MARCH 1, 1923 rate it at 18 at that speed, and "the curve continues to go up, although we take it that 2,500 is the normal maximum at which the engine should be run for any length of time. The compression ratio is 4 • 5 to 1, and the brake mean effective pressure about 90 lbs./sq. in. We understand that a small production batch of these engines is now being put through the shops at Filton, so that the " Cherub " should soon be available commercially. That the engine really in this case does "fill a long-felt want " cannot be doubted. It is of sufficient power to fly a lightly-loaded machine at quite a good turn of speed. A rough estimate indicates that it should be possible to build a single-seater machine which would have a maximum speed of about 60 m.p.h., with the engine developing 18 h.p., and a landing speed of just over 30 m.p.h. The minimum power required should not be more than about 10 h.p., so that a good reserve should be available, both for getting off and for flying extremely cheaply at cruising speed. A smaller engine would be sufficient for just flying around in the neighbourhood of an aerodrome, but with the " Cherub " cross-country flights should be well within the limits of practical politics. In this connection, it is interesting to refer to the small Udet two-seater described in this issue of FLIGHT. That machine is fitted with a Haacke two-cylinder opposed engine of 35 h.p., so that the power expenditure per occupant is the same as would be that of a single-seater with the " Cherub " engine. With two up the Udet has a speed of 95 m.p.h. Its wing loading is, however, rather high, about 9-5 lbs./sq. ft., and the landing speed is probably greater than we should choose for a machine of this type. But even with a lower wing loadipg the top speed should be reasonably good, while the landing speed and get-off should be such as to enable a machine to be landed in and taken out of almost any reasonably sized field. At the moment of writing we have no information relating to the price at which it is intended to market the Bristol " Cherub." We have heard the figure £15 mentioned, but do not know if this represents the actual price. It appears probable that it will be a matter of some difficulty finally to decide upon a price until the first batch of engines has been completed, when data of production costs should be available. Readers are advised to apply to the Bristol Aeroplane Co., Ltd., Filton, Bristol, for any further particulars desired. The Royal &ero CLcz of the United Khxgdoi OFFICIAL /S0TICE.5 TO ME.MBER5 RACING COMMITTEE * A MEETING of the Racing Committee was held on Wednesday, 21st February, 1923, when there were present :—-Major- General Sir WT.

Schneider International Seaplane Race.—The Com- mittee had before them proposals to hold the Race at Eastbourne, Brighton, Weymouth, Cowes and Torquay. After hearing the report from the Special Committee on the facilities available at each of these places, it was unanimously decided to select Cowes, and to hold the Race on Friday, the 28th September, 1923. Mr. S. E. Saunders of Cowes has kindly placed at the disposal of the Royal Aero Club his Solent Works, which provide ample accommodation for housing all the competing machines. The course, although not finally settled, will include turning points at Cowes, Calshot and Southsea.
