About this Plan

Cessna Skymaster. Radio control scale model for .30 to .40 engines. Merco .35 shown. Scale is 1/6.

Quote: "Construction of the Skymaster: Begin construction with the horizontal stabilizer. Stack all the ribs (S-3) together and carefully drill the hole shown for the vinyl pipe (which houses the rudder interconnect). Cover that portlon of the plan with waxed paper and pin S-2 in place, next glue and pin the S-3 ribs in place. Finally, slide a scrap 3/16 or 1/4 in square strip under the front end of the rids to support while pinning in place.

Now, carefully glue the S-1 in place and double check the alignment by sighting along the structure from either end, when dry, remove from the plans and cover both top and bottom simultaneously (to prevent warps) with 3/32" balsa sheet. Hold the sheets secure with tape and pins. While that drys, glue the S-5 tips to the S-4 elevator and secure with tape. When both structures are dry, remove the tape and spot glue the elevator in place on the S-2 stabilizer trailing edge.

Take the time to carefully study all the isometric drawings which have been provided to illustrate details. Don't hesitate to refer to these while actually gluing parts together, especially when you don't understand clearly what must be done. While referring to the fuselage drawings, set all the applicable parts aside and check them for trial fits (with each other not the plans).

Begin fuselage construction with the fuselage sides. Epoxy the plywood doublers in place and add the 3/16 square balsa longeron. Make one left side and one right side. Carefully mark the location of bulkheads F-1 through F-12. While these assemblies dry, carefully measure and draw the vertical center lines on each fuselage bulkhead. Next, referring to the fuselage sideview, carefully epoxy the two engine mounts together using the EM-1 , 2 and 3 parts. Glue former F-3a and F-3 together, drill and mount the nose gear bracket.

Assemble and align the fuselage side, formers (F-1 through F-12) and engine mount assemblies including EM-4, 5, 6 and 7. Use tape and pins to hold securely and insure o the entire assembly 15 aligned and square before the glue dries. Use a 90° triangle and sight along the former centerlines. When completely dry, remove the tape and add all the 3/16 square balsa stringers carefully to prevent stress which might misalign the main structure.

Next, cover the belly, cowl tops and fairing area in front of the wing with the 1/8 sheet balsa planking and strips provided. You may find it easier to install the main landing gear support and fairing prior to planking the belly..."

    ScaleType: This (oz4566) 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/Cessna_Skymaster
    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.

Hello Steve , Enclosed is a photo [see more pics] of actual scale model, Cessna Skymaster. Based on a Royal Marutaka kit. Thanks,

The Skymaster I was referring to was built by a club member Paul Gordon-Brander and has twin 60s for power and a 77 inch wing [more pics 005].

First of all, thank you for the free download which I successfully downloaded and printed full scale on tiled paper. I would like to know how to identify which parts need to be plywood, especially for fuselage construction. Like F5, F7, F11, etc. Your kind advice would be very much appreciated.

Usually when you see an end view of an item with two parallel lines on the inside of the item, it denotes 3-ply plywood. The plan view of model shows that almost every bulkhead is plywood.

The plans don't specify the thickness of the wing ribs and there is no templates for the rudder or stab ribs?
Ken J - 18/06/2019
Ken, if you look at the centre of the tailplane, S3 is quite clearly shown.
As for the ribs - a ruler over the plan shows W1 to be 3/32", W2 to be 1/8"and the remainder to be 1/16"

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.
