CHAPTER XIII.

MODEL FLYING COMPETITIONS.

§ 1. From time to time flying competitions are arranged for model aeroplanes. Sometimes these competitions are entirely open, but more generally they are arranged by local clubs with both closed and open events.

No two programmes are probably exactly alike, but the following may be taken as fairly representative:—

1. Longest flight measured in a straight line (sometimes both with and against the wind).[48]

2. Stability (both longitudinal and transverse).
