About this Plan

3-D F4F Wildkatz. Proflie semi scale model for .40 - .46 power.

Direct submission to Outerzone.

Update 25/9/2023: Added alternate plan at correct fullsize, thanks to JanNovick. This is scaled correctly at wingspan 48.75 in. This is not vector format, it's a bitmap at 400 dpi.

Update 26/9/2023: Replaced this main planfile with a corrected version (still in vector format) now at correct 48.75 in wingspan, thanks to hjsaxe.

Supplementary file notes

Alternate plan, fullsize bitmap.
Previous scan version.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Hi, Cant see wing ribs. Will author upload?

Rib temples are on plan
Terry - 04/07/2021
No rib templates on the plan. Anybody have them?
Jeff Worsham - 22/09/2023
The root rib and wing tip rib are shown on the plan. It should be possible to produce a full set of wing ribs using the sandwich method.

Turns out this plan is scaled incorrectly, should be wingspan 48-3/4 in, but is about 36 inch. Thanks to binkhouse for pointing this out. This is a vector format plan, so beyond my skills to edit. Can anyone out there take this file and rescale it to the correct 48.75? Thanks

you could use printing scale 137%

You can do like I have done several times, IMPORT the PDF file into GIMP, then scale it to whatever percent you want, and EXPORT it as a PDF. Then you won't have to explain to whoever does your printing how you want it enlarged, not an easy task. Believe me, anything that differs from their usual routine is asking for trouble. Ask me how I know. Your new plan will be bigger than 36" in both dimensions, which may also be a problem. The printer I use will only print 36" width, length doesn't matter, paper comes off a roll. If you try to print a sheet that's too large, it will just scale it to fit the paper. GIMP will fix that too. You can crop off the left side and save it as a new file, then do the same for the right side, with a little overlap in the center, then tape it all together. If you ask them to do it for you, ain't gonna happen. You can use the MEASURE feature in your PDF reader (I use Foxit Reader) to check your new PDF's. GIMP ain't easy, but it WILL do it. Best part, GIMP is free. I know I'm cheap but I don't care.

Ok, have added a rescaled alternate plan (in bitmap format) thanks to JanNovick. Which is good, and helpful, but of course now the file is no longer in vector format. What I'd really like is to have the vector file re-sized to correct fullsize at 48.75 in, and kept in vector format. Anyone?
SteveWMD - 25/09/2023
Doug, that's a long way to Tipperary but maybe I have a shortcut. What I do is print into a PDF file. It's easy, in your PDF print screen instead of using your designated printer, use 'Microsoft Print to PDF'.
Is that it? Sorry, no, there's a problem which is MS Print to PDF can't print sizes above above ISO A3.
Is there a workaround? Sure there is. You must download a 2nd PDF reader, Foxit Reader at foxit.com . This is an alternative to Adobe Reader but more on this soon.
The logic in this is that when you install this Foxit Reader you also install another PDF printer that is assumed by Adobe Reader as another PDF printer. The advantage this brings is that its paper format range allows sizes larger than A3, which is what we wanted.
So, the procedure boils down to:
- Install Foxit Reader.
- Open Adobe Reader with your plan and select Foxit Reader as your printer.
- Apply your scale factor
- Go to Printer Properties and select the adequate paper size for your plan.
- Click Print and Bob's your uncle and Fanny’s your aunt :))
I may be skipping some minor steps but I trust the audience will be able to fill in any blanks. A question remains: If I'm downloading another reader to solve the problem, why can't I use this instead and drop Adobe Reader entirely? Well, you can, but to be honest I find Ad.Rea. much easier to use, Foxit Reader is a pain in the gluteal region to configure and use.

Another way to rescale vector format pdf`s:
Open the pdf in inkscape (free program), group the complete plan, scale it 136,5% (gives me a ws of 48,79") adjust document size to fit plan, then ungroup to have access to individual parts.
I will upload resized vector plan.

That sounds excellent. I actually have Inkscape on my machine here somewhere, I really must learn how to use it. 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.
