About this Plan

Extra 300 90. Radio control sport-scale model for 90 power.

Discontinued kit from Carl Goldberg Models.

Quote: "If there's an aerobatic subject that can challenge the thrill of the Goldberg Ultimate, it’s this Extra 300! The Extra's generous moments, light wing loading and strong airframe make it an excellent airplane for the aerobatic pilot, whether he is learning his first maneuvers or is an unlimited class competition flyer. Yet with all its aerobatic potential, this is still a very well-behaved aircraft, making takeoffs and landings a breeze. And when it comes to engines, please note: bigger is not better. A good .60 will do an excellent job. A larger than recommended engine may overly stress your model, causing structural failure..."

* 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.
