About this Plan

Dornier Do X. Free flight scale model for electric power. Wingspan 42 in.

Note this is not a full size plan. This is also a low resolution plan. This plan is really just here as a marker for now, in the hope that a better quality scan will come along, over time. Also, to be honest, so we can show you SkyDome's great photos of his tiny electric FF version. Plus a link to some video.

Note main model pic (photo by Pat Daily, showing the original 42 inch Don Srull prototype in flight) was found online at https://www.rcgroups.com/forums/showthread.php?1320400-Dornier-DO-X

There is mention of the original 42 inch Dornier Do X model in this article online, see https://www.airspacemag.com/as-interview/modelers-tale-don-srull-interview-model-airplanes-180957297/

Quote: "It’s a hard choice, but my most memorable model experience was the Dornier Do-X. In 1988, when electric models were beginning to break out, electrics offered a new opportunity for multi-engine models. It was possible - but very difficult and risky - to use other motor types. Electric motors were much more reliable and consistent performers, so they were ideal for this use. A few twin-motor scale models worked well for me, so I decided to go the limit and build an old favorite - the Dornier Do-X, a 12-engine giant flying boat, built in 1929. To be honest, expectations for the model were not all that high, but the real Do-X had a fascinating history, and I liked its looks. To everyone’s surprise, the 42-inch free-flight model flew remarkably well on its first day out. It has had a charmed life. Even with homemade motors and early nickel-cadmium batteries, I flew it without serious damage for years and hundreds of flights. Eventually, I replaced the motors and batteries and added a small RC system. I still fly it occasionally today."

Quote: " Hi Mary; The Dornier-X's plan is not on Outerzone now. I got the plan from a friend, and he told me it can be download on the internet for free. Here is the free download link, so the plan may not have the  copyright now, I think you can share it on Outerzone, and put it at scale electric FF or RC. The link: http://www.hallmanstudio.com/DOX.Srull.pdf
I saw a video on youtube, which had been changed to rubber powered single propeller free flight model, and half the wingspan. So I decide to make a micro scale RC DO-X. The youtube link of the free flight model [by Tom Hallman]: https://www.youtube.com/watch?v=b22F7zucvZw

The one I made from this plan [pics 003-007] is about 1/3 scale, only 380mm wing span, and use two channel radio control (yaw by differential thrust of two motors). The motors are 614, and the model takeoff weight is about 29 grams. It is maybe the smallest RC dornier X in the world? (however it has only 2 motors, not 12 like the real one). Here is the video of my micro scale DO-X: https://www.bilibili.com/video/BV1Y5411W7GH

    ScaleType: This (oz12794) 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/Dornier_Do_X
    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.

User comments

Th Do.X as a model is naturally associated with gigantism so a 42in model is already an eyebrow raiser. Now a smaller re-scale model of that, all of its wingspan fitting under two handspans is definitely shrinking the envelope no doubt, and in sweet balsa and tissue too! Quite a feat! The only negative thing I can say is although it has two wings (shoehorning the stub wing in!) but no round engine - they're all square, the dozen of them! I sincerely hope it flies as well as it looks, 15in, 42in, whatever size you cut it.

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.
