About this Plan

Aeronca C-3. Radio control scale model, for .099 engines. Wingspan 54 in. Scale is 1/8.

Direct submission to Outerzone.

Planfile includes build instructions.

Quote: "Building and Flying Instructions: The first step before starting actual construction is to study the plan and kit contents thoroughly. Remove all die-cut parts from the sheets, and group the materials to be used for the wing, tail surfaces and fuselage. The time so spent will make the assembly that much easier. Decide at this time whether you will build the model as a Radio Control design, Free-Flight or Controline.

Wing Construction: Start with the wing surfaces. Select the spar material, and layout the 1/8 sq, 1/8 x 1/4 and 1/16 x 1/8 bottom spars on the plan. You will note the 1/16 x 1/8 spars join into die-cut W-17. The other spars must be spliced where they change angle at rib W-11. Block spars up 3/32 off plan at rib W712, and install gusset W-13 to reinforce the spar butt joint etc. Note the spars must be blocked up 3/8 off plan at the tip. Bevel spars to meet as detailed.

Cement the plywood die-cut gussets together, and then to the spars as indicated. Follow next by installing the rib units W-1 through W-12. After all ribs are positioned, the top spars are installed in like manner, followed by the leading edge, which is 1/4" sq. with a simple diagonal splice near the tip. Pre-coat end grain etc.

The ailerons are very easy to assemble, but unlike the main panels, you will do best to cement the rib units (prefixed with WA-1 etc.) directly to the sheeting provided for the aileron bottom camber. The leading edge, WA-5 is die-cut. Short lengths of .040 wire should be cemented into the ailerons to serve as adjustable yet firm mounts.

After removing the assembled panel from the plan, construct the other panel in like manner, blocking up as necessary to permit the plywood gussets to lay flat on the plan. Install W-14, W-15 AND W-16 in place, for these serve to reinforce the wire hooks for the rigging or flying wires. Cross marks appear just outboard of the W-7 rib where the thread or wires under the wing terminate. Cover the wing areas indicated with 1/16 sheet, top and bottom. Capstrip ribs in like manner. The airfoil cross-sections will clarify the structure. A scrap brace may be used at the wing center if desired. Solder the 1/16 wire rigging mount to the 3/32 wire at the wing center leading edge...

    ScaleType: This (oz14032) 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/Aeronca_C-3
    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.

Greetings! The sup file added with patterns is incorrectly sized. Printwood sheets about 18ΒΌ" wide, and shown as much larger in the file.

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.
