There is another advantage which the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) type has as regard silence, and that is, the axle is less rigidly attached to the frame, so that vibrations and noises due to the axle gearing ought not to be carried to the frame and body as easily as in the case of the 40/50. In the Seagull(Experimental EAC.1 aka Export chassis, Phantom I engine) it is intended to follow the practice of the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) in all respects. The axle is just going to Derby this very week, the gearbox has been quite re-designed for "Servo", for four wheel brakes, and side change levers. It too is nearly ready - perhaps in 10 days hence it will be all complete. Some important and vital parts of the engine for Seagull(Experimental EAC.1 aka Export chassis, Phantom I engine) also leave WW. this week, so that Derby will be very busy in experimental produce.
