Half Tone (oz5673)

About this Plan

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.

Wing. Build one half, then prop this up at correct dihedral (don't increase the angle) and build the other half on to it. Use medium to hard balsa for the LE and spars, soft or very light for the TE and ribs..."
