| Contd. -3- instead of 280 H.P. which is our latest output from this engine. There is more risk, I think, of our being told to slow down if we were manufacturing Eagles than if we were manufacturing Falcons. I do not believe the Air Board have yet got a good engine of about 250 HP which is free from Vibration, as is the case with all the 8 cylinders engines. We understand the geared Hispano is not yet a success. These are my impressions, which may not be correct. R.{Sir Henry Royce} | ||
