About this Plan
Cougar. Control line stunt model. Wingspan 54 in, wing area 555 sq in. For .19 to .35 engines.
Direct submission to Outerzone.
Quote: "I had a set of plans scanned for an old Midwest kit of a Cougar control line stunt plane of 54" span... Although Oz has the Panther plan, I have not found the Cougar plan anywhere. Thanks,
Mike Foster"
Update 12/10/2025: Added traced ribs, thanks to MikeFoster.
Quote: "Please find 3 pages attached showing the rib patterns for the Midwest Cougar (oz16316).
I poked out the die cut wing ribs from my over 50 year old unmolested kit of the Midwest Cougar oz16316 and traced them as accurately as I could.
One day I will have to build this to replace the one I had in 1973 - 4! Regards, Mike Foster"

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

Thanks for the Cougar plan, Mike. I built the Kenhi kit around 1955 or so. I don't get where they think a .19 will pull it. Maybe get it off the ground a few inches. Mine was built pretty light but my Fox .35 couldn't keep the lines from slackening in a wingover.-Dave (DPlumpe)

Designed by Hi Johnson and originally kitted by KenHi Model Products (Ken Adams-Hi Johnson).
Hi J. realized that some real aircraft airfoils like Lock P-38 worked in the Reynolds numbers range of stunt models aircraft and designed it's own airfoil. After several changes in his companies the model was kitted by Midwest.

New aerodynamically, new constructively and designed to give the modeler superior performance under all conditions. The photograph, seen above, will readily show you that this plane is absolutely the newest design on the market. Super Airfoils - the HJ04512, at the root tapering down to HJ04006 at the tip. Profile drag and weight are held to a minimum. For a decided thrill, to challenge your ability, try the Kenhi Cougar.

All is fair in love, war and model airplane kit advertising

Mine flew OK with an ancient FOX 40 Rocket - that is when you finally got it started! If I were to build another I would use either an OS 40FP-S or a Supertigre 35 Stunt both of which I already have. Undoubtedly other good engines would work but I would never pick a .19!

Has anyone have the root and tip rib profile for the Cougar? the plan shows the root but not the tip rib.

Tony-
Try scaling up the ribs shown in the "Die Cut Reference Sheet" section at the lower left. On a lot of kits the layout drawings in instruction manuals are pretty accurate.

On the plan there is a die cut reference diagram with all the parts, someone can enlarge it.
On Model Aviation there is an intersting rc conversion.

Notes
* 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.
Scaling
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.
