i am just starting and it would be nice to have the build instructions if there is any.

Hallo Mary, hallo Steve, the restoration is finished. I think the Ultra Fly is more than 30 years old. Last Saturday was the first flight [more pics 003-005]. The model flies very well.

Hello, I am new to aeromodelling. Can you tell me where I can find the assembly instructions. Thanks for your help

This wouldn't be ideal for a beginner - it could be better if you started from a kit with all the necessary plans, parts and instructions.
However, if you want to learn from plans, a simpler design would be better and also read this book to get a better understanding of techniques (and the tools and equipment you will need

Hello Pierre, the Ultra Fly ist a very good model. It flies fine. Building from a kit is possible. But building the free flying elevater may cause problems. If you want to built a wooden glider from a plan, better try "Blue Phoenix", that is much easier and more stable! If it flies successfully you can try the "Ultra Fly" https://youtu.be/4OgVqD0p-hk you can see my "Ebay-Ultra Fly" flying...

* 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.
