| BJ. from R.{Sir Henry Royce} c. to Wor.{Arthur Wormald - General Works Manager} BY.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} X7410 Rl/M1.10.27. (1) RR.F. ENGINES. X.4657 X.7410 (2) PHANTOM SPORTS MODEL. X.2810 X.7770 X.8774 I was very sorry to hear you were not well, and missed you at the lunch very much. Fairey was very pleased generally both with the results and that we had given him all we promised, and the outstanding difficulties were looked upon as inevitable, but he was anxious not to lose any speed in meeting the additional cooling requirements. We believe we have the matter well in hand, though we cannot promise to achieve the results without giving a little. Fairey mentioned that the machine had done 173 MPH. at 6000 ft., apparently a very excellent result considering the altitude. The engines are going on at the Works with, I believe, satisfaction to the testers. Regarding the Phantom Sports model, I think you can set your mind at rest that we do not intend to make any change to the chassis other than those which will be used in the std. chassis. We feel sure that most of the modifications will improve the performance of both the sports chassis and the ordinary chassis, and in addition, will be lighter, simpler, and less costly. You will see therefore there will not be two chassis and everything will be of benefit except the cost of changing patterns and tools. We are also looking upon it as a stepping stone to EAC.7. which chassis was here this week, and I was impressed with the wonderfully good riding in the rear portion of this car, our next move being to make the front of it better by more flexible springs, and improve its appearance by lowering it 1" nearer the ground to match the back. Hs.{Lord Ernest Hives - Chair} is hoping that this EAC.7. will be used by meat Le CanadelHenry Royce's French residence early in 1928, with one of the modified engines fitted. I have to write to you on the subject of high and top heavy bodies, which appear to limit our good riding qualities by forcing us to use too rigid springs at the back. At the moment increased effectiveness of the shock dampers is much desired. Yours ever, R.{Sir Henry Royce} | ||
