About this Plan

Rearwin Skyranger. Rubber scale model.

Quote: "THE latest Rearwin introduction into the light-plane field is the Skyranger. Side seating, anti-stall slots and a 75 hp horizontally opposed motor mark its difference from the other Rearwin planes. As a flying scale model, its performance is remarkable. With all its tail surfaces true to scale, it is a very stable flier which, adjusted properly, will turn in excellent flights.

Lay out the sides of the fuselage using medium 1/8 in square longerons and hard balsa for the uprights. If you prefer, the doors can be made to open, but they must fit snugly. Assemble the sides and add the top and bottom formers. Formers #1 and #7 are of hard 3/32 sheet balsa; the other formers are of 1/16 soft sheet balsa. Notch and glue the base ribs A to the top of the cabin. Insert ribs B and the center-section spars. Add the trailing-edge fillets.

Select a medium block of balsa and, using the templates for the engine block, carve and sand it to shape. Refer constantly to templates for accuracy. Cut off the nose block, as shown in the perspective view, and cut the engine block through the center, Hollow each half and then glue them together. Glue a large-face bushing to the nose block.

Great care must now be taken. Center the engine block on formers #1 and #7; glue it to them. Cut some very soft 1/8 x 3/16 strips and plank the nose flush from the rear of the engine block for former #2 on the top, to the rear of the doors on the sides, and to #9 on the bottom. Add the stringers and landing-gear legs. The wheel pants are made in the same manner as the engine block. Shape the fillets and sand the fuselage smooth. Rub in three coats of thin glue, sanding between coats.

The tail surfaces are built up of hard balsa to prevent warping. The spar in the rudder serves as the tail post, and the rudder is built into the fuselage before it is covered..."

ScaleType:
  • Commonwealth_Skyranger | help

    Test link:

    ScaleType: This (oz4345) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Commonwealth_Skyranger
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Notes

* 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.

Scaling

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.
