About this Plan

Yorkshire Pudding. Lightweight F/F rubber by J. Owen, from Model Aircraft September 1946.

Quote: "I built and lost three of these machines, at the cost of only 1oz of rubber. The average performance, using a hardwood airscrew, is around 90 - 120 sec, but due to its slow flat glide the 'Yorkshire Pudding' can take advantage of even the slightest lift in the air. Two of these models have held the Blackpool and Fylde MAS Open Rubber record, the first being a flight of 6min 43.3 sec OOS the model last being seen at an altitude of about 1,500 ft. The second machine, flown by Mrs Bentley, flew out of sight after 9 min 18 sec, but was actually seen to land six miles away 1-1/2 hours later.

Fuselage: The fuselage is built in the usual way, with all longerons and spacers 3/32 square medium hard balsa. The parasol wing mounting uprights are made from 20 swg piano-wire, bound and cemented to the spacers and longerons, as shown on the plan. Two 1/16 round bamboo runners form the wing platform. The single-leg undercarriage is made from a length of 18 swg wire, bound and cemented to a bottom longeron and spacer.

The Wing: This is built in four pieces and then joined together. The dihedral breaks should be braced with 1 mm ply. The leading and trailing edges are from 1/4 x 3/16 and 1/2 x 1/8 medium balsa respectively, and all ribs are cut from 1/32 medium hard sheet balsa and spaced as ihown. The tips are made from 1/16 square birch steamed to shape..."

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.
