About this Plan

Cessna Airmaster. Rubber scale model.

Quote: "Cessna C145 Airmaster. An ideal subject for small rubber-powered FF or CO2 / .020 small R/C. Flies well, is easily built, yet still retains an authentic look.

ACCORDING TO 'Light Plane Guide' the 1934 C-34 Airmaster was the world's most efficient airplane. The C145 is a slightly later (1939-42) version of this plane, using the same engine (145 hp Warner), and with slight modifications to the flaps and rudder. I had been interested in the Airmaster for a long time as a model subject and finally managed to find one and photograph it at an antique fly-in. I examined the real plane and found it was mostly fabric covered, so a stick-and-tissue model would be easily built and authentic.

Construction is fairly conventional so it shouldn't cause you much difficulty. Begin the body by making two identical side frames. Pin the completed sides upside-down over the top view, adding cross braces to complete the body box. Remove them from the board and begin adding formers. Start with ply former A which is glued to the front of the box. Glue on one set of B, D, and F formers to form the rear edge of the cowl. Cut out another set of B, D, and F formers and sand a quarter-round surface on their curved edges. Add these right behind the first set. Formers C, E, 0, and H can now be added. Bend the landing gear wire and attach it with epoxy right in front of H, making sure it's firmly adhered to the bottom longeron and the upright above H.

Add the side and bottom stringers next, tapering them as needed before gluing them to the body. (The top stringers go on after the wing is attached.) Cover the cowl from A to B, D, F with 1/32-inch sheeting and add the 1/4-inch sheeting ring in front of A. Sand the cowl to shape. Using stiff paper (bond stationery is usually good for this), cover from the cowl back to the windshield former C, and to the stringers on the sides and bottom. Add balsa fairing strips to the landing gear wire with epoxy, using plastic balsa to fill out the shape near the wheels.

Make up the nose plug as shown. The notch on one corner insures that the plug will always fit on the same way. Bendable soda straws have a V2-inch long section that looks like cylinder fins. Cut seven half cylinders, then space them around the 1/4- inch sheeting crankcase..."

    see Wikipedia | search Outerzone


    ScaleType: This (oz9960) 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_Airmaster
    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.
