| contd:- -2- R7/M15.12.21. I am not surprised to hear from Olley that these drives are not entirely satisfactory. Whether we can make them better I know not. I am inclined to recommend magnetic operating for 40/50 modified engine as we shall need double reducting gear and silent action. R.{Sir Henry Royce} P.S. It would be as well to take this opportunity as an excuse for finishing up with Rotax. R.{Sir Henry Royce} | ||
