Spartan. Control line stunt model.
Quote: "SPARTAN. An attractive beginner's stunter by AJ DORRELL who designed it for the pupil members of his school model club which he writes about next month.
IT has been said that stunt flyers are born and not made. I am not prepared to argue that yet because, although my present standard of flying might have won the Gold Trophy in 1948, I have a long way to go before I can manage the current schedule.
I have been modelling ever since I can remember, but my first venture into aeromodelling, C/L. at that, was with a super scale biplane fighter. Do I need to say more. When two more models, at least they were not super-scale, had found a final resting place in the scrap box, I could at least fly round and round.
However, honour was not satisfied, I had seen a stunt flyer in action and the realism of his beautifully made stunter exerted the greatest appeal to my ideas of model making.
Much practical work with a series of boxy and very functional stunters eventually resolved itself into a successful design formula. This was embodied in the Spartan series, which has been fully proven through many hefty prangs in inexperienced hands.
The drawings are for the Mk III version which has been refined for appearance and greater aerodynamic efficiency, but still retains the rugged characteristics and strength of the earlier versions. Build it simpler if you wish, but retain all the strengthening materials such as spruce, ply and nylon covering. It will pay in the long run.
The detachable wing was chosen for two reasons. When a fixed wing model crashes the wings tend to keep moving forward and shear oft either side of the fuselage. On this model the rubber bands, which should be tightly stretched, give way first and these can easily be replaced. Secondly, if one of the two major components does break, it is a comparatively simple matter to replace it entirely, if necessary, whereas a fixed wing model may be a complete write-off.
Construction. There is sufficient information on the plan to enable anyone who has built at least one model to need no further instruction. However, I am going into the construction in some detail in order to pass on some hints and tips that I have found useful. Also, in as many instances as possible, the reason why these methods have been used. This information should be found useful then in the construction of other models.
Wing. The two wing ribs shown on the plan are not actual ribs, the larger of the two is a little greater in size than the largest rib needed and the smaller is a little reduced all round from the smallest actual rib..."

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.
