Duchess - Stunt biplane, for control line. Quote from article intro: - "Peter Miller concludes his feature on aerobatic control-line biplanes with plans for his well-developed DUCHESS a 'different' sportster for .25-.3S cu. in. motors.
IN SPITE of her name, the Duchess is no staid old dowager, but a very flighty young lady who can trace her ancestry back to 1961 - at that time I was serving with the R.A.F. in Aden where there was an extremely active model club. One of the models I built there was the Duchess Mk I which was quite acrobatic, though not outstanding. In 1968 came the Mk II version, which had a very brief life due to both lines breaking (moral - never borrow someone else's lines!). The biplane bug had by now bitten hard, and there followed a series of semi-scale and full stunt biplanes plus one or two true scale models with stunt potential, some of which were described in last month's article. The culmination of this was the Cavalier series which up till now has been the most popular design in the Sudhury M.F.C., some 15 of them having been built. I then decided to return to the Duchess design, with all the lessons that had since been learnt incorporated, so here is Duchess Mk III. The construction is very simple, and it is not proposed to go into the 'glue A to B' type instructions, but instead will deal with the points which are different from the normal monoplane. Due to the small size of the main components it should be possible to work on all of them on the building board at the same time, which means you will have no 'waiting time', and the model is very quick to build. The original took just 36 hours from start to finish."

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.
