're slightly off, don't worry about it.

Sounds inviting doesn't it? Chances are, that you prob-ably have all the building materials on hand, with a few possible exceptions, so let's dig into it right away.

Construction. Beginning with the main fuselage, select a firm piece of balsa as specified and cut to the desired length. The cabin and rear fuselage top can be cut from a medium grade of wood and cemented to the main fuselage. With the aid of a straight edge and modeler's knife, cut the fuselage to the required outline. The wing mount platform consists of 3/16 x 1/4 supports on each side of the fuselage as indicated on the plan. Cement them in place and when thoroughly dry, 'V' notch the top to obtain the desired dihedral angle. Then cut the 1/16 plywood platform to size and recess it into position as indicated. Apply a liberal quantity of cement to reinforce the completed assembly.

The landing gear strut is bent to shape from 1/16 diameter piano wire and cemented to the fuselage. Secure the landing gear position with thread binding and liberal quantities of cement.

A suitable thrust bearing should be available at well equipped hobby shops. Should you experience some difficulty in obtaining one, it can be made from a piece of 1/16 dural as shown. Thread binding as shown or some cloth tape reinforcements together with cement are used to secure the thrust bearing in position.

The wing is constructed in two halves. Beginning with either half, position the leading edge on your layout. Then cement all the 1/8 square rib bottoms in position, except at wing center section where rib bottom is 1/8 x 1/2 sheet..."
