| X.4244 X.4221. To R. {Sir Henry Royce} from E. {Mr Elliott - Chief Engineer} c. to BY. {R.W. Bailey - Chief Engineer} c. to HS. {Lord Ernest Hives - Chair} 7 E1/M31.5.23. RE. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) SLIPPER FLYWHEEL. X.4221. Regarding the alteration to the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) slipper flywheel, I agree that Mr. Bailey mentioned the alteration he had made to the method of securing the slipper flywheel springs, and it was agreed to go on with this. I was unaware however that the number of springs had been reduced from 16 to 8. This point was not raised, neither is it mentioned in the notes dictated during the discussion.
