About this Plan
Coin-Foo. 1/2A radio control sport model.
Quote: "Does this little 1/2A sport flyer look like a Counter-Insurgency fighter to you? Me niether. But it sure looks like fun. Coin Foo, by Dean Swift.
The Coin-Foo does have three good things going for it. Good Thing No. 1: This little turkey is dead simple to build. Consequently, construction time is minimal -and no one seems to have 'enough time' anymore. So if you just tried cleaning the gunk off your 1/2A foam ARF with gasoline and all you have to show for it is an extra radio and a handful of mush - don't despair. Coin-Foo is closer than you think.
Good Thing No. 2: Coin-Foo expands your available flying time. A normal evening's R/C flying goes something like this - drag the 8 lb beast out of the basement. Stuff assorted pieces in your car. Drive 10 miles to the field and assemble assorted pieces. Fly two quick flights. The sun sets. Reversing the above procedure puts you back in the basement cleaning up the mess an hour later. Your children arein bed and the wife is glaring at you. At this time the moon sets.
With Coin-Foo you can wait till the sun sets, carry it out of the house in one piece, walk to the corner school yard and fly four or five times during the twilight. While walking home clean it with a quick swipe of your ever-present rag and hand glide it down the basement stairs. Now go sit on your old front porch and watch the moon rise.
Good Thing No. 3: The Coin-Foo performs well. With those large control surfaces set for minimum movement the response is gentle and stable. In fact, Coin-Foo will free-flight, as two local builders have proved by launching with the receiver switched off. If this happens to you don't think you're going to 'luck-out' with a simple crash, this bird re-quires running shoes to recover under switch-off flying conditions.
On the flip side of the coin, if loops, snaps, etc are your bag just move those devises in on the horns and have at it. Hang on!
Well, that's about the story on this little hummer. I have allowed myself to ramble on with the introduction as building instructions are short. For what it's worth, here is what I have to offer concerning construction.
Fuselage: A couple of items are worth pointing out, Notice the fuselage bottom from the trailing edge of the wing to the firewall is 1/16 in plywood. This lends itself to mounting equipment with scervotape better than 1/16 in sheet balsa, Also adds extra strength to the front end should you ever assault the ground. The landing gear is trapped between the recessed rear of the fuel tank and firewall if a reed-valve Cox engine is used. This is a quick and easy method of mounting engine, tank and landing gear, usually a time-consuming process on most R/Cs..."

User commentsBuilt from this plan in Feb 2014 [see more pics 004]. Very easy to build and flies a dream, used electric power instead of the .049

Here are a couple pictures of a Coin-Foo I built from your plans [see more pics 005, 006]. I remember this model from when the article first came out in MAN, I was 13 years old then. I built mine faithful to the plans, except for electric power. E-Flite Park 300 with 2S 1350mah. It's a great sport flier. Thanks to Dean for the design and Outerzone for hosting this great service to all of us who still like to cut balsa.

I built a Coin-Foo back in the early 80s using an Ace 36 inch constant chord foam wing. That little bird flew great. I could bring it in slow enough to actually catch it!

Hi Steve, Pictures of Coin Foo built from plan 5265 [more pics 007-011]. I live at 8500ft ASL, she performed great on a Rimfire 200 motor, battery 2s 500 7.5volts, 8x4 propeller. Total weight 14oz. Great park flyer. My first flight after 20 years, now I am retired in the mountains of Colombia enjoying this great hobby again. Thanks for providing us for a great source of plans for our projects.

* 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.
