Default Free Plans and Design Aids Links

This thread replaces the previous sticky threads and puts all the information into one place. To keep it simple, quick to access and uncluttered it is locked against replying. If you have a question about any of the information please start a new discussion thread with your question.

If you find that a link is not working or find some new resource that is worthy of being included please PM the information to BMatthews or Da_Rock and we will follow up.

Links in this post were tested on Dec 20, 2009. Please PM as directed above if you find any that are not working.

Links to Free Plans-

http://plans.am.free.fr/ Site is in french but it won't be hard to figure out ( the best spitfire plans!!!)

http://www.nefkom.net/elektroflug/download_e.htm - A page of links to other sites. Mostly free flight sport and scale but perhaps some could be used for conversions or scaled.

http://www.hobbys.com.br/plantas_zipadas.htm (spanish) - A collection of the same plans as found on http://plans.rcmodell.hu/ . And maybe a new one or two?

http://plans.rcmodell.hu/ - Joe's Airplane Model Plans page. Lots of good stuff for everyone from small to big and trainers to scale.

http://www.theplanpage.com - Old historical model plans. Mostly rubber and gas free flight. Many would be good for electric conversions.

http://www.mat.uc.pt/~pedro/aeromodelismo/Planos.html (spanish)

http://meltingpot.fortunecity.com/li...os/planos.html (spanish) The site has the plans split into categories. It's easy to figure out where to go by just looking or trying out the options.

http://www.e-aeromodelismo.com.ar/Planos/Planos.htm (spanish) - a wide variety of nice plans. Some familiar and others unique to Europe. Split into categories. Everything from small free flight to big RC scale.

http://corsair.flugmodellbau.de/file...an/Bauplan.htm (german) another site that looks like it copied all the files from Joe's. But like many there may be a few new things from the locals.

http://my.pclink.com/~dfritzke/ - An eclectic collection of nostalgia RC plans mixed in with the odd bit of control line and free flight. It's an ever changing melange so drop by often and pickup anything you take a fancy to and save it since it may not be there the next time. Jr Falcon anyone?

http://www.tdmsoftware.com/majewski/...anrequest.html - a few plans from other sources re-done in CAD. You need to tell him a little about yourself to get the plan.

http://www.balsadust.net/thomas.vogel/Plans/ - Start on the left by clicking on the RC tag and follow through to get to the category you want. For the most part it seems to be another copy of the material I originally saw on Joe's site.

http://www.profili2.com/eng/default_plans.htm - a great collection. Some will be familiar from other sites but there's also a lot of unique stuff. Not organized by category so just wade through. MANY files to look at. There are thumbnails though so you don't need to download the file to see what it is.

http://www.parkjets.com - It's a busy webpage. The link to the free depron jet plans is about half way down the page on the left.

www.RippinFoamies.com - some nice indoor and outdoor depron foamies.

http://www.pldaniels.com/flying/index.html?page=plans - a couple of originals the site owner is sharing. Smaller sport designs.

http://www.willingtons.com/mymac/Plans_Download.htm - Some more copies of the stuff from Joe's site but with a good smattering of plans I have not seen anywhere else.

http://smoothair.rchomepage.com/plans.htm - Some interesting rubber scale models that may be useful as a basis for RC combat plans or light electric conversions.

http://agert.homelinux.org/~fredrik/flyg/ritningar - another appearance of the regulars along with a few that look to be from somewhere else. Well worth checking out.

http://plans.aerofred.com - a pretty good site but requires registration to gain entry. It's well worth it though if you're a planaholic. A lot of the usual common stuff but a lot of plans not seen elsewhere

http://ironelephant.blogspot.com/ - omostly old timer scale rubber models but one gas Great Lakes. The rubber models would be good for scaling into lightweight electrics or for the outlines.

http://borgpics.ulmb.com/Files/RC%20Plans/index.html - a few different options along with things like field boxes, benches, test stands, etc.

http://www.starcadplans.net/ - One of the oldest plans sites out there. He now requires registration to gain entry but StarCAD has some plans you won't find elsewhere. Worth the effort.

WARNING- This site requires registration http://freercplans.com/ - I didn't register but it seems to have a good variety of plans avaiable.

http://www.onerateads.com/RC-520.htm - A page of links. No real plans but there's some CAD building blocks that may be useful and links to a lot of other interesting stuff.

http://cineastv.forumeiros.com/banco...a-mil-t706.htm It's in Portuguese or Spanish but it's pretty simple to figure out what to do. Some familiar from above and some new.

http://aviationshoppe.com/airplane_p...ls.php?file=17 Lots of CAD files instead of simply images. - added 2012/03/27

http://www.mnbigbirds.com/Andersen%20Plans.htm Dave Anderson has graciously posted his plans for free for a lot of superb big scale jobs. -added 2013/08/30

An nice 2m span Turbo Porter plan by our own member Bo Denmark- EDITED 26-08-20 Original link is dead. But the plan is available at Aerofred. It is the first design on the page this link takes you to.. https://aerofred.com/search.php?sear...20PC6%20Porter

A site with a lot of vintage Free Flight sport and scale models that would adapt very neatly to RC electric power. Up over 5000 plans of all types at this point. www.outerzone.co.uk

NEW SITE added Jan 2016. A site with a number of medium to larger "cut and fold" scale designs made from foam board and possibly adaptable to Depron. If scaled down smaller copies in dollar store foam board could be done as well. http://rcfbaircraft.my-free.website/

Full size aircraft 3views and drawings-



http://www.seawings.co.uk/planspage.htm - Some nice drawings of all flying boats and seaplanes. Good stuff!

http://www.the-blueprints.com/blueprints/ - This site has a number of bitmaps available for viewing at reduced size or you can become a member and download the full resolution drawings. The 3views for aircraft are all just simple 3 views for the ones I checked out but if you're casually looking for a new subject to model it's a good first glance at what a lot of oddball aircraft look like. In particular they have a very good collection of WW1 drawings.

Printing assistance software options-

http://www.blackflight.com/ - Tileprint

Covert deflection angle to inches or inches to angle- http://www.aeroperfect.com/degree.html
Downloadable spreadsheet utility file.

Page of downloadable spreadsheets for calculating a lot of aspects. While these are said to be glider specific they should work fine for power models too. Included are two flying wing specific items. http://www.tailwindgliders.com/Files.html#Articles

XFLR5 is an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers. This package includes the original X-Foil. http://xflr5.sourceforge.net/xflr5.htm
