About this Plan

Loening C-2 Air Yacht. Loening Keystone. Scale amphibious airliner model.

Direct submission to Outerzone.

Update 29/07/2015: Have re-scaled this plan now to something closer to the quoted fullsize of 49in wingspan, thanks to Pit for help with this. It is an old plan, and has not travelled well, I would recommend extreme caution if trying to use this one to actually build with.

Update 14/10/2019: Added article, thanks to RFJ.

Quote: "How to Build a Loening Amphibian. Here's Something Worth Building! A Flying Model of This Famous Air Yacht!

A GREAT number of our readers have been asking why amphibian plans are impossible to obtain. They told us that no manufacturer in the entire country had them - that they were told that amphibian models could not be made to fly - that if built, they would cost too much and a thousand other similar excuses.

That was just the kind of incentive MODEL AIRPLANE NEWS likes, and efforts were made to disprove the pessimists' wails. It was a job, we admit, but the finished product proves well worth the effort. It will fly, costs no more than the average scale model and looks like the real thing.

In its construction, we found that it was necessary to depart from the exact measurements of the Loening in a few places and add a four-bladed propeller, instead of the three, but apart from these minor changes, it is true to form.

Construction Details of Pontoon or Hull: In constructing the pontoon take a sheet of 1/16 x 6 x 36 in balsa and cut out formers B-1 to B-6 by tracing them from the drawings as shown in drawing 15. All these formers must be shaped to fit drawings, which are full size. The edges are then nicked as shown to fit the connecting spars and cross sections.

The next step is to take your 4 x 3 x 1 in block and shape out the 'bumper' or front end of the hull of pontoon. The 'bumper' A.B is then placed into position as shown in drawing 1, with ambroid, notches being cut to fit ends of longerons..."

Supplementary file notes



Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz6900) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Loening_C-2
    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.

* 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.


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.
