Spitfire Mk IX (oz12210)
About this Plan
Spitfire Mk IX. Radio control scale model WWII fighter, for electric power with geared 600 motor. Wingspan 49 in. Scale is 1/9.
Note the real point of this Oz listing is the CAD file. The PDF plan here is a 2-colour bitmap at 425 dpi, extracted from the CAD drawing. It is but a pale shadow of the original. Frankly, it is only here so you can get an idea what the CAD file looks like - if you want the real thing, download the CAD file.
Note for a redrawn version of this plan (shows brushless motor installation) see Spitfire Mk IX (oz12225).
Note photo of completed Spitfire IX model by GADMAC was found online at https://www.rcgroups.com/forums/showthread.php?130235-One-Excellent-S600-Spitfire-Plan%21%21/page9 which is an excellent build thread with 58 pages of discussion, hints, tips and photos.
This plan is available for download in CAD format.
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 (oz12210) 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/Supermarine_Spitfire
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.

User commentsA fine drawing from someone who knows his mettle, and a fine design from someone who knows how his model engineering :-) If one wants to avoid gray printing it's easy to convert all colours to black, print away and then close the file without saving changes.
That French site is from the time before large format scanners and the most practical format for larger size models was DXF or DWG. A good time for developing those CAD skills. There are still a few surviving places from the Triassic, one example is Dave Fritzke's own http://my.pclink.com/~dfritzke/, a well-known name here ;-)

This is a really nice design, lots of plywood so wondering about the weight :-). Does anyone know what is a 600 geared electric motor? Or has an example of one?

If you have a look at the modified alternate version of this plan by Won2Race here https://www.rcgroups.com/forums/sho... there is a drawing of a suggested modern brushless motor setup. He shows a 600W 3520 6 turn 840kV outrunner with a 3S 5.3 Ah lipo. Actually, that's such a good version (of this plan), it would make sense for us to add that as a separate entry over here on Oz.

I've built several models intended for different motors with good success. A model of this size would normally use a 40 size glow motor. The E-Flite site, https://www.horizonhobby.com/content/e-flite-rc has some good information on motor sizes. Some of their motors have numbers similar to glow engine sizes. The E-Flite 46 looks like a good match for the Spitfire. E-Flite will tell you what prop and battery to use, has worked well for me. Don't even consider a geared 600 motor, even if it's free. This model is fully covered with sheet balsa, so pick out some light balsa to control weight. Good balsa is not easy to get these days, I always order about three time what I need so I can pick the best, hobby shops have little choice. Be careful about the spinner, don't even consider a plastic version, will (not may) be badly out of balance, will ruin your bearings. Ask me how I know. Use APC electric props only. And of course there are the Three Rules of Electric Flite.
Keep it light.
Don't let it get too heavy.
It shouldn't weigh very much.
The immortal Spitfire has a reputation for having a too-small tail. I would increase the size of both surfaces, keeping the same shape. No one will notice. They fly beautifully, having flown several. They tend to nose over on landing, consider moving the gear forward a little. I said a little, not a helluva lot. Retracts may not be your best choice.

Hi Steve, thanks a ton! Exactly what I'm looking for! I agree with your assessment that those plans should be added, or replaced as it's 2020 and brushless motors are not a thing anymore on this scale :-). Only downside is most of these plans are in weird (non-metric) units ;-P, but it's one I'm willing to put with :-D.

* 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.
