Spitfire Mk IX (oz12225)
About this Plan
Spitfire Mk IX. Radio control scale model WWII fighter, for electric power. Wingspan 49 in. Scale is 1/9.
This plan is a redrawn version of the Dave Philpott Spitfire Mk IX (oz12210) design. The original plan showed electric power using a geared 600 motor.
This here is a later version, redrawn by Won2Race, posted up on RCGroups in 2010 (see datafile link). This plan includes 2 further sheets, showing (1) full second wing layout and (2) alternative brushless motor installation with 600W outrunner and lipo battery. There are other minor detail changes that show radio installation, retract air tank, etc.
Note this plan is in PDFvector fomat. We have no CAD version [edit: Fixed now. See below]. For the original Dave Philpotts CAD file, see Spitfire Mk IX (oz12210)
Update 29/05/2020: Added zipfile with CAD version of this plan, thanks to Miguel.
Quote: "Good Morning M&S, Please find attached the CAD files for the above. No difficulties were encountered in converting from the the PDF vector file posted, zamzar.com having been used. Formally speaking, to be entirely correct the drawing elements ought to have been segregated by colours, each colour corresponding to a separate layer, and all 5 sheets should be brought together under one single file, internally separated into five printing layouts. However looking out my window I can't see any mob of revolting peasants brandishing pitchforks and torches, so I'll leave the matter be :-) Kind Regards, Miguel"
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 (oz12225) 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 commentsHi Steve. This may be excessively picky bit I've looked at the recently posted plans for Dave Philpotts' Spitfire Mk IX. [see also Spitfire Mk IX oz 12210 oz535] I'm a control line flyer and not directly involved in scale and I don't know the detailed rules for scale anywhere, however, there is a small error in the profile on both versions of the plans. The cover over the fuel tank immediately in front of the cockpit is straight in profile and slopes down about 0.5". At 1:9 scale, this is about 0.055" so it is visible. The cowl over the engine then curves up quite quickly and completely flat from F4 to F5 is probably an acceptable variation. It is what I would do - and probably will do - if I ever get to building a semi-scale Spitfire at that sort of size, using a design philosophy like that employed by Noel Stephenson all those years ago.

Thanks Geoff, here at Oz we just put the plans up as we find them, for the archive. The 'mistakes' are interesting and part of the history. Anyone who wants to make this a truly scale model will have their own very particular opinions about many details :-)

* 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.
