Shoestring - Radio control sport scale model. 1/4 pylon racer.
Quote: "THERE IS a chap in our club (John Ralph) who persistently disturbs the peace and quiet of our otherwise rather sedate flying field with hairy, snarling, brightly coloured, monsters that leave the rest of us as though we were watching a tennis match in the sky. Not content with this, he is always managing to persuade one or other of us to join him in his madness - and this time it was my turn to succumb. Reports from America of the smaller pylon racing classes aroused my interest, particularly the '1/4-racers' for .15 sized engines. These, although smaller than the two usual classes, seemed to me to be not too small to get some of the less modern, not-so-mini radio gear into! To tell the truth, I couldn't understand the main centre of interest, so far at anyrate, being in the .049 powered class. However, after listening to comments made by the racing fraternity at some of the meetings, I realised that things could soon get out of hand with 1/4-racers, because of the very potent .15's that are available now, if there were no restrictions...
I always did like that Shoestring of John's so having got all the gen, I scaled it and tailored it to fit the 1/4-racer formula. With the smaller model size, construction could be made simpler, too, and this is what I have done. In fact, as you'll see from the plan, the construction is about as simple as it can be. However, just to be certain, we'll go over the main points..."

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.
