Quote: "Proof of the old adage 'good things come in small packages' is here with the Simple Ultimate. Now you can enjoy the adrenaline pumping thrills of the super-popular Ultimate biplane in a small, quick to build version. Sturdy and light weight structure is achieved through the use of crisply cut lite ply and balsa. Put a .15 engine in the nose, load it up with four mini servos and a small battery pack and you'll be set for a day of thrills."
Quote: "The Simple Ultimate is designed for .15 sized engines, but .10 to .20 can be used. The full scale Ultimate was designed for aerobatics and so is the model. The Ultimate can do every trick in the book, and you will probably invent a few more as you fly it. The Ultimate will take off from a smooth runway. Hold in a little right rudder to keep it straight. Take it up, trim it out then wring it out."

* 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.
