Quote: "The Vega range was designed and built from the late 1980's through to the mid 1990's by John Harbone of Birmingham, England. His intent was to provide a range of engines for sport or scale flying that would be quiet and reliable. They were manufactured in small quantities from bar-stock until ill-health forced an end to the venture. The rights to all the designs were sold on with the intention that they continue in production, but sadly, this did not eventuate.

The initial models were all side-valve four-strokes. The range also included a .61, .25 and a horizontally opposed, alternate firing twin using the .25 cylinders to give .50 cu in total displacement. Towards the end of production, .61 and .91 cu in displacement over-head valve (OHV) prototypes were made although they did not reach production. All models are comparatively rare today, but they do appear occasionally as collectables.

Each model was offered in two versions. On type A, the carburettor and exhaust were oriented to the rear of the engine, while type B placed then on the side of the head. Company advertising stressed the enclosed valve gear, free from tappet adjustment, the compact size, 'solid' (bar-stock) construction, quiet running, and ability to idle for long periods with instant throttle response..."

* 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.
