8 Ball - Free flight power model. 8 Ball from Model Airplane News issue 04-49.
Quote: - "EIGHT BALL. Class A free flight. Model is large enough for small Class B engines.
Wingspan 54in. Area 306 sq in. Engine .19 to .23. Weight 20oz. By RAY R. SCHOFIELD. Don't let the name fool you! The Eight Ball has a high performance and is a stable, consistent flyer. Although designed exclusively for Class A free flight events the model is large enough for small Class B engines. Eight Ball was developed from a series of model airplane designs. The better points of several earlier designs are incorporated in this model to maintain a more efficient and stable principle of design and construction, thus making it a good contender in any A or B event. Much effort and planning was put into the development of this model... The model has a very fast climb at about 70° to the horizontal and maintains this angle constantly with no dips or momentary stalls. Because of the high lifting stabilizer the model has a quick recovery to a horizontal glide, and the glide is smooth and slow. The ship does more than just glide it shows definite soaring tendencies and will ride the weakest thermals. On its seventh test flight, Eight Ball soared for more than an hour with only a 12 second engine run and landed in Great Salt Lake, more than four miles from the point of takeoff."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
