About this Plan

Hyphen 500. Free flight power contest model for engines up to 3.5 cc.

Quote: "A famous local design. Bill Evans was a famous designer in Adelaide after the war and in the early 1950s. He produced a magazine 'Australian Model Hobbies', ran a model shop, produced numerous kits under the 'Aristocrat' name and produced model engines in competition with Gordon Burford.

As we have said, in 1950, Gordon decided to produce a 2.5 cc diesel - the Sabre 250. At that time Bill was the distributor of Gordon's engines so he set about designing a model for this new power unit that he would introduce as one of his kits. The model was the 'Hyphen 500', a free-flight contest model for engines up to 3.5cc - the 500 refers to the 500 square inches wing area. The Australian rules demanded that the model weighed eight ounces per cubic centimetre of capacity, thus the model would weigh 20 ounces with a 2.5 cc engine and therefore needed to be a reasonable size.

I found the fuselage construction of 'Hyphen 500' very interesting. It was 1/2 in balsa sheet with 1/8 in sheet reinforcement under the wing. This made for rapid building and the model was popular over here. I used this construction on my 'Scramble' designs for the Mills .75 and it proved very rugged. This design may interest the free flight fraternity but is less likely to inspire our 'wireless' readers - its profile fuselage makes it rather difficult to fit R/C!"

* 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.
