Note 24 — Chapter V

Note.—Since the above was written some really remarkable flights have been obtained with a 1 oz. model having two screws, one in front and the other behind. Equally good flights have also been obtained with the two propellers behind, one revolving in the immediate rear of the other. Flying, of course, with the wind, weight is of paramount importance in these little models, and in both these cases the "single stick" can be made use of. See also ch. iv., § 28.
