Thank you for your terrific plans service & website. Attached is a photo of a Mercury Models Grebe glider built from your plans and print wood files [see model photo and more pics 003]. I printed off the print wood patterns first on my home PC and checked them against my old tattered original plansto find that the patterns were dead on accurate. When printing off the model plans I had to reduce themby 2% (set printer at 98%) to make them match the print wood. This could have been due to theage of the printer we used! The model came out at 10.6 oz. AUW, balanced and ready to fly with rudder and elevator controls, 4.8V, 750ma AAA size battery and a small 4 ch. 2.4 Ghz receiver and switch. The model is covered with Coverite "Microlite" plastic film. Not flown as yet but no issues are expected as the original one I had in the 60's flew great. This one I will not have to chase after! Thanks again

* 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.
