About this Plan

Seraph. A2 towline glider model.

Quote: "The Seraph is the latest in a series of long-moment A/2's and, although the designer states that it just falls short of a still air maximum from a 164 ft line, its performance in the preliminary 1954 eliminator suggests that the design will be well among the top dozen in the finals.

The layout follows the almost standard pod and boom approach, but additional strength is gained by running the boom right through to the nose-block and building the pod round it to obtain the necessary cross-section.

Construction starts with cutting out the sheet parts for the fuselage and gently steaming the bottom panel to a slight curve from F7 forwards. Secure the towhook in place and add formers 3, 4, 7, 8 and 11 to 21 inclusive. The auto-rudder line is threaded through and the DT hook cemented in position before adding the sides and top of the basic stick.

After fitting the side pieces P3, add the pod formers, the sheeting P1 and P2, and the rear wing peg. Cut the pod sides from 1/16 in sheet, chamfering the rear edges and fit in place, steaming to the gentle curve if necessary. Complete the remainder of the structure and sand smooth..."

User comments

Did anyone notice the plan shows square wing tips and the photo shows elliptical wing tips?

Fair point. Have switched that photo to more_pics 003. The Article says: "Heading view shows Peter Allaker's variation with rounded tips".

Notes

* 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.

Scaling

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.
