Half Tone - 38in span RC sport model for 0.8cc motors, designed by Dave Platt.
Quote: - "Just once in a while every modeller builds a model which by its sheer simplicity, lack of fuss and expense, and real flyability, proves that sometimes the simple things of life are best. After a whole series of R/C models, some with fancy engines and exotic R/C gear, of which few flew really well and even less justified their time and cost, this little model was made in an honest attempt to return to essentials. The reasoning went like this - if I could make a model for a 0.8 c.c. engine (Baby Bee) to carry a Unitone Rx and compound escapement, which would fly in a reasonable wind, then what more could I need? The old adage 'Simplicate and add more lightness' was borne in mind in the design stage, with the happy result that the little job was completed in a week - without burning any midnight oil. Further, the cost was so low as to be laughable and the designed all-up weight of 20 oz. was exactly met. No grey hairs here! The following construction notes are just as brief as the model warrants, only the points of special importance being mentioned..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
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.
