Extra 260 (oz11252)
About this Plan
Extra 260. Radio control scale model. Wingspan 94in (238cm). Scale is 31%.
This plan is a free download from the Flying Giants forum thread: "31% Extra 260 - Building from scratch" dated 2008 by Rodrigo Maia at https://www.flyinggiants.com/forums/showthread.php?t=32191
That build thread is a great resource (all of the model pics here on this page were found there) with a detailed record of the designer's build process, and includes lots of great information along with more excellent pics.
Quote: "Extra 260 31%. Designed by: Rodrigo Mercê Maia. This is the package for the plans of this model aircraft. It's 94 inch span and intended for engines in the 50 to 85cc range. My protoype used a DA-50 and the final AUW ended up at about 19 lb.
The 'LaserCutParts' DXF file [see inside CAD zipfile] contains all the parts intended to be laser cut. You can then split the parts according to the needs of the laser cutter you will be using. The DXF units is milimeters. See also 'LaserPartsGuide' PDF, a 'printout' of the laser parts with labels explaining what wood type and the general group of the parts. You can print it if you want, but it's there more for on-screen reference.
The 'PartsFullSize' PDF contains all the laser cut parts split into separate sheets (varying in size) and printed with 1:1 scale. These files are to be used in case you wish to manually cut the parts. The fuselage parts are all intended to be cut from 1/8 in Lite Ply.
The plans themselves [main planfile, 3 sheets] don't contain any labels, but I hope all the pictures posted on the build thread in the FlyingGiants site help to understand the build. You can also post any questions you have regarding the build, as well get more info about it there. The link is:
Best regards, Rodrigo"

ScaleType: This (oz11252) 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/Extra_EA-260
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.
